Automatic screen printer for working with PCBs up to 650x510 mm
- The printing-table conveyor system does not have a fixed front or rear rail as with conventional printers. Instead, adjustable front and rear rails position the PCB directly over the center of the table, allowing consistent, high-precision paste printing for components down to 01005 (0402 metric) and pitches to 0.012 in (0.3 mm).
- ESE’s adjustable stencil rails eliminate the need for expensive stencil adapters that are time-consuming to set up and can get lost, bent or damaged. An easy-to-use plunger mechanism enables quick changeover of stencils, increasing productivity.
- The 3 stages of incoming, Middle outgoing conveyor system features Automatic width adjustment for quick, trouble-free operation.
- ESE vision system features an up/down CCD camera and four separate LED rings—three for the PCB and one for the stencil—for simultaneous recognition of PCB and stencil fiducial marks, as well as automatic 2-D paste inspection. The highly accurate system recognizes any type of mark, including custom marks that can be created by the user.
- The print head, which is controlled by high-precision servo motors and LM guides, features a programmable five-stage snap-off function, resulting in superior printing quality.
- The under-stencil cleaning system features programmable wet, dry, air-blow and vacuum modes, for fast, thorough cleaning. The solvent tank is conveniently located on the side of the machine, eliminating the need to stop the machine for refilling. Other features include a mechanism to prevent the edges of the cleaning paper from fraying and a programmable paper saver.
- The user-friendly ESE software, which runs on the familiar Windows 7 (or Windows 10) operating system, allows efficient programming of PCBs and easy access to maintenance and manufacturing data.
