DDM Novastar Awarded Custom Pick-and-Place Machine Order


Reading time ( words)

DDM Novastar, a U.S. manufacturer of SMT and PCB assembly equipment, was awarded an order to design, build and commission a unique reel-to-reel in-line PCB assembly line. The customer, a large international medical device manufacturer, sought a company that could take a reel of substrate, populate it with BGA logic circuits, reflow them in place, and finish by rolling the completed strip onto an outboarding reel interlined with paper.

Solder paste is dispensed in the first step of the process, then an automatic vision system verifies its accuracy. Next, as the strip proceeds without stopping, an in-line pick-and-place machine positions a micro BGA circuit, via various loop controls, from a tape feeder onto the strip, with accuracy of +/- .0005”. Another vision system verifies its position. The strip then travels through a continuous oven to reflow the solder, and passes through a cooling unit to return the assembly to ambient temperature. The next station performs an electrical test of the final circuit on the fly, and the strip is then rolled into a final coil, to be moved to additional processing stations.

When complete, a single reel contains nearly 15,000 micro BGA circuits, each of which is ultimately used to provide feedback on a single medical device.

Commented Bob Voigt, DDM Novastar’s application engineer, “The customer came to us because of our skills at making non-standard assembly equipment, and quite frankly, they’ve been very happy with the end result. For customers looking for some level of customization, DDM has vertically integrated design, engineering, software and manufacturing capabilities to get the job done, soup to nuts.”

What’s Driving AOI Innovation and Collaboration?

03/25/2020 | Brent Fischthal, Koh Young America
When we look at the optical inspection market growth trajectory, we can see how process challenges helped create innovations. For example, solder paste inspection (SPI) has undergone a shift from 2D to 3D because the 2D inspection technologies manufacturers traditionally used to collect solder deposit images could not solve shadowing problems. Thus, companies developed 3D SPI to capture the printed solder paste height to accurately measure the total volume of paste printed. Several years later, we see the same need for surface-mounted component inspection with AOI systems.

Trends From the Show: Solder and Software

03/18/2020 | Nolan Johnson, I-Connect007
In my role as a media representative, my perspective on IPC APEX EXPO may be a bit different from that of many attendees. Since the I-Connect007 team had the opportunity to talk to many attendees and exhibitors and listen to their stories over the course of the week, our view can be particularly wide. When I reflected on all the conversations, pieces from all throughout the week coalesced and provided a different understanding of and takeaway from the show.
