Firing Your Hiring Habits by John Mitchell, President and CEO of IPC

We have a seasoned favorite guest in the podcast today. John Mitchell the President and CEO of IPC talks about his new book Firing Your Hiring Habits.

This is a very insightful conversation! We tackled acquisition, retaining and upskilling talents in your team. PCB designers, aspiring entrepreneurs and leaders in any company will surely benefit from this discussion. Make sure to watch through the end and check the additional resources below.

Watch this episode here.

Show Highlights:

• Introduction to John Mitchell and his new book, Fire Your Hiring Habits
• John Mitchell shares his inspiration about writing the book and revealed who he wrote it for
• The two fundamental problems in building a team are one, acquiring the right talents, and second retaining them
• The key to retention is helping employees aspire for a career and providing them with a pathway to reach a higher goal
• “Upskilling” is also a significant factor to retaining employees especially now that we have AI’s that manage automated processes
• How is the rise of remote jobs affecting the job industry?
• A lot of people are going “hybrid” appropriate for specific positions, and found it to be very effective. Working from home 75% of the time and face to face for the rest have increased productivity and employee retention
• Human connection like in a team building can strengthen the team and can result to much better working relationships
• Does the challenges in employee turnover related to age? John has a very eye opening answer to this
• The longest chapter in John’s book talks about “company’s culture”. He explains in detail what makes a company’s culture and how sticking to principles can have a great impact to a company
• “There are always going to be limitations, but within the right limitations, there are freedoms you can afford by eliminating some things that it's just a matter of constantly asking yourself the question, "Why are we doing it this way? Why did this come about and does it still apply today?" If it does, great, we're going to keep doing it. That's an aspect we need to keep.” - John Mitchell
• Leadership loves people that brings answers
  John encourages everyone to learn from every experience, good and bad
• Talents leave, but they’ll come back to a company that matches their culture
• To sum it all up, John stresses the importance of knowing exactly the talents you need, and when you find them create an environment that works for them. Lastly, invest on them through trainings and give them room and path to grow
• “Fire your Hiring Habits” is available at Barnes & Noble. All proceeds goes to IPC Education Foundation

Show Highlights:

• Steve Sandler is in the running for Engineering of the Year along with Ken Wyatt
• Steve is doing a two-and-a-half-hour tutorial on PSMR, PSOR, and PSMR testing at the DesignCon. Molex and Tektronix are both participating in the live demonstration
  • He s also doing a presentation with Heidi Barnes, Bandanin, and Ben Denon
• A lot of conferences are going virtual. The reach is undeniably great, however, what are the pros and the cons? What is valuable to who?
• Steve talks about the conception of Picotest in the US
• Picotest made the very first water-cooled probe which he will be showing at the DesignCon
• Innovative solutions can take decades from conception to fruition, Steve shares his PdD thesis from 2011 that got him ahead of the curve
• Steve deeps dive into the water-cooled probe, how it works, and the problems it eliminates
• 21:34 Power supply stability is critical in space, 
• 23:28 What does it mean to quantify the flatness of the PDN? Steve co-authored a paper with Scott Witcher which will be presented at the DesignCon
• 26:25 Steve Sandler wrote a paper in 2015: Target Impedance Limitations and Rogue Wave Assessments on PDN Performance
• 31:29 FACTS! Computers in Space Station are being reset every 40 minutes
• 33:13 Steve stresses the importance of simulation and gives engineers a tip: “Start out with proven models and you'll get there. Get enough confidence.“
• 34:39 Steve explains why it is necessary to find the “Q” to measure PDN Flatness
• 43:19 Innovation could have happened earlier, Steve talks about the typical economic problems that could be hindering technological advancements
• 47:51 Steve gives us a brief deep dive into the “state space model” and what it’s attempting to quantify

Accessible Education for PCB Designers

One of PCEA’s (Printed Circuit Engineering Association) goals is to provide accessible education, affordable to everyone in the electronics industry.

In this episode, we are fortunate to have two passionate educators in the industry, Mike Buetow and Mike Creeden. We will talk about the PCEA’s efforts to use all possible platforms to promote educational programs for design engineers.

PCEA, it's an international network of engineers, designers, fabricators, assemblers…anyone who is involved in printed circuit development. And we promote Printed Circuit Engineering as a profession. We're looking at trying to take information, new design concepts, get them down into the manufacturing side, and then also to communicate those manufacturing constraints and make sure that they are communicated back to the design side. -Mike Buetow

Show Highlights:

• Introduction to PCEA and updates on its acquisition of key assets of UP Media Group
• Mike Buetow talks about the PCB East conference reboot
• Who can benefit from PCEA’s educational initiatives?
• Mike Creeden emphasizes the importance of in-person learning. “Online is good, but it lacks some retention…but in-person learning, you retain more,” he explains.
• To collaborate, educate and inspire is what’s behind PCEA educational efforts
• PCEA is a volunteer-driven organization
• Mike Creeden will be at the https://www.ipcapexexpo.org/in San Diego
• Mike Creeden debunks misconceptions about PCB manufacturing facilities, the skills involved, the compensation, and more
• There are some issues in design education around packaging, the Insulectro booth at IPC Apex 2023 will offer valuable knowledge about packaging
• PCEA membership is free, you can register here
  • Mentorship programs are something to look forward to
  • Currently, PCEA has chapters in Europe, Mexico, Canada, Australia, and across the United States
