Before the advent of PCBs, circuits were made through point-to-point wiring. This method had low reliability, as aging circuits could lead to wire breakage, resulting in open or short circuits at connection points. Wire winding technology was a significant advancement in circuit technology, enhancing the durability and replaceability of wires by winding small diameter wires … Read more

In order to adapt to the rapid update of electronic products, product design engineers tend to choose AC/DC adapters that are easy to procure in the market and directly install multiple DC power supplies on the system’s circuit board. Since the electromagnetic interference generated by switching power supplies can affect the normal operation of electronic … Read more
Although PCB manufacturing online has become very quick and cheap, with some manufacturers even offering free test board production, compared to making a test circuit board in “one minute“, sending out for board production still takes too long. For circuits that need testing, quick prototyping allows for rapid iteration to complete experimental circuits. The final … Read more
PCB (Printed Circuit Board) is an important component of electronic devices. The main function is to provide mechanical support and electrical connections for components. 01 The Inventor of PCB The creator of the printed circuit board is Austrian Paul Eisler. In 1936, he first used printed circuit boards in radios. (Baidu Encyclopedia) (From Wikipedia) Before … Read more
The packaging substrate provides electrical connections, protection, support, heat dissipation, assembly, and other functions for chips and electronic components, achieving multi-pin integration, reducing the size of packaging products, improving electrical performance and heat dissipation, enabling ultra-high density or multi-chip modularization, and ensuring high reliability of electronic substrates. The packaging substrate can be simply understood as … Read more
