Understand the difference and function of PCB welding aid layer and welding resistance layer
In the process of PCB high-speed signal circuit design and wiring, engineers need to shorten the lead between the pins of high-speed circuit devices as much as possible.
5G drive PCB volume and price rise
In the future, with the emergence of new demands for automotive electronics, data centers and artificial intelligence, PCB industry will usher in new growth points.
Uv laser processing applications in PCB industry
Each circuit layer in the multilayer circuit board is pressed together by the action of semi-cured sheet; Depending on the circuit design, some areas of the semi-cured sheet need to be cut and then pressed together.
Eight kinds of PCB surface treatment technology
the environmental problems involved in PCB production are particularly prominent. The topic of lead and bromine is the hottest, lead-free and halogen-free will affect the development of PCB in many ways.
Review according to the "PCB checklist
Therefore, careful consideration should be given to the placement of ground wires in the layout. Mixing all kinds of ground will cause unstable power supply. The following points should be noted in the design of ground wire:
How to avoid PCB Electromagnetic Interference in Switching Power Supply Design
Take the core component of each functional circuit as the center, and carry out the layout around it. The components should be arranged evenly, neatly and compact on the PCB, and the leads and connections between the components should be reduced and short
About PCB high frequency circuit board wiring tips
The parameters of PCB board layer, the distance between signal wires, the electrical characteristics of the driver and receiver end, and the connection mode of signal wires all have a certain influence on the crosstalk.
High reliability PCB's 14 important characteristics
All of these problems can cause the solder shield to detach from the circuit board and eventually lead to corrosion of the copper circuit. Poor insulation characteristics can cause short circuits due to unexpected electrical connectivity/arcing.
PCB common three drill details
Defective sheeting requires special assembly procedures. If the end-of-life unit board (x-out) is not clearly marked, or it is not isolated from the sheeting, the known defective board may be assembled, wasting parts and time.
Rf circuit PCB design
According to experience, the effect of RF circuit not only depends on the performance of the RF circuit board itself, but also depends on the interaction with the CPU processing board.
PCB design of the core problem solution
these problems can be avoided. Because the design of the circuit board will vary according to different equipment, different use locations, different heat dissipation requirements, and different electromagnetic interference (EMI) situation, then the desig
