The factors of making circuit for membrane switch should be attention

 1. Choose a larger net frame, screen tension.Net frame, relative deformation is small, easy to operate.Net frame stretch tight closely, is advantageous to the printing material and screen can be rapidly separated, so more advantageous for high viscosity pulp silver.


  2. Manual glue, to do the glue with smooth surface evenly.Is 4 times, but there are special circumstances, to inspect the loose consistency of the sensitive glue and decided to glue the number of times.First pass on glue, repeatedly in evenly on both sides of screen scraping, make sensitive glue even fill mesh.Then the baking in the oven (note: every scraping gum, must be thoroughly dry), the second, three times in the screen printing on surface after drying, the blow a fourth times glue, in scraping ink surface drying at a time.


  3. Print screen and films together, time shoulds not be too long, otherwise the development difficulties, also shoulds not be too short, or it will cause no resistance to seal, dilatation of the line.Then put in the drying system of good screen JK flush with low water pool, stay just version of photosensitive glue, enhancement after fully dry.


  4. Drying screen to check the presence of pinhole, bubbles, and repair.Again after drying, for a second exposure, to combine just version of photosensitive glue to thoroughly, firm, to improve the network version of the resistance to India.
