Spokane Valley, WA — ACE Production Technolo- gies announces the installation of a LTS200 lead tinning system at Murrietta Circuits, a high relia- bility, turnkey supplier of electronic manufactur- ing services. The KISS-LTS200 is an automated machine specifically intended for the hot solder dip lead tinning process, where aged components can be refurbished in preparation for re-qualification to high reliability standards. The LTS200 enables Murrietta to provide contract re-tinning services. With this system, lead-free, gold plated, and aged components can be re-tinned using the automated 2 solder pot system. The system brings consistency, repeatability,
and automation to the re-tinning process. The sys- tem 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 dedicated to applying virgin alloy. The system works in conjunction with program- mable controls to hold palletized components in a known position throughout the process. The pallet holder and pallets are versatile, min- imize change-over time, and accept virtually all devices including axials, connectors, and dualinline packages (DIPs). Re-tinning is increasingly used in the PCB assembly process for high-reliability customers due to obsolescence of many leaded compo- nents.
Carteret, NJ — Fujipoly has an- nounced availability of Sarcon® 50GR-Ae, an extremely soft 0.5mm thick thermal interface material. The gel-like sheet compound is de- signed to efficiently transfer heat from its source to a nearby heat sink. The unique physical properties of this material allow it to protect deli- cate board-level components as it fills unwanted air gaps and levels uneven surface.

immersed to a specific depth. The pallet then moves to the first solder (scavenging) pot, where leads are dipped into the solder alloy and scrubbed to remove the existing coating. The pallet 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 to create a homogenous intermetallic coating. When fitted with two lead free solder pots, the KISS-LTS200 can convert tin-lead components
to lead-free plated for RoHS compliance. Contact: ACE Production Technologies Inc.,
