Designing printed circuit boards today is more difficult than ever before due to significantly increased density, higher lead free processing temperatures and the associated changes required in manufacturing. The entire supply chain has also been impacted by requirements regarding the use of hazardous materials and recycling. The RoHS and REACH directives have caused suppliers throughout the industry to change both their materials and processes. So, everyone designing or producing electronics has been affected even if they’ve been part of categories designated as directive exempt.
Printed Circuit Boards (PCBs) should always be considered a critical commodity. Without stringent controls in place for PCB supplier selection, qualification, and management, long term product quality and reliability is neither achievable nor sustainable. This paper builds on the Part I paper and further expands it with auditing recommendations and case studies of defects .
