Punch pins ideal for semiconductor lead frame processing. Achieves high precision and long lifespan.
In the semiconductor industry, the miniaturization and high density of products are advancing, leading to a demand for precision processing of lead frames. In particular, the accurate shape and dimensional precision of leads are critical factors that influence the performance and reliability of semiconductor devices. Low accuracy in punch pins can lead to deformation or breakage of leads, resulting in device defects. Sanwa Creation's punch pins are used in precision hole processing for inkjet printer heads, processing of carrier tapes that transport semiconductor and electronic components, fuel injection nozzle heads, and stainless steel processing of connector parts. 【Application Scenes】 - Press processing of semiconductor lead frames - Processing of carrier tapes - Processing of connector parts 【Effects of Implementation】 - Improved yield through high-precision lead frame processing - Increased longevity of punches by adopting PCD (polycrystalline diamond) - Enhanced design flexibility by accommodating various shapes
