We build custom cable assemblies for OEMs across the US, Europe, India, Southeast Asia, and the Middle East. Our Shenzhen factory handles everything from LVDS display cables to waterproof industrial harnesses — most projects ship in 10–14 days once samples are approved. MOQ starts at 100 sets for standard orders, with lower quantities available for prototypes. We work with I-PEX, JST, Molex, Hirose, JAE, and KEL connector families, which covers roughly 95% of what comes through our quoting desk. If you’re replacing a discontinued part, send us the drawing or a physical sample and we’ll match the specs.
What Is a Cable Assembly?
A cable assembly is a group of wires, cables, or sub-components bound together to transmit signals or power between two devices. It’s different from a single cable in that it typically has connectors on both ends, and it may include overmolded housings, shielding, or strain relief.
Wire harness is a close cousin. The terms overlap in everyday use. Most engineers use cable assembly to mean a cleaner, connector-terminated unit for signal or low-power applications, and wire harness for more complex multi-branch wiring bundles often used in automotive and industrial equipment. In our factory, we make both.
Cable Assembly Types We Manufacture
Our cable assembly service covers the most common signal and power variants B2B buyers specify. Click through for technical details on each type:
- LVDS Cable Assembly — high-speed display cables using I-PEX and JAE connectors. Common in laptops, industrial monitors, and medical imaging.
- eDP Cable Assembly — Embedded DisplayPort for modern laptop panels. Supports up to 4K at 60Hz.
- Micro-Coaxial Cable — ultra-fine 40–46 AWG coax for AR/VR headsets and medical endoscopes.
- MIPI Cable — CSI/DSI interface cables for camera modules.
- RF Cable (U.FL / MHF) — antenna cables for WiFi, 5G, and IoT modules.
- Medical Cable Assembly — ISO 13485 compliant cables for patient monitoring, imaging, and diagnostic devices.
- Custom Cable Assembly — fully bespoke designs for projects that don’t match any standard category.
Cable Assembly Specifications We Support
Here’s a quick reference for the parameter ranges we quote on:
| Parameter | Range |
|---|---|
| Pitch | 0.3 mm – 5.08 mm |
| Pin Count | 2 – 240 positions |
| Wire AWG | 20 AWG – 46 AWG |
| Current Rating | Up to 9 A per contact |
| Voltage Rating | Up to 300 V |
| Operating Temperature | -40 °C to +125 °C |
| Cable Length | 30 mm to 5,000 mm |
| Compliance | RoHS, REACH, UL, CE |
| MOQ | 100 sets (standard), lower for samples |
If your spec falls outside these ranges, send us the drawing anyway. We’ve done stranger things.
Typical Applications
Our cable assemblies show up in six main product categories:
Laptop and monitor displays. Our biggest category. Most are LVDS or eDP assemblies going to ODM factories in Taiwan, China, and Vietnam that then build panels for brands in the US and Europe.
Medical imaging equipment. Ultrasound probes, endoscopes, patient monitors. These jobs demand ISO 13485 workflows and documented material traceability. Single-use and reusable devices have different cable specs, and we track both separately.
Industrial automation. Control panels, PLC wiring, servo drive connections. Usually JST or Molex terminals, sometimes waterproof to IP67 for factory floor environments.
Robotics. Cobots, service robots, and lately a lot of humanoid robot subassemblies. These need high-flex-life cables — some specs call for 5 million bend cycles over the product lifetime.
Consumer electronics. Smart speakers, security cameras, drones, wearables. High volume, tight cost targets, fast turnaround. We run this segment as a separate production line to protect lead times on industrial and medical work.
Automotive infotainment. Head units, center console displays, rear-seat entertainment. IATF 16949 process required. This segment is smaller for us but growing with the EV wave.
Why OEM Buyers Choose SZFRS
Choosing the right cable assembly supplier comes down to a few things. We don’t try to be the biggest cable factory in Shenzhen — we try to be the one that engineers want to work with again. Here’s what we do differently:
Engineering review before quoting. Every new project gets looked at by our senior engineers. If the drawing has a mistake or a spec is unrealistic, we tell you before the quote. Saves everyone time.
Real sample policy. First samples are free for evaluated projects. We don’t treat prototypes like mini production runs — small-batch fixturing is part of our workflow.
IPC/WHMA-A-620 trained operators. All crimp and solder operators are certified. QC team audits to Class 2 by default, Class 3 on request. See our quality and certifications page for the full list.
Traceable material sourcing. Every connector and wire spool has a lot code. If a field failure ever happens, we can trace the exact batch. This matters more for medical and automotive programs than for consumer work, but we run the same system across the floor.
Response time. Quote in 24 hours for standard projects. Sample in 7–10 days. Production in 10–14 days for repeat orders.
Our Cable Assembly Manufacturing Process
Every cable assembly runs through the same seven steps:
- Engineering review. Drawing audit, BOM check, DFM suggestions if applicable.
- Material sourcing. Connectors, wire, overmolding resin — all from approved suppliers with lot tracking.
- Cutting and stripping. Automated cutters for volume, manual for low-count precision work.
- Crimping or soldering. Certified operators, crimp height verification every 250 pieces minimum.
- Assembly. Housing insertion, overmolding if specified, strain relief, labeling.
- Testing. 100% continuity, hi-pot, pull force per WHMA-A-620. Electrical testing on request.
- Packaging. ESD bags, moisture barriers where needed, custom labeling for ODM buyers.
For medical and automotive programs, we add documented inspection records and material certificates. See our manufacturing capabilities page for the full equipment list.
Frequently Asked Questions
What’s your MOQ for custom cable assemblies?
100 sets is our standard MOQ for production orders. Prototype batches of 10–50 are possible with NRE fees, though we try to keep those reasonable for projects that look headed to production. For long-term programs we sometimes run MOQ as low as 50 sets with a blanket order.
How long does prototyping take?
Most prototypes ship 7–10 days after drawing approval. If the project needs custom tooling or connectors we don’t stock, add 2–3 weeks. We’ll tell you the honest timeline during quoting — no surprises.
Do you work with customer-supplied components?
Yes. Many of our clients have a preferred connector supplier or provide special wire for medical applications. We inspect and inventory the supplied parts separately, and we note customer-supplied items on quality records.
What certifications does SZFRS hold?
ISO 9001, IATF 16949 for automotive, ISO 13485 for medical, IPC/WHMA-A-620 Class 2/3, RoHS, and REACH. Full documentation is available on the quality and certifications page.
Can you ship to Europe and the US?
Yes — these are our two biggest markets. We ship DDP, DAP, and EXW depending on client preference. FedEx, DHL, and UPS handle samples; ocean and air freight handle production quantities. We prepare US Section 301 tariff documentation for clients importing to the US, and we work with clients’ EU customs brokers for VAT and CE compliance.
What if we only have a physical sample, no drawing?
Send it over. We’ll measure, photograph, and generate a working drawing for your approval before production. About 20% of our repeat orders start this way — from a failed part, a legacy sample, or a competitor’s cable that needs a drop-in replacement.
What drawing file formats do you accept?
PDF works for most projects. For complex harnesses we prefer STEP, IGES, or DWG. A Bill of Materials with connector part numbers and wire spec is almost always faster than a drawing alone. Just send what you have.
