SMD tactile switch is a widely used chip component, mainly produced through surface mounting technology. It is a switch type mainly used in various electronic products at present. Since there are many manufacturers of SMD tactile switches, and the products have various sizes and specifications, and the quality is also uneven, this leads to customers not knowing how to make a choice when choosing. The following is based on the structure and working principle of SMD tactile switch. Select the appropriate SMD tactile switch.

SMD tactile switch is mainly divided into the following two types according to different design principles. One is to use the metal dome inside the switch to turn the switch on and off. The feel of this switch is relatively good, because it is made of metal. When the switch button is pressed to a certain extent, there will be a ticking sound. , this kind of feedback is very good. Many mobile phones now use this principle in their design, such as virtual buttons. In order to make them have the same feel as physical buttons, various vibrations and sounds are designed to create a feeling that is the same as physical buttons. a feeling of. The other is to use conductive rubber to turn the switch on and off. The feel of this type of switch is slightly worse than the previous one, but the contact resistance is large, about 10,000 times that of the previous one.

Structure of SMD tactile switch

The SMD tactile switch is mainly composed of five parts: cover, button, dome, base and pins. The cover is mainly used for sealing protection to prevent dust and other pollutants from corroding the internal parts of the switch; the main function of the button is to withstand the pressure of external force, and then conduct the pressing force to the dome; and the dome is an SMD tactile switch A very important component in the circuit breaker, it mainly relies on changes in the force of the dome to turn the switch on and off, forming a closed circuit; the function of the pins is mainly to connect with the circuit.

SMD tactile switch working principle

The working principle of the SMD tactile switch: When the button of the switch is pressed, the dome inside the switch will deform under the action of pressure and contact the solder tab, which will connect the pin circuit of the switch; and when the dome When the pressing force is removed, the dome will immediately separate from the solder tab and return to its original state. At this time, the two sets of pins of the SMD tactile switch are no longer connected, causing the entire switch circuit to appear disconnected.

The production and manufacturing of SMD tactile switch can be well understood from the structure and working principle. So how to choose a suitable product? When the patch clear switch is used, in order to improve the performance of the switch, the contact resistance will be reduced. Therefore, customers will choose the material of the chip clear switch. Both brass and phosphor copper have the function of reducing resistance. In addition, the resistance can be reduced by surface treatment of the metal dome. When choosing a tactile switch, you must choose a reliable product, mainly for stable performance and safe and continuous operation.

The metal dome plays an important role in the SMD tactile switch, so when choosing a suitable tactile switch, the product quality of the metal dome should also be considered.

As we all know, the choice of materials plays a crucial role in determining electronic devices performance and lifespan. Among the various options available, gold-plated metal domes have emerged as a preferred choice for many applications. In this blog, we explore the reasons behind the growing popularity of gold plating and its benefits in enhancing the functionality and beauties of electronic components.

Various Types of Metal Dome in Electronic Devices
Normally, the materials affect the life cycle of metal dome directly, and there are many types of materials: stainless steel material, Nickel plated material, Silver plated material, Gold plated and Phosphor bronze plated.
Generally speaking, the material with surface treatment will have a better conduction performance than that of stainless-steel material, especially the gold-plated dome, having the lowest resistance and the best conduction performance, followed by the silver plated, nickel plated, and stainless steel metal dome. And surely the cost of gold plated is the highest.

Advantages of Gold Plating Metal Domes
Among the various options available, gold-plated metal domes have emerged as a preferred choice for many applications. Herein, we explore the reasons behind the growing popularity of gold plating and its multifaceted benefits in enhancing the functionality and beauty of electronic components.

1.Corrosion resistance
One of the primary reasons for opting for gold-plated metal domes is the superior corrosion resistance they offer. Electronic components are often exposed to harsh environmental conditions, including corrosive gases and liquids. The gold layer acts as a protective barrier, shielding the metal domes from corrosion and ensuring the stability and reliability of the components over an extended period.

2.Electrical conductivity
Additionally, the gold layer improves the electrical conductivity and thermal conductivity of the metal domes. Metals are inherently good conductors of electricity and heat, and a gold coating can further enhance these properties. This improvement in conductivity ensures more efficient transfer of electrical and thermal energy, effectively reducing contact resistance and enhancing the quality and efficiency of signal transmission.

3.Oxidation resistance
In another aspect, the gold plating increases the oxidation resistance of the metal domes, thereby extending their lifespan. Gold is highly chemically stable and resistant to oxidation and corrosion, which helps maintain consistent performance of the domes in complex working environments.

4.Good appearance
Furthermore, the gold coating also enhances the aesthetic appeal of the metal domes, elevating the product’s quality and level. The attractive color of gold can improve the overall texture of the product. In modern society, where appearance is increasingly valued, the aesthetic appeal and quality of electronic components, which are often on display, are equally important.

Anyway, the use of gold-plated metal domes in electronic components has become a strategic choice, driven by the manifold advantages they offer. As technology continues to advance, the adoption of gold-plated components is expected to rise, marking a golden era for electronic engineering. Whatever assemble in PCBs, flex circuits or in tactile membrane switches, it is the best option for you. You can contact us feel free when you want more information shared.

Air vent hole (air vent slot) is a small path that located around the metal domes or between domes, which is an important element for the normal operation of the dome array. It is available for almost of applications, so that when we press the metal dome, the air will go out through the small path. Therefore, in another word, air vent hole is related to the clicking feel and function of the dome array or tactile membrane switch.

The location of the vent slot is extreme vital for the function of the whole product. Normally, there are three ways to design the vent holes, each way has its advantages and depends on the specific requirements. Herein, we would like to introduce these ways to make you sense to them.

What is the importance of the air vent hole on dome array?

Typically, the vent hole serves as a pathway for air to release, maintaining balanced pressure and preventing potential issues such as sticking, inadequate response, or non-operational switches. The primary role of the air vent hole is to equalize pressure between the metal dome and the substrate. When a user presses a metal dome, the air underneath it needs to escape to ensure a stable and dependable tactile response. The presence of the air vent hole facilitates the immediate release of trapped air, allowing the dome to collapse and establish proper electrical contact. Without the vent hole, the dome may not perform optimally, leading to inconsistent or unresponsive keystrokes. Therefore, when pressing the snap dome, a vent slot is essential to prevent the compression of air underneath.

The ways to design air vent hole

There are three ways to make the vent holes on the dome array, which including:

1.Design air vent holes between metal domes and spacer

The first way is the most popular and easy to make, that is designed between the metal domes and spacers, just like below image. By this way, we can design the vent slot everywhere we want, and the path can longer or short. It depends on the distance between the two metal domes. But there is a tip that you must know – by this way, the air vent slot must between the spacer between the two metal domes, so that the air can be vented smoothly.

2.Make the small opening hole on the top layer of dome retainer

If your space between metal domes is limited, make a small opening on the dome retainer also is a good idea for air flowing. It can designed according to your preference.

3.Make hole on the PCB

In almost way, the dome array or metal domes are always assembled with PCB or flex circuits. So you can make a hole on the PCB like below image, by this way, the air can be flowed out through this small hole.

Each of these vent hole placements has its advantages and may be selected based on specific design considerations, such as the desired tactile response, overall switch performance, and manufacturing requirements. The choice of vent hole placement can impact factors like actuation force, key feel, and the prevention of issues like sticking or poor responsiveness in dome array applications.

In electronic product production applications, dome array installation on PCB has become a topic of concern. In complex printed circuit boards (PCBs), there are some issues that continue to attract attention – the problem of dome array installation tilt. Best Technology decided to explain this phenomenon and give you an in-depth introduction to dome array.

Whether it is the selection of materials, the stamping technology of the dome, or precision manufacturing, any lax operation will affect the subsequent application of the metal dome or dome array. During the assembly process, the dome array needs to remain stable and flat on the PCB board. However, some manufacturers have encountered a troublesome situation where the dome array is initially flat when assembled but gradually tilts over time. This tilt creates the risk of dust penetrating the dome array, causing conduction damage and potential operational issues.

Often to improve performance and durability, metal domes require a coating, usually involving gold or nickel plating. This protective layer protects the dome from corrosion and wear, ensuring continued functionality over the long term. At the same time, during the assembly process, the metal dome needs to be assembled first onto a double-layer structure, usually consisting of an upper polyester film and a lower spacer layer.

Looking closely, for the dome array assembled onto the PCB board, the root cause of this problem lies in the construction of the double-layer structure dome array. Specifically for the dome array, the thickness of the upper polyester film layer is approximately 0.05mm, and the thickness of the lower spacer layer is approximately 0.075mm. When using a high-height metal dome, such as a triangular or four-legged metal dome (height range is 0.4mm to 0.7mm), the height difference between the dome and the spacer layer is relatively large. Once the dome is close to the edge, it will cause shrapnel The patch becomes warped.

So how to solve this problem?

To solve this problem, we can start from two aspects, a two-pronged solution: first, the supplier provides drawings, and when designing, the shrapnel should not be too close to the edge, leaving enough space to prevent warping. Second, we can thicken and add Glue the spacer layer to prevent the elastic patch from lifting. This modification ensures a more secure connection, prevents dome array tilting and maintains optimal performance.

Dome array is a main component in electronic products, so it must undergo strict production to ensure the production quality of the product. At the same time, designers with rich experience are required to design solutions more accurately and avoid problems encountered in applications. Also selecting a dome with appropriate height specifications can help manufacturers proactively address tilt issues. Best Technology strictly controls quality control to ensure that metal dome arrays meet the necessary standards and can provide reliability and longevity in electronic applications.

In short, understanding the difference between the structure and production process of metal dome arrays and dome specifications is crucial to solving the installation and use problems of dome arrays in PCB boards. The problems that may be encountered when applying in products are some minor problems. This can be avoided with minor design changes. Reliability and suitability for dome array applications are ensured through thoughtful design and functional enhancements within the structure.

The above is a detailed introduction to how to deal with the installation tilt problem of metal dome array in PCB board. If you have other questions about metal dome or dome array, please leave us a message.

A membrane switch is a type of user interface that consists of several layers of flexible materials sandwiched together. It is commonly used in electronic devices and control panels to provide a user interface for input or control. The layers typically include a graphic overlay, circuit layer, and adhesive layer, and assemble them into a whole product that is called membrane switch.

Before dive into the assemble process, we should know the structure composition about a membrane switch. In generally, all the tactile switches are made by six layers, whatever it is the simplest PET membrane switch or the complex fiber optical tactile switch. The six layers are including:

1.Graphic overlay

The graphic overlay is on the top side of the membrane switch, which can be designed various legends and colors on it. There are commonly two printing methods that print the graphic, one is traditional screen printing, and another is digital printed technology. Both two are excellent way to print, but digital printed is mainly used for printing the gradient colors, like dark blue to light blue. By this way, the overlay can be shown a more beautiful and advanced appearance.

2.Overlay spacer

The overlay spacer is typically a layer that provides separation between the graphic overlay (the visible top layer with the buttons or graphics) and the circuit layer (the layer containing the conductive traces). This spacer layer is crucial for preventing unintended contact between the overlay and the circuit layer, ensuring that the switch functions properly and only registers press when intended.

3.Dome retainer

The dome retainer is a part of the membrane switch that helps hold the metal dome onto the correct place, ensuring they are properly aligned with the corresponding circuit traces. It can help to maintain the integrity of the switch’s design and misalignment or unintended actuation.

4.Circuit spacer

A circuit spacer just like the overlay spacer in a membrane switch, it refers to a material that is used to create separation between the dome retainer and lower circuit layer. When a user presses a key or activates a specific area on the graphic overlay, allowing the conductive elements on the overlay to make contact with the corresponding traces on the circuit layer beneath.

5.Lower circuit

This layer usually consists of a flexible circuit board (FPC) or a polyester (PET) or the printed circuit board (PCB) that has circuit traces or conductive elements printed or etched onto it. These traces serve as the conductive pathways for transmitting the electrical signals generated by the user’s input to the electronic device or system connected to the membrane switch. It plays a crucial role in the functionality of the switch by facilitating the completion of electrical circuits when the switch is pressed, thereby registering the desired input.

6.Back adhesive

The back adhesive is the bottom layer of the membrane switch, we always use the 3M adhesive as the bottom layer. The primary purpose of the back adhesive is to provide a strong and reliable bond between the membrane switch and the substrate or surface to which it is applied. This adhesive layer ensures that the membrane switch stays in place during regular use and does not peel off or detach.

 The choice of adhesive is crucial, as it needs to adhere well to various materials, including metals, plastics, or other surfaces commonly found in electronic devices or equipment. Additionally, the adhesive should be durable enough to withstand environmental conditions and temperature variations.

These are the basic layers of the tactile membrane switches, if you have more questions about the structure, welcome to contact us.

Membrane switch buttons are ubiquitous in our daily lives, found in remote controls, medical devices, and countless other gadgets. What makes these buttons tactile and responsive is the presence of a metal dome. The metal dome is essentially a small, spring-like structure that sits beneath the graphic overlay of the membrane switch. When pressure is applied to the button, the dome collapses, completing the circuit and recording the user’s input.

In an intricate array of electronic devices, a membrane switch button may look like a small component, but it plays a vital role in user interaction. The center of this unassuming button hides a gem – a metal dome. Let’s delve deeper into the importance of metal domes in membrane switches, exploring their functionality, longevity testing, and the meticulous design that shapes our tactile experience.

Think of the metal dome as the conductor of a silent orchestra within the device. Its main function is to provide tactile feedback, giving users a satisfying feel every time they press it. This tactile response not only enhances the user experience, but also ensures input accuracy. The metal dome’s ability to spring back to its original shape after each press is critical to the switch’s longevity and reliability.

Metal Dome Detection

When the membrane switch is in use, the metal dome also has a service life, and understanding its service life is crucial to the reliability of the membrane switch. Manufacturers use rigorous testing methods to determine how many drives a metal dome can withstand before its performance begins to degrade. This ensures that devices equipped with membrane switches maintain their responsiveness over time, providing users with a consistent and reliable experience.

There are several aspects of precision testing for metal domes, including grinding tool accuracy, dome size, dome performance testing, and conductivity testing to test the quality of the dome. Best Technology specializes in the production of metal domes and strictly controls product quality. By using domes in products, they can perform their functions stably.

Metal Dome Design

Metal dome design is an art in itself, with different shapes, sizes and materials affecting the tactile feel of the switch. Some metal domes are designed to provide a lighter, more cushioning feel, while others provide a crisp click sound. Manufacturers carefully select the appropriate dome design based on the intended application and user preference. Haptics, while often overlooked, greatly improves the overall satisfaction of interacting with a device.

As technology develops, so does the development and production of metal domes. Engineers and designers are constantly pushing boundaries, experimenting with new materials and innovative designs to further enhance the tactile experience. From ultra-thin domes in stylish smartphones to solid domes in industrial control panels, metal domes continue to play a key role in the evolution of user interfaces.

All in all, the metal dome in the membrane switch button is a silent worker, hard at work behind the scenes to give us a tactile and responsive experience. As we marvel at the advancements in electronic devices, let’s take a moment to appreciate the small but important innovations that make our interactions seamless and enjoyable. Although the metal dome is hidden, its impact on the user experience is anything but subtle.

The metal dome can be used in tact switches and key switches, which are electronic switches with integrated panel and switch functions. The metal dome is mainly composed of four parts: panel, upper circuit, isolation layer, and lower circuit. When the Poly dome membrane switch is pressed, the contacts of the upper circuit deform downward and make contact with the plates of the lower circuit. After releasing the finger, the contacts of the upper circuit bounce back, the circuit is disconnected, and the circuit triggers a signal.

In the production of metal domes, the stamping method can be used to mass-produce metal domes. Stamping has strict requirements on size. For products with a small quantity, a knife mold can be used. During the production process, our inspectors will use calipers to check from time to time to see if the dimensions of the metal domes are accurate. At the same time, check whether the mold is deformed. If the mold is deformed, production should be stopped immediately and a new mold should be made. For products with a larger quantity, steel molds are used, which have less deformation and more accurate dimensions.

The metal dome also needs to be tested after production. The first is functional testing. Here, the strength and feel of the metal dome are mainly tested. The pressing force of the dome will affect the use of the product. When installed in a Poly dome membrane switch, if the pressing force of the dome is inappropriate, it will affect the user’s experience, or there will be no effect after pressing. Functional testing is to sort out unqualified products. Best Technology has rich production experience, so in the testing of dome strength, the pass rate is greatly improved.

The life test of the dome is also part of the test, but the life test takes a longer time than other tests, because when pressing the traditional Chinese medicine to simulate the normal pressing force, you have to wait for the dome to rebound before continuing to press. Therefore, the entire testing process takes a while, so the spot check testing method is used in life testing. Best Technology’s metal dome has a service life of up to 5 million times. Therefore, it is very popular among suppliers in the metal dome industry.

When a metal dome is installed in a Poly dome membrane switch, various uncertain factors will affect the service life of the dome. After testing, our Poly dome membrane switch has a service life of at least 1 million times. Therefore, whether installed in machine operation interfaces or frequently used switches, domes can perform their functions stably.

Main features of metal domes
The metal dome is compact and portable, easy to carry and pack, bears less express delivery costs and is cost-effective. Metal domes can be designed in different shapes and heights according to different requirements. If you need to install LED lights for light transmission, the metal dome can be designed to be hollow to facilitate light transmission. In short, we can design a suitable metal dome according to the user’s product needs.

The metal dome needs to be sealed during use. Improper use of the metal dome will also affect the service life of the metal dome. Best Technology has decades of production experience in the dome industry. For the production, testing, and packaging of metal domes, it has always been Best’s production goal to ensure the quality of the products through quality inspection.
