Why Engineers Choose WellPCB for Coaxial Cable Assemblies

When signal integrity determines whether your system meets spec or fails qualification, your coaxial cable assemblies cannot be an afterthought. Every decibel of insertion loss, every point of VSWR, and every degree of phase stability matters — especially at frequencies above 6 GHz where marginal assemblies degrade system performance.

WellPCB manufactures custom coaxial cable assemblies for RF engineers who need repeatable, tested, and documented performance across thousands of units. Our IPC-certified technicians build with cables and connectors from leading manufacturers, and every single assembly ships with verified electrical test data — not sample-based lot testing, but 100% individual verification.

From single prototype assemblies for lab validation to production runs of 50,000+ units per month for telecom infrastructure, we deliver the same quality standard with full material traceability. Our five manufacturing facilities across four countries let you source locally while maintaining consistent specifications globally.

Our Coaxial Cable Assembly Process

Six steps from your specification to fully tested, certified cable assemblies

01

Requirements Review & Design

Our RF engineers review your specifications, select the optimal cable and connector combination, and provide a detailed assembly drawing for your approval.

02

Material Procurement & Verification

We source genuine cables and connectors from authorized distributors. All incoming materials are inspected and verified against manufacturer specifications.

03

Precision Cable Preparation

Automated cutting to ± 0.5 mm tolerance. Multi-step stripping with controlled dimensions for each cable layer — jacket, shield, dielectric, and center conductor.

04

Connector Termination

Expert solder or crimp termination by IPC-certified technicians. Each termination is visually inspected under magnification and pull-force tested to manufacturer specifications.

05

Electrical Testing & Certification

100% testing of every assembly: continuity, VSWR/return loss sweep, insertion loss, and dielectric withstand voltage. Test data recorded and traceable to each serial number.

06

Labeling, Packaging & Delivery

Custom labeling with serial numbers and test data. Anti-static packaging with protective caps on all connectors. Global shipping with lead times from 5 to 15 business days.

“
In RF cable assembly, the difference between a good product and a failed one often comes down to termination quality and testing rigor. We test every single assembly — not batches, not samples — because our customers' systems depend on consistent performance from the first cable to the ten-thousandth.
