In its basic format, the Prodex is configured with a single solder bath. In its Duplex guise, the machine can be configured with twin adjacent solder baths on independent Z axis drives. This achieves increased production flexibility by permitting use of two different nozzle tip sizes which can be allocated as process requirements dictate within any particular area on a PCB. All Prodex configurations can be offered with optional automatic heated solder bath change stations. Using this system the non-operational solder bath and pump system can be stationed at one of the two optional heated park positions located at either side of the main machine. This heated station, maintains the correct solder temperature within the bath that is idle so that when changeover occurs, the replacement bath can resume immediate production. A single automatic solder bath change station is identified as a PLUS configuration, whilst twin stations (located at both sides of the machine) are identified as PLUS PLUS configurations. On this basis Duplex machines with the PLUS PLUS identity will operate with 4 individual solder bath and pump systems. The Prodex series is controlled by a PC, through PillarCOMM, a Windows® based ‘Point & Click’ interface with a PCB image display. Additionally our optional PillarPAD offline programming package allows the operator to produce programs independently from the machine using Gerber data.
