Need for tools

Still on the topic of the USB charger... I ordered some samples from TI for some various components:

  • TPS2561A dual-channel current-limited switch
  • TPS2513A dual-channel dedicated USB charging port controller
  • TPD2E001 ESB protector

TI was gracious enough to ship some samples to me. (I also ordered a demo board with all these components mounted so I can conduct some experimentation)I'm glad I ordered the demo board.Upon looking at the chip, I'm realizing I need some new tools. I knew I needed a new soldering iron -- now I know I need a microscope as well.!!The dimension's of this chip are 3.1mm square. The "pins" are on 0.5mm centers with each pin nominally 0.25mm wide (0.18mm - 0.30mm actual)Yeah. I think I need some visual enhancement.
