Rosin (alcohol-rosin, 90ml)

Acid-free flux based on absolute isopropyl alcohol. The content of water and other impurities in it does not exceed 0.5%. Average resistance between tracks at 0.5mm pitch, usually close to10 Mohm. Due to the high residual resistance, it can be used for solderinghigh-voltage, high-resistance, high frequency circuits. Soldering boards with this flux is quite difficult. Therefore, it is still preferable to usefluxF1(4.5MOhm),which is an order of magnitude more active, and wash off the remaining flux with a remover for printed circuit boards.
