Membrane Switch Manufacturers Solve the Problem of Large Resistance of Membrane Switch Circuit

What are the main reasons for the large resistance of the membrane switch Circuit?

(1) The silver paste was not sufficiently stirred before printing.

(2) After the printing, the baking time of the line is insufficient and the temperature is low.

(3) The mesh mesh used is too thin.

(4) The silver paste of the printed circuit is too thin.

(5) The silver paste is too thin, and the diluent is added too much, so that the amount of silver is too small or a non-silver pulp-specific diluent is used.

(6) The graphic design of the line is unreasonable.

(7) The quality of raw materials such as silver paste is not good.

If the above reasons occur, the membrane switch factory can take the following methods to solve the problem:

(1) Before printing, ensure that the silver paste is fully stirred. When adding silver paste, it must be thoroughly stirred.

(2) Master the control of baking time and temperature.

(3) Replace the mesh with a thick mesh and make a qualified screen.

(4) Change the plate making method, you can consider using a thick plate.

(5) Check the concentration of silver paste, pay attention to the control of the addition of diluent, and ensure the use of thinner with the silver paste.

(6) Check whether the circuit design is reasonable and make necessary improvements to the designed circuit.

(7) Replace the raw materials such as silver paste that meet the requirements of the backlight switch.
