Hardware:
2. An electric iron.
3. A smooth stickers at the end of Backing Paper.
4. A certain amount of ferric chloride etching solution, according to the size of the board. Added that it is better to have a digital thermometer ranged from 0~200 degrees.
Software:
Low version of PROTEL, such as PROTEL2.5, or PROTEL99SE.
One Kind Of PCB Board
Steps:
1: Using a software mentioned above to generate a number of image files, for example, you can organize SCH with low version PROTEL, then generate the corresponding PCB map using network table, or directly using PowerPCB figure PCB, for printing.
2: The PCB plans to print to heat transfer paper.
3: Put the well printed PCB heat transfer paper flatly on the CCL, prepared for transfer.
4: Heating with electric irons, pressure the black plastic powder of the transfer paper on CCL to form high-precision layer to prevent corrosion.
5: The success of iron transfer pressurized heating effect! If you engage in regular, skilled, it is very much easier.
6:Prepare ferric chloride to go on corrosion.
7: Careful! not to over-corrosion, when corrosion is of the end, get ready to weld.
8: Load the milling cutter to the bench drill, clean up the part of the pad, and the remaining part is for solder.
9: Install scheduled parts and weld.
Notes:
1.Do not make the iron too cold or overheated, the best temperature is between 140 ~ 170, within this temperature range, plastic toner transfer characteristics is the best.
2.Open the transfer paper when temperature is lower, slowly open, if you find there was not any good part of transfer, cover it again with heat transfer of pressurized heating.
3.If there is still some problems of some part (such as broken), please use oily carbon pen, nail polish, or paint to remedy, but this situation is not much.
