Wire-to-Board / PCB-Header Cordsets: OEM-Spec Assembly.
The wire side of your PCB header — JST PH/XH/GH, Molex KK/PicoBlade and 1.0 to 2.54 mm pitch cordsets built on the Cavite floor with UFLPA input-traceability support; Philippine origin, Section 301-free for product that qualifies as Philippine origin (standard US import duties may still apply, as determined by your customs broker), and IPC/WHMA-A-620 Class 3 acceptance by default. Send the header part number or drawing and we will reply with unit price, lead time, and a sample plan inside 12 hours.
Buyer Reality
Where Most pcb header connector Programs Slip.
Issue #01
Crimp height off spec — terminal backs out of the housing
A crimp height a few hundredths off the applicator spec gives a joint that passes visual but fails pull-force and backs out of the JST/Molex housing at vibration. We set crimp height per the terminal applicator sheet and pull-test to the IPC/WHMA-A-620 §19 minimum for the wire gauge, not by eye.
Issue #02
Wire gauge outside the terminal crimp range
A 24 AWG wire crimped into a terminal rated 28-30 AWG (or vice versa) never forms a gas-tight joint. We check the wire gauge against the terminal crimp range on every drawing and flag the mismatch back to engineering before build — the same catch that prevents field dropouts.
Issue #03
Reversed or unkeyed housing plugged backward
A non-keyed 2.54 mm header cordset inserted backward shorts VCC to GND on first power-up. Our build adds the polarity/keying per the housing part number and a colored pull tab so the operator and field tech see orientation in one glance.
Issue #04
Tin vs. gold plating wrong for the mating-cycle count
Tin-plated header terminals fret and lose contact after repeated mating; gold is needed for high-cycle or low-current signal. We call out tin vs. gold plating to the mating-cycle and current requirement rather than defaulting to tin.
Issue #05
Pitch confusion between 2.0 mm and 2.54 mm families
2.0 mm (e.g. Molex Milli-Grid) and 2.54 mm (0.1 in) headers look similar but do not intermate; the wrong housing will not seat on the PCB header. We bind the exact series and pitch to the header part number on the build instruction.
What We Build
The Capability Stack Behind The Build.
Crimp height and pull-force to applicator spec
Terminals are crimped on the correct JST/Molex applicator to the sheet crimp height and pull-tested to the IPC/WHMA-A-620 minimum for the wire gauge; crimp height is logged per lot.
Crimp cross-section verification
First-article crimps are cross-sectioned and checked for compaction, brush height, and no cut strands per IPC/WHMA-A-620 §19 before the run releases.
Contact retention and polarization audit
Contact retention in the housing is verified, and the keying/polarization is bound to the header part number so the cordset only seats one way.
Tin or gold plating to the cycle / current spec
Terminal plating (tin or gold, to thickness) is selected per mating-cycle and current requirement, and incoming plating is gated at goods-in.
100% continuity and HiPot
Every wire-to-board cordset runs 100% continuity and, where insulation rating requires, HiPot on a Cirris tester before pack-out.
Crimp validation per IPC/WHMA-A-620 §19 with cross-section on first article
ISO 9001 quality-system practices and IPC/WHMA-A-620 operator workmanship; ISO 9001 and IATF 16949 certificates held by Hebei Cloom
Cirris CR/CH 100% continuity
