The customer always concern click feeling of metal dome, normal we can make is 50%+/-10%, so if customer wants higher click feeling, how can we improve it?

First, we should know the click feeling is not only relationship with shape of metal dome, force, re-force, stroke, etc., but also with the silicone keypad assembly. Several methods as below:

1. Adjust the force and re-force of metal dome, then increasing click feeling
2. Increase the stroke of metal dome
3. Well-designed silicone buttons with metal domes
4. Assemble metal domes in middle of silicone keypad, the more partial metal domes assembly, the more feeling worse.

What specifications you need to know when you inquiry for a metal dome array

Metal dome array is a kind of glued PET array & sheet that carries metal dome, which will be peeled easy from the released paper and place sticky on circuit boards, as a switch of electronic device.If you ask for a metal dome array,what specification do you need to know:

First,the metal dome parameter(detail please see FAQ What specifications you need to know when you inquiry for a metal dome)

Second,metal dome array size ,you should have CAD drawing for your metal array,or your circuit board instead,then we can design for you.

Third,what color do you want,Usually we have transparent and white,black is also available,but its not normal material.(detail please see our blog http://www.metal-domes.com/blog/2011/04/05/metal-dome-array-color/)

Do you know how to peel off the dome array from the sheet correctly?

The first way many people think is by hands, but I must tell you please don’t use hands.If you peel off dome array by hands, then you will stain the adhesive on the behind of dome array and have a fingerprint on it, leading to it won’t stick on the printed circuit boards firmly.The right way is to use the forceps or other toolings to peel off the dome array from the release liner, please aslo make sure the circuit boards no stain, dust and dirt.

Sometimes we get some metal domes inquiries from our customers, but they didn’t give us the specific parameters. I think maybe they also don’t know what the specification is. So we need to confirm with customers again to be clear what the correct metal domes customers need., which will take more time. So this time I will tell you about the specifications of metal domes:

• First,the metal dome shape: round, four-leg,Triangle, oblong or you need to custom special one for your product. You can choose the different shape metal dome according to your product design.
• Second, the force, what force is more suitable for your product? 60-500g is most used force for metal dome, also we have higher force, if you need, please contact us for more detail.
• Third, diameter, Usually diameter 4-12.2 mm is more popular. For more diameter choices, please contact us.
• Four, the surface finishing, Stainless steel, nickel plated, silver plated, gold plated, which one do you need? or other materials?
• Others, such as dimple or without dimple? If for Triangle metal dome series, with legs or without legs? if with legs, which type do you want? we have 0.8*0.8 & 0.8*1.5 &0.8*3.0, three kinds of legs for Triangle metal domes for your choice.

Now I think you are clearer about the parameters about the metal domes.Hope this will be helpful for you to choose a suitable metal domes for your product.
