In order to ensure the production quality of PCB board, the manufacturer has gone through a variety of detection methods in the production process, and each detection method will target at different PCB board defects.

The typical process of PCB multilayer circuit board processing is "graphic plating method". That is, a layer of lead-tin corrosion resistance layer is pre-plated on the copper foil part that needs to be preserved on the outer layer of the board, that is, the graphic part of the circuit, and then the other copper foil is corroded by chemical methods, which is called etching.

The PCB forms a connection between the point and the printed element according to a predetermined design on the general substrate. The main function of this product is to make various electronic components form a predetermined circuit connection, play the role of relay transmission, is the key electronic interconnection of electronic products, known as the "mother of electronic products".

Printed circuit boards are providers of electrical connections for electronic components. Its design is mainly layout design; The main advantage of using circuit boards is to greatly reduce wiring and assembly errors, improve the level of automation and production labor rate.

PCB wiring is very important in the entire pcb design, how to do fast and efficient wiring, and make your PCB wiring look tall, is worth studying. Sorted out the 7 aspects that need to be paid attention to in PCB wiring, come and check the gaps!

Today, I will take you to understand the surface process of PCB board, and compare the advantages and disadvantages of different PCB board surface treatment processes and applicable scenarios.

The most important and difficult to control point in electronic assembly is the reliability of soldering. Soldering is a special process, and its results cannot be verified by subsequent monitoring or measurement, and its quality problems will only appear after the product is delivered. reliability.

We would like to talk to you about the layout of ground wires in different layers of PCB boards, which will be of great help to you when laying out ground wires on different PCB boards.
