High Precision Progressive Stamping Process For Electronic Components And Shields Mass Production
High-Precision Progressive Stamping for Thin-Gauge (0.05-1.2mm) Electronic Components & Shields Mass Production
1．Progressive Die Stamping Quick Detail
In the semiconductor and microelectronics packaging field, progressive die stamping is a core technology for manufacturing leadframes and precision connectors. We focus on this cutting-edge field and have the capability to perform micron-level precision machining on ultra-thin, highly conductive materials. We not only pursue extreme dimensional accuracy but also emphasize the integrity of the material's crystal structure, surface cleanliness, and the uniformity of the electroplated layer to ensure the final packaging yield and long-term reliability of the devices.
2. Progressive Die Stamping Product Description
We don't produce ordinary metal sheets, but rather the crucial carriers that support integrated circuit chips and enable their electrical connection to the outside world—lead frames. The width, spacing, and coplanarity of each lead directly affect the bonding quality and heat dissipation performance of the chip. We utilize ultra-high precision continuous die technology, combined with precise electroplating and etching post-processing, to produce various lead frames that meet stringent standards such as JEDEC, serving diverse needs from discrete devices to high-end QFN and DFN packages.
