Packages To Avoid
• Many parts come in multiple packages, make sure you are ordering
the correct one
• Avoid BGA, CSP, WSP, DFN, QFN, TQFP, TSSOP, SSOP Packages
• Avoid packages with bottom side thermal pads
• If you absolutely need a part that comes in one of these packages,
consult your TA or the ECE Shop about soldering the part
• Breakout boards are available for some hard to work with parts
– Check sparkfun.com for breakout boards
On Your Own
On Your Own
• Most manufacturers will provide free samples of parts and
encourage students to use their free sample service for class
projects
– Some have limits: Analog Devices 2 parts only
– Samples can usually be requested easily through the manufacturers website
• The course “textbook”
– If you exceed your budget or for some other reason can’t get what you need,
buy it on your own
