Ben Nibali, founder and President of Aptus Design Works, with Connor Richardson, the Electrical Designer, are our guests in this episode. We will discuss how you can plan the cost and lead times to successfully launch your product in the market.

Ben and Connor share some excellent advice for designers and companies to streamline their product development process from prototyping to manufacturing.

 

Show Highlights:

• Aptus is a design and engineering company, and they’ve been around for about 15 years
  • They handle initial concept development, mechanical development, controls, and mechanical prototyping and help their clients through the launching and manufacturing of their products
• Expecting and avoiding pitfalls comes with experience; in addition, working with trusted vendors and suppliers is huge when honoring set schedules or timeline
• The natural state of every project is over budget and behind schedule. Ben Nibali stresses the importance of effort and discipline to have complete control of the process  and deliver on time
• Some unrealistic expectations by Aptus’s clients typically involve defying the law of physics
  • Other challenges include expectations from not knowing the process and cost expectations based on the higher volume of current products that really can’t be met in a US market-based launch scenario
  • Clients need to realize that there is a proper “cost of engineering”
• There are also misconceptions about 3D printing–in reality, it takes days to print 3D objects
  • You can’t have fast, cheap, and high quality at the same time
• Software guys may often misunderstand that modifications on hardware  are not as simple to execute as they will be on software
  • The “minimum viable product” is a great idea and works exceptionally well in software because you can add, modify, change, and grow something slowly after you deploy. In hardware, it is an entirely different cost structure to make changes once you start making anything physical. 
• “Proof of concept” is often neglected when companies want to launch their products immediately
• Connor Richardson shares the most complex and fun project they did at Aptus
  • Another exciting prototype they created is the cow-milking robot
• Ben gives designers and companies a piece of advice on how to plan cost and lead times when launching their products
  • The most important factor is market research, understanding what this thing that we're going to sell is? How are we going to sell it? Who's going to buy it? What features matter? 
  • The better the client understands the world they're going to try to sell into and how they're going to sell it, the more valuable our work will be and the higher likelihood that they'll make a profit
• Creating high-quality products could mean years of planning

We are very delighted to have Dr. Min Zhang in this episode. Min is an independent EMC consultant based in the UK. Today, we'll be talking about EMC, both on board and off the board. It will be a very interesting discussion because we will look a little bit deeper at the system level of the board.

Show Highlights:

• Zach met Min at EMCLive 2021
• Let’s hear more about Min’s background and his early exposure to EMI issues
  • Earlier in his career, he worked with big companies as a motor drive engineer and power electronics design engineer for 10 years
  • He started his engineering consulting business, Mach One Design EMC Consultants 2 years ago
  • His first experience dealing with EMI issues was at the university while doing research for his PhD
• The lack of education in the university in regards to EMI issues is one of the reasons that sparked Min’s interest in EMI
  • The university he went to specializes in motor and power converter design, but did not offer any solutions in fixing the EMI issues
  • Min recalls being fascinated by his first time seeing an EMI diagnosis kit composed of the spectrum analyzer, lots of ferrites, and cable shooting copper tape in a suitcase
  • It was his first time seeing a step-by-step diagnosis and troubleshooting EMI issues - checking the grounding, checking the bonding, and applying ferrites at the right place, performed by his friend’s father who was then a principal engineer in the European Space Agency
• Min’s recommendation to design engineers solving EMI issues is to understand the fundamentals – “only when you understand the fundamentals, understand the basics, and the first principle, then you can really design a system” - Min Zhang
• What happens when EMI problems exist off the board and they interfere with the system or create so much noise that the system is never going to pass EMC?
  • Min answers by recommending Rick Hartley's famous YouTube video about grounding
  • He continues with his answer with an example involving a three-phase brushless DC motor drive
• How to deal with cables connected to another system that is outside of the shielding?
  • Shielding is a good solution, but understanding fundamentals are necessary to avoid increased cost, weight, and also the bending ratio would be affected
• Min shares a recent video he did with Robert Feranec which discusses the topic of EMI troubleshooting on immunity
• 70% of the EMI issues are somehow related to resonance
  • For high-speed design, PCB designers really need to understand how the wave propagates
• Ferrite is not a 100% inductive component
• Min recommends the book by Douglas Smith – High Frequency Measurements and Noise in Electronic Circuits which focuses on the test and measurements in terms of high-speed design
• Other experts to learn from in terms of EMI troubleshooting and high speed designs are Eric Bogatin, Steve Sandler and Heidi Barnes
