The thermal transfer pcb papers is an efficient and easy tool to manually print your circuit. It enables you to get very fime and tiny details you can not get with other manual methods. The paper size is A4 (21x 29.7cm).
These are the qiuck and rough steps to make your on printed circuit:
- Print your circuit on the pcb thermal transfer paper usig printer.
- Put the thermal transfer paper on the pcb and use iron to get the printed circuit drawn on the pcb.
- Put the pcb in ferrite choride or acid for suitable time.
- Clean the pcb with water, now you have your circuit ready for welding components.
