In microcontroller development, we often need to hand over the designed PCB files to the factory for production. Recently, one of our engineers encountered a troubling issue, as the PCB board lacked Mark points, resulting in deductions from the SMT factory. Today, we will discuss this topic: how important are Mark points in SMT processing? … Read more
For the layout of SMT components with small pin pitches such as QFP, QFN, and SOP, we sometimes encounter situations where adjacent pins of these components need to be interconnected. It has been observed that many designers, in an effort to save time, directly route the connection between the pads, effectively shorting the pins together. … 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, 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
The design differences of contact points have varying impacts on contact quality and reliability, accessibility, and subsequent solderability, which are negligible for small contact points. 1. Component Testing As the BGA pitch and solder ball size decrease, the design of socket manufacturers faces increasing challenges to adequately test BGA packages. Socket manufacturers are focusing on … Read more
