Recycle PCB components for other purposes
One of the important criteria for determining the requirements for recycling components is to know how to place components on the next board. One of the final standards is the type of component packaging required.
Several types of PCBA surface treatments
Lead and bromine are the hottest topics right now. Lead-free halogen will affect the development of PCB in many ways.
Why should PCB circuit board brush three anti paint
Three anti paint has satisfactory high and low temperature resistance; It cures into a transparent film that tries to protect the circuit from damage in such conditions as chemicals, shock, moisture, salt spray, moisture and high temperatures.
A brief introduction to the assembly and assembly process of PCB flip chip
As time goes by, the size of the high-performance chip increases, the number of Solder Bump increases, and the substrate becomes thinner and thinner. In order to improve the reliability of the product, it is necessary to fill the bottom.
Why can't PCB line walk 90 degree right Angle
For RF microwave signal transmission line, or preferred to walk the arc line, or even to walk the "45° external miter" line
Factors that affect PCB production price changes
PCB processing belongs to OEM customers OEM products, not the same customer customized products are different, so PCB processing there is a variable price.
Circuit and substrate flush PCB circuit board production process development
If the contact or line on the PCB circuit board needs to contact with the parts over and over again, with the passage of the product office hours, the appearance of the metal will reveal a certain wear, so the contact is not good.
Precautions in the production process of PCB circuit board proofing
PCB proofing refers to the trial production of PCB before mass production. After the electronic engineer presets the circuit and completes the PCB Layout, he carries out the process of small batch trial production to the factory, that is, PCB proofing.
Explain the process of PCB circuit board
Specific office process: incoming materials → inspection data → visual inspection → conforming to standards →FQA sampling → conforming to standards → packaging → not suitable for standards → disposal → investigation.
The principle and use of PCBA circuit board test stand
PCBA test stand is an indispensable test tool in SMT patch processing and production. It mainly tests the produced circuit board, and determines whether the board is a good product by the detected signals, pictures, sound temperature and so on.
