In the case of flux c

48、ored solders and solder pastes, a standard mass of the material is melted on the copper test piece. After the test piece has cooled to room temperature, the flux residues are tested for tackiness using chalk powder.5 Reagents and materialsIn the test, only reagents of recognized analytical quality a
