Preparation

Component kitting guide

Preparing your parts drop-shipment

To keep bench processing fast and avoid assembly delays:

  • Label all component bags with the corresponding BOM item numbers.
  • Include 5% extra crimp terminals and wire length for setup calibration.
  • Include pinout diagrams, torque specs, or potting depth limits in your package.

Who we serve

Industries served

4x4 & automotive

We build high-reliability custom switch panels, potted relay blocks, and ruggedized vehicle electronics engineered for extreme conditions. Every wiring harness and module is assembled to resist constant off-road vibration, heat exposure, and severe terrain demands.

Industrial OEMs

Our workshop provides dedicated overflow bench capacity, control box wiring, and precision sensor potting for commercial equipment manufacturers. We help industrial OEMs eliminate assembly bottlenecks with rapid-turn small-batch execution and strict adherence to build specifications.

Marine systems

We fabricate fully sealed, water-tight wiring harnesses and epoxy-encapsulated circuitry designed specifically for harsh saltwater environments. From marine instrument clusters to underwater sensor blocks, our potting process guarantees long-term protection against corrosion and water intrusion.

Creators & prototypers

We partner with hardware inventors, makers, and boutique product developers who need professional bench execution without factory minimums. Whether you need initial prototype wiring, specialized PCB sensor integration, or short-run product assembly, we bring high-end manufacturing quality to your custom builds.

FAQ

Frequently asked questions

What is your minimum order quantity (MOQ)? +

We specialize in prototype and small-batch production, typically 5 to 50+ units, and can accommodate custom low-volume runs based on your requirements.

How does the consignment model work? +

You buy and drop-ship your circuit boards, connectors, and raw components directly to our workshop. We provide bench labor, soldering, assembly, and encapsulation, charging strictly for labor without marking up your parts.

What is your standard turnaround time? +

Most standard small-batch orders (10-30 units) ship within 3 to 5 business days after component drop-shipments arrive. Expedited execution is available on request.

Do you sign non-disclosure agreements (NDAs)? +

Yes. We regularly work with proprietary OEM designs and custom electronic sub-assemblies, and are happy to execute standard NDAs before reviewing your CAD or manufacturing specs.
