Have been using blades for many years. Started using the MPM rheopump system after looking at the DEK pro-flo and multi-system "Paste Puck" device. PROS: very fast printing speed- even with fine-pitch, excellent aperture fill, phenomenal repeatability with little-to-no operator intervention for many hours at a time, and almost no stencil cleanup post-production (results using new MPM printer w/vacuum underwipe). Overall, much less downtime, slightly better quality. CONS: very delicate installation and part-replacing operations (operator training issue), only can use certain pastes (at this time), new tooling setup and equipment necessary (operator training issue), and, of coarse, cost. Overall, less adaptability, increased setup time and training.
Honestly, as a contract manufacturer, we donít get much use of the system. We are concerned with small batches and minimizing changeover times. We use several different pastes. Our gains from rheopump use are minimal. OEMís trying to maximize throughput on continuous production lines would benefit greatly from itís time savings.
