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 […]

Pcb proofing and cutting dimensions ① Maximum panel size: 530 * 622mm (tinplate: 450 * 622mm/MAX. Depending on the equipment capacity) ② Pay attention to the latitude and longitude of boards with more than six floors (they must be the same), which will easily cause poor compression. ③ The size of the reserved surface of […]

The copper wire of PCB falls off (also known as copper throwing), and PCB factories all say that it is the problem of laminate, which requires its production factory to bear the bad losses. According to customer complaint handling experience, there are several common reasons for copper rejection in PCB factory: I. Process Factors of […]

Where are the OEM manufacturers in Changsha? Circuit board proofing refers to the trial production of printed circuit boards before mass production. It is mainly used in the process of small batch trial production in the factory after the electronic engineer designs the circuit board, that is, circuit board proofing. Generally, there is no specific […]

What is PCB high frequency board? Changsha high-frequency board refers to a special circuit board with high electromagnetic frequency, which is used for PCB in high-frequency (frequency greater than 300MHZ or wavelength less than 1m) and microwave (frequency greater than 3GHZ or wavelength less than 0.1m) fields. It is a circuit board produced by using […]

Metal core PCB is not very common in consumer products, but it can be found everywhere in industries, aerospace, lighting systems, power electronics and other fields that require high reliability. High-power systems generate a lot of heat, and it is necessary to quickly remove the heat to prevent component failure. Similarly, low-power systems may be […]
