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.

PCBA foundry _ circuit board components

Circuit board composition: 1, welding plate: 2, layer number: 3, hole: 4, components: 5, wiring: 6, silk screen: 7, welding resistance layer: 8, positioning hole: 9, filling: 10, electrical boundary:

What is HDI and what is HDI circuit board?

Printed circuit boards are not common terminal products, because the definition of the name is a little disorderly.

Several characteristics of microwave RF circuit board design

In concept, wireless transmitter and receiver can be divided into two parts: fundamental frequency and radio frequency. Includes the frequency scale of the input signal of the transmitter and the frequency scale of the output signal of the receiver.

The difference between HDI circuit board and ordinary PCB circuit board

PCB board is a closed electronic device, is the electronic component of the support body, is the electronic component of the electrical joint carrier. HDI board is a high density interconnected circuit board.

Discussion on the new process of single hole plating on HDI circuit board

High density interconnection (HDI) circuit board technology can provide a higher density of circuit wiring, can make the end product preset more small scale.

Explain the manufacturing process of 8-layer circuit board

To form the pad, the solder shield (insulating layer) forming process is required, as well as to protect the copper foil and provide better insulation.

Distinguish circuit board quality is good or bad 2 ways

Integrated circuit board manufacturing process: 1, the drawn circuit board is printed out with transfer paper 2, cut the copperplate with sensitive plate to make the circuit board diagram of the whole process 3, with fine sandpaper to the surface of the c

Recycling technology of epoxy resin in waste printed circuit boards

At present, the technology of metal extraction and recycling in waste printed circuit boards has been relatively mature. However, there is the problem of recycling the large amount of metal that remains after extraction.

Explain the process of PCB circuit board manufacturing and packaging

Not paying attention to the packaging of products can bring immeasurable benefits.
