How to calculate PCB impedance ？

Nowadays, the most commonly used impedance calculation tool in the PCB industry is the Si9000 which is provided by Polar. Firstly, you need to select the corresponding impedance model, and input the corresponding line width, line space, dielectric thick

What is the difference between Rogers RO4003C and Rogers RO4350B?

Roger RO4000 series high frequency PCB material is made by glass fiber reinforced hydrocarbon/ceramic substrate (not PTFE), which is characterized by low loss, low tolerance and excellent high frequency performance

FR-4 Copper Clad Laminate（CCL）material grade

In addition to making some ROGERS high-frequency PCB, TACONIC microwave PCB, ARLON microwave RF PCB and F4BM microwave radio frequency print circuit board, the most commonly used material in Shenzhen Vip Circuit Co., Ltd. is FR4.

PCB prepreg quality inspection method

The prepreg(PP) is the material that must be used to make multilayer PCB which is a sheet material composed of a resin and a carrier.

Introduction to Rogers RO3010 high frequency materials

Rogers RO3003 & RO3010 laminates have a lower Dk value of 3.00 (± 0.04), its TCDk is also much lower (Z-trend -3 ppm/°C). TMM materials are an exception. Although TMM materials have very high Dk values, such materials still have lower TCDk values.

PCB must take the road of green development
