Pcb (printed circuit board) can be divided into single-sided, double-layered and multi-layered. There is no limit to the number of layers of multilayer boards. At present, there are more than 100 layers of PCB, commonly four-layer and six-layer boards. On the basis of Top Layer and Bottom Layer, the simple four-layer board adds power layer […]

Circuit board, also known as PCB, is an important electronic component, the support of electronic components, and the provider of electrical connection of electronic components. Circuit board proofing refers to the trial production of printed circuit boards before mass production. It is mainly applied to the process that electronic engineers conduct small batch trial production […]

It is estimated that the printed circuit board industry will not be eliminated in the last 50 years. After all, all electronic products need to be used, even if they are small. Every line has many things that outsiders don’t know, and there are many seemingly difficult but really simple technological processes. Today, I will […]

I believe that anyone who knows the production process of pcb proofing knows that electroplating is an indispensable and most important link in PCB, because the success of electroplating directly affects whether the PCB is qualified. Why can’t the quality be guaranteed in some PCB factories? It is because electroplating is not well controlled or […]

Nowadays, the rapid development of all walks of life and the rapid development of science and technology have promoted the great development of electronic products and the rapid development of SMT chip proofing. However, in this uneven industry, there will inevitably be some enterprises that cannot guarantee the quality of SMT chip proofing. In fact, […]

PCB design process PCB rule settings The design unit follows the unit set in canvas properties, where the unit is mil. Wire width is 10mil； minimum; The minimum distance between different network elements is 8 mil; The external diameter of the hole is 24mil, and the internal diameter of the hole is 12mil；. Line length […]

At present, the main products of SMT are: lead-free soldering process, lead soldering process and red glue soldering process. Moreover, its point calculation method is very similar, but many users don’t know much about the calculation of SMT patch points and how to calculate the cost. Some companies calculate one pad as one point, but […]

Nowadays, the use of PCB multilayer circuit boards in the market has become a popular trend, and with the development of the industry, the ability of many PCB manufacturers to develop and produce PCB multilayer circuit boards has become increasingly prominent. So, what are the requirements for the proofing of PCB multilayer circuit boards? Below, […]

Printed circuit boards (pcbs) are generally called printed circuit boards (PCBs). Printed circuit board proofing means that a small amount of samples are produced for testing before mass production, which also answers the question of PCB proofing sold in the market. Many electronic product manufacturers will find some professional PCB proofing manufacturers to cooperate with, […]

Generally, there are two kinds of SMT processes, one is lead-free process and the other is lead-containing process. Everyone knows that lead is harmful to people, so lead-free process meets the requirements of environmental protection and is the general trend. Shenzhen Yingcheng Electronic SMT SMD foundry adopts lead-free technology. The difference between lead-containing process and […]
