Fr4 HASL Audio Amplifier 2 Layers PCB Board


Introduction

High frequency board usually use FR4 glass fiber lamination, but also the whole of the epoxy glass cloth repression, more uniform color the entire pcb board, bright. Density larger than the low frequency pcb board.

High-frequency electronic devices is the development trend, especially in the growing wireless networks, satellite communications, and information products to high speed and high-frequency, and voice communications products to large capacity and fast transmission of wireless, video, and data normalization.

 

 

Material:

(1) The dielectric constant (Dk) must be small and very stable, usually the smaller the better signal transfer rate

(2) The dielectric loss (Df) must be small, which mainly affects the quality of signal transmission, the smaller dielectric loss the smaller signal loss

(3) Consistent with the thermal expansion coefficient of copper

(4) Low water absorption, high water absorption will affect the dielectric constant and dielectric loss at the time of moisture.

(5) Other heat resistance, chemical resistance, impact strength, peel strength, etc. must also be good.
