Learn more →Exact manufacture to your released drawings, with change control on every revision.
Learn more →Send a sample or photos — we identify connectors, document the build and replicate it.
Learn more →Built for the teams that build hardware
Ten steps, no surprises
You see every stage — what we have, what we're waiting on, and what ships when.
Upload drawings or photos
Whatever documentation you have.
Engineering review
An engineer reads the spec and flags gaps.
Connector & material confirmation
Exact part numbers agreed before quoting.
DFM feedback
Manufacturability notes on your drawing.
Prototype
First articles with photos and measurements.
Customer approval
Nothing runs until you sign off the sample.
Production
Built to the approved article, rev-controlled.
Electrical & mechanical testing
Continuity, hi-pot, pull-force per plan.
Final inspection
Visual and dimensional check, records kept.
Worldwide shipping
Labeled, packed and tracked to your dock.
Engineering-first, not sales-first

Send what you have. We'll find what's missing.
Engineering drawings, cable drawings, pinouts, BOMs, connector specs, sample photos, reference images — any of it is a valid starting point.
If your documentation is incomplete, upload what you have. Our team will review it and identify the missing information.
Have a sample but no drawing?
Send us photos or a physical sample. We can identify connectors, document the assembly, create a prototype, and prepare the project for repeat production.
Sample → Identify → Document → Replicate
You get a drawing pack back — connector part numbers, wire spec, pinout — so the assembly is never undocumented again.
Re-sourcing an existing harness?
Tariffs, lead times, or single-supplier risk — we transfer running assemblies from your current vendor: same drawing, same connector part numbers, pilot lot checked side-by-side before cutover.
- 1Current drawings & golden samples in
- 2Gap & risk review against the print
- 3Pilot lot, checked side-by-side
- 4Cutover under revision control

Hardware startup"Documentation was the difference — every lot arrived with test records we could file straight into our QMS."
Medical device product teamCommon questions
Can you manufacture from a physical sample?
Yes. We reverse-document the sample — connectors, wire, pinout — and return a drawing pack for your approval before building.
Can you identify unknown connectors?
Usually from clear photos with a scale reference; always from a physical sample.
What files are required for a quote?
Ideally a drawing, pinout and BOM — but photos and a description are enough to start an engineering review.
Can you source connectors and terminals?
Yes — genuine JST, Molex, TE, Hirose and others through Shenzhen's supply chain, with brands confirmed in writing.
Do you support low-volume production?
Yes — small runs are a core service, not an exception.
What is the typical prototype lead time?
It depends on connector availability — we confirm a date with the quote rather than promise a blanket number.
What cable testing is available?
Continuity, electrical, hi-pot and pull-force testing, plus custom fixtures where the spec calls for them.
Which Incoterms do you ship under?
EXW, FOB Shenzhen / Hong Kong, or DDP to your dock — agreed on the quote, not after.
What are your payment terms?
T/T — typically a deposit with balance at shipment for new customers; NET terms for established repeat production.
Can you manufacture custom pinouts?
Yes — pinouts are confirmed in the drawing pack and verified by continuity testing.
Can you provide overmolding?
Yes, including custom tooling; we'll advise when a molded part justifies its tooling cost.
Can you support repeat production orders?
Yes — approved documentation is kept under revision control so reorders match the last approved article.
Can you use customer-specified connector brands?
Yes — specified brands are sourced as specified, never silently substituted.
How are engineering changes managed?
By written revision: change, cost and schedule impact confirmed before anything is built to the new rev.
Can you ship internationally?
Yes — worldwide by courier or freight, with export documentation handled.
Do you sign NDAs?
Yes — yours or ours, before any drawings change hands.
Who owns custom tooling, like overmold tools?
You do. Customer-paid tooling is customer property, documented in the quote, and never used for another customer.
What if parts arrive defective?
Report the nonconformance and we repair, replace or credit — handled with a documented corrective-action response, not a shrug.
