You stated that you are producing Class 3 boards so I assume you are familiar with the IPC standards.To answer your question directly, I'll refer you back to the J-STD-001. Clause 12.1 states "12.1 Rework Hardware defects shall [N1N2D3] be documented

You bet our reponse changes. Q2R: Hard gold thickness is 4 to 10 u" for Au and 300 to 400 u" for nickel A2R: This is a hard gold spec?? It looks like a ENIG spec. Although, the Ni is quite heavy, 150 uin is sufficient for most applications. The gol

Does anyone know there a standard matrix of clearances part to part for Class 2 and Class 3 board design. IPC does issue a preferred matrix but they are so liberal they not so useful in the real world. Any suggestions would really be appreciated.
