Abstract:The IPC’s test method on cleanness of printed circuit board were improved. Water bath -heater combined with nitrogen-blow was proposed as a disposal method of sample. Interference of isopropanol on measure was removed effectively, and the sample was concentrated. Weak organic acids in the sample were separated effectively and examined successfully. The results show that this disposal method could make the result more exact, and its interference is small. The detection limit is 3 ng/mL (Cl–).
