- The ole ordered a 0603 and it was metric instead resulting in an 0201 imperial chip component.
- 0.6mm x 0.3mm = 0.024” x 0.012”
- 0201 imperial chip size only size that does not match the actual size
- Imperial 0201 is 24mil x 12mil… not 20mil x 10mil like the name implies
- Imperial 0603 is 60mil x 30mil
- 0603 metric is the only standard metric size that has the same size code as an imperial one!
- Does anyone actually use the metric sizing for chip components?

- Hardware v software – Features and their impact
- Hardware
- needs a lot of motivation to make a feature. It is slow and deliberate. Removing features is a big deal
- features by default cannot break the device unless extreme cases are encountered
- Software is “easier” to flip the switch on features.
- Have to consider all the ways this will break things.
- Hardware
- Kicad – Panelization
- Moving between layers has hotkeys – yay
- Middle mouse now by default pans and wheel is zoom
- Snap to points is huge
- Creating arrays actually creates arrays
- There are pluses and minuses to this.
- Ref Des is maintained!
- Changes to one board are not copied!
- Holes are not a function…..They are a footprint and therefore need to be created.
- Most tutorials suggest that Mouse bites be made a part….
- Buying new machines
- Sometimes being an engineer is annoying but you still have to do it
- Learn from my experience
- Air Hose
- Solvent
- Power Cable
- If you are a machine provider also consider these things
About the Hosts
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.
Stephen Kraig
Stephen Kraig is a component engineer working in the aerospace industry. He has applied his electrical engineering knowledge in a variety of contexts previously, including oil and gas, contract manufacturing, audio electronic repair, and synthesizer design. A graduate of Texas A&M, Stephen has lived his adult life in the Houston, TX, and Denver, CO, areas.
Stephen has never said no to a project. From building guitar amps (starting when he was 17) to designing and building his own CNC table to fine-tuning the mineral composition of the water he uses to brew beer, he thrives on testing, experimentation, and problem-solving. Tune into the podcast to learn more about the wacky stuff Stephen gets up to.
