Punch pins for electronic devices (carbide, SKH51, PCD)
For the press mold of electronic device circuit boards. Improved quality with high-precision punch pins.
In the electronics industry, particularly in circuit board manufacturing, precise drilling significantly affects product quality. As circuit boards become smaller and more densely packed, accurate drilling is essential to enhance component mounting precision and ensure product reliability. Low precision in punch pins can lead to misalignment of holes and the occurrence of burrs, resulting in product defects. Sanwa Creation's punch pins address these challenges by achieving high-precision drilling, thereby contributing to the improvement of electronic product quality. 【Application Scenarios】 - Press processing of circuit boards - Processing of connector components - Precision hole processing of electronic components 【Benefits of Implementation】 - Improved product quality through high-precision drilling - Cost reduction due to the longevity of punch pins - Increased design flexibility by accommodating various materials and shapes - Stable supply of quality products

Applications/Examples of results
We would like to introduce the "Punch Pin" handled by Sanwa Creation Co., Ltd. It is used for precision hole processing of inkjet printer heads, processing of carrier tapes that transport semiconductors and electronic components, nozzles for fuel injection systems, and stainless steel processing of connector parts. In addition, for press processing of ultra-thin materials such as copper foil and aluminum foil, using PCD (polycrystalline diamond) for the tip material reduces burning onto the punch and achieves a longer lifespan for the punch. 【Specifications (partial)】 ■ Material: carbide, SKH51, PCD (polycrystalline diamond), etc. ■ Standards: Custom-made to your desired size Shapes with multiple steps are also available. *For more details, please refer to the related links or feel free to contact us.
