  2. what are they?
    think “inside out breadboard”
    think “my components aren’t going anywhere”

  3. reasons why making your own
    PCBs is a good idea
    • save money (if your board is faulty you’ll know it faster than if you sent it out to
    be made and a week later you’re out cash and time)
    • learn more about electricity (component placement)
    • learn your circuit
    • once your circuit is down, it’s locked down (less sleepless nights for you finding
    the *one wire that was in the wrong place
    • circuits are attractive and neat
    • next level (form and function)
    • your friends will be impressed

  6. 5. ETCH
    PRINTING (Etching)
    supplies: (ITP Supplies these)
    funnel
    empty container to size (for agitation and used acid and )
    acid (mixed or at RadioShack)
    GLOVES!!!!
    If your transfer is OK, you can proceed to step 1 of the etching process.
    PREP: (microwave acid for 20-30 seconds before putting board in acid) *
    insert time/temperature chart here)
    step 1: acid bath agitation-- USE GLOVES!!
    step 2: use gloves.
    step 3: rinse (no touching)
    step 4: pat dry (the transfer is not quite set yet, if you are not gentle, the ink
    could rub off)
    step 5: scotch bright off black printed board to reveal copper.

  7. 4. TRANSFER
    T is for “can be tricky”
    supplies:
    scotch bright pad
    PCB paper ( can use magazine paper)
    copper PCB board
    tape
    scissors (cut your board and transfer to size)
    water
    paper towel
    Sharpie marker (for filing in traces/touch ups on transfer)
    steps:
    step 1: prepare the PCB board with ScotchBrite (in a circular motion scrub the copper until it is
    shiny)
    step 2: lay artwork print out face down onto prepared PCB board (you can use a tiny bit of tape to
    tag the layout onto the copper, but be sure to tape outside the parameter of the layout)
    step 3: run PCB board with printout (face to face) through the laminator 2-3 times
    step 5: let the water do the work (if using the PCB blue paper, it will release on itʼs own/ if using
    magazine paper, you will gently rub the artwork from the copper)
    equipment: (in wet lab)
    laminator
    printer
