Latest Wire Harness News & Technical Insights

In the New Product Introduction (NPI) process for custom electronic wire harnesses, engineering teams are most often stalled not by "can it be made", but by "whether the sample meets the customer's functional quality requirements, whether validation data is usable, and whether it can seamlessly transition to mass production".

Every wire harness must pass specified electrical and functional verification before shipment. This is not a slogan, it is the quality baseline embedded in Kaweei's manufacturing process.

AWG and mm² are two different ways of specifying conductor size. AWG is commonly used in North America, while mm² is widely used in IEC-based cable specifications. This guide explains the difference between AWG and mm², provides a practical conversion chart, and shows how to choose the right wire size for a wire harness or cable assembly.

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.
