LA-306:  3-Zone, 15 cm, (6-inch) belt
Single phase 1000 deg C IR furnace for tight temperature control in a tiny footprint for production and lab.  Updated for 2014, the ever popular LA-306 models include our latest Discrete Digital Control system with our new closed-loop belt speed control.

LA-309P:  3-Zone, 24 cm, (9.5-inch) belt
Brand new for 2014, the LA-309P provides large furnace processing power in a high-quality cost-effective compact furnace.  The LA-309P is features the standard LA-309 furnace internals installed in an expanded LA-306 frame.  Like the LA-306, the LA-309P uses our latest Discrete Digital Control system with closed-loop belt speed control.

LA-309: 3 to 4-Zone, 24 cm, (9.5") belt
The LA-309 furnace is a powerful and versatile 3- or 4-zone computer controlled furnace.  LA-309 and LA-309P both include a transition tunnel exhaust stack for balancing process gas flow.
LA-series furnaces are used for experimental, prototype or low volume processing and specialty production applications where rapid heat rise in a controlled process atmosphere in a small footprint is of particular interest. Its flexibility, process precision, temperature range, and controlled atmosphere capabilities is similar to many of our larger models.

Clean air compatible to Class 1000, the LA-309 can process substrates, wafers, PCBs, metal, ceramic, or glass parts for VOC burnout, thick film firing -- including solar cell firing, semiconductor package sealing: solder lid seal, glass seal, low oxygen solder seal (<20ppmv), glass seal, epoxy die attach, polymer curing, reflow soldering, and precious metals and alloy brazing and annealing.
Semiconductor Packaging

SMD-Series IR Furnace
SMD-series infrared furnaces for higher production yield and throughput and feature start-up often in less than 30 minutes for temperature profiles up to 1000°C.

Tested against convention furnace technology, the SMD-series furnaces offer faster setup and stabilization time; repeatable profiles; no degrade of seal process; lower internal cavity moisture content and comparable hermetic performance; lowest ppm defect rates; and superior temperature uniformity.

Also 90% belt edge conveyor load efficiency.  Inert atmosphere for fine pitch solder pastes.  Diffuse near and medium IR heating efficiency without color selectivity.

Electronic industry semiconductor packaging, frame attach, die attach and sealing applications. Choose Air for low cost; Nitrogen (max 500 ppm oxygen) reduces board browning and flux charring for easier cleaning; or Nitorgen (max 5 ppm Oxygen) for 40-60% faster processing speeds, lower defect rates, and improved secondary soldering yields, ideal for high volume critical applications. 
Also used for ceramic and glass epoxy applications and a variety of production processes including
    ▪  Curing polymer thick film materials
    ▪  Epoxy potting compounds
    ▪  Nonmenclature and legend inks
    ▪  Conformal coatings
    ▪  Bonding epoxys or encapsulating epoxys on IC's
    ▪   Process heat shrink tubing
    ▪  Bake photo resist on silicon wafers
    ▪  Drying thick film pastes.
Thick Film Process Furnace
TF-Series IR Furnace html

Updated, with new DDC control system. Fast efficient thick film production infrared furnaces.  Capable of 1000°C, these units utilize high level near infrared radiation to rapidly and accurately fire resistors, conductors and dielectrics in a controlled clean, dry atmosphere. The furnaces are designed to cycle on a daily or more frequent basis.  They will stabilize at 1000 deg C from a cold start in under 20 minutes.  Major profile changes can be accomplished in minutes, allowing the furnace to be regularly used for a variety of processes. 

Production rates of up to 23,000 square inches per hour (16 ipm) can be achieved, with still higher rates for some conductors and dielectrics. 
Designed for 280-1000°C volume production of noble metal thick film products, metal, ceramic and glass inks screen-printed on a variety of substrates for production of surface mount devices, hybrid integrated circuits and sensors including  semiconductor package sealing:  solder lid seal, glass seal, low oxygen solder seal (<20ppmv), glass seal, epoxy die attach and other electronic devices.

The energy-rich, radiant environment allows all thick film materials to be processed very rapidly.  Resistors are processed at total profile times of 12-15 minutes while conductors and dielectrics can be fired in as little as 10 minutes.  This environment affords tighter distribution of process parts and also gives the processor the ability to cofire multilayers up to 300µm thick.
Seal Production Furnaces

S-Series IR Furnace

Fast efficient production infrared furnace, the S-series furnaces offer high production yield and throughput and feature start-up often in less than 30 minutes, precise and repeatable zone temperature control, temperature profiles up to 1000°C, and controlled-atmosphere capability of 1-5 ppm above incoming gas purity.  The S-Series Infrared Furnaces utilize high intensity heat to achieve exacting temperature profiles, with rapid heat rise and no overshoot.  Two to 12-Zone systems available.Ideal for many high-temperature semiconductor and thick-film processing.  The rapid heat rise of these furnaces is of particular advantage in the final lid sealing or die attach process since the semi-conductor is not exposed to prolonged high temperature. In lead frame attachment, there is no contact with the part to cause distortion in the frame. All leads remain planar which greatly facilitates subsequent automatic wire bonding steps.

 AG-Series IR Furnace
Infrared furnace temperatures up to 1000°C, multistage temperature profiles, rapid removal of volatiles with multiple intermediate exhausts, inline drying and firing, multiple atmospheres with gas barriers, clean room compatible. Two to 12-Zone systems available.Silver-glass die attach, CERDIP and similar processes requiring multi-stage temperature profiles and rapid removal of volatiles. These capabilities are facilitated by the use of multiple intermediate exhaust stacks. Ideal for single and two stage silver-glass die attach profiles, as well as solar-cell and green tape drying and firing sequences.
Solar Cell Furnaces
S-Series IR Furnace

Fast eficient production infrared furnace.  SC-series furnaces offer high production yield and throughput, feature start-up often in less than 30 minutes, precise and repeatable zone temperature control, temperature profiles up to 1000°C, and controlled-atmosphere capability of 1-5 ppm above incoming gas purity.  The SC-Series Solar Cell furnace can be combined with an integral dryer in the SCD-Series Solar Cell system. High-temperature photovoltaic applications.  The rapid heat rise of these furnaces is of particular advantage in the final  process.  Order with a dryer as an option. 


All standard models include an industrial rack mounted computer with LCD  screen, full size keyboard interface and Ethernet high-speed network connections to facilitate view and control of the furnace by managers and process engineers from any location. Four (4) local USB ports are provided, convenient for connecting a furnace profiler and jump drive storage devices.
