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...

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.

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...
