Title:
REFLOW DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/120526
Kind Code:
A1
Abstract:
An inlet for N2 for cooling is provided below lower heating devices.
N2 is supplied from below to the respective lower heating devices of
zones (Z3-Z5) for performing preheating. N2 supplied from an N2
generation device (45) is divided by a branch section (46) into main supply and
sub-supply for cooling. The sub-supply route is branched to three, and each of
the branched routes has a valve (V3-V5) and a flow rate regulation volume (L3-L5).
The conduction and interruption of the N2 for cooling relative to the
zones (Z3-Z5) are controlled by switching the valves (V3-V5). In switching of
lead-free solder to eutectic solder, N2 are introduced into the lower
heating devices of the zones (Z3-Z5) to quickly lower the temperature of these
zones.
