Advantages and functions of heavy copper PCB
Functions:
The application of heavy copper PCB in PCB proofing is almost everywhere, and its application field is very broad, including all kinds of home appliances, high-tech products, military, medical and other electronic equipment. Heavy copper PCB has excellent extension performance, high temperature, low temperature, corrosion resistance, so that electronic equipment products have a longer service life, but also to simplify the volume of electronic equipment has a great help. In particular, the need to run a higher voltage and current of electronic products is the need for heavy copper.
Advantages:
In PCB proofing, heavy copper PCB has excellent strength and processing adaptability. In addition, it is also suitable for various processes and systems such as unit wall plate, flat lock type system, vertical bite system, BEM system, rain drainage system, etc., and can also be applied to various processing requirements required by these systems.
Solution of filling glue for heavy copper PCB with inner copper thickness ≥ 4oz
For the PCB with heavy copper foil design, in order to ensure the full filling of glue, the printing resin or PP powder is usually used. However, this solution has the problems of long process and difficult to control the thickness of dielectric layer. SP adhesive sheet can achieve the characteristics of high glue content and high thickness. It has great advantages for heavy copper glue filling and can effectively solve the problem of heavy copper glue filling.
Advantages of SP Prepreg
The use of high heat resistant resin system, with high heat resistance
Adopt low expansion coefficient system
Super high resin content and good porosity make it has a very excellent filling capacity
Special glass fiber structure eliminates stress points and improves reliability.
