1. Character placement is unreasonable The character cover pad SMD soldering piece brings great inconvenience to the soldering of the component and the on-off test of the printed board. The character design is too small, which makes screen printing difficult, and the over-construction causes characters to be stacked on each other, making it difficult to distinguish. 2. the processing ind...
PCBA board needs to be electrical and functional tested before delivery to customer. The normal methods include FCT (function test) and ICT (in circuit test). Few decades ago, ICT was popular in electronic manufacturing industry. Many big digital product companies (such as mobile) took ICT to test almost every single component on board, in order to verify if it complies with design range and param...
The day before yesterday evening , one of my friends was chatting with me, who worked in the electronics world. And suddenly, he asked me, “Do you ever think why are circuit boards green?” I was so spellbound that I couldn’t answer it immediately. I just thought that he asked it out of curiosity, and may be he was mistaken to assume that all circuit boards are green. So, when I was free from...
What is a Printed Circuit Board (PCB)? How is it done? What Does It Do? A PCB is not just a structure designed to keep electronic components fixed and anchored. Its functionalities are deeper and embrace several criteria. An interesting journey to discover printed circuits. PCB design: introduction The designers of 40 years ago were real heroes. They did not have computers...
