MEP EP#224: The Normal Chaos
Stephen
- DC Heating and Thermal Testing
- A low voltage moderate current linear power supply
- 12.6V dc @ 0.55A 6.93W
- LM2940T-12.0 LDO
- TIP42 bootstrap transistor to share the load
- 12V @ 2A transformer supplies ~16.2vdc with 200mV ripple
- ~2W of heat to be handled
- Shooting for about 250mW in the regulator and the transistor then the rest will get dumped in some resistors
- PCB heatsinking
- Diptrace 4.0 is finally here!
- Snapping and aligning items
- Circles and arcs actually have a center now…
- Paste and Mask layers are finally visible
- Pad angles other than 0 and 90 are now available in the pattern editor
- One button for removing silkscreen from pads
- Progressive searching for components instead of the seizure it used to be
- Export options now can export all the manufacturing files as a single zip
- Teardrops!
