Popular ICs: microcontrollers, sensors and interfaces
Microcontrollers, IMUs, USB bridges and radio chips that show up on board after board. Most are QFN or small gull-wing packages; several have non-square exposed pads or short leads that catch people out.
The numbers you program
- Body and pitch
- Exposed pad size (it is not always square)
- Lead length L
- MSL level
Mistakes to watch
- Assuming a square center pad
- Wrong revision of the datasheet drawing
- Bag left open over a long weekend
Each of these has a check in PnP Toolkit. See the test results on the proof page.
