You are in the Printed Board Quality Business Nearly everything electronic in the universe depends on the printed circuit board (PCB). For many years, the IPC-A-600 Acceptability of Printed Boards and IPC-6012 Qualification and Performance Specification for Rigid Printed Boards documents have set the standard for PCB workmanship quality, giving comprehensive acceptance criteria with full color illustrations and photographs showing all types of printed board surface and internal conditions. Because of its importance to both the PCB manufacturer and assembler, the IPC-A-600 has become one of the most widely used documents ever published by IPC.
