Can the metal domes be soldered to a circuit board?
We 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.

What does the actuation force, return force, click ratio of the metal domes mean?
The actuation force is the amount of force that when you press the dome from opening to closed position. The normal force is from 80g to 5000g & we are using the grams for the unit. The return force is amount of force is that when the dome return back to the relaxed status. The click ratio is for the click feeling, the higher, the better click feeling. But when it’s too high may affect the life of the dome. Click ratio=Force- return force/Force

What’s the “Standard One Key Metal Dome Array”?
Our “Standard One Key Metal Dome Array” is the same as the “Standard Peel-N-Place Sheet” of Snaptron. “Standard One Key Metal Dome Array” is that the individual domes attached to a square of PET adhesive tap.

How do I make the metal domes fixed on a circuit board?
First, Our metal domes are stuck by means of the adhesive tap, we name it metal dome array. Second, we have two legs for the triangle shape, so you can insert the legs into the holes of PCB & then fixed.
