Feature:Heat transfer law making circuit boards, circuit board is drawn graphics, laser printers print in thermal transfer paper, transfer paper and then covered in Bonded Copper, after heating, the melting of the toner completely adsorbed on the deposited copper, and other cool tear off transfer paper, you can see the graphics board has to transfer to the Bonded Copper on the black anti-corrosion layers, that is, we want to map the PCB, and finally to corrosion, and that we want to obtain the PCB board. The process of making iron tools used in heating or over-presses. We serve the transfer paper for the production of circuit boards dedicated thermal transfer paper, with its production of circuit board has the following advantages:. 1 plate with high precision.2, plate cost.3, plate-making speed.4, can produce double-sided. Usage: 1 circuit board with a laser printer to print to the circuit diagram of the smooth thermal transfer paper.2 Raised with the laminator between 150-180 degrees Celsius, the heat transfer printed circuit side of the paper deposited in the Bonded Copper on the transfer; the system can also be used instead of iron plate machine, hand transfer. 3 Remove the transfer paper after printing, the Bonded into the ferric chloride solution to corrosion.4 Finally, remove the circuit board using toner. In the package??0PCS x A4 Heat Toner Transfer Paper For PCB Electronic Prototype Top quality The merchant warrants that their products comply with all applicable laws, and are offered only if they comply with Jooms policies and EU Product Safety and Compliance laws.
