| Digital Hot Plate | ||||
 |
Let’s begin with the Digital Hot Plate. The Hot Plate incorporates microcomputer circuitry which controls key parameters. The system is very simple to operate, with temperature programmable from room temperature to 350°C in one-degree increments. The temperature is also measured by K-type thermocouple, complete with an easy calibration procedure. Precision machined 8” aluminum plates are used to achieve even temperature and flatness for the most exacting results. Suggested applications include:

| Falcon 5C | ||

The Falcon 5C solder reflow oven combines bottom-up conduction and top-down convection technology with precise calibration of temperature and purity of atmosphere for ultimate control of your solder or curing process. It is a tabletop system intended for production runs of moderate product sizes and is manually operated. Maximum substrate size is 5” x 5.75”. The Falcon 5C is a 7 zone system capable of temperatures up to 400°C featuring a liquid cooled load platform, four bottom conduction/top convection heat zones, one bottom conduction/top convection liquid cooled zone, and a liquid cooled offload platform. Each heated zone has independent set point controls and gas flow controls to ensure consistent and precise temperatures for greater profile flexibility. The internal liquid cooled zone ensures a process cool down in an inert atmosphere prior to the product exiting onto the offload platform. Parts are transported through the system using sweeper bars that operate in a “dwell” or timed delay mode. The system may be operated with air, nitrogen, or forming gas. The inert gas flow enters the reflow chamber through small orifices in the top heated platens and exits the sides to prevent contamination of adjoining zones and completely eliminate flux buildup. In addition to heating the inert gas, the top platens also contribute significant radiant heat to the reflow process and are easily adjusted to minimize the opening of the reflow chamber, down to as low as 1/4", thus conserving inert gas consumption while maintaining the desired oxygen level in the chamber. If the need is to process a large high mass assembly the top platens can easily be raised to accommodate a part that is over 4” tall. Curtains on each end of the chamber will assist in lowering the O2 ppm when tall parts are processed. Suggested applications include:

The patented UP2000 solder reflow oven features state of the art technological advancements designed to provide ultimate control of your solder reflow process. The furnace combines bottom-up conduction and convection with top-down convection, precise calibration of temperature and purity of atmosphere. The system is available in 2 configurations, either a manually loaded stand-alone unit or an automated version which utilizes robotics, sensors and SMEMA interface connection to link into a line with other automated assembly machines. The UP2000 is a 7 zone system capable of temperatures up to 400°C featuring a liquid-cooled loading platform, 4 top and bottom conduction + convection heat zones, 1 top and bottom conduction + convection liquid-cooled zone and a liquid cooled offload platform. Each top and bottom heated zone has independent set point controls and gas flow controls to ensure consistent and precise temperatures for greater profile flexibility. The internal liquid-cooled zone ensures a process cool-down in an inert atmosphere prior to the product exiting onto the offload platform. Parts are transported through the system using sweeper bars that operate in the “dwell” mode allowing for adjustable cycle times capable of less than 10 seconds per cycle. The system may be operated with air, nitrogen or forming gas. The inert gas enters the reflow chamber through small orifices in the top and bottom heated platens and exits the sides to prevent contamination of adjoining zones and completely eliminate flux buildup. In addition to the heated inert gas, the top platens also contribute significant radiant heat to the reflow process and are easily adjusted to minimize the opening of the reflow chamber to as low as ¼”, thus conserving inert gas consumption while maintaining the desired oxygen level in the chamber. Maximum substrate size is 3.9” x 12”. Suggested applications include:

Similar to the UP 2000 in format, the UP 4000 does have some significant differences as well. The UP4000 is a 12 zone system featuring a liquid cooled loading platform, 7 top and bottom conduction + convection heat zones, 3 top and bottom conduction + convection liquid cooled zones and a liquid cooled offload platform. All zones have independent set point controls and gas flow controls, and like the UP2000 utilizes internal liquid cooled zones for process cool down in an inert atmosphere. Parts are transported through the system utilizing sweeper bars that operate in a “dwell” mode. The system may be operated with air, nitrogen or forming gas. Maximum substrate size is 3.9” x 12”. Because of the 7 heat to 3 cool zone ratio this is an ideal system for high volume and high mass part processes. Suggested applications include:

| Falcon 8500 | ||||
 |
Incorporating Sikama’s unique “thermal technology” based on conduction heating in combination with forced thermal convection, the Falcon 8500 has five heat zones. Each system includes automatic load and unload buffers with appropriate sensors providing SMEMA interface connection to link with Sikama ICS 412 Flux coater or other automated production equipment. Maximum substrate size is 8” x 11. Prior to entering the heated zones, the temperature of the substrates is stabilized in the liquid-cooled load zone. Each heated zone has individual set point controls and gas flow controls that maintain platen temperature to within +/- 2C to ensure consistent and precise temperatures for reliable, repeatable profiles. The gas is introduced through tiny perforations in the conduction heating platens and enters the reflow chamber at the same temperature as the platens. The internal liquid cooled zone ensures a process cool-down in an inert atmosphere. Further cooling of the substrates is accomplished as the product exits into the liquid cooled offload zone. The system can be supplied to operate left-to-right or right-to-left, but direction must be specified when ordering. The system can be interfaced with a computer, customer supplied, for storing profiles, monitoring of individual heat zone temperatures as well as dwell time controls and remote operation. A tray to accommodate a laptop computer is supplied and optional Windows based software is available. Optional walking beam transportation is also available. Suggested Falcon 8500 applications include:

The Falcon 1200 is a multi-purpose furnace capable of temperatures up to 400°C that can be used as a reflow solder system as well as for epoxy curing applications. Utilizing conduction heating as well as forced thermal convection, the Falcon 1200 contains 1 load zone, 7 heat zones and 2 cooling zones and includes automatic load and unload buffers with appropriate sensors providing SMEMA interface connection to link with the Falcon ICS 412 Flux Coater and automated production lines. The system may be operated air, nitrogen, or forming gas. Prior to entering the heated zones, the temperature of the substrate is stabilized in the liquid-cooled load zone. Each heated zone has individual set point controls and gas flow controls that maintain platen temperature to within +/- 2C. The gas is introduced into the reflow chamber through tiny perforations in the conduction heating platens and enters the chamber at the same temperature set for each zone. The internal liquid cooled zone ensures a process cool down in an inert atmosphere. Further cooling is accomplished as the product exits into the liquid cooled offload zone. Parts are transported through the system in the same manner as other machines, utilizing sweeper bars that can operate in the “dwell” mode. Optional walking beam transportation is available at no additional cost. The Falcon 1200 can be interfaced with a customer-supplied computer using optional Sikama software for storing profiles, monitoring of individual heat zone temperatures, as well as time controls and remote operation.
