Make handling wet panels a thing of the past.
9624 IR Tack-Dry Oven
The 9624 IR Tack-Dry Oven is designed to quickly and efficiently tack-dry LPISM-coated Printed Circuit Boards. The unit consists of three individually controlled long-wave infrared
heater zones, a forced-air circulation system, and a conveyor to move the boards through the oven. This highly innovative technology, developed by Argus International, provides a
breakthrough in significantly reducing the tack-dry time of LPISM-coated PCBs. While convection-only ovens rely on air to transfer heat, the 9624 directly heats the board with IR
radiation and provides forced air circulation. This technique lowers the normal tack-dry time from 35-45 minutes to 3-4 minutes, that represents about a 1200% improvement in drying
efficiency!
Key Benefits
Traditional convection ovens use electric coils to heat the air; the air moves around and heats the coating; eventually the coating heats the substrate. Once the substrate gets hot enough to not heat-sink the coating, the coating dries from the outside.
The Argus IR Tack-Dry Oven employs 5 to 8 micron IR emitters that directly transmit energy to the most dense material, in this case the PCB. Because the air and coating are between the emitter and the PCB, some residual heating occurs, but the bulk of the energy is absorbed by the PCB. This means that the coating predominantly dries from the inside; that is, the junction between the PCB and the coating, thus increasing the drying rate while reducing skin formation and solvent retention. Forced air circulation in the 9624 then rapidly removes the evaporated solvent from the PCB surface.
Most LPISM manufacturers can supply coating materials that function well in the 9624. Ciba-Giegy, Coates, Dexter, Dynachem, Electra, Enthone, Grace, Lackwerke Peters, LeaRonal and Taiyo all produce LPISMs that have processed well in our laboratory evaluations. Potential customers are welcome to view the IR Tack-Dry Oven in operation, or to process sample boards in our Technical Service Laboratory.
The real benefit to acquiring the complete PC9000 LPISM Application System is that it allows the machines to be linked together so that LPISM application becomes a load-unload operation, without handling of wet boards. By placing equipment end to end, boards may be loaded at the entrance of the 9424B Spray Unit and removed at the exit of the 9624 Tack-Dry Oven just minutes later, fully coated and tack-dried.
With the PC9000 System, conveyor speeds of 4 feet per minute are realistic as are throughputs of up to 160 boards per hour for 18" x 24" samples, giving excellent production rates and genuine economy benefits.
Hot Air Leveler HAL5224
The HAL5224 Hot Air Solder Leveling System is designed to provide the highest quality solder leveling at high throughput rates while preserving the highest reliability and serviceability
standards available. Argus International has been designing, building and operating HASL systems for over a decade. The experience earned in a decade of dedication to engineering the
HASL process is evident by the high quality work produced.
Key Benefits
Stainless steel construction, integrated exhaust hood ducting, complete solder pot accessibility, high speed DC motor driven vertical arm, and fixed angle air knives are just a few of the features that are standard on the HAL5224.
Also available are a variety of 'quick-change' clamping mechanisms, remote control console and solder refinement systems. These features combine to produce 200 panels an hour average, 350 panels an hour maximum.
The clamp/knife arrangements most commonly used are the 'Pressure' and 'Pin' type. The 'Pressure' type clamp utilizes air pressure to apply a finger type force to the panel. The 'Pin' type clamp uses two tooling pins to 'hang' the board, and air pressure forces the board upward and locks it into place.
