What are the production precautions for PCB half hole boards

Aug 29,2025

PCB half hole board is a special form of PCB that is often used in the design of high-density electronic products. Its characteristic is to leave a portion of metal material on the surface of the PCB for inserting terminals or other electronic components. Hubei Chucang Electronics Co., Ltd. introduces the production process of PCB half hole boards, which should pay attention to the following points:
First, prepare the printed circuit board and corresponding printing materials, such as copper foil board, photosensitive adhesive, etc. Then, the circuit pattern is transferred onto a photosensitive adhesive using UV exposure technology, and unwanted parts are peeled off using chemical or mechanical methods. Next, to make a half hole board, a special metal plate, such as gold plating, needs to be added to the photosensitive adhesive to prevent the metal left on the surface of the circuit board from being corroded.
After adding special metal plates, the circuit board will be sprayed with a protective coating to prevent damage during the PCB peeling and riveting stages. Then, a fine CNC machine is used to cut off the metal material on the surface, thus forming a half hole plate. During this process, special attention should be paid to the depth and accuracy of the cutting, ensuring that the area being cut has the correct shape and size to accommodate the installation of other electronic components.
Another key issue in producing PCB half hole boards is to avoid structural damage during heat dissipation design and cutting processes. Due to the fragile structure of the half hole plate, caution must be taken during its production process. On the premise of ensuring quality, structural damage can be avoided by increasing material thickness or structural reinforcement.
Producing high-quality PCB half hole boards requires the use of high-precision equipment and good materials. It should be noted that the production of PCB half hole boards may require selecting suitable materials from samples and testing and evaluating the materials. Overall, the production of PCB half hole boards requires careful design and a well-designed manufacturing process. Especially in the metal coating and cutting process on the surface of the circuit board, special care needs to be taken to ensure that the half hole board meets the requirements.
