Thin-Gauge Lead Frames & Precision Stampings

Performance

PRECISION WHERE THIN GAUGE IS UNFORGIVING

In thin-gauge work the tolerance band and the burr band are the same band. Our tool room sets punch-to-die clearance per alloy, protects small punches with progressive pilot lockdown, and verifies punch wear by stroke count before edges degrade. In-line vision watches every stroke at press speed; the quality lab backs it with CMM and optical measurement. The result is a lead frame or contact array where feature-to-feature position comes from the die itself, part after part, across millions of strokes.

Thin gauge changes the physics of stamping. At 0.05-0.10 mm strip, punch buckling, burr ratio and springback dominate the cost curve: die clearances drop to 4-8 percent of material thickness, pilot registration has to hold pitch within a few thousandths at 300 strokes per minute, and the strip layout decides whether the part comes out flat or curled. That is why the die, not the press nameplate, is what you are really buying.

ISTAMPING runs twenty presses (25-80 ton, up to 300 SPM) with automated coil feeding on copper alloys, phosphor bronze, brass and stainless strip from 0.05 mm to 3.0 mm. Lead frames, terminal strips, contact arrays and EMI components are typical parts. Every program ships with first-article inspection against the drawing, SPC on critical features and PPAP documentation on request, under IATF 16949:2016.
