What is a 6 layers PCB | YS - News - Printed Circuit boards manufacturer, HDI, Heavy copper

China two layer Fr4 PCB is one of the most popular types of PCBs because they make manufacturers to fabricate more complex circuits, which can benefit uses in higher technology applications and electronics. There is an abundance of applications and electronics which double sided PCBs can be used in electronics such as:LED lighting systems、Consumer Electronics.

What is the difference between a Countersink and a Counterbore?
