What is a Halogen-Free PCB?

WHAT IS A HALOGEN-FREE PCB? As the name suggests, PCBs free of halogens are halogen-free PCBs. Here halogen refers to chlorine, fluorine, iodine, astatine, and bromine. Halogens are very harmful to life. To generate a halogen-free PCB, you always need a halogen-free lamination of copper clad. Halogen in PCBs Halogens are not a substance or […]

What is FR4 PCB material?

FR4 is the commonly used material in PCB manufacturing. It’s a versatile material and has a balance between cost and performance. That is the reason why FR4 material is widely applied in single-sided, double-sided, and multi-layered boards. In this article, you will find out more about: What does FR-4 Stand for? Beneficial Properties of FR-4 […]

Why FR4 Material is Commonly used in PCB Fabrication?

FR4 material is the most common grade dielectric material that is used in the fabrication of circuit boards. This material is incorporated in single-sided, double-sided, and multi-layered boards. Here are a few qualities of FR4 materials that make them popular: Wide range of operating temperatures (50°C to 115°C) Higher Tg value (about 180°C) Offers decent mechanical […]

Multi-Deformation Structure PCB Board Copper Pour Problem

The significance of copper coating is to reduce the impedance of the ground wire and improve the anti-interference ability, reduce the voltage drop and improve the efficiency of the power supply. Connecing with the ground wire can also reduce the loop area. Also for the purpose of making the PCB as undistorted as possible during […]

PCB base material – knowledge base

The base material of circuit boards can be divided into two categories: rigid PCB base materials and flexible PCB base materials. Rigid material: Generally, an important variety of rigid base materials is copper-clad laminates. It is made of reinforced material (Reinforcing Material), impregnated with resin adhesive, dried, cut, and laminated into a blank, then covered […]
