BTU INTERNATIONAL

ABOUT BTU  

BTU International is a market-leading supplier of advanced thermal processing equipment to the electronics manufacturing and energy generation markets. BTU manufactures reflow furnaces for printed circuit board assembly as well as for wafer-level packaging and die-level packaging. BTU also provides thermal process equipment for the solar cell, fuel cell and nuclear fuel industries. BTU, with headquarters in North Billerica, MA, operates worldwide with direct sales and service offices in the USA, Asia and Europe.

PRODUCT OVERVIEW  

BTU prides itself on their ability to analyze a complex set of thermal requirements and translate them into a cost effective manufacturing solution. Their customers require high throughput, high yield and highly reliable advanced thermal processing systems with tightly controlled temperature and atmosphere parameters. BTU’s engineering expertise has allowed us to serve our global customers and provide solutions for a vast array of thermal applications.

FAST FIRE  

NUCLEAR FUEL  

FAST FIRE
Thick Film metallization is used to construct electrical circuits onto ceramic or metal substrates for automotive electronics, microelectronics packaging, resistive heaters, and passive circuit applications. In the process, a series of metal traces and up to 35 dielectric layers are created on the substrate using sintering and drying processes.

NUCLEAR FUEL
Typical applications include high temperature uranium and gadolinium processing for power generation. BTU offers its patented Walking Beam and TCA furnaces. Applications include reduction, oxidation and firing.

FUEL CELLS  

DIFFUSION  

FUEL CELLS
Solid Oxide Fuel Cells are precision electrochemical reactors. Thermal uniformity in the firing process is required to achieve electrical and chemical reaction reliability. For the high temperature firing of solid oxide cells, BTU offers the Convection Batch Furnace and the Continuous Pusher Furnace that achieves the needed firing control to yield improved process and product uniformity.

DIFFUSION FURNACES
BTU’s quartz lined furnaces have been optimized for phosphorus diffusion, in-line processing of solar cells. Our unique fused quartz lined process chamber design, thermal uniformity and atmosphere control, combine into a high throughput, in-line solution. The quartz lining creates a metal-free processing tunnel design which eliminates the reaction with phosphoric acid.

ANTI-REFLECTIVE COATING  

CONTACT DRYING/FIRING AND METALLIZATION  

AR-COATING
BTU’s TCD Series furnaces have been optimized for the deposition of TiO2 anti-reflective coating. This is accomplished by the use of the Atmospheric Chemical Vapor Deposition (APCVD) process. The system is available in 1 or 2 head configurations depending on throughput requirements.

RTC
BTU is pleased to offer the entire line of PV and PVD series furnaces from Radiant Technology Corporation. RTC, the first name in infrared furnace solutions, has incorporated 35 years of experience and know-how into this Rapid Thermal Processing line of furnaces. Specifically designed for solar cell applications.

CONVECTION DRYERS  

DRYERS
BTU’s radiant dryers operate at temperatures up to 300°C. Often used for drying inks before firing thick-and thin film circuits, they are also a particularly cost-effective choice for most curing applications. The dryers are available in a number of belt widths and lengths, and in both stand alone and in line configurations.
