Paper for high-quality LUT-a


There is such a method of manufacturing boards in which the tracks are printed using a laser printer on paper, and then the toner is transferred to a PCB foil with further etching in ferric chloride or even something else. This method is called LUT: it is very cheap, does not require special skills, and at the same time, ready-made boards are of excellent quality. So, for high-quality transfer of printer toner from one surface to another, special high-temperature transfer paper is used.

For a small price, ten A4 sheets are offered, they will come to you rolled up into a tube. Flatten the paper before use.

1)A pre-divorced board must be printed on the smooth side of the thermal paper.
2)Now you need to carefully put special paper with the printed side facing bonded copper and pass through the laminator at a temperature of 150 - 180 degrees Celsius. You can also use an ordinary iron for this.
3)Remove the paper from the plastic foil PCB and place the board in a solution of ferric iron chloride to corrode the copper. To speed up the chemical reaction, heat the solution.
4)Finally, remove the circuit board, and then rinse with acetone or alcohol.
