Silk-screen printing has the cost lowly, the operation simple, the production efficiency high, the printing material type are many and so on the characteristic, widely applies to the printed circuit and the latter mold integrated circuit manufacture, concrete table now electric circuit board anti- layer, electric circuit board graph shift, in electric circuit board surface mark application. Along with the digitized time arrival, the printed circuit board demand quantity increases day by day, the silk-screen printings is even more obvious in PCB production function。 Keywords: silk-screen printing Operation Application Study 目录 1 引言… … … …… … … …
