Introduction

In this article, we'll explain how to make integrated circuits of single or double layer, with the help of sheets wet with high temperature silicone
Normally the toner transfer method is used with magazine sheets or glossy paper, but our practical results are not optimal, because the toner quits from paper with a lot of difficulty, and also in the last stage the cellulose adheres to the copper clad, and the cleaning is very time consuming.
If we add silicone to a sheet of paper and print a circuit with the laser printer, the toner doesn't go out completly fused, so it's very easy to transfer this toner to the copper clad of the PCB.
Also this silicone paper can be reused as many time as you want.
