- Solder mask must qualify to IPC-SM-840 and IPC-6012C, section 3.7. (IPC-SM-840E, Qualification and Performance Specification of Permanent Solder Mask and Flexible Cover Materials.)
- Visual acceptability guidelines per IPC-A-600 section 2–9 (class 3). (IPC-A-600H, Acceptability of Printed Circuit Boards)
- Masked board must meet 500VDC withstanding voltage test in accordance with IPC TM-650, TM 2.5.6.1. (IPC-TM-650, Test Methods Manual).
- As per IPC-6012C, section 3.2.7
- Silver immersion, reference IPC-4553A. (IPC-4553A, Specification for Immersion Silver Plating for Printed Circuit Boards).
- Tin immersion, reference IPC-4554. (IPC-4554, Specification for Immersion Tin Plating for Printed Circuit Boards).
- PCB’s must meet all requirements listed in IPC-6012C Section 3.3.
- No repair is allowed.
- PCB’s must comply with IPC-6012C, section 3.8.
- No repair is allowed.
- Suppliers do not deliver defective bare boards. The main reason is the tool IPC class 3, which gives awareness on the supplier side.
- When Autoliv suspects that a bare board delivery is not perfect, they has the right according to the IPC class 3 level to take part of the suppliers testand verification documentation. These procedures have helped them several times in their mission to reach a zero defect level.
- The company saves time, resources and money by relying on IPC standards and not having to develop their own.
- For more than five years, the company has saved millions dollars by decreasing defect rates, thus resulting in a better yield of defect free products.
