Latest Wire Harness News & Technical Insights

From Process Evaluation to Tooling & Fixtures, from NPI Validation to APQP System — Kaweei's Engineering Team Fully Deconstructs the Manufacturing-Side DFM Implementation Process for Wire Harnesses.

Bridging the Gap Between Wire Harness Design and Manufacturing — Terminal Insulation, Material Temperature Resistance, and Solder Joint Clearance: Every Detail Determines Mass Production Success.

I recently finished a batch of custom XT90 female connector harnesses for a client. In our shop at Kaweei, we deal with power connectors every single day. While the XT90 is a standard for high-current applications, I’ve seen countless projects suffer from "mysterious" power drops or overheating issues.

Pigtail connectors are widely used in automotive wiring, industrial equipment, LED lighting, and electrical repair applications. They provide a reliable and efficient way to connect electrical circuits while simplifying installation and maintenance.

In the electrical and electronics fields, connectors are the core to ensuring stable system operation. The application of high-performance copper alloys covers almost all electrical and electronic connectors and interconnect devices. For the wire harness industry, connectors must provide reliable mechanical and electrical connections between two components of an electronic system, without causing unacceptable signal distortion or power loss.

In the electronics manufacturing and wire harness processing industry, whether referring to the globally recognized IPC/WHMA-A-620 standard (Requirements and Acceptance for Cable and Wire Harness Assemblies) or the USCAR-21 standard, there is a core parameter that every wire harness process engineer must strictly adhere to: the tolerance of terminal Crimp Height, which is typically locked firmly at ±0.03 mm.
