Some customers have came across the problems that they can’t assemble the dome array on PCB firmly. I think maybe there are the
below issues for this matter:

Second, please use the the forceps or other toolings to peel off the protective film of dome array, please don’t use the hand;
Last but not least, please press a little after you stick it on the PCB.
