ELECTRONICS & SENSORS
Engineered for Signal Integrity. Built for Miniaturization.
Precision in electronic assemblies isn’t optional—it’s what separates clean signals from noise. When thin features distort, plating varies, or solder joints shift in reflow, small deviations turn into big failures.
At Gromax, DFM, tooling, stamping, and gaging sit under one roof. We engineer contacts, terminals, and shields for real conditions—controlling form, finish, and function from coined EMI shields to micro terminals—so parts run right through final build.
what we
BUILD
Engineered for signal integrity, dimensional precision, and EMI compliance.
Board-to-Board & Wire-to-Board Signal Terminals
Provide reliable low-level signal and low/medium current paths in connectors, headers, terminal blocks, and sensor modules.
RF/EMI Shield Cans & Frames
Reduce radiated/conducted emissions and susceptibility for radios, SoCs, PMICs, and sensitive analog front ends.
IC/Sensor Leadframes
Provide the mechanical die attach and electrical fan-out from silicon to the PCB in analog, MEMS, power, and mixed-signal packages.
Press-Fit / Compliant Pins & Blades
Solderless or mixed-tech interconnects into plated through-holes for rugged modules and serviceable assemblies.
Grounding & Antenna Spring Contacts
Create compliant chassis/RF grounds and low-profile antenna contacts in handhelds, wearables, and compact sensor nodes.
Connector Shells & Shield Cages
Provide mechanical robustness, EMI containment, and latching geometry for high-speed I/O and modular jacks.
Export Control
& Confidentiality Notice
To comply with ITAR, DFARS, and applicable U.S. export control regulations, Gromax does not display actual customer parts, drawings, specifications, or technical data in public-facing materials.

how we add
VALUE
Fine-Pitch Repeatability
±0.0015″ features, tight true-position, and SMT coplanarity control for 0.50–1.27 mm pitches on terminals and leadframes.
Signal & RF-Ready Surfaces
Selective Ni/Pd/Au, Ag, and Sn with controlled roughness and burr direction to cut fretting, contact resistance, and noise.
EMI/EMC Hardware That Fits
Coined, ultra-flat shields and frames with pick-and-place features, venting, and removable lids that stay planarity-true through reflow.
Press-Fit & SMT Integration
Compliant pins and blades tuned for insertion/retention, board-lock geometry, and reflow-stable springs for rugged, solderless or hybrid joints.
Mold/Overmold Ready Strips
Leadframes and contacts designed with downsets, tie-bar strategy, and carrier control for clean transfer into insert/transfer molds.
Quality You Can Prove
GR&R ≤10% on CTQs, inline vision and in-die sensing, plating microsections, and full PPAP/FAI traceability from first hit to shipment.
frequently asked
QUESTIONS
What materials are commonly used for electronics and sensor stampings?
Copper alloys are used for conductivity. Stainless is common for corrosion resistance and spring performance. Brass, beryllium copper, and nickel silver are also used depending on strength, formability, and contact requirements.
How tight can tolerances be held on stamped electronic components?
That depends on material thickness, feature size, forming, and flatness requirements. Tight tolerances are achievable, but repeatability across production is just as important as the print tolerance.
What should be reviewed before plating, soldering, or overmolding a stamped part?
Check base material, edge condition, plating thickness, solderability, and critical surfaces. For overmolding, review retention features, shutoffs, and stack-up early.
What should we look for in a stamping supplier for electronics and sensor parts?
Look at process capability, material experience, quality systems, tooling ownership, and ability to manage plating, tapping, and assembly.
How should we handle RoHS and REACH compliance?
Ask for material and plating declarations, compliance documentation, and clear support for restricted substance review.
What supply chain risks matter most today?
Common risks include single-source tooling, long-lead materials, weak change control, and limited visibility into sub-tier suppliers.
