1. K8418A Surface Insulation Resistance (SIR)
2. Copper Mirror Corrosion Test (IPC-TM-650, Test method 2.3.32)
Objective:
The purpose of this test is to help define the level of activity of the flux and determine the corrosive (halide free) properties of a flux.
Procedures:
Flux is applied to copper-coated glass slide and sits in a controlled environment al chamber (23±2℃, 45~55%RH) for 24hours.
3. Copper Plate Corrosion – Passed
Objective:
The purpose of this test is to determine the corrosive (halide free) properties of a flux.
Procedures:
Flux is applied to copper-coated glass slide and sits in a controlled environment (40℃, 93%RH, 72h)
4. 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.
Procedures:
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
