In order to provide convenience for assembly, then the adhesive tape of metal dome emerges. Thus, how to assemble the adhesive tape on the printed circuit board is one of the difficulties to the metal dome manufacturers. Today, Best Technology would like to share something about how to assemble adhesive tape of meta dome with you. And the two kinds of assemble method as below:
1. How to assemble the single layer adhesive tape
Single layer adhesive tape just have one layer of PET which is silica gel, PPA or LCP plastic material. The thing we need to do is that peeling off the plastic material and pressing the adhesive tape with metal dome on it, then it can be firmly pasted on PCB. After that, we have finished the whole procedure of assembling adhesive tape of metal dome.
Tips: It is required to peel off the plastic material which aims at protecting the adhesive tape during transportation or storage.
2. How to paste double layer adhesive tape
Double layer adhesive tape is different from the single one. Compared with the single layer adhesive tape, it has an extra layer of spacer which can stop the PET from the dust. Meanwhile, the spacer can also improve the feeling of operation and avoid our hands are hurted by metal domes when assemble too quickly.
Tips: The plastic tissue on the back side should be abandoned and then tear off the adhesive tape on the front side to paste it on the printed circuit board. However, please keep an eye on the alignment of metal domes with the conductive parts during pasting.
The metal domes must be pasted above the conductive part of the printed circuit board and no deviation.
The adhesive tape can not be pasted several times.
Be careful when assemble and not be hurted by the metal domes.
