What are the ways to distinguish the quality of PCB circuit board materials?

As the demand for PCB circuit boards increases, some manufacturers try to meet customer needs by reducing material costs and process costs. So, what are the ways to distinguish the quality of the PCB circuit board material? Let’s introduce for everyone.


1. A high-quality PCB circuit board should meet the following requirements:


  1. The line width, line thickness and line distance of the line meet the requirements;

  2, the copper skin is not easy to fall off under high temperature;

  3, the copper surface is not easy to oxidize, which affects the installation speed;

  4. The PCB shape is not deformed, and the shell is not deformed after installation, and the screw holes are misaligned; the hole position of the circuit board and the deformation error of the circuit and the design are within the allowable range.

2. The appearance of the PCB circuit board can be analyzed and judged through three aspects;


  1. The size and thickness of the circuit board. Customers can measure and inspect according to the thickness and specifications of their products.

  2, light and color. The appearance of the circuit board is covered with ink, which plays a role of insulation. If the color of the board is not bright and there is less ink, it means that the quality of the circuit board is defective.

  3. Appearance of weld. The circuit board has many parts, if the welding is not good, the parts are easy to fall off, which seriously affects the welding quality of the circuit board. It can be seen through careful identification.


The above is the method of distinguishing the quality of the PCB circuit board material, I hope it will be helpful to you. iPcb is a high-tech manufacturing enterprise focusing on the development and production of high-precision PCBs. iPCB is happy to be your business partner.
