LarryK, It all depends upon your volume / problem. As Jax says, if this is a repeating problemo, get QA & Purchasing involved. Is it your stores ? Do they receive 100 off and "decant" 20 into a tube (manual handling error, training etc;). From your

Is the demand for in-circuit testing still high for PCBA?
