Test-Centric Assembly

May 21, 2009
Test-Centric Assembly is best defined as the upfront consideration of real-world test requirements in test-intensive assembly operations that is proven to lower production line inefficiencies.

Test-Centric Assembly is a best-practice approach for any test-intensive assembly operation. A common, but far less satisfactory approach to machine building of test-intensive assemblies is to consider testing as an afterthought to overall machine design. This often means that the real testing requirements of an assembly and test application are misunderstood. This less than optimal approach typically compromises Gauge R&R. In many cases, defective part problems are predominant and there is an inability to diagnose whether testing processes are lacking and creating erroneous defect readings or if real defects in the parts are at issue.

Hallmarks of test-centric assemblies are expert fixture design and integration of both hardware and software at the system level. Test-centric assembly refers to the entirety of the applications engineering knowledgebase that enables testing experts with a singular focus on testing to improve production speed and yields in test-intensive operations.

This white paper reviews the general principles of test-centric assembly for manufacturers and machine builders more accustomed to streamlining assembly operations where testing is absent or plays a minimal part.
