Abstract
To save a space for heating remarkably than that of a conventional case, to apply main heating at a high temperature only to portions of chips to be soldered and to perform heating operation in a short period of time, a heating apparatus is composed of a preheating zone and a main heating zone. In the preheating zone, support pallets are rotated in the vertical direction within a vertical heat insulating chamber like a Ferris wheel. Also, heat at a temperature such that cream solder is not molten by heaters is applied to a printed circuit board by fans. In the main heating zone, a pattern mask is fixed within a heat insulating chamber, sleeve bodies are fitted in necessary through-holes, blind plugs are fitted in unnecessary through-holes and heat at a temperature such that the cream solder is molten by a heater is applied to portions of chips to be soldered by fans through sleeve bodies, coil springs and other sleeve bodies.
