Thermal transfer paper enables PCB manufacturing.
After designing the printed circuit in one of many programs, you must print the project on paper on a slippery page (in the reflected image) with a laser printer. The pattern (printed side) is transferred to the laminated plate from the copper side using the hot iron (the toner adheres to the copper under the influence of temperature).
It remains only to peel off the paper under water and start to engrave the laminate. It can be attacked with the Printed Circuit Recorder solution A4 Thermal Transfer Film for DIY PCB circuits features:

- material: A4 thermal transfer foil - quantity: 1 sheet
