The scrap of Metal dome array

Saturday, August 18th, 2012

The scrap of metal dome array has caused by Laser-cutting, and will create some problems in the assembly process.How do we find a way to solve this issue?

We generally peel off the scrap around of the metal dome array by hand, but some still exist in the center of dome array holes, and it can’t peel off by hand. The reason is that if the laser cut not very deep, then the middle scrap is possible peel off together with dome array,so it’s very inconvenient for assembling.

So how do we solve this problem?
1, First,we must adjust the machine to cut deeply,let the scrap can’t peel off together with dome arrays;
2, Another way, make the middle scrap to cut through, so that it’s very convenient for assembling. But this is a bit difficult.

The metal dome array adhesive sheet is not strong?

Tuesday, May 29th, 2012

Does the metal dome array adhesive sheet is not very strong? Recently we have received complaints of the two guests on the adhesive is not very strong. In fact, this is the same as we usually make the metal dome array.
Then how could this problem happen? We analyze and have the following specific reasons:
1, The metal dome for metal dome array is four-leg metal dome and triangle metal dome, they are with very high force and stroke;
2, The dome arrays of customers is not very adequate to stick, too little. Generally to maintain a minimum of 2mm distance to edge.

Generally speaking, our regular dome array can not have this problem. For this kind dome array, we can use the stronger adhesive sheet to solve this problem now. Please don’t worry about this issue.
