Global Sourcing Spotlight: Get Out of China? It’s Quite ComplexITW EAE Launches PCB Temp Monitoring for Prodigy Dispenser
May 20, 2019 | ITW EAEEstimated reading time: 1 minute
ITW EAE is introducing a patent pending option for the Camalot Prodigy dispenser that was developed to ensure process stability and increase yields for underfill applications. In applications where board heat is required, a constant product temperature through the dispense process is critical to ensure process stability and repeatability. Underfill materials vary in viscosity and filler types, therefore the heat requirement for the board also varies.
The new infrared temperature sensors measure in real time the top-side board temperature which allows the system to provide closed-loop control to maintain the product within the specified temperature range.
The sensors provide a closed loop, fail safe means to monitor and control the “top side” board temperature through each of the process zones (pre-heat, dispense heat and post-heat zones), which are typically used during the underfill process. The passive IR sensors can be configured in any or all three conveyor zones in single or dual lane systems.
“Closed-loop control of the heat process is critical when dispensing underfill,” said Hugh Read, ITW EAE Dispenser Group Business Manager. “Yields are impacted due to poor capillary flow when the board temperature is outside of specified tolerance range. IR sensors ensure higher quality by improving heat stability during the dispense process.”

Punching Out: What Do Buyers Expect?
11/30/2023 | Tom Kastner -- Column: Punching Out!For sellers, the whole process is relatively simple: They may say it’s not just about the money, but in truth, it is. Sellers also want a quick process, most of their money upfront, and a reasonable expectation that any deferred compensation will actually be paid. They’re usually concerned that the buyer will take good care of their employees, customers, suppliers, and other stakeholders, and that the seller’s responsibilities after closing, if any, be acceptable. But what do buyers expect? A lot.
Tim’s Takeaways: Take It From Scotty, Simple Really is Better
11/30/2023 | Tim Haag -- Column: Tim's TakeawaysI am, at heart, a die-hard “Star Trek” fan. When I was a kid, I was all about phasers, warp drive, and cool stuff like that. However, these days, I tend to put a higher value on production and storytelling. But like any fan (I’m avoiding “Trekkie” because, frankly, it’s kind of embarrassing), I have certain moments from the hundreds (if not thousands) of hours filmed for the various TV shows and movies that are among my favorites. One of those moments is in “Star Trek III, The Search for Spock,” when our heroes steal the Starship Enterprise from space dock.
Registration: From Raw Data to Intelligent Manufacturing
11/27/2023 | Andrew Kelley, XACTPCB LTDWhile previous industrial revolutions have introduced factories, mass production, and computer-controlled systems, the advent of Industry 4.0 and the concept of the Smart factory have ushered in a new era in PCB manufacturing. For the PCB industry it is a very ambitious and aspirational objective to evolve from disconnected processes to an integrated system with automated data capture, real-time data analysis, process visualization, autonomous control, and self-correcting processes.
