1Layer Glass PCB

With the rapid development of electronic technology, especially the terminal products with light, thin, short and small as the development trend, higher requirements for its basic industry, printed circuit board industry, such as high density, small size and high conductivity, are put forward. Under this background, PCB technology is developing rapidly, and various industries in weak current field, such as computer and peripheral auxiliary system, medical equipment, mobile phone, digital camera, communication equipment, precision instrument, aerospace, etc., have put forward many specific and clear technical specifications for the process and quality of printed circuit board.

As a PCB equipped with IC chip, double sided wiring printed circuit board has attracted much attention. The structure of double-sided wiring printed circuit board is that there are conductive layers on both sides of the insulation layer (inside and outside the surface), and then through holes or blind holes are formed at any position of the pattern inside the table. The inner wall of the printed circuit board is electroplated or filled with conductive adhesive to make it conductive.

Epoxy glass or polyimide material is usually used as the insulation layer for PCB. The conductive layer is copper foil pasted on the surface of the insulation layer. Because the adhesive effect of the adhesive decreases gradually after a long time of use, the contact between the conductive layer and the insulating layer is not close, and the conductive layer floats on the surface of the glass plate, the surface of the whole circuit board is not smooth, and the conductive layer is easy to damage and fall off In order to make the copper foil thinner, we try to use the extremely thin copper foil material, but the current situation is still that the thickness is about 12um.

Transparent glass based double-layer circuit board, the glass substrate and the conductive circuit are fused and closely connected, and the surface of the glass substrate is flush with the upper surface of the conductive circuit, the surface of the whole high conductivity transparent glass based circuit board is smooth, the conductive circuit is not easy to be damaged, and the conductivity is strong.
