High Density PCB Circuit Board Technology and ApplicationHigh-density circuit board technology is a key technology in the field of modern circuit board design and manufacturing. It enables more circuit components to be integrated on the circuit board by i
Aluminum substrate PCB circuit board Introduce the advantages and disadvantages of ceramic PCB circuit boards. One of the disadvantages is that the ceramic substrate is too expensive and fragile. Ordinary glass fiber PCBs have poor heat dissipation, ce
PCB circuit board assembly processCircuit boards are found in just about every electronic device you use, and while they're common, that doesn't mean they're simple. Producing circuit boards by SMT is a complex business, and proper assembly requires the r
The current market situation of automotive electronics PCBA is that the pre-installation market is matched by the vehicle market itself, and the suppliers are generally subsidiaries or holding companies of their own companies.
With the rise of the electronic industry, circuit board production and development has become a more and more important part of PCB proofing a circuit board is not simple, easy to say.
At present, for PCB curing, the most suitable use or UV light source, because UV light source has the characteristics of other mercury lamps do not have, just take the light source, UV light source is a cold light source, the curing principle is that the
to see what is the surface treatment process, we commonly have: spray lead tin (hot air leveling), OSP(environmental protection board), spray pure tin, tin, silver, gold and so on, of course, the surface process is different, the price will be different.
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.
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
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
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.
