If the material tolerance goes to the lower limit and the above two factors are added, the adhesion may not be very firm.<\/p>\n\n\n\n<p>In general, our metal dome array&nbsp;is unlikely to have such a problem. For these special specifications, we can generally use a more viscous adheisve tape (such as 3M) to solve this problem. We have&nbsp;stronger adhesive materials for some special specifications of the snap dome sheet. However, there is a disadvantage is that it is not easy to tear after sticking, so you should stick to a good position at one time.<\/p>\n\n\n\n<p>Best Technology, your best partner in Asia, is professional for dome sheet\u00a0and dome switch\u00a0in China.
