Hearing your advice, I got some doubt on no-clean flux, and find following report.
"No-Clean Flux: The Use of Multiple Vendors Can Produce a Reliability Time Bomb" http://www.aimsolder.com/techarticles/Incompatibilities.pdf The impressive part of this article is, In a hand-soldering operation with rosin-based fluxes, a liquid flux is often used in conjunction with a cored wire. But the liquid flux never sees the necessary passivating temperature. The most important fact to remember about no-clean soldering is that no-clean fluxes are only safe after they, in their entirety, have seen passivation temperature. Thank you Kai for reminding me this fact. Tsuneo |
