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.
3． Progressive Die Stamping Product Features & Advantage
|

Advantage to You |
|
Micron-Level Dimensional & Geometric Accuracy |
Achieve lead width and pitch tolerances within ±0.01mm, overall coplanarity ≤0.02mm, providing a perfect foundation for automated chip wire bonding. |
|
Ultra-Clean Production & Contamination Control |
Key production and cleaning processes are carried out in a controlled environment, with strict control over particulate matter, oil, and ion contamination to meet the stringent cleanliness requirements of the semiconductor industry. |
|
High-Density Multi-Lead Array Forming |
Capable of stably producing high-density lead frames with over 100 leads and lead pitches less than 0.4mm, supporting the development of advanced packaging technologies. |
|
Precision Selective Plating Technology |
Precisely plate precious metals like silver, palladium, or gold on designated areas of the frame (e.g., inner leads, outer leads), ensuring excellent solderability and bondability while controlling costs. |
|
Complete Material & Process Traceability |
Establish a full-process traceability system from the copper strip raw material batch to the final plating batch, and provide CPK data reports for critical dimensions, supporting your quality system. |

5. Progressive Die Stamping Product Application
Our products form the "skeleton" and "blood vessels" of integrated circuits:
Discrete device packaging: Lead frames for diodes, transistors, and power MOSFETs, requiring high current carrying capacity and excellent heat dissipation design.
Integrated circuit packaging | QFN (Quad Flat No-Lead), DFN, SOP, SOT series lead frames, etc., are the basic materials for mainstream chip packaging.
Power module packaging: Terminals and substrates for IGBT and SiC modules, requiring thick copper stamping and high current carrying capacity.
Optoelectronic device packaging | LED brackets, requiring high reflectivity surfaces and precise cup molding.
