CHALLENGES WE SOLVE
Electronics Stamping Challenges & Our Solutions
Four recurring electronics failure modes seen in incoming RFQs — and how each is prevented on our line.
01
Lead frames
The Challenge
Progressive-die wear drifts fine-pitch features out of coplanarity before you see it.
Our Solution
Pitch and coplanarity trended against die-wear compensation and sampled on optical measurement.
02
EMI/RFI shields
The Challenge
Incomplete shield form recovery breaks grounding continuity and lets EMI escape spec.
Our Solution
Form recovery and ground-contact faces verified by CMM first article plus in-line vision.
03
Connectors & pins
The Challenge
Contact-resistance drift from tolerance creep on terminal features causes intermittent failures in the field.
Our Solution
Held with 100% critical-dimension checks at press speed and plating-thickness verification per lot.
04
Sensor components
The Challenge
Loss of spring force after plating or heat exposure silently degrades the whole connection.
Our Solution
Post-process form checks keep spring dimensions inside the drawing window lot after lot.

APPLICATION & INDUSTRY SOLUTIONS
Metal Stampings for Electronics
Lead frames
Fine-pitch lead frames stamped to 0.005 mm precision for IC packaging - with controlled plating and clean, burr-free edges.
EMI/RFI shields
Board-level EMI shields stamped from nickel silver, stainless steel or tin-plated steel - with solderable attachment options.
Connectors & pins
Precision stamped connectors, pins and press-fit terminals for electronic assemblies - tight tolerances for reliable insertion.

Precision Stamped Components for Consumer and Industrial Electronics
The electronics parts on our presses right now: fine-pitch lead frames, board-level EMI/RFI shield cans and frames, press-fit pins, battery contacts and sensor springs for IoT devices, smart-home hardware and wearables. Feature sizes sit in the sub-millimeter band, so the work is carried on fine-pitch progressive dies with ±0.005 mm positioning and burr-free shearing — parts that go straight onto SMT and wave-solder lines without secondary cleaning.
- 0.005 mm precision for fine-pitch and miniature features
- Managed plating - selective gold, tin and nickel options
- Clean, burr-free edges for reliable downstream assembly
- High-speed production for consumer electronics volumes
Electronics stamping
Miniature Precision Stamping for Electronics
Miniature stamped parts such as lead frames, EMI shielding cans, and connector pins demand dimensional consistency measured in microns - a single out-of-tolerance feature can stall automated SMT assembly. Our stamping engineers control material springback through compensated die geometry and carefully selected alloys from 0.05 to 3.0 mm, while high-speed presses running up to 300 SPM hold ±0.005 mm positioning accuracy across millions of strokes. CMM and inline vision verification keep every batch repeatable, so high-volume, high-cadence micro-stamping runs deliver the same tight tolerances from the first part to the last.
- high-speed presses up to 300 SPM hold ±0.005 mm positioning accuracy for fine-pitch lead frames, shielding cans, and connector pins
- Springback-compensated progressive die design keeps thin-gauge parts (from 0.10 mm) flat and dimensionally stable across million-stroke runs
- Reel-to-reel selective plating applies conductive finishes only where required, protecting critical contact surfaces and solder joints on miniature parts
- CMM measurement plus inline vision inspection verify critical dimensions on every batch, supporting lot-to-lot consistency under IATF 16949:2016 quality management

DFM & ENGINEERING SUPPORT
Design for Manufacturability for Electronics
We review material, tolerance, bend and volume economics before tooling starts.
What We Review
Lead frames geometry
Fine-pitch geometry — die-wear compensation, coplanarity target, and pack-out on the reel.
EMI/RFI shields geometry
Shield enclosure — form recovery after forming, ground-contact faces, and aperture tolerance over the protected circuit.
Connectors & pins geometry
Contact geometry — mating tolerance, plating thickness for conductivity, and reel-feed orientation for in-line inspection.
Sensor components geometry
Feature walk-through — material formability, bend radii, tolerance stack-up and plating compatibility for this part.
What Our DFM Review Checks
Bend radii
Inside radius held at R≥1.0t on spring tempers; tighter bends flagged for anneal or grade change before die design starts.
Holes & cutouts
Hole diameter ≥0.8t, pushed to 0.6t only with hardened punch steel; thin-gauge cutouts checked for tear-out.
Burr & edge quality
Burr height held under 0.05 mm so parts mate flat in assembly and plating adheres at the edges.
Tolerance & plating impact
Critical features piloted to ±0.005 mm; plating thickness (gold 2-8 µm, tin/zinc 5-12 µm) compensated in die design.
