I would like to manually wire lead end immersion tin, do not know what kind of flux selected, and the proportion of the flux does not know, check for a long time did not find, please heroes help ah?
Hydrochloric acid has been used in large cross-section conductors. Small section, the market has the sale of flux, the price is not expensive.
The flux is matched with a chemical liquid. Taking the question, I'm telling you the secret recipe
No cleaning flux can be used. Manufacturers, models are many.
