The Significance and Design Difficulties of PCB Copper Coating
The significance of copper coating is to reduce the ground impedance and improve the anti-interference ability. Reduce voltage drop, improve power efficiency.
Cause analysis of excessive chloride ion consumption in PCB copper plating
At present, with the development of printed circuit boards in the direction of high density and high precision, more stringent requirements have been put forward for copper sulfate plating process.
Information technology: Grasp the new opportunity of PCB copper-clad plate
The negative film is used for direct etching, and the corrosion resistance left after development is a circuit, which is etched directly with acid etching solution.
Do you know the three reasons why PCB copper flakes fall off?
When the production of laminate using copper foil and the resin system does not match, resulting in sheet metal foil peeling strength is not enough, plug-in will also appear bad copper wire shedding.
Dry goods PCB copper must pay attention to, otherwise do not cover copper!
The grounding isolation belt near the crystal oscillator must be well grounded. In a word: the copper coating on PCB, if the grounding problem is handled well, is certainly "more advantages than disadvantages", it can reduce the signal line back...
PCB copper coating should pay attention to those problems? How to choose solid copper and grid copper?
the copper coating on PCB, if the grounding problem is handled well, is certainly "more advantages than disadvantages", it can reduce the signal line backflow area, reduce the signal external electromagnetic interference.
Does PCB copper coating do more good than harm?
Copper coating on PCB, if the grounding problem is handled well, is "more advantages than disadvantages", it can reduce the signal line backflow area, reduce the signal external electromagnetic interference.
PCB copper foil supply after chip shortage
A persistent semiconductor shortage is rapidly snowballing into a full-blown component shortage, underscoring the fragility of the current supply chain.
Analysis of the three main reasons for PCB copper dumping
Printed circuit board PCB copper wire off bad, PCB factories are said to be laminate problems, requiring its production factory to bear bad losses.
SMT manufacturer PCB surface to find the reason of PCB coppered laminate
According to the activity of flux, it can be divided into active (RA), medium active (RMA), inactive (R), water washing (OA), no cleaning (NC)
