COOLER FOR REFLOWED SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a cooler for a reflowed substrate, for capturing a liquefied flux even if a flux gas in a cooled air flown to between a blowing plate and a substrate is liquefied. SOLUTION: The blowing plate 8 is installed above a carrying conveyer 5 and a substrate 7 in a cooling chamber 1. The blowing plate 8 is molded so that a cross section may be a mount. A plurality of blowing holes 8a penetrating through front and rear are formed on the blowing plate 8. A porous metal body 9 made of a metal having a high specific surface area is disposed so as to be integrated with the blowing plate 8. The porous metal body 9 captures a flux liquefied in a space between the blowing plate 8 and the carrying conveyer 5 and a flux passing through the blowing holes 8a of the blowing plate 8. The fluxes captured by the porous metal body 9 move to a flux collecting section 10a along its gradient. COPYRIGHT: (C)2010,JPO&INPIT
