Pyramax Vacuum
VACUUM REFLOW OVEN FOR HIGH-VOLUME
- Thermal Uniformity +/-2°C
- Superior Profile Control
- Full MES Integration

The Pyramax Vacuum reflow oven has been designed with the requirements of large EMS/high-volume automotive customers in mind. The unit is configured with 10 zones of closed loop convection heating and a maximum production width of 457 x 457mm (18 x 18 inches) inches under vacuum operation. Nitrogen atmosphere capable, the Pyramax Vacuum reflow oven offers a maximum process temperature of 350° C. The unit features integrated controls with BTU’s proprietary Wincon™ windows-based control system and full integration with factory MES/Industry 4.0, including vacuum parameters. Existing Pyramax customers can easily transfer their process to the new Pyramax Vacuum reflow oven.

Pyramax TrueFlat
NEW REFLOW OVEN TECHNOLOGY FOR SUBSTRATE
- Low maintenance
- No vacuum pump
- Superior thermal


Built on the industry-leading Pyramax platform, TrueFlat is a unique reflow oven configuration to stop substrate warpage.Bottom chamber of a Pyramax TrueFlat convection reflow oven. Designed for substrate thicknesses of 0.15 to 0.30mm, TrueFlat technology ends die tilt. The result is consistent and repeatable flatness, and superior thermal uniformity due to the Pyramax’s closed-loop convection heating.
The new Pyramax with TrueFlat technology does not impact reflow oven footprint, making it easy to transition from existing reflow processes. Easy to maintain with no vacuum pump, the system offers simple operation and full integration with BTU’s proprietary WINCON™ Windows-based software including factory host/MES interface for Industry 4.0 compliance.

Belt Furnaces with Precise Atmosphere and Temperature Control

BTU’s custom high-temperature belt furnaces have been manufactured in Massachusetts for over six decades with ISO 9001 quality certification safeguarding that each unit is subject to exacting build and test criteria.
BELT FURNACES WITH PRECISE ATMOSPHERE AND TEMPERATURE CONTROL
BTU’s custom belt furnaces come in two basic configurations: muffle or muffle-less.
A muffle furnace is typically used in applications where control of temperature and atmosphere are of utmost concern – or for special process atmospheres such as Hydrogen.
A muffle-less furnace has operational advantages for use cases where the furnace will be heated up and cooled down frequently while still providing precise control of temperature and atmosphere.
The features and characteristics of the belt furnaces that are usually customized based on the customer’s application and throughput needs are:
*Overall furnace length
*Maximum process temperature
*Process chamber width and height (clearance)
*Number of heated zones
*Cooling length and zones
*Belt loading
*Atmosphere capabilities including control and safety considerations
