The PC4700 and PC4800 Series fusing systems were designed to reflow double sided and low mass multilayer circuit boards. The system consists of one temperature-controlled long-wave IR emitting zone for a saturating preheat (this feature on PC4800 system only), and one short-wave IR emitting zone with independent upper/lower lamp control. This patented fusing technique provides a wider process window than all lamp systems. The preheat and reflow zone emitters are selected specifically for preheat and reflow purposes, respectively.

Key Benefits:

The control system provides highly accurate temperature and lamp power control. Temperature control is within 2 degrees Celsius. Lamp power control is within 1% of full power. Conveyor speed is controlled to within 1% of full speed.

PC4800 Service Specifications

The importance of starting a process with a clean surface cannot be stressed enough. This system provides excellent board cleanliness prior to fusing and/or HASL processes. To maintain machine cleanliness all controls are mounted on a NEMA-rated control console that may be placed up to 10 feet from the machine.

Postcleaner Injection System: Provides the ability to inject post cleaning chemistry directly into the recirculating spray manifold. Post cleaning solutions can significantly improve the effectiveness of the PC3000.

Antifoam Injection System: Provides the ability to inject antifoam solution into the PC3000 drain. The antifoam solution normally is used when either the flux or the post cleaning solution generates large amounts of foam.

Turbo Air Knife Drying: Adds increased drying capability by employing high velocity air to remove puddle water on exit from the PC3000. This option makes the IR drying more effective by reducing drying requirements.

Recirculating Sump Heating: Provides a sump heating system. Flux residues are more easily removed with modest increases in spray temperature.
