Thermal-transfer printing is a digital printing method in which ink is applied to paper by printing the circuit using a laser printer then we iron the paper with ink on it on the copper PCB so the ink will transfer to the copper.
Method of use:
1 . Using a laser printer print circuit boardwiring diagram to
smooth of thethermaltransfer paper;
2.by making machine to 150 - 180 degrees celsius,the side
of thermal transfer
paper printed circuit deposited in copper clad plate, transfer;
can also be used electric iron instead ofthe making machine,
3 .after printed remove the transfer paper,put the copper
clad plate into the ferric chloride solution for corrosion;
4.The final cleaning with gasoline toner on the circuit board.
