Show Highlights:

• Introduction to Dr. Eyal Weiss, CTO and founder of Cybord an AI tool for detecting counterfeit hardware and components
• Dr. Eyal Weiss's company is using AI-based component inspection services to detect counterfeits and ensure component quality.
• The system utilizes images of individual components taken during the placement process, leveraging big data and deep learning technology.
• The software integrates seamlessly with existing pick-and-place machines' internal vision systems, making it a plug-and-play solution.
• AI plays a crucial role in understanding and processing the vast diversity of component types, enabling accurate identification and fingerprinting of individual components.
• Most component failures are due to component-level issues, not board-level failures, making it crucial to focus on component quality.
• The traditional industry approach treats components as bulks, similar to handling grains, without addressing them individually.
• AI and big data technology now enable the ability to address components as individuals, allowing for better traceability and targeted recalls.
• Dr. Eyal Weiss's company uses AI and image analysis to examine individual components, providing detailed information about quality, authenticity, and potential defects.
• By analyzing individual components using AI-based inspection, manufacturers can conduct more targeted and efficient recalls based on specific fingerprint information.
• AI-driven analysis can also identify mismatches in traceability information, preventing wrong recalls and improving recall precision by targeting smaller groups of components.
• The AI system uses image recognition and natural language processing to interpret component markings and extract relevant data for traceability.
• The individual component level traceability is recommended in the latest IPC standard (IPC-1782B) and can provide the highest level of traceability with minimal additional cost.
• The AI system's feedback allows OEMs and CMs to improve their processes and make informed decisions on recalls, ensuring a win-win situation for both parties.
• Dr. Weiss wishes everyone success and a lifetime of no recalls ;)

• Social sustainability poses greater challenges as there is no clear process and requires multidimensional teams to address issues like worker health, labor practices, and corporate governance
• Vendor checklists and assessments are used to vet suppliers, but there is a need for increased transparency and honesty in supply chains
• Companies rely on policies and regulations to ensure compliance throughout the supply chain and are pushing for accountability and reliability from their suppliers
• Kelly Scanlon emphasizes the need for a strong community and collaboration to address environmental, social, and governance sustainability in the electronics industry.
• Designers play a crucial role in driving sustainable practices by incorporating conscientious and intentional lifecycle management in their design decisions, and by advocating to manufacturers to prioritize sustainability

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
