摘要:
A method and apparatus for the forming of a solder deposit (2) on an SMD pad (4) on a printed circuit (3) or hybrid circuit board, the formed solder deposit (2) itself as well as a circuit board with the solder so formed thereon. This formed solder deposit (2) is in a defined three-dimensional well having the proper profile and a defined solder gap. By the placement of a mesh (14) on the surface of the circuit board with the solder in place on the pads, applying a slight positive pressure on a rigid or elastic surface (13) on the other side of the mesh, and subjecting this system to a temperature just low enough to reflow the solder by means of a heat transfer fluid, thereby the laminate structure of the board and the coating thereon remain substantially unaffected, then cooling the board to solidify the solder, a product results having the above properties.
