Wire-harnesses are, to contemporary devices, like the human circulatory and nervous systems are to a body—both transport energy and data from place to place. Like in a human, errors and faults in harnesses can result in severe degradation or even complete failure of a system.
Nearly half—49%—of all wire-harness problems can be traced directly to poor workmanship. Knowing this, Juscom, Inc. adheres to, and actually exceeds IPC/WHMA-A-620B Class 3 standards for all work, even when the customer is not using the harness in safety-critical applications.
Examples of where we exceed IPC/WHMA-A-620B standards include our monitoring of crimp quality. Each crimp is monitored in real-time as it is formed, the force profile used to accept or reject the crimp. Crimp samples are also periodically cross-sectioned to ensure the profile conforms to best-practice standards. Periodic pull-force and cross-section measurements---indicators of crimp quality---are also taken as part of our quality control process.

IPC/WHMA-A-620 defines three classes of product:
Harness being assembled with the aid of a computerized nailboard.
Most customers do not need Class 3 quality. However, because excellent quality requires that only one quality standard and culture be used in an organization, Juscom, Inc. works only to Class 3 standards.
