92 PCB007 MAGAZINE I OCTOBER 2018 Matties: It sounds like a tricky process overall. Zeller: Yes, it will be due to unique set-up of each customer. It will be an ongoing process with close communication and meetings to get the final version. Matties: Will the transport system be running very thin materials also? Zeller: Yes, all the machines are laid out for 1-mil cores. On the handling units we don't use any mechanical centering anymore. All the centering and aligning process of the panels is done with optical components to avoid any damage to the thin or sensitive products. In ad- dition to the thin core set-up we also have all handling units fitted to handle heavy outer lay- er panels with a weight of over 3.0 kg per pan- el. The switch between thin core and heavy panel set-up is done automatically. Matties: That's sounds unique. Are there many companies trying for that mix in the same fac- tory? Zeller: No, this is not very typical, but we have this set-up for the whole project, so we can switch between thin cores and heavy panels. It's all done automatically and based on DMC code and data. We don't need an operator to do it. We know what kind of panels are in pro- cess and as soon as we read the DMC code on the panel we will automatically set up the han- dling units for these products. Holden: How does the new equipment pro- cess differ from the first phase in terms of wa- ter conservation for rinsing, ventilation, and the temperature of the process to create more evaporation? Zeller: We worked very closely with Alex on water conservation. All the rinses are set up with what we call "one plus four" or "one plus three." The first stage is a drag-out stage, which is separated from the other cascades. Thus, we concentrate the first stage, and then the follow- ing stages are standard cascading set-up. With this set-up the water usage is greatly reduced and in line with Alex's expectations. Figure 6: Close-up of an AWP material handler in action at GreenSource Fabrication.
