Cobar wave soldering flux 390-RX-HT

This high-reliability flux is specifically developed for higher thermal impacts (high/long preheat with increased contact times) like in Pb-free wave soldering. The flux shows high SIR values under the most critical test conditions.

IPC J-STD-004 classification REL0
