Click Blue Text Follow us~ Today, I share an experience summary on PCB process design, hoping to inspire industry colleagues. 1 PCB Basic Technology 1.1 PCB Size and Shape The welding processing dimensions of the PCB material shape are width (200mm～250mm) * length (250mm～300mm). For PCBs with a long edge less than 125mm or a … Read more
Whether engineers or PCB manufacturers, they inevitably encounter PCB failures. The occurrence of these failures may lead to delays in product delivery, damage to the manufacturer’s reputation, and increased time and monetary costs. (Most importantly, it costs money.) Today, we mainly discuss PCB failure modes and solutions. (It is recommended to save for later viewing, … Read more
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
01 PCB Size [Background Explanation] The size of the PCB is limited by the capabilities of the electronic processing production line equipment. Therefore, suitable PCB sizes should be considered during product system design. (1) The maximum PCB size that SMT equipment can mount originates from the standard size of PCB materials, most of which are … 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
