Counersink PCB Board
On countersink hole PCB board, there is a conical hole which is cut to allow the flat head screw to be used is called a countersink hole. It can also be called as a conical hole that is cut into a PCB FR4 laminate, or a hole created by using a drill. Countersink holes can be plated or non plated.
Countersink Hole is used on a PCB board that sink the screw head into PCB laminate.so that the board looks clean and flat. For countersink hole, generally speaking, it come into two types of shapes.V figure Count-sink and T figure Count-Sink.
A countersink hole in a PCB creates room for a clean installation and is ideal for tight-fitting applications in very delicate devices. PCB countersink applications found in mobile phones, small wearable devices and
IoT products.
If you have any countersink PCB requirements, contact our sales team and we are very pleased to provide you any PCB services that you need.
To make the countersink holes exactly that you want, we will need the following information.
• Angle of the hole
• Major Diameter (finished diameter of the hole at the surface)
• Depth the countersink is to be drilled
• Countersink hole is requried on the top or bottom side.
• The finished diameter of the shaft of the hole
• NPTH or PTH of the countersink hole.
• Tolerance is +/-0.15mm

Rohs Compliant
RoHS stands for Restriction of Hazardous Substances which is widely known as RoHS 1 (Directive 2002/95/EC), RoHS 2 (Directive 2011/65/EU), and RoHS 3 (Directive 2015/863), originating in the European Union. RoHS directive restricts the use of specific hazardous materials commonly found in Electrical and Electronic Products (EEE).
At Linked Electronics, we know how important the enviroment is to us and how important the health of our staff is. All the PCBs that we manufactured is complying with environmental and human health protection laws and regulations. All the Printed Circuit Boards or assembly PCB boards are complied with the reach and rohs regulations.
