In the SMT patch proofing process of the SMT small-batch patch processing plant, a white spot or white spots in Circuit Board will appear on some circuit boards. What is going on? The appearance inspection also accounts for a large part of the quality inspection of electronic processing. The circuit board with white spots is…
In SMT patch proofing, some orders require only a small number of orders, such as one or two pieces or two or three pieces, and do not need to be sampled on the machine. This may be an SMT patch-proofing processing method of manual placement. IC is the English abbreviation of Integrated Circuit (Integrated Circuit)….
Nowadays, the sensitivity of electronic equipment is getting higher and higher, which requires the equipment to have a stronger anti-interference ability. Therefore, in the PCB design, how to improve the Interference in PCB Board has become a key issue of the circuit board project. Therefore, methods to reduce noise and electromagnetic interference in PCB design:…
When customers customize PCB products, they will produce more in quantity to prepare for their PCB projects. Over time, the PCB board will expire. So, what are the hazards of using expired PCB circuit boards? 1. Expired PCB fabrication may cause oxidation of surface pads Oxidation of the solder pad will cause poor soldering, which…
The advantages of the Aluminum PCB include the following 8 points 1. Heat dissipation: High temperatures can cause serious damage to electronic equipment, so it is wise to use materials that help heat dissipation. In fact, aluminum can transfer heat from important components, thereby minimizing its harmful effects on circuit boards; 2. Environmental protection: Aluminum…
PCBA is through the entire process of PCB blank board SMT loading, and then DIP plug-in; SMD and soldering are the core links in PCB circuit board. So, what are the requirements for PCBA processing flow patch? 1. According to the customer’s Gerber file and BOM list, make SMT production process files and generate SMT coordinate…
The charging USB PCB board is the center for the USB connecting interface gadgets due to its popular usage. It aids in transmitting data quickly in an efficient way. Different brands of USB 2.0 are in the market space, but the use of its application becomes difficult. This is due to a series of challenges posed…
High-level PCB is usually defined as 10-20 layers or more high-level multi-layer circuit boards. Compared with traditional FR4 PCB products, high-level PCB has the characteristics of multiple thicknesses, multiple layers, dense lines, multiple through holes, large cell sizes, and thin dielectric layers, and requires internal space, layer alignment, impedance control, and reliability. High; is mainly…
The PCB circuit board is a complete device only after PCB processing and can be used in application electronic products. The PCBA process is a combination of the SMT process and the DIP process. Today, we will share with you the steps involved in PCBA Electronics Manufacturing by Shenzhen PCB manufacturers. 1. Single-sided DIP cartridge…
How to Design The Vias in High-Speed PCB? Do the following as much as possible in the design: 1. Choose a reasonable size. For multi-layer general-density PCB design, it is better to use 0.25mm/0.51mm/0.91mm (drilled holes/pads/POWER isolation area) vias; for some high-density PCBs, 0.20mm/0.46 can also be used For vias of mm/0.86mm, you can also…
