Abstract
1363431 Soldering JOSEPH LUCAS (INDUSTRIES) Ltd 15 Nov 1971 [24 Nov 1970 25 Feb 1971] 55721/70 and 5484/71 Heading B3R [Also in Division H1] In connecting a semi-conductor chip having solderable projections to a substrate, a plurality of conductive areas 11 are provided on the substrate, each area including a terminal portion 12 and a narrower neck portion 13, a dam 14 formed of a material which is not wetted by solder is provided on each neck portion 13, molten solder is provided on the terminal portions, the dimensions of the neck portions being such that flow of solder away from the terminal portions is resisted and the arrangement being such that a raised solder land is formed on each terminal portion, the projections on the chip are engaged with the lands and the assembly is heated to fuse the solder. The length of each portion 13 is not less than 1À5 times the length of its portion 12 and its width not more than half the width of its portion 12. The portions 12 although shown square may be circular and the neck portions 13 may be other than rectangular. The dams may be of glass. When the molten solder 14 is applied only a very thin coating is formed on the neck portions with a large amount on the portions 12 and remainder of area 11. The chip is inverted so that solder pads or copper balls soldered thereto are presented to the lands which when the assembly is heated form the soldered connections. More than one neck portion may be provided to join a terminal portion to the rest of the conductive area.
