Proven Reflow with Next-Gen Flux Management from BTU at APEX

NORTH BILLERICA, Mass., December 2021 — BTU International, Inc., a leading supplier of advanced thermal processing equipment for the electronics manufacturing market, today announced plans to exhibit during the 2022 IPC APEX EXPO, scheduled to take place Jan. 25-27, 2022 at the San Diego Convention Center in California. The company will showcase its Aqua Scrub™ Flux Management Technology and a PYRAMAX™ 125N reflow oven in Booth #1601.

Reflow oven flux management“We’ve seen widespread adoption of our new Aqua Scrub technology both with new Pyramax reflow ovens and upgrades to existing lines,” said Rob DiMatteo, General Manager of BTU International.  “The benefit in avoiding maintenance related downtime, especially for high volume lines, is really compelling.   There are still many more customers who can benefit from this technology and we’re happy to share it at APEX this year,” added DiMatteo.

Aqua Scrub Technology is BTU’s next-generation solder reflow flux management system. The patent-pending design uses an aqueous-based scrubber technology compatible with most known paste and flux types. The flux and solution are automatically contained and packaged for disposal.

The Aqua Scrub is purpose-built as a stand-alone system that can be easily retrofitted on PYRAMAX™ reflow ovens already in the field as well as being configured on new PYRAMAX ovens. This self-contained unit mounts on the back side of the oven to minimize the impact on oven operation and factory floor space.The Aqua Scrub has a very attractive cost of ownership and is designed to decrease operational cost by 4X compared to traditional condensation systems. Reduction in cost can be attributed to reduced downtime, labor and disposal costs.

The PYRAMAX 125 Nitrogen convection reflow oven has 10 heated zones for the SMT assembly line. This quality SMD reflow convection oven has perfect heating and cooling performance.
