Soldering-PCB

a 4-bit adder used as a soldering practice pcb

Changes to be done for v2

• Update manual

Changes already made in v2 (or decided not to be made)

• Ensure no vias to different signals close to soldering points (i.e. the one by the 9V lines)
• Make 9V holes bigger
• Consider making resistor pads a tad larger
• Consider making 3V linear regulator pads a tad bigger (decided not to)
• Make the resistors values larger and J1 labels.
• Consider adding IEEE or Purdue logo on bottom left silkscreen
• Make PCB text header larger
• Consider making board smaller (see if it will actually save cost) (didn't do this)
