    Countersink PCB: The Ultimate FAQ Guide

    Are you worried about drill holes on the PCB surface?

    Countersinking superbly handles this issue. Countersink PCB develops the use of PCB drill holes and screws. Its superior features and immense positive sides improve the functionality of PCB applications.

    PCBMay is the perfect option for countersink PCB requirements. Here, we are going to explain the pros and cons of this circuit board with proper detailing. We hope this FAQ guide will enrich you with PCB countersink holes. Let’s make a move.

    What Is A Countersink PCB?

    Countersink PCB holes are conical-shaped drilled holes cut to the PCB laminate. These holes are used in allowing the utilization of fasteners and flat head screws. Countersink holes usually act to sit screw heads on the lower or upper part of the printed circuit board.

    It improves the appearance of the circuit boards. There are different hole angles in PCB countersinking. So, it has versatile applications in the electronics sector. Its symbol looks like the English letter “V”. It does not allow drilling straight to the PCB materials.

    PCB Countersink Hole

    PCB Countersink Hole

    The depth of these holes varies due to some reasons. Deep PCB holes ensure easier covering of the flatheads through the plugs. Again, its holding strength is enough to promote the effectiveness of electronic gadgets that have space restraints.

    What Is The Difference Between A Counterbore And Countersink In A PCB?

    Countersink and counterbore are two types of drilled hole cutting on the PCB laminate. Though these holes have multiple similarities, they also consist of distinguishing properties. Now, we are here to clear your concept about these two PCB drilled hole types.

    Hole Shape

    The typical shape of a countersink hole is conical. That’s why its symbol is “V”. In contrast, PCB counterbore holes are cylindrical, and their symbol is “T”

    Hole Angles

    PCB countersink holes have a wide-scale of hole angles. Its typical angles are 82⁰, 90⁰, and 100⁰. Besides, 60⁰, 110⁰, 120⁰, etc angles are also available in the countersinking mechanism.

    On the contrary, counterbore holes have a limited angle. Its hole angle is only vertical 0⁰.


    Countersink holes are highly effective for high-density PCB applications. Such as mobile phones, laptops, and other wearable electronic appliances. Countersinking makes the component’s placement easier due to the ability to make additional space on the PCB laminate.

    But, counterbore that makes flat-bottomed holes are used in washers and various 6-headed screws and caps.

    Space Management

    Countersink provides a better facility in space management on the PCB laminate compared to counterbore holes. Its secure and tight fittings allow the PCB manufacturer to arrange the components properly.


    Countersink holes render a smooth PCB surface. Besides, these drilled holes don’t cause any interference during the PCB design. But, counterbore holes are not suitable for having an impressive outlooking of the PCB laminate.

    Countersink Vs Counterbore Holes On a PCB


    Dimensioning refers to hole size, surface types, materials, etc. Unlike counterbore holes, the angular sides lie in the corner portion in the case of countersink holes.

    The required dimensions of PCB countersink holes are angles, surface diameter, depth of counter drill holes, etc.

    On the other hand, diameter, corner radius, depth, etc are dimensions of PCB counterbore holes.


    Counterbore holes have a high holding strength because of their shape. Here, the applied force impacts the parallel segment of the screw hole axis. But, the force gets dispersed due to the conical shape in the case of countersink holes.

    That’s why countersink PCB holes have comparatively lesser holding strength. But, these holes can deliver sufficient strength that is required for a top-class printed circuit board.

    Now, it is clear that countersink PCBs are more advanced than counterbore holes in many aspects.
