Bruce, We had our system retro-fitted in the field. Here is the list of issues we are currently having with the system. Process Problem Items: 1. After installing new 350mm Wiper foil with metal strip glued on it, It worked for about a week and suddenly metal strip started peeling off from wiper foil. 2. End retainers (SKIS) has hard plastic piece glued on rubber piece. That plastic piece comes off from End retainer. So far, we have changed 4 End retainers. 3. In transfer head you have removable grid between paste cassette and conditioning chamber. This removable grid has `O' Ring . This O ring is larger than it's slot on removable grid. After placing O ring on the grid, when you invert the grid to fit on conditioning chamber O ring comes off. We had to glue the O ring in slot. 4. Removable grid on transfer head doesn't stay flat on conditioning chamber. After you tighten the screws, it becomes convex. 5. Holes on removable grid and holes on metal grid do not match. 6. Solder paste come out from ski area on stencil. 7. After print, it leaves streak of solder on stencil. 8. Lots of solder paste oozes out from gap between paste cassette and conditioning chamber. Making transfer head very messy. 9. After printing about 10 panels , next panel has insufficient solder. We prime 3 times solder paste at this time. But half of the time it still has insufficient solder on panel, at time we increase pneumatic pressure and it comes out O.K. 10. We do not have sensor for `Paste cassette empty.' The one we had was bad and service man took it with him saying they will mail us new one . it's about 3 weeks now, and we haven't heard anything about it from any one at DEK. 11. Paste cassette has 1.2kg solder paste in it and we can use only half of it, other half goes to waste. 12. We spent about $ 30,000.00 for Proflow compare to $300.00 for squeegee blades expecting much better print results, no solder paste waste, cutting down on stencil cleaning time and worry free printing . But that's not the case. As you can see it is quite a list. I believe that this system would be a good system, but there are a lot of bugs they need to work out. I think they were in too big of a hurry to release to market, and didn't work all the bugs out first. A Dek guy will be here Monday. Hope this helps.
