Environment-friendly novel circuit board manufacturing method

Abstract

The invention discloses an environment-friendly novel circuit board manufacturing method, which comprises the following steps: a copper-clad board is cut to the size of a circuit board, and the size is not too large so as to save materials; the copper-clad board is preprocessed, the oxide layer on the surface of the copper-clad board is ground off with fine abrasive paper so as to ensure that carbon powder on heat transfer paper can be firmly printed on the copper-clad board when the circuit board is transferred; the circuit board is transferred, the printed circuit board is cut into a propersize, and the surface printed with the circuit board is attached to the copper-clad board; the circuit board is corroded, the circuit board is put into corrosive liquid for corrosion, and the circuitboard after the copper film is completely corroded is taken out; the circuit board is drilled, different drill needles are selected according to the thickness of the pins of electronic components to drill the circuit board; and the circuit board is pretreated, powdered ink covering the circuit board is ground off through fine abrasive paper, the circuit board is cleaned through clear water, afterthe water is dried, rosin water is smeared on the face, provided with the circuit, of the circuit board, and rosin solidification is accelerated through a hot-air blower.

Problems solved by technology

[0003] In the production process of the existing circuit board, a large amount of dust is easily generated due to grinding and drilling, which affects the air environment in the workshop, and when pretreating the circuit board, it is necessary to use an acid etching solution. Improper post-treatment discharge may cause great damage to the environment
