PCB Trace Corners Design Guide: Best Practices for Signal Integrity and Manufacturing
When an electronic device design finished it’s schematic drawing stage, next phase is to start PCB layout work. So, how to set-up the best track (routing) corners in PCB layout? Which is a better option, 45° corner or rounded corner? Can be layout as 90° corner?
How Temperature and Humidity Can Damage Your PCB
The circuit board is core component of any electronic device, and once it is corroded by moisture or high temperature, it will rise some quality headaches after PCB assembly process, such as moisture, blister, or layers de-lamination.
