IPC Class 3 compliance requires minimum 75 percent vertical barrel fill and under 15 percent internal voiding verified via precision microsectioning.
Non-Conformance Penalty
Financial Liability
Monetary charge levied against a manufacturer for delivering printed circuit boards that fail to meet the agreed technical specifications or quality standards. A non-conformance penalty provides a mechanism to recover the costs associated with inspection, testing, shipping and production delays at the assembly site. It applies when the delivered lot contains defects that exceed the acceptable quality limit defined in the procurement contract.
This fee is distinct from standard warranty claims because it addresses the immediate operational loss caused by faulty intake.
Contractual Enforcement
Contractual enforcement begins when a formal notice of rejection is issued following an automated optical inspection or x-ray failure. The non-conformance penalty often includes the cost of sorting mixed batches and the labor required for rework or disposal of the scrap material. Calculation of the fee depends on the severity of the deviation and its impact on downstream production schedules.
Risk Mitigation
Risk mitigation and supplier accountability are the primary drivers for these commercial terms. The non-conformance penalty acts as a deterrent against poor workmanship and motivates the fabrication house to maintain rigorous process controls. Final settlement of these charges typically occurs during the quarterly business review or through immediate credit notes against the purchase order.
