Practical resistance specifications

The IPC\WHMA-A-620 Rev A standard states that in the absence of agreement on test requirements between manufacturer and user the continuity spec for class 3 assemblies should be 2 ohms, or 1 ohm plus the actual resistance. We agree that this is a reasonable method for determining continuity test specs. However, when more stringent continuity…

Ergonomics and Cable Testing

Safety in the workplace means more than just identifying and eliminating hazards. Maintaining good employee health is important to company morale and production. An employee bent over testing cables for hours or leaning across a table to thread a wire through a harness could experience chronic pain not easily alleviated. Addressing problems that cause employees…

Moving Tests Upstream

By adding automated testing earlier throughout the build process, cable and harness manufacturers can find errors sooner; this saves time, money, and provides a competitive advantage. Rising expectations in the cable/harness industry demand that manufacturers build more complex assemblies in less time. Accomplishing this feat means manufacturers must re-evaluate their processes. How can shops produce…

Testing Tips – Correct Resistance Settings

Do you know the correct resistance settings when building a new test program? While the default settings may work in most situations, you may find tests failing because of a wrong setting—not because of a bad cable. One of the most common settings in a situation like this is the resistance setting. The resistance values…

Testing Cables with High Voltage

Many people are familiar with a continuity test. A continuity test checks for “good connections,” meaning current will flow from one point to its destination point. If current flows easily enough then the points are connected. Many people are less familiar with a hipot test. “Hipot” is short for high potential (high voltage). A hipot…
