Single-sided or Double-sided PCBs?

January 31, 2020
No Comments

Fundamentally, single-sided and double-sided printed circuit boards serve the same purpose. Both serve as catalysts for electrical connections between components, however there are some key differences that set them apart from each other. More specifically, they differ in the costs associated with production and development processes, as well as ampacity differences.

No Comments

Essential to the success of any printed circuit board (PCB) manufacturing project are the detailed notes included in the fabrication drawing. While the design files (typically Gerber or ODB++) contain the most basic structure and outline of the board design, it is the fabrication drawing that tells the manufacturer the specific details about a board that make it unique.

Gerber File Issues: Tips to Avoid Most Common Problems
