by Bert Simonovich

May 2nd, 2024
10:00 am to 11:00 am PT

YouTuber and PCB designer Robert Feranec came to visit Sierra Circuits to learn more about our PCB manufacturing and assembly services. As he says in the video, “When you are designing boards, I think it is very useful to know some information about PCB manufacturing.”

Amit Bahl, Sierra’s director of sales and marketing, invited Robert Feranec to show him around and explain to him our manufacturing and assembling process from beginning to end. He was really amazed by several of our techniques, including the drilling part. He learned that layers of PCB can move and shrink, how to get a better value PCB, and many other tips.
