Precision Quotation
& Engineering Service.

Quotation, DFM review, engineering-drawing intake, low-volume rush production, obsolete-component replacement, production-ready validation. The infrastructure that sits behind every cable assembly and wire harness program — converting customer drawings (EPLAN P8, Altium, AutoCAD Electrical, Solidworks Electrical, STEP, DXF, annotated PDF, photo, hand-sketch) into a validated build sheet within 4 business hours, and producing rush prototypes from 1 unit to 100 units inside 48-96 hours with the same workmanship as volume production.

PAIN-0101

DFM review takes 2 weeks

Most contract manufacturers turn DFM review in 2-3 weeks — kills the engineering iteration cycle, customer commits prematurely to a sub-optimal design.

PAIN-0202

Rush prototype priced at 10× volume

Single-unit prototypes priced at 10× volume rate at most shops — engineering teams ration prototype builds, validate fewer revisions, ship later with more risk.

PAIN-0303

Obsolete part on the BOM not flagged

Supplier accepts the customer BOM as-is, sources what it can, and discovers mid-production that one connector is now last-time-buy — program stalls while replacement gets evaluated.

PAIN-0404

Photo / sketch intake rejected

Customer has only a photo + handwritten dimensions — supplier refuses to build without a formal CAD drawing, so engineering bring-up stalls for two weeks while CAD is generated.

F-0101

4-hour DFM review

Engineering walks every RFQ within 4 business hours. Connector, wire AWG, tolerance, bend-radius risks flagged before quote.

F-0202

Multi-format drawing intake

EPLAN P8, Altium Designer, AutoCAD Electrical, Solidworks Electrical, Mentor Capital, STEP, DXF, annotated PDF, photo, hand-sketch with operator interview. Source format is the contract — no redraw.

F-0303

48-96 hour rush prototype

Rush prototype build from 1 unit to 100 units in 48-96 hours. Same workmanship as volume — not a separate process. Pricing 2.5× volume rate at 1 unit, declining steeply through 10 / 50 / 100 units.

F-0404

Obsolete-part detection

BOM intake cross-references every part against active distribution stock + manufacturer status. Last-time-buy or obsolete parts flagged at quote with replacement proposal.

F-0505

Production-ready validation

Prototypes built from the same stocked SKU library used for production — no substitute drift between prototype and volume builds.

F-0606

Engineering-drawing review service

Standalone engineering-drawing review service for customers wanting DFM feedback before committing to a supplier — flat-fee or no-cost depending on volume forecast.

Field Cases · ANONYMIZED CUSTOMER DELIVERIES

Real programs, real numbers.

Customer names redacted; specifications, volumes, and outcomes are preserved as delivered.

EV automotive OEM·US·2025-Q4

A US EV automotive OEM required an urgent NPI prototype run for a new vehicle harness package.

Challenge: The customer needed 50 units delivered within 15 days of PO issuance, requiring rapid procurement of authorized connectors alongside expedited manufacturing.
Solution: Fast-tracked the production schedule, secured authorized connector authorization within 48 hours through direct authorized-distributor relationships, and coordinated expedited logistics. NPI cell ran with deviation file gates at every shift handover to keep the build aligned to the active spec.
Result: Delivered the initial prototype batch on time, securing the customer's trust and a follow-on multi-PO repeat program for the vehicle platform across the program lifecycle.

Follow-on multi-PO program

The bottleneck in hardware development is not crimp speed — it is iteration speed. Hardware teams running EVT cycles need to spin a new harness revision weekly to validate the design path. At 10× single-unit pricing and 2-week DFM review they ration their iterations to monthly, which means they land in production three months late and with less confidence. We turn DFM in 4 hours and we price single-unit prototypes at 2.5× — and the hardware customer ships earlier with more rigor. That is the entire value proposition of the precision-quotation service; everything else (PPAP, FAI, ISO documentation) is just the volume side of the same discipline.

FAQ · SPEC_QUERIES

Procurement questions.

How fast is your DFM review turnaround?+

4 business hours on every RFQ. Engineering walks the drawing, flags connector / wire / tolerance / bend-radius / obsolete-part risks, returns the build sheet for customer sign-off. Standard procedure, not request-only. Rush DFM on urgent NPI gates in 1-2 hours available.

Will you build a 1-unit prototype?+

Yes — single-unit prototypes priced at 2.5× volume rate, not 10×. No MOQ floor for engineering validation builds. Same workmanship and operator pool as volume — prototype results are predictive of volume performance, not a separate process.

What drawing formats do you accept?+

EPLAN P8, Altium Designer, AutoCAD Electrical, Solidworks Electrical, Mentor Capital, STEP, DXF, annotated PDF, photo, hand-sketch with operator interview. We do not redraw — your source file is the contract. This preserves tolerance callouts, crimp tooling references, and footnotes that get lost in a Visio redraw.

Can you flag obsolete or last-time-buy parts on a BOM?+

Yes — BOM intake cross-references every part against active distribution stock and manufacturer lifecycle status (active / NRND / LTB / obsolete). Last-time-buy or obsolete parts flagged at quote with form-fit-function replacement proposal. We do not silently substitute — replacements require customer engineering sign-off.

Do you do a standalone engineering drawing review service?+

Yes — standalone drawing review for customers wanting DFM feedback on draft drawings before supplier commitment. Flat-fee for one-off reviews; no-cost for forecast volumes above a threshold. We treat the drawing review as a sales-funnel investment, not a billable line item, on serious programs.
