Torch Assembly

The torch assembly apparatus applies a plurality of discrete miniature flames at a plurality of points within a confined area.

The apparatus is utilized to apply localized heat to contact points between the pins of the upper member of a pair of stacked modules and the substrate of the lower member. Carriage member 10 places upper module 11 stacked upon the surface of lower module 12 which is held by suitable retaining means 13. As shown in A, and in greater detail in C, each pin 14 of module 11 registers with the head of a pin 15 of module 12. The contact between registered pins is to be made secure by heating and reflowing solder 16 at the contact point. Localized heating of the sixteen contact points is accomplished by sliding torch banks 17 and 18 in the direction shown into engagement with the stacked modules. The arrangement of the torch banks, when engaged with the stacked modules, is shown in B which is a section through the space between the stacked modules.

Each torch bank contains manifold 19 through which the gas to be ignited is supplied to torch tubes 20. Each tube 20 has apertures 26 adjacent to the points to which the localized heat is to be applied. Jet flames issuing from a pair of such adjacent apertures are applied to each of the sixteen contact points. Because of the confined space between the stacked modules, heat dissipation can be controlled. The discrete nature of the individual jet flames can be maintained only by the suppl...
