BTU HAS BEEN A LEADER IN IN-LINE THERMAL PROCESSING FOR OVER A HALF A CENTURY.
BTU’s products excel in processes where precise control of atmosphere and temperature are critical to product yield. With over 10,000 units shipped, service and support in over 30 countries, and manufacturing facilities on two continents BTU is the leading choice for global manufacturers.
The World’s Best Performing Reflow Ovens
Pyramax OvensBTU’s Pyramax family of high-throughput convection reflow ovens is widely recognized as the global standard of excellence for both printed circuit board solder reflow and for semiconductor packaging. The Pyramax features BTU’s exclusive closed loop convection control and process temperatures up to 400°C. For the most demanding applications Pyramax can provide O2 levels as low as 2ppm above source in the peak reflow zone.
Custom Furnaces: Made in the USA
BTU’s Controlled Atmosphere Furnace has the industry’s lowest Cost of Ownership and features process temperatures up to 1180°C. BTU’s automated thermal controls utilize segmented heaters to optimize thermal performance resulting in thermal uniformity better than +/-2°C. The system also features flexible atmosphere with Argon, Hydrogen, Nitrogen or forming gas available.

Voids affect the thermal characteristics and mechanical properties of a solder joint, thereby affecting the reliability of the solder interconnect. The automotive sector in particular is requiring the mitigation of solder voids in various electronic control modules to the minimum possible level. Earlier research efforts performed to decrease voids involved varying the reflow profile, paste deposit, paste alloy composition, stencil aperture, and thickness....

Over the past 30 years we have learned that lead has negative affects on the health of humans and seen strong legislation remove it from gasoline and paints. More recently, governments in Europe and Asia have set deadlines to remove lead from consumer electronic devices that use printed circuit boards. Currently, the ban is not being applied to high reliability applications such as military or medical devices, but we all know that will come someday soon. Likewise many believe that lead free solder is coming to wafer bump reflow and are beginning to make the transition....

Process engineers, who are seeking to achieve the most effective and reproducible thermal transfer process, look to today's forced convection ovens for applications such as flipchip, BGA, and lead-free soldering. A forced convection process to maximize thermal uniformity can be best accomplished by employing static pressure generation in what's known as "closed loop convection"....
