1)What is the MSD level for PCB? 2)I have some PCB's with HIC (humidity indicator card ) has turn to pink at 50%. Should I bake the PCB prior to assembly process.This fab is a complex board with various kind advance package assembled on the board.

Why to use 5% color spot in HIC if level 2a-5a are considered bad when 10% is NOT blue ? 10% will be NOT blue(or pink) only after 5% is pink. Then why to keep 5% in HIC ?

While inspecting incoming PCBs we detected around all plated-through-holes (only there and all in the same place) some halfmoonshaped light rings that match obviously only with the pink ring symptom shown in the IPC-A-600 chapter 2.5.2.. That would m
