Decoupling Nonrecurring Engineering Expenses from Unit Component Pricing in Turnkey Hardware
Uncoupling engineering charges from unit component costs prevents perpetual margin penalties and secures design ownership for secondary factory transfers.
Custom Jig Calibration
Meaning
Metrological process that aligns and verifies the accuracy of specialized test fixtures used to hold and probe printed circuit boards during production line testing. For high-volume consumer electronics, custom jig calibration ensures that pogo pins strike the designated test points with repeatable force and millimeter-level positioning. This procedure is inapplicable to standard generic test benches that do not use product-specific guides.
Mechanical Wear
Friction and repetitive mechanical stress degrade the alignment of guide pins over thousands of insertion cycles. Regular custom jig calibration identifies this physical deviation before it leads to false test failures or damaged test pads on production boards. An uncalibrated fixture can bend delicate RF probe tips or scratch the solder mask of the product under test.
Measurement Accuracy
Precision instruments require stable electrical and physical reference points to deliver valid test results. When custom jig calibration is performed, technicians use master boards with known electrical characteristics to map the resistance and capacitance of the signal paths. These calibration data files are stored directly on the test station computer to compensate for systemic noise in the wiring harness.
This compensation prevents good boards from being incorrectly flagged as defective, which keeps the assembly line running at its target rate.
Production Schedule
Factory throughput depends on having multiple validated fixtures ready to support the assembly line. Because custom jig calibration requires taking a test station offline, it is scheduled during planned shift changes or maintenance windows. Scheduled verification minimizes the risk of line stoppages while maintaining the traceability required by quality management standards.
