FAQ

Q. Can the domes be soldered to a circuit board?

A. Not recommended. When the domes are pushed, the feet actually move outward slightly. When soldered to a circuit board, the feet of the domes are restricted from their natural movement. This restriction can negatively affect the tactile response of the domes,and in some cases, cause irreparable damage to the domes or break the solder joint.

Q. What is the purpose of a dimple in the center of a dome?

A. Various Snaptron domes have a dimple located in the center of the dome. Typical depth of the dimple is .001” to .002” but may vary depending on the dome style. A dimple is used to reinforce or improve the dome contact with the PCB.
