Abstract
A variable parameter heater for applying heat in a predetermined profile to a work surface. The heater has a plurality of elongated members which are interconnected to form a frame. Elongated members are slidingly adjustable to provide the intended heat profile. Each elongated member contains first and second rows of apertures. Heated air is delivered to the work surface past selectively energized heating elements disposed in the first row of apertures. Cool air where required is delivered to the work surface through the second row of apertures. The heater may include a vacuum probe for depositing or removing components relative to the work surface. The vacuum probe may also direct cool air to the work surface. Mirrors may be mounted upon elongated members to provide enhanced viewing of the work surface. In case of disablement, elongated members are individually removeble for repair or replacement.
