The ACE KISS-LTS200 Lead Tinning System
The KISS-LTS200 system utilizes a central fluxing station with 2 solder pots, one to each side of the fluxing station. One solder pot is typically dedicated to flushing off the original coating (or plating) while the second solder pot is usually dedicated to applying "virgin" alloy for the final coating. The system works in conjunction with programmable controls that hold palletized components in a known position throughout the process. The pallet holder and pallets are highly versatile, designed to accept virtually all leaded devices with minimal change-over time, including axials, connectors, DIPs, and QFPs. Components first move to the central flux station, where the component leads are immersed to a specific depth. The pallet then moves to the first solder pot (scavenging pot), where the leads are dipped into the solder alloy and "scrubbed" to remove the existing coating. The pallet then returns to the flux station, where the component leads are refluxed before moving to the second solder pot for the final dip of fresh alloy, thus creating a homogenous intermetalic coating. When fitted with two "lead free" solder pots, the KISS-LTS200 can also be utilized to convert tin-lead plated components to lead-free plated for RoHS compliance. In this process, one solder pot is used to dissolve the original plating into the sacrificial alloy of the first pot. The component leads are then re-fluxed and dipped into the second 2nd "virgin alloy" solder pot for the final lead-free coating. This system also permits simple modifications to add programmable routines such as "agitate in the solder" to help remove the original coating. Customers can also specify and control "withdrawal rate" from the final solder bath to increase the solder thickness and enhance the quality of the final lead finish. QFP Lead TinningACE offers a LTS-QFP specific to tinning fine pitch QFPs and other gull wing leaded components. The LTS-QFP is configured with an articulating vacuum pick-up tip and vision centering to aquire and process the most delicate and expensive components. ACE has successfully processed gold leaded devices with lead pitch centers of .020" (.5mm) and toe to toe of 3" (75mm). This is new so call for more information.
