I have to say this board we made is more or less useless, because we make it for demo, and we forgot double check the traces after we use laminator to transfer the toner, so some traces may in error.
What all you need is:
Laminator machine can reach 200 degree
Etch solution (Available from Electrodragon)
Toner transfer paper (Available from Electrodragon)
* Sand Paper 1000 and 600
Copper Board 10*15 (Available from Electrodragon)
* Printer and A4 paper
Oil marker pen
For the toner transfer paper, you sell it in a roll, please unroll it by flatting with some heavy materials.
All photos took by cell phone, sorry for the bad quality.
Step 1: 1. Print on the White Paper
Print your board file directly on the white paper, we use nanino project, which is very suitable for making home-made arduino. See below.
Step 2: 2. Cut and Tape the Toner Transfer Paper
Once taped, put the A4 paper with taped toner transfer paper into the paper tray with right direction and side, print it again, you will get, for my printer, the marker is on the back side of the paper:
Step 3: 3. Sand Your Copper Board, Re-tape
Remove the toner transfer paper away from the A4 paper, put the front side towards to the copper board, tape them together. Now it’s no matter where you tape, you can tape directly on the transfer paper to make sure they are firmly locked together.
Step 4: 4. Toner Transfer and Double Check
Now you should double check all the lines (traces) to see if all goods, we use a oil black marker to redraw the lines, you can see the words “EDN” (not END ) for demo
Step 5: 5. Etch
Some toner off during washing.
Step 6: 6. Get Rid of the Rest Toner on the Board
One more step is I used a bigger cutter to cut the rest of the board, easily like cutting cake just a quick solution, you get use a PCB cutter.
Drilling holes we will not mention here anymore, you can also get drill bit at electrodragon.
Looks great ?! It’s very simple, how you like.
