| 20100143658 | SOLDER FLUX - A soldering flux composition comprising: (i) a carrier vehicle comprising a solvent; (ii) an activator component for activating a metal surface for soldering; (iii) a colour-imparting component with an appropriate colour to facilitate optical detection of flux on the fluxed component; and optionally (iv) a gelling component to control flux rheology. The colour-imparting component is utilised to indicate the presence of desired amounts of flux. A component with inadequate flux for reliable soldering can be rejected. | 06-10-2010 |
