Royal Philips Electronics subsidiary Assembléon was showing its new high speed, high quality MCP screen printer at Productronica. Assembléon’s MCP screen printer has an innovative head design with variable attack angle printing, allowing it to maintain constant solder pressure independent of the stencil thickness. The single-head system also allows easy setup, and reduces maintenance by half. With a board cycle time as low as 11 seconds, it is the first stencil printer to match the high throughput of some of today’s high-volume pick & place machines. It is the first printer to match their high quality, too, by reducing defect per million (dpm) figures by up to 50%. The MCP has a flat-metal single-head squeegee to improve the speed and quality of printing. The squeegee’s variable angle print head significantly improves the repeatability of the paste deposition for 01005 components, even after a stencil cleaning. The squeegee maintains constant solder pressure and produces perfect solder shapes with stencil thickness down to 50 µm and half edging stencils with stencil steps of 30 to 50 µm. It is ideal for PCBs mixing 01005 (0.4 x 0.2 mm) types with larger component sizes.
