Difficulty boards, half-hole boards, thick copper, and fine circuit boards are all covered!PCB process flow four: circuit graphicsProcess flow diagram:Purpose:After drilling and through-hole plating, the inner and outer layers have been connected. This process creates circuit patterns to achieve ele

Maybe we will be surprised that the base material of the circuit board only has copper foil on two sides, and there is an insulating layer in the middle. So how can the two sides or multi-layer circuits of the circuit board be connected together so that the current can pass smoothly?Following the pr

PCB process flow 2: drillingIn the previous article, we introduced the PCB cutting process (click to learn more). This part comes to the PCB drilling process.PCB drilling: Drill holes on the board surface according to routing or structural requirements.Drilling process:Double sided board drillingCut

The first step of PCB process: cuttingPurpose of cutting: Cut large pieces of copper-clad sheets into small production boards of various required specifications.Drilling process: confirm the plate thickness/copper thickness/size → cutting → grinding → grinding corners → washing the plate → baking th

The spring breeze is strong and the Year of the Rabbit is auspicious. In this spring of sowing and nurturing hope, everything is revived and full of spring. Chongqing Electronic Circuit Industrial Park ushered in another major event. At 10:10 am on March 10, 2023, Chongqing Electronic Circuit Indust
