The ULTIMA Series Selective Soldering and Fluxing Machines represent a new solution to soldering through-hole components and connectors to surface mount and mixed technology PCBs. Selective soldering eliminates hand soldering and custom wave soldering fixtures, and reduces the risk of component overheating and board damage. The ULTIMA TR2 Selective Soldering System is unique in that a high-precision X-, Y-, and Z-axis drive mechanism moves the PCB rather than the solder pot, resulting in a compact, bench-top design that is fast, accurate, and easy to maintain. Unlike systems that squeeze soldering and fluxing functions into a single unit, the TR2, working in unison with an SP Selective Fluxing System, improves throughput and isolates soldering operations from flux overspray and residue. Program data from the TR2, easily generated on-line, off-line, via Gerber data, or a scanned image of the PCB, can also be used to quickly generate precise, localized fluxing programs for the SP.
