After the delivery of a previous design project, due to an operational error by the on-site debugging personnel, the exposed wire ends touched the circuit board (which was coated with a conformal coating) when the rear panel of the device was opened, ultimately causing a short circuit. The feedback from the site indicated that the … Read more
In the design and manufacturing process of electronic devices, if a design is encountered where the circuit board ground is directly connected to the chassis ground, will this design cause problems? This article will explore this issue, hoping to provide assistance to our readers. 1. Electrical Safety Issues The direct connection may lead to a … Read more
In the process of developing and producing electronic products, one may encounter the scenario of needing to disassemble an existing PCB circuit board to analyze the circuit layout, component selection, and signal routing. Below, we will discuss an efficient process for disassembling a PCB circuit board, which we hope will be helpful to everyone. 1. … Read more
Core Competitiveness of Flexible Response and Fast Delivery「Click the blue text to follow us」2023 Flexible Circuit Boards (FPC) are circuit boards made from flexible substrates, characterized by their ability to bend, fold, and support three-dimensional wiring. Compared to traditional rigid circuit boards (PCBs), flexible circuit boards are widely used in modern electronic devices due to … Read more
