Abstract
Pressurized molten solder 71 is flowed along a confined first channel 86 and forced through a series of spaced, aligned apertures 88 as solder jets which rise, fall and merge to form a solder stream which flows along a second channel defined by channel walls 93 and 94. Spring held printed circuit boards 10 are advanced by a conveyor 21 which is tilted to move a far section of each board into engagement with the top of channel wall 93 and then a near section of each board into engagement with the top of channel wall 94 whereafter the board is spring held to ride along the tops of channel walls while a thin stripe of solder is applied to the board.
