20 PCB007 MAGAZINE I AUGUST 2023 how to maintain them. ey have a lot more ownership of that, even more than our mainte- nance team on a day-to-day basis. All our lines are integrated. One of the cool things we're doing here is using SEL equip- ment to collect real-time process data. We have a product called RTAC (Real-Time Auto- mation Controller) that communicates with PLCs, and we use that to get information using a range of industrial communication protocols. Using our soware-defined network, we con- trol all network traffic between MES, RTAC, and equipment. is increases the security between our systems and our equipment in case there's ever a security vulnerability with piece of equipment. What sort of volume are you producing? Hendrickson: While we have relatively high volume, we also have a lot of part numbers. I believe that 20% of our part numbers are 80–90% of our volume, which means 80% of our part numbers are lower volume. is requires us to have flexibility to change over and run the lower-volume jobs. For example, the drill room features a number of Schmoll single-spindle drill machines, which load and unload through automation. What sort of tolerances and line spacing are you trying to achieve? Hendrickson: e traces and spaces we're tar- geting right now are about 2.5 mil traces and 3 mil spaces, especially for outer layers. We're also using pinless lamination to help get tighter registration there. We also have an Impex Pro X3 machine that will scan a panel with 150,000 holes in 20 seconds. It provides us the SPC data for diameter and location. It's been an instrumental tool in qualifying Schmoll's Modul drills in a Cube line shown with optional automation.
