I am laying out pcb and I want to confirm about the over drill size for a pin. The pin is 0.05". I forgot what is the conventional over size drill. Is it 0.06"? Or 0.065 to be safe?
Thanks
Alan

A PCB (printed circuit board) drill hole is a hole that is drilled into a PCB to create a connection between different layers of the board. It is typically used for inserting components or creating vias for electrical connections.
PCB drill holes are created using a drill bit that is specifically designed for drilling through the materials used in PCBs, such as fiberglass and copper. The drill bit is attached to a drilling machine that is programmed to create the holes at specific locations and sizes.
The size of a PCB drill hole can vary depending on the specific application and the manufacturer's specifications. However, the most commonly used sizes range from 0.2mm to 0.8mm in diameter.
Yes, PCB drill holes can be drilled at any angle, as long as the drilling machine is capable of rotating the drill bit to the desired angle. This is often necessary for creating vias that connect different layers of the PCB at non-perpendicular angles.
Yes, there are a few special considerations when it comes to PCB drill holes. These include the type and thickness of the material being drilled, the size and angle of the holes, and the precision required for the specific application. It is important to carefully plan and design the drill holes to ensure successful PCB production.
