Abstract:
1. A method of applying solder to an electronic circuit board substrate comprising: providing a substantially planar electronic circuit board substrate having a pair of opposing surfaces, the substrate having on one surface thereof at least one protruding connector to be soldered and at least one component not to be soldered; providing a solder wave device adapted to generate a molten wave of solder; providing beneath the substrate a substrate holder movable in a direction with respect the molten solder of the solder wave device, the substrate holder having a support for the substrate inclined at an angle with respect to said direction and an opening on a bottom thereof for access of the at least one protruding connector to the molten solder wave of the solder wave device, the angle of incline sufficient to prevent the at least one component not to be soldered from contacting the molten solder wave of the solder wave device when the substrate holder is moved in said direction over the solder wave device; positioning the substrate in the substrate holder such that the at least one protruding connector is exposed through the opening on the bottom thereof; generating a molten solder wave with the solder wave device; and moving the substrate holder with respect to the solder wave device in said direction such that the at least one protruding connector exposed through the opening on the bottom thereof contacts the molten solder wave while the at least one component does not contact the molten solder wave.
