The PCB project generally contains four files: XXX.SchDoc(PCB schematic diagram), XXX.PcbDoc(PCB packing diagram), XXX.SchLib(PCB schematic diagram), XXX. The general process is as follows: first draw [PCB schematic library SchLib], then draw [PCB encapsulation library PcbLib], and associate the schematic library components with the encapsulation library. Then draw [PCB schematic diagram SchDoc], and update it to [...]
The Printedcircuitboard, or PCB for short, is a substrate for assembling electronic parts, and a printed board for connecting and printing components on the general base material according to the predetermined design. The main function of this product is to connect various electronic components to preset circuits, which ACTS as relay transmission and is the [...]
SMT is also known as surface mount technology. In the manufacturing process, solder paste is heated and melted under a kind of heating environment, so that PCB solder pad can be reliably combined with surface mount components by solder paste alloy. We call this process reflow soldering. When the circuit board passes Reflow (Reflow soldering), [...]
Printed circuit board international fair of Taiwan (TPCA), an annual event for printed circuit boards, kicked off yesterday (24). Wu yonghui, President of the Taiwan circuit board association and general manager of jialianyi, said that thanks to the emerging application technologies of 5G, AI artificial intelligence and vehicle, the PCB market is still hot in [...]
PCB industry is technology intensive and capital intensive, but it is still labor intensive. A large amount of automation equipment requires manual operation and assembly line work. A medium-sized PCB enterprise has thousands of employees. As the industrial transfer and upgrading, the implementation of the new labor contract law, the economic structure changes bring the [...]
PCBA industry is an industry with high degree of informatization in China at present. The general view in the industry is that ERP+MES+APS realizes enterprise informatization management. At present, large-scale enterprises have implemented ERP, and many enterprises have introduced MES system. APS is expected to be the next big import. Why do I need to [...]
