Is Silkscreen Position Number Necessary on PCB? Many Products Actually Do Not Have It!

Is it possible not to place silkscreen position numbers on a PCB? The silkscreen position number is mainly for convenience during manual soldering or prototype debugging stages, as it visually indicates the component positions, facilitating assembly, maintenance, and testing, primarily used in the prototype phase. It is indeed possible to manage without position numbers when … Read more

PCB Without Mark Points: The Critical SMT 'Lifeline' Engineers Must Be Aware Of

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

Routing Between Adjacent Pads of SMT Components

by
Routing Between Adjacent Pads of SMT Components

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

Comprehensive Guide to PCBA Electronic Production Process Based on FPC

[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
