How to clean the metal domes?

Saturday, November 7th, 2020

The cleaning of metal domes is a key step in determining the quality of metal domes. Why do you say that? Because if the metal dome is not cleaned well, it will affect the conduction of the circuit board, which is a functional problem.

The cleaning of the metal dome relies on UL-trasonic waves and uses special chemical reagents for cleaning. It takes about one hour to clean, then dry for one hour, and finally pack it out. If the cleaning is not thorough, there may be lamination, which will produce rust and stains. Our company has been professionally making metal domes for more than ten years, so there is no problem cleaning problem, and we have not received any complaints from customers.

Wednesday, December 11th, 2019

We have the triangle metal dome with legs is divided into three items: short legs 0.8mm, middle legs 1.5mm, long legs 3.0mm. Choose the suitable legs based on the thickness of your PCB board.

  1. Insert the legs into the hole of the circuit board first. Generally, the legs length should be longer than the thickness of the circuit board.
  2. Bend the legs on the back of the circuit board to fix it, or paste a little transparent glue on it.
  3. The triangle metal dome with legs is generally suitable for toys, or high force products.

Do the metal dome force will become smaller after long time use?

Wednesday, March 1st, 2017

After a long period of using metal dome, do the force will be have some changed? Of course, the force will be reduced to a certain extent, and this process is to reduce the life of metal dome. Please see this formula: (A-B)/B, (the beginning force is A, according to a certain number of times down to the B), when this ratio reaches a certain value, the function of metal dome will be affected, or even dead key.

The change in the force of metal dome is related to the life of metal dome, the longer life, the longer force. And the life of metal dome is based on the material and process flow, so we welcome to purchase our company metal domes, which are high quality and reasonable price.
