MEP EP#257: Viciously Different Creams

Parker

• 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.
• Kicad - Panelization
  • Moving between layers has hotkeys - yay
