| 111 | Method of soldering an electronic component with a high lateral accuracy | US14414918 | 2013-07-17 | US09198302B2 | 2015-11-24 | Gordon Patrick Rudolf Elger |
| The present invention relates to a method of soldering an electronic component (3) to a substrate (1) with high accuracy using transient liquid phase soldering. The component (3) is exactly positioned above the substrate (1) with a handling tool, placed in the melted solder (2) and pressed against the substrate (1). The component (3) is then released and the solder (2) allowed solidifying. Due to the use of a solder (2) having a sufficiently high amount of a second metal or metal alloy of a higher melting point which only partly dissolves in the melted first metal or metal alloy of a lower melting point, a solid framework forms during the liquid phase soldering which inhibits a lateral movement of the placed component (3) during soldering. Since the positioning of the component (3) is made using exact reference features on the substrate (1), the whole soldering process results in a highly accurate lateral position of the soldered component. | ||||||

| A brazing method includes fixing a padding plate on a base material such that the padding plate is arranged in a lower position from a groove formed in a repair region of the base material, and heating the base material such that a base material powder is melt, after a paste that base material 1 contains the base material powder which is formed from a same material as the base material is filled into the groove. The base material powder filled into groove can be prevented from flowing out from the groove even if being fused since the padding plate is arranged for the base material. Thus, a repair region can be repaired more appropriately. | ||||||
