The basic meaning of high Tg circuit board

When the temperature of high Tg printed circuit board rises to a certain threshold, the substrate will change from “glass state” to “rubber state”, and the temperature at this time is called the glass transition temperature (Tg) of the board.

In other words, Tg is the highest temperature (℃) at which the substrate remains rigid.

That is to say, the common PCB substrate material in the high temperature, continuous softening, deformation, melting and other phenomena, but also in the performance of the mechanical and electrical characteristics of the sharp decline, which affects the service life of the product (I think we do not want to see their own products appear in this case).

The main characteristics of high Tg PCB

Generally, Tg plates are above 130℃, high Tg is generally greater than 170℃, and medium Tg is about greater than 150℃.

PCB printed boards with Tg≥170℃ are usually referred to as high Tg printed boards.

With the improvement of Tg of substrate, the heat resistance, moisture resistance, chemical resistance and stability of PCB will be improved.The higher the TG value, the better the temperature resistance of the plate, especially in lead-free process, high TG is more widely used.

Therefore, the difference between general fr-4 and high Tg is as follows: under high temperature, especially under heat after hygroscopicity, the mechanical strength, dimensional stability, adhesion, water absorption, thermal decomposition, thermal expansion and other conditions of the materials are different, and high Tg products are obviously better than ordinary PCB substrate materials.

Application of high Tg plate in plate copying

High Tg plank in the application of copy plate at the present stage include: high-precision double-sided PCB PCB copy board, carbon oil filling hole PCB circuit board PCB copy board, high Tg PCB copy board, PCB PCB copy board, thick copper plate plane winding professional copy board, mixed media board PCB copy board, special base board copy board and customize various specific requirements printed circuit board, high Tg in every corner of the plate is widely used in industry.

HDI basic production process:

A、Brown multilayer circuit board to form Browning film on the surface of copper foil layer, and laser drilling on the surface of copper foil to form laser blind hole

B、 drill the multi-layer circuit board to form a mechanical drill hole

C、 The multi-layer circuit board is coated with copper to form a copper layer in the laser blind hole mechanical drilling, and then the multi-layer circuit board is electroplated to thicken the copper layer in the hole

D、The above multilayer circuit board is made of outer graphics, and the surface treatment of etched screen print resistance welding on the outer layer of graphics electroplating is carried out to obtain the finished HDI board
