SMTAI 2019: Happy Holden’s On-the-Scene Report


Reading time ( words)

Last week concluded the 2019 SMTAI conference in Rosemont, Illinois. Overall, I think the show was successful and covered all aspects of SMT processes.

Professional development courses were held on Sunday and Monday, which were useful for anyone new to SMT and those wishing to increase their specific knowledge. Technical sessions started on Monday and ran through Thursday. Monday was also set aside for the Women’s Leadership Program, and mid-day, we received another update on the IPC’s Weak Microvia Interface Program investigating the root causes of a new reliability failure in stacked microvias. IPC will work with the European Space Agency on their HDI space qualification study.

Tuesday saw the first keynote delivered by Adam Steltzner, Ph.D., from NASA’s Jet Propulsion Laboratory (JPL) who talked about, “The Right Kind of Crazy: A True Story of Teamwork, Leadership, and High-Stakes Innovation.” Adam gave a very interesting and entertaining presentation about how his team at JPL came up with the soft-landing method, also called “the sky crane,” for the last Mar’s Curiosity Rover—a real problem never tackled before for a 900-kg vehicle the size of an automobile. They also had no way to test it completely on the Earth—only through simulations.

The Young Professionals Program started on Tuesday, and the exhibition opened the same day; both continued through Wednesday. Further, Wednesday continued with a keynote by W. Michael Hawes, D.Sc., from Lockheed Martin Space with “To the Moon and Back: Orion’s Next Jump Into Deep Space.” Dr. Hawes provided a review of NASA’s Orion Program to go back to the moon and stay this time.

At the exhibition, there was enough representation of vendors present to showcase the latest technologies (e.g., SMT pick-and-place equipment by Panasonic, Fuji; solder paste materials by Indium and Kester, etc.). There was a relatively large number of X-ray and optical inspection equipment vendors offering more or less the same functional products. Unlike Nordson and Koh Young, most of the vendors are new in the X-ray inspection sector.

Laserssel offers a unique selective solder reflow equipment. Compared with conventional reworking with a hot air gun (for both array and peripheral packages and soldering iron (for peripheral packages) at prolonged heating, Laserssel’s equipment enables fast and effective rework of assembled devices with minimum impact to neighboring devices. Also, Kurtz Ersa showed a fixture-free board routing technique that uses strong magnetic tooling pins precisely placed on a routing table by a robotic arm. Multiple pins are digitally placed around four corners of the panel to make it square, and some pins are placed under the panel for support during routing operation.

I also noted that many vendors sported banners stating that they were compliant with IPC-Connected Factory Exchange (CFX). Smart factory automation has increased in applications. One particular new exhibitor was Seica S.p.A. of Italy, which makes AOI inspection equipment for SMT assembly and bare boards. What caught my eye was their small connection box—the ShoeBox—that will enable older equipment to connect into the new IPC-CFX network. The ShoeBoxes, one as a monitor and one as a master, utilize the Raspberry Pi computer and its 40-pin general-purpose input/output (GPIO) to provide analog-digital lighting power, timing, and message control for existing equipment via two different wireless radio and one power line channels to an Ethernet local area network (LAN) of 10/100 Mbps for Modbus or IPC-CFX protocols.

The exhibits closed on Wednesday with a gala of apps and refreshments. I hope to see many of you next year.

I recently spoke with Rob Boguski, president of Fremont, California-based Datest and an SMTA vice president and board member. Rob explained why today’s test customers are asking for more information than the traditional pass/fail, offers a preview of SMTA International, and gives an update on SMTA’s planning strategy for the next five years.

Four Silver Linings in the Stormy Clouds of Pandemic, Supply Chain, and Inflation

09/14/2022 | Dr. Ronald C. Lasky, Indium Corp.
It may be difficult to see any bright spots in the current and recent economic situation. We have all experienced the devastation of the pandemic, supply chain issues, and most recently, inflation. However, as a senior technologist for an international materials supplier (Indium Corporation) and a professor of engineering at an Ivy League research university (Dartmouth College), I offer these four silver linings for those of us in the electronics industry.

Solder Paste Printing and Optimizations for Interconnecting Back Contact Cells

07/26/2022 | Narahari S Pujari and Krithika PM, MacDermid Alpha Electronics Solutions
The interdigitated back contact (IBC) is one of the methods to achieve rear contact solar cell interconnection. The contact and interconnection via rear side theoretically achieve higher efficiency by moving all the front contact grids to the rear side of the device. This results in all interconnection structures being located behind the cells, which brings two main advantages. First, there is no frontside shading of the cell by the interconnection ribbons, thus eliminating the need for trading off series resistance, losses for shading losses when using larger interconnection ribbons. Second, a more homogeneous looking frontside of the solar module enhances the aesthetics.
