Designing a new product but worried about all these component shortages and increasing lead times? This week, Parker discusses designing around this.

Parker

  • What can you do to help alleviate component shortages and lead times in your design
    • Last week we talked about automotive component shortages
    • Passive components
      • Most passives it is easy to find substitutes
      • Check your specifications
        • Components that have extraordinary specs for there package size
    • Active components
      • Diversify what you can
        • Discretes
        • Diodes 
        • Mosfets
      • Integrated Components
        • Different packages or packaging
    • Connectors
      • Different plating options possible?
      • Other manufactures making similar or compatible parts

Stephen

  • Searching for components kind of sucks sometimes. Another Quick idea for making this easier
    • Anything that is a complement
      • Connectors
      • Transistors
        • Guessed BCP54 – BCP52
  • PCB Crosstalk
    • Video by Robert Feranec with Eric Bogatin
    • What causes PCB crosstalk?
      • Capacitive coupling
      • Inductive coupling
    • Effects of pcb crosstalk
    • How do we mitigate pcb crosstalk?
    • One other form of “crosstalk” that really isn’t crosstalk
      • Poor filtering and PSRR
      • “Feedforward” current
      • Not really something that shows up often…

About the Hosts

Parker dillmann
  Parker Dillmann

Parker is an Electrical Engineer with backgrounds in Embedded System Design and Digital Signal Processing. He got his start in 2005 by hacking Nintendo consoles into portable gaming units. The following year he designed and produced an Atari 2600 video mod to allow the Atari to display a crisp, RF fuzz free picture on newer TVs. Over a thousand Atari video mods where produced by Parker from 2006 to 2011 and the mod is still made by other enthusiasts in the Atari community.

In 2006, Parker enrolled at The University of Texas at Austin as a Petroleum Engineer. After realizing electronics was his passion he switched majors in 2007 to Electrical and Computer Engineering. Following his previous background in making the Atari 2600 video mod, Parker decided to take more board layout classes and circuit design classes. Other areas of study include robotics, microcontroller theory and design, FPGA development with VHDL and Verilog, and image and signal processing with DSPs. In 2010, Parker won a Ti sponsored Launchpad programming and design contest that was held by the IEEE CS chapter at the University. Parker graduated with a BS in Electrical and Computer Engineering in the Spring of 2012.

In the Summer of 2012, Parker was hired on as an Electrical Engineer at Dynamic Perception to design and prototype new electronic products. Here, Parker learned about full product development cycles and honed his board layout skills. Seeing the difficulties in managing operations and FCC/CE compliance testing, Parker thought there had to be a better way for small electronic companies to get their product out in customer's hands.

Parker also runs the blog, longhornengineer.com, where he posts his personal projects, technical guides, and appnotes about board layout design and components.
