In addition, pcb purchasers should pay attention to the point that when choosing pcb board manufacturers, they should not only choose from the perspective of price, but also compare the strength of pcb manufacturers, approximate product quotations, and se
Frame line as the basis of PCB circuit board contour processing, cutting processing can only be processed straight shape, special-shaped local available punch and milling machine processing.
The mechanical driving part is driven by the CAM spindle to drive the feeding mechanism, and the striking arm of the feeder is quickly found. The ratchet connected with it drives the component braid forward a distance through the connecting rod, and drive
PCB circuit board and FPC flexible circuit board hot pressing machine heating methods now mainly have steam, superhot water, hot oil three methods.
In addition, the process can prevent hydrogen embrittlement, because the process does not form a closed space, which helps to prevent acidic materials during plating from being trapped inside the workpiece, thus preventing hydrogen elements from entering
In the power supply circuit, the positive electrode of the electrolytic capacitor is connected to the output terminal of the power supply when the positive voltage is output, and the negative electrode is grounded.
pcb circuit board has a variety of production processes, such as gold-plated plate and tin plate, the production of shape gong (milling) board and beer (punching) board, the use of silk screen line and dry film line, different production process costs are
In high-speed PCB design, the serpentine line has no so-called filtering or anti-interference ability, which can only reduce the signal quality, so it is only used for timing matching and has no other purpose.
Layout is one of the most basic skills of PCB design engineer. The quality of the wiring will directly affect the performance of the whole system, most of the high-speed design theory will be finally realized and verified by Layout.
How much is the temperature resistance of pcb circuit board? How to test the heat resistance of pcb circuit board? These are the customers often consult questions, the following to give you a detailed answer.
A pass hole is a pad with an electroplating hole that connects copper wires on one PCB layer to another. High density multilayer circuit boards may use blind or buried holes, also known as micro through holes.
PCB (English Printed Circuie Board printed circuit board is short for) with nickel plating as the substrate coating of precious metals and base metals, for some single-sided printed boards, also commonly used as the surface layer.
