56 PCB007 MAGAZINE I OCTOBER 2018 Goldman: Thank you. Now let's move on to the X-ray system. This is a Linear Z technology XRI machine? Evan Howard: Yes. The X-ray system will mea- sure panels as they come out of the post etch. It scans the panel, checking the accuracy of the post etch. GreenSource will be checking to see if the drill tools are getting dull or if anything is out of alignment. X-ray is the checks-and-bal- ances system before lamination. The next unit will be checking inner layers and aligning. It will look at the inside of the panel, then drill pinning holes based off where the inside of the panel is, accounting for the little bit of drift from the lamination process. It uses X-ray to look inside the panel, align ev- erything and then drill two holes that will align the panel on the drilling machines when they go into drilling and routing. Howard: In other words, it's correcting errors that have been introduced during earlier steps. Goldman: Which hopefully are small. Howard: Yes. Like everything else here, it's fully automated so it picks panels off a stack, brings them in, does the X-ray analysis and then takes them out. Goldman: And thee panels came here from from which manufacturing step? Howard: From the post-etch punch. E. Howard: The inner layers will come into the post etch, they'll get punched, then they'll come through here to be checked to make sure everything is where it's supposed to be. It then continues on to lay-up. Goldman: Is that what this next room is going to be, lay-up? E. Howard: Yes. These carts will load up with inner layers to be transported to the lay-up room. Goldman: Eventually transport will go straight through the wall, right? E. Howard: Yes, we already have the pass- through hole, it's just sealed off right now. Howard: This lay-up equipment here is com- ing from Burkle. Some of it came with the first phase: a hot press; a cold press; the loading system; and then the interconnecting conveyor together with lay-up and breakdown after the book is pressed. For the second phase a second hot press was added. The sequence of operation is like this. The loader goes back and forth in front of the machines and will take the load from the hot press, index down, put it in the cold press and then it will receive the next load from the lay- Figure 4: Burkle Process Technologies' lamination press.
