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.
