1), Y layout: switch the graphics and lines are respectively made in general complex copper double duplex printing lines, through hole metallization, the double line communication, and in the opposite welding components, with the metal guide as contact conduction touch labyrinth disc, after wiping with flat cable wire coils.
2), R layout: membrane switch panel layer, insulating layer, the circuit layer all by all sorts of different properties of the soft membrane, such as: PET, PC, PVC.
3, membrane switch partly film sheet
Panel material: the British ke figure Thai AUTOTEX goods with samwo international cooperation, thickness is not the same as standard, there are material (0.12 ~ 0.25 UM thickness) panel.
The thermal stability and shorten the treatment and prevention of adhesion of disposal mist PET sheet, as HT5, thickness is 125 um.
The thermal stability and shorten the treatment and prevention of adhesion of disposal of smooth PET sheet, have AUTOSTATCT3, CT4, CT5, CT7, thickness of 25100125 UM respectively.
Sand surface PET are: F series (fine), V series (coarse sand surface).Has a convex, double-sided by special chemical treatment of polar plate, sand surface can be printed bright window, glossy printing PVC, PC type of ink.
Hard coating of chemical treatment of PET: EBG (smooth) series EBA (mist).
