As of 2025, automobiles are no longer just a combination of mechanics and steel; they are “mobile intelligent terminals” equipped with thousands of chips and hundreds of control boards. From BYD’s smart cockpit to XPeng’s autonomous driving systems, from Tesla’s battery management systems to Li Auto’s air suspension control, every performance enhancement relies on the … Read more
Solder joint processing in printed circuit board assembly (PCBA) is crucial, as the quality of solder joints directly affects the overall performance and reliability of the product. However, during actual production, issues with solder joint failure may arise. How can we reasonably address this problem? 1. Why Do Solder Joints Fail? ① Improper soldering process: … Read more
[PCB Information Network] FPC, also known as Flexible Printed Circuit, has a significantly different PCBA assembly and soldering process compared to rigid circuit boards. Due to the insufficient hardness and flexibility of FPC boards, without using dedicated carriers, it is impossible to complete basic SMT processes such as fixing, transmission, printing, and placement. 1. Pre-treatment … Read more
SMT Top Networking Circle A professional circle for sharing networking resources and achieving career advancement. New Platform 2020 1. FPC Preprocessing FPC boards are relatively soft and are generally not vacuum packaged when leaving the factory. They are prone to absorb moisture from the air during transportation and storage, so they need to undergo a … Read more
“ In the previous article (How to Control Common Impedance Interference on PCBA? – Reducing Common Impedance), we mainly discussed how to reduce interference from the perspective of lowering common impedance. However, in the design of PCBA, there are many limitations to reducing common impedance, such as the non-zero impedance characteristics of conductors. If we … Read more

SMT, short for Surface Mount Technology, originated in the 1960s, involves directly mounting SMD components onto PCBs. Its greatest advantage is the high wiring density per unit area of each component, which shortens connection lines and improves electrical performance. Below, I will quickly guide you through the SMT process flow. (This is SMT) 01 SMT … Read more
From slash-and-burn agriculture to mechanized production, every transformation in agriculture has profoundly impacted human civilization. Today, amidst the wave of digitalization and intelligence, agriculture is ushering in unprecedented opportunities for transformation. Sensors have replaced the experience of traditional farmers, algorithms have optimized millennia-old farming practices, and behind this is a series of precision electronic hardware … Read more
