Transition Automation has introduced an Electronic Self-Cleaning Metal Squeegee System. This system provides a solution to the problem of solder paste dripping and clogging onto squeegees, with resulting fast dry-out of the paste, which has long been a major problem in SMT solder paste printing. The self-cleaning system also improves and simplifies maintenance of the printer area, with less contamination of floors and surrounding SMT printer components when squeegees are removed from the printing machine.
Electronic controls give users hands-off, automatic squeegee cleaning of solder paste (including lead-free solder paste) from squeegees. The new system is completely self-contained and self-actuating, and provides user settings for the number of clean iterations per print. The system incorporates an 'odometer' which counts the number of prints the squeegee has experienced, and allows the user to set a limit, after which a red light will flash indicating that the limit has been reached. This counting and limit function is useful for quality control to ensure that old squeegees are checked for quality and has been awarded a US Patent.
The sqeegees are available for EKRA, DEK, MPM, and Panasonic printers, and retrofits for other printer models are available on request.

Editor's Choice Manufacturing / Production Technology, Hardware & Services
Dross formation is an inevitable consequence of wave soldering. It occurs when molten solder comes into contact with oxygen, forming metal oxides that float on the surface of the solder bath. Over time, this oxidation byproduct accumulates and must be removed to maintain solder quality and process consistency.
