Creating a printed circuit board by laser iron (LUT)
LUT method is to transfer the toner to the PCB by heating it . For the manufacture of printed circuit boards in this way , we need a laser printer (I use Canon LBP6000),
photographic Ink I I use this : 
or - the pages of glossy magazines. First we need to draw a diagram . Best suitable for beginners Sprint Layout. Next we print the scheme on paper using a laser printer (the printer settings may want to disable saving toner and resolution set to maximum, the density of the toner deposition was highest ).
After that we need to cut the size of PCB board to clean it thoroughly with a fine sandpaper grit of about 1600 degrees and degrease with alcohol.
Next we have to impose on the PCB paper , toner course to foil and secure with duct tape or like convenient manner.
All it warms iron about 1 - 2 minutes (depending on the quality of materials ) . Iron is desirable to take more powerfully . I use like this .
Next give the board cool to room temperature and throw in a bath of warm water to soak the paper
After disintegration , the paper can roll your fingers or gently scrubbed with a toothbrush. Here we have all done carefully to avoid damaging the toner, but if a damaged track - not terrible, it can finish a waterproof marker ( for subscription CD / DVD). Here's what happened as a result of
Now we need to prepare a solution for marijuana charges. For the preparation of pickling solutions need to use a plastic or glass container . The solution can be made from a plurality of ingredients , the most common - is ferric chloride and water but also hydrogen peroxide may be used
and citric acid,
( will render a little longer , but is much cheaper and safer) . Preparing it so : In 100 ml of pharmacy 3% hydrogen peroxide ( gidroperit ) was dissolved 45 g of citric acid and 5 g of salt .
The more hydrogen peroxide solution is , the faster the etching process , but not too much as necessary the solution is stored , i.e. not reused , and thus will simply gidroperit overdrawn . Excess peroxide is readily identified by strong outgassing during grass .
You can also use lemon instead of acetic acid , but the etching process is accompanied by an unpleasant odor , and the etching rate decrease slightly .
PCB possibly better to place the foil to the bottom to fallen off pieces of copper fell down ( for this I taped foam glued to the PCB , or anything placed under the edge of the PCB ) .
When the process is desirable grass periodically shake PCB . All process grass finished!
Now we need to remove the toner from the tracks . For this I use a solvent - alcohol or acetone . Take a tissue soaked with acetone and wipe the surface of the board or sandpaper scraping
All our board is ready now ! You are ready for installation details.
