Hello,

I have tested it with quite good SIR results BUT do not use it for BGA:s. There are large voids in the solder joints for BGA:s. I was very disappointed as it had quite good results otherwise. We tested it on FR4 and microwire boards. Please let me know if you have further questions.

I am looking for a supplier for small quantities of Kester HF1189 Flux.
This is supposed to be a high activity, citrus based, water soluble flux.
Any one using it? Comments?
