Identifying Hidden Engineering Labor Allocations within Factory Unit Quotes
Factory unit quotes bury design, test jig, and maintenance hours in piece prices, requiring unbundled SOW line items to isolate engineering labor and IP rights.
Test Jig Development
Meaning
A hardware engineering project involves the design and construction of specialized equipment to automate the testing of a specific product. The test jig development includes the creation of the bed of nails fixture and the software that controls the measurement sequence. It is a necessary investment for high volume electronics manufacturing.
Engineering Effort
Designing a custom fixture requires a deep understanding of the product’s electrical interfaces and mechanical dimensions. Successful test jig development results in a robust tool that can withstand thousands of insertion cycles without failing. This work is usually performed in parallel with the main product design.
Functional Design
The fixture must be able to power the device and simulate its normal operating environment while monitoring for defects. During test jig development, engineers must account for signal integrity and shielding to ensure that the measurements are not affected by external noise.
Deployment Readiness
Once the equipment is built, it must be validated at the factory to confirm that it integrates with the production flow. The test jig development phase ends when the tool is consistently identifying known good and bad units. This equipment is the primary gatekeeper for quality in the assembly hall.
Well designed jigs reduce the need for manual inspection and lower the overall cost of quality.
