Convective Module

Convective Module TowerThe Convective Module (CM), sub-room temperature flatness measurement module, is used hand-in-hand with Akrometrix’ patented TherMoiré® technology. The module, when coupled with the TherMoiré® system, enables automated phase-stepping analysis and convective cooling down to -50°C and heating up to reflow temperatures. For example, the Convective Module can duplicate reliability testing as required for JEDEC temperature cycling initiative JESD22-A104-B.

The Convective Module is comprised of a heating/cooling chamber assembly that fits into an existing TherMoiré® oven chamber and a dual stage air cooler. The system accommodates evaluation of a viewing field as large as 200 mm x 200 mm (8 in. x 8 in.) and uses the fully integrated Surface Measurement operating software. The sample enclosure module comes with different sample support nozzle sizes to hold the samples under test. The free standing electronics enclosure houses the temperature controls, heating/cooling devices, over-temperature safety shut-off electronics, fusing and power distribution.

The Convective Module is designed to:ConvectiveModule

  • Cool samples down to sub-room temperatures as low as -50°C.
  • Use convective heat transfer to also attain reflow temperatures
  • Focus is on reliability style testing as reflow simulation in terms of heating rates and temperature uniformity is not on par with CRE6

The Convective Module is offered on the following equipment:
