ABSTRACT:
A process and machine are disclosed for reflowing solder plated continuous flexible circuit webs. During reflow in a vapor environment, the flexible web is maintained in a planar orientation to produce a relatively uniform distribution of solder. Virtually all of the heat transfer fluid used in producing the vapor is recovered and retained.
