Excellent soldering quality provides good stability and reliability for circuits, while poor soldering methods can lead to component damage, significant testing difficulties, and potential hazards that prevent devices from functioning … Read more
Click the blue text to follow us In the PCBA processing workshop, every completed surface-mounted circuit board with program control must undergo a “digital enlightenment”—program burning. We understand that this step directly determines the functionality and market performance of electronic products.1. The Essence of Burning: The Fusion Hub of Hardware and SoftwareBurning is not merely … Read more
A certain audio product’s PCBA (wave soldering process) experienced burning during use. The failure rate was high when using Flux A, slightly decreased after cleaning, and dropped to zero after switching to Flux B. This article will explore the failure reasons through a series of professional testing and analysis methods. 1. Visual Analysis From visual … Read more
Click the blue text Follow us In the wave of Industry 4.0, the electronic manufacturing industry is undergoing a profound transformation from “mass production” to “customized production.” The multi-variety small-batch PCBA production model, with its advantage of flexibly responding to market demands, is gradually becoming the standard in fields such as consumer electronics, industrial control, … Read more
Recently, the project I am responsible for has started mass production, with the first batch planned to produce two hundred sets. During the production testing phase, it was found that seven PCBA boards had issues, with symptoms including: the boards not powering on, no signal on the acquisition channels, and programs unable to download…Upon hearing … Read more
Every day, the first thing I do when I wake up is browse Xianyu; I don’t even bother opening Taobao. Xianyu always surprises me with something new. While browsing, I discovered a great tool that can quickly locate short circuit positions on circuit boards.The rosin vaporizer family includes a brush, vaporizer, charging cable, instruction manual, … Read more
In the field of microelectronics manufacturing, the cleanliness of PCB cleanrooms directly determines product yield. As the core system maintaining the workshop environment, the air circulation system is responsible for filtering particulate matter, controlling temperature and humidity, and balancing pressure differentials. However, traditional designs often face challenges such as high energy consumption, airflow dead zones, … Read more
