Now the most popular used for metal dome array is the double-layers. The top layer is the Mylar, transparent with 0.05mmthickness; Bottom layer is Spacer, we have the white and transparent, two kinds materials. The thickness is 0.05mm and 0.075mm; Last we have a support layer to prevent the metal dome from the dust, dirt,etc..

Monday, July 18th, 2011

Do you have the questions of the metal dome array deviation problem? & do you also worry about it will affect the use of the dome array. Here we have this problem, explain in detail the existence of the metal dome array deviation problem.

1, The first metal dome array is made by laser, and assembly by fixture, there is a +/-0.15mm tolerance range;
2, Metal dome array of empty slots in diameter larger than metal domes as 0.20mm, so when the metal domes in the slot is ok; normal range
3, When metal dome array installed on the PCB, in fact, does not affect the clink feeling.

Metal dome array with a slight deviation in the production process is an inevitable phenomenon, is within the tolerance range, it does not affect the use of metal dome array installation. But exclude more serious deviation, this time we will test it by hand to correct them there.

Raw edges of metal dome array

Saturday, July 10th, 2010

Sometimes when we make the metal dome array which will cause the raw edges, so why is that and how can we slove that?

The reasons and solutions as below:
1. The mold for metal dome array outline not in balance—we should adjust the mold;
2. Blade for outline mold isn’t shape—handing the blade of mold;
3. Big gap between upper and lower molds—-adjust the specifications;
4. Thinner material—use the thicker material.

For the unqualified products, we can’t let them out of factory, we have a very strict quality control system to ensure the quality of our metal dome array. Please don’t worry about the quality of our products.
