Better to Light a Candle: Chapter Two—Introduction to PCB Fabrication


Reading time ( words)

Editor’s Note: This column is part of a series on a new university course in PCB manufacturing at Michigan Technological University. Marc will chronicle the progress of this class, interview the guest lecturers, introduce the students, etc. The interview with students was also edited for clarity.

In my first column, I reported on a grassroots effort being started to prepare the next generation of printed circuit board (PCB) “experts.” A fortunate alignment of academia, the industry, resources, and concerned, well-seasoned board geeks came together to pass on PCB experience to the next generation through a very practical design, build, assemble, and test opportunity at Michigan Technological University (MTU). I also shared the thoughts of a few of the many people that were key players in getting this effort started. 

As a reminder, “EE4800: Printed Circuit Board Fabrication” is a hands-on class intended to give engineering undergraduate students an introduction to the basics of printed circuit design, fabrication, and assembly, which started on January 14 of this year. A high-level overview of the course, it’s approach, and goals can be seen in the poster shared at several events at IPC APEX EXPO 2019 in San Diego, California (Figure 1).

Here’s an abridged excerpt of the course description:

“Printed circuit board fabrication techniques are presented and explored utilizing wet-chemical process techniques. Single and multilayer boards using internal layers for power and ground planes as well as plated feed-through via structures, solder masks, and silk screens will be discussed. While hands-on fabrication will be the main focus, students will be introduced to software design packages specific to circuit layout and design. Final testing and evaluation of the fabricated boards will be performed.”

A major portion of the class consists of guest lecture presentations by industry experts, many whom traveled to Houghton, Michigan, this winter to provide the most direct interactive experience for the students. A schedule of those lectures can be found in Table 1.

New High-speed 3D Surface Imaging Technology in Electronics Manufacturing Applications

10/09/2019 | Juha Saily, Focalspec Inc.
Line confocal sensors—and scanners based on them—are used in the imaging of surfaces, transparent materials, and multi-layered structures in various metrology and inspection applications on discrete parts, assemblies, webs, and other continuous products. Line confocal sensors operate at high speed and can be used to scan fast-moving surfaces in real-time as well as stationary product samples in the laboratory.

In Part 1 of this six-part series for "Fab Fridays," Mark Thompson, CID+, engineering support at Prototron, and CA Design CTO Bob Chandler discuss ways that PCB fabricators and designers can better communicate, starting with how to qualify a board shop.

The Institute of Circuit Technology Autumn Seminar

10/03/2019 | Pete Starkey, I-Connect007
Meriden has been established as a popular Midlands venue for Institute of Circuit Technology (ICT) meetings. On September 19, a multitude of Fellows, Members, and Associates gathered for the Institute’s autumn seminar, which was organised and hosted by ICT Technical Director Bill Wilkie. The agenda included five informative technical presentations, describing current research and development on significant topics relevant to the industry.
