||Benecia, CA — Equipment Services, LLC announced a new line of ESE US-X Series solder paste printers to the North American PCB assembly market. The Korean built SMT screen printers feature standard 2-D solder-paste inspection. For accuracy, all major components of the ESE solder printers are controlled by high-precision servo motors instead of stepping motors and belts. The ESE printing table is supported by four ball screws and three LM guides allowing even squeegee pressure across the table width which results in a repeatability of 12.5 microns. The printing table conveyor system has adjustable front and rear rails to position the PCB directly over the center of the table for paste printing components down to 01005 (0402 metric) and pitches to 0.012 in. (0.3mm). The printers' programmable five-stage snap-off function contributes to its high printing quality. The plunger mechanism enables quick stencil changeover and the conveyor system features a patented one-touch width adjustment that uses LM guides instead of ball screws. A Cognex® vision system features an up-down CCD camera and four separate LED rings for accurate recognition of PCB and stencil fiducial marks and real-time 2-D solder paste inspection. A closed-loop feedback option allows automatic calibration of printing registration and adjustment of the stencil spray cleaning system by a downstream solder paste inspection system. The ESE stencil spray cleaning system features programmable wet, dry, vacuum, and air-blow modes, for fast, thorough cleaning. The solvent tank is conveniently located on the side of the machine, eliminating the need to stop production to refill. Other features include a mechanism to prevent the edges of the cleaning paper from fraying and a programmable paper saver. The ESE Windows XP interface allows PCB programming and easy access to maintenance and manufacturing data.
