1.purifier circuit board design printed circuit board

　　Print the drawn purifier circuit board with transfer paper, pay attention to the slippery side facing you, generally print two circuit boards, that is, print two circuit boards on one sheet of paper.

　　2. Cutting copper clad laminate for purifier circuit board

　　A diagram of the whole process of making a purifier circuit board with a photosensitive plate. Copper clad laminate, that is, a circuit board covered with copper film on both sides, cut the copper clad laminate into the size of the circuit board, not too large to save materials.

　　3. Pretreatment of copper clad laminate

　　Use fine sandpaper to polish off the oxide layer on the surface of the copper clad laminate to ensure that the toner on the thermal transfer paper can be firmly printed on the copper clad laminate when transferring the purifier circuit board. No visible stains.

　　4. Transfer purifier circuit board

　　Cut the printed circuit board into a suitable size, stick the side with the printed circuit board on the copper clad laminate, and put the copper clad laminate into the thermal transfer machine after alignment. Make sure that the transfer paper is not misplaced when putting it in.

　　5. Corrosion circuit board

　　First check whether the transfer of the purifier circuit board is complete. If there are a few places that are not transferred well, you can use a black oil-based pen to repair them.

　　6. Drilling holes on the purifier circuit board

　　The circuit board is to insert electronic components, so it is necessary to drill holes on the circuit board.

　　7. Pretreatment of purifier circuit board

　　After drilling, use fine sandpaper to polish off the toner covering the circuit board, and clean the circuit board with clean water.
