There are many types of ceramic products in the circuit board factory. It is said that there are more than 30 manufacturing processes, such as dry pressing, grouting, extrusion, injection, casting and isostatic pressing, etc.
Read MoreOSP, HASL, Emmersion gold, tin, silver, hard gold plated, gold plated, gold finger, nickel palladium OSP: cost lower, solderability is good, storage conditions are harsh, time is short, environmental protection technology, welding is good, smooth.
Read MoreWe often find that there are errors in some rules or principles that we take for granted. Electronic engineers also have such examples in circuit design. Here are eight misconceptions summarized by an engineer.
Read MoreCareful partners can easily find that the right angle of the original design is 90 degrees. When the board comes back, it turns into a R angle, which directly affects the accuracy of the shape. When it is serious, it will cause the device's position.
Read MoreThe surface finishing methods used in PCB board proofing are different. Each surface finishing method has its unique characteristics.
Read MoreFor a newly designed circuit board, it is often difficult to debug, especially when the board is large and the components are relatively large. But if we master a reasonable set of debugging methods, we will get twice the result with half the effort.
Read MoreWe have introduced several testing process and methods that was used in PCB manufacturing before like: Automatic Optical Inspection, Microsection testing, Measurement and functional test, today we will discuss a kind of testing machine and way.
Read MoreAdvanced PCB proofing: circuit board layout and system test The basic principles of high-speed PCB circuit board layout are as follows:
Read MoreIn PCB design, whether to use chip beads or chip inductors is mainly focused on application scenarios. PCB design printed circuit board design is based on the circuit schematic diagram to achieve the functions required by the circuit designer
