Quantitative Halides (Cl, Br) (IPC-TM-650, Test method 2.3.28.1)
Objective
The purpose of this test is to determine the total halide concentration of a flux.
Procedure:
Flux is dissolved to pre-determined concentration. Extracted solutions are then analyzed using an ion chromatograph with 3 to 5 level calibration. Total halide content is calculated and reported at Cl equivalent.
Results:
Total halides <0.05% Cl equivalent
