5PCS BLUE PRESS N PEEL film for home production of CS printed circuits

Special sheets of paper that allow you to create printed circuits without using a bromograph. No more photoengraving, thanks to a film on which you just need to photocopy or print the master. Pack of 5 pieces.

The process of making a printed circuit with the "PnP" method (PRESS n PEEL) allows to eliminate the numerous steps required by the traditional photoengraving method. A transparent film coated with a blue substance is used, which allows the tracks of the printed circuit previously imprinted on the sensitive side of the film to be transferred to the copper-plated surface of a plate by means of a photocopier or a laser printer. With no further steps, you can go straight to engraving. In practice, it is sufficient to make a photocopy of the master on the sensitive surface of this film, or to print the cs trace on it with a laser printer; it is then necessary to place the printed part on the copper of the base and pass an iron over the shiny surface for a few minutes. Supplied complete with instructions for use. Single sheet format: 21.6 x 28.4 cm.

PHASES OF CREATION OF A PRINTED CIRCUIT

1 Draw the project and the relative Master using any CAD program.

2 Print the mirror image of the Master onto paper and photocopy (or print directly with a laser printer) onto the rough side of the PnP paper.

3 Cut the sheet so that you can reuse the rest of the paper for other circuits.

4 It is advisable to leave about a couple of centimeters of margin with respect to the cs

5 Thoroughly clean the copper base with alcohol.

6 Lay the PnP paper so that the toner contacts the copper

7 Pass the iron (170°-190°) over the paper in order to heat it uniformly.

8 Leave to cool and peel the PnP paper off the copper base.

9 Immerse the board in the acid to corrode the excess copper.

10 The result after corrosion is the board with the desired copper tracks.

11 Clean the plate using nitro thinner.

12 Check for any shorts due to uneven corrosion.

13 Once the printout has been completed, it is time to assemble all the components and thus assemble the complete board.
