Causes and measures of plate bending and warping
Most of today's circuit boards are multi-layer boards, and there will be rivets between layers. The link points are divided into through holes, blind holes and buried holes. The place where there are link points will limit the effect of the board.
How to improve EMI of circuit board through component placement?
The EMI control of the printed circuit board becomes extremely important for the overall design. How to avoid PCB electromagnetic interference in switching power supply has become a topic that developers are very concerned about.
Analysis of the three main reasons for PCB copper dumping
Printed circuit board PCB copper wire off bad, PCB factories are said to be laminate problems, requiring its production factory to bear bad losses.
Solder paste quality process parameters
In solder paste printing, there is a certain restrictive relationship between the speed of the scraper, the pressure of the scraper, the Angle of the scraper and the mesh plate, the release speed and the viscosity of the solder paste.
Basic knowledge analysis of PCB schematic diagram
Circuit diagram, also known as circuit schematic diagram, is a kind of drawings reflecting the electrical connection of each component of electronic equipment. The circuit diagram consists of some abstract symbols, according to certain rules.
What are the common PCB defects
Modern PCBA electronic assembly is a complex process, in the process of production, due to PCB substrate, PCB board processing process factors lead to PCB defects.
Various sensors in the patch machine are introduced
The SMT machine is equipped with a variety of sensors. With the improvement of the intelligent degree of the SMT machine, the electrical performance of components can be checked and the normal operation of the machine can be monitored at all times.
What are the precautions for PCB proofing?
The closed physical border is a basic platform for future component layout and wiring, and also a constraint on automatic layout. Corner place best use arc, on the one hand can avoid sharp Angle scratch workers, but also can reduce the stress effect.
SMT patch processing knowledge
SMT processing plant plays an important role in the electronic processing industry, which is indispensable for the precision and miniaturization of electronic products
