EFFICIENCY ESTIMATION OF INFRARED HEATING SYSTEMS FOR MOUNTING ELECTRONICS MODULES

Vladimir Leonid Lanin

Abstract


The efficiency of shortly - and middle-wave infrared (IR) sources of heat applied to mounting and demounting of electronic modules is sized up. Thermal fields models analysis shows IR lamps irregularity of heating of the PCB and packages of electronic components. For ceramic IR radiator irregularity of heating of the PCB makes 8-13°С, the temperature SMD components packages differs from plate temperature on 5-20°С. Application middle-wave ceramic IR sources allows to attain higher uniformity of heat in a working area and to ensure optimal temperature profile at mounting and demounting of surface-mounted electronic components.
