Stencil printer offers crisp definition affordably

The AP430’s SMEMA-compatible conveyor and PCB holder accommodate boards with print areas up to a maximum of 17.75x13.75”, while the quick-change stencil clamp with programmable stopper accepts large frames up to 29x29”. High-precision ballscrew drives work in unison with the CCD alignment camera to provide X, Y, and Ɵ axis correction for ultra-precise PCB-to-stencil registration within ±0.0003”. In the Z-axis, independent ballscrew control of the PCB height and four-corner ballscrew positioning of the stencil frame ensure coplanarity of the stencil and board surface

After printing, these same four ballscrews maintain perpendicular and uniform separation of the stencil from the PCB at a programmable speed that guarantees ultra-crisp print definition for the particular application. Stroke, speed, and pressure of the AP430’s dual squeegees are also programmable. All these features combined contribute to a ±0.001” print accuracy that is more than adequate for SMT’s most challenging solder paste printing tasks.

To maintain quality throughout entire production runs in small aperture printing applications, a clean stencil is essential. For this reason, automatic stencil wiping is a feature included on every AP430 system. The wiper can be run in either wet or dry mode, with or without vacuum, and variables such as interval, paper feed and solvent injection are all programmable.

For a limited time, Manncorp is offering free, on-site installation and training on the AP430, which is also backed by a one year warranty on parts and labour. The purchase of a complete turnkey system (printer, pick and place, and reflow system) automatically extends the standard warranty to two years.
