Abstract: An electronic component tinning apparatus comprising a longitudinal base unit having two longitudinally extending sides connected to a first end and an opposing second end, a top portion connected to and bounded by said sides and ends with an open longitudinal central cavity, and two spaced-apart, parallel longitudinally extending rails mounted on the top portion on opposing sides of said central cavity; a flux tank mounted in said central cavity approximate said first end to hold a liquid flux for flux-coating electronic component leads; a heated pot mounted in said central cavity approximate said second end to hold a hot molten solder bath for tinning the electronic component leads; a powered, wheeled electronic-component transport adapted to ride on said rails to carry electronic components from said first end over the flux tank to the second end over said solder pot and back again; two powered cam means mounted in said transport, rotatable to a high transport position and a low processing position, said c

Abstract: A process for soldering circuit boards comprising the steps of:(a) applying a solder flux coating to the solder side of a board;(b) drying the flux on the board and preheating the solder side of the board by sequentially(i) directing a stream of warm gas over the solder side of the board,(ii) positioning the solder side of the board over a hot molten solder bath,(c) soldering the solder junctions on the board by immersing the solder side of the board into the surface of the hot molten solder bath by sequentially(i) immersing a first edge of the board into the surface of the solder bath,(ii) lowering the remainder of the board into the surface of the solder bath,(iii) longitudinally moving the board in the solder bath, and(iv) lifting the board from the surface of the solder bath at an angle to the surface of the solder bath to drain excess hot molten solder from the board.

Abstract: An improved magnetic tape reel for computers is taught which comprises a central part carrying a driving hub having a first set of spokes extending radially outward from the outer surface of the hub and a support ring concentric with the hub and having a second set of spokes extending radially inwardly from the inner surface of the ring. Two side flanges are ultrasonically welded to the central part along the spokes forming a box-like structure having a high resistance to compression produced by tape being wound thereon.
