PCB copy board (circuit board copy board) copy board analysis panoramic camera parking technology

The mechanical driving part is driven by the CAM spindle to drive the feeding mechanism, and the striking arm of the feeder is quickly found. The ratchet connected with it drives the component braid forward a distance through the connecting rod, and drive

Three methods of PCB circuit board heating

​PCB circuit board and FPC flexible circuit board hot pressing machine heating methods now mainly have steam, superhot water, hot oil three methods.

Chemical deburring process of the latest PCB circuit board

In addition, the process can prevent hydrogen embrittlement, because the process does not form a closed space, which helps to prevent acidic materials during plating from being trapped inside the workpiece, thus preventing hydrogen elements from entering

PCB circuit board price need to consider what factors?

pcb circuit board has a variety of production processes, such as gold-plated plate and tin plate, the production of shape gong (milling) board and beer (punching) board, the use of silk screen line and dry film line, different production process costs are

Nickel sulfate plating technology and troubleshooting of PCB circuit board

PCB (English Printed Circuie Board printed circuit board is short for) with nickel plating as the substrate coating of precious metals and base metals, for some single-sided printed boards, also commonly used as the surface layer.

PCB circuit boards throw copper common three main causes

ircuit board defect detection includes two parts: solder spot defect detection and component detection. The traditional detection adopts manual detection method, which is easy to miss detection, slow detection speed, long detection time and high cost, and

How to quickly repair the VCC short circuit fault in pcb circuit board

The number of holes should be reduced as far as possible. It should be known that a hole in the circuit board will bring about 10pF capacitance effect, which is a great interference in high-frequency circuits.

PCB circuit board factory to share the main causes of PCB board explosion and prevention countermeasures

Although baking is the best way to improve the burst board, baking not only wastes time, but also wastes equipment and manpower, and the Tg value will decrease after baking PCB is also a problem.

PCB circuit board layout design of the common seven questions seven answers

The internal network table is the network table used for wiring inside the PCB system after modification according to the imported external network table. Strictly speaking, these two types of network tables are completely different concepts, but the read
