    • A method of making printed circuits, where on both sides sacrificial foils are laminated onto a synthetic resin prepreg. Through-holes are drilled. The copper foil is subsequently etched off. A negative photoresist foil is laminated on the prepreg surface roughened by etched-off copper dendrites. The foil is exposed and developed in accordance with the respective conductive pattern. Subsequently, copper is sputtered onto the surface of the photoresist, the surface and the bottom of the photoresist channels defining the conductors, and onto the surface of the drilled holes by means of magnetron-enhanced cathode sputtering. The copper sputtered onto the surface of the photoresist is removed by means of a scrubbing roller. Then, copper is deposited in accordance with the additive process on the copper sputtered in the photoresist channels and the drilled holes. After the stripping of the photoresist, the printed circuit is completed.
    • 一种制造印刷电路的方法,其中在两侧将牺牲箔层压在合成树脂预浸料上。 穿孔穿孔。 随后蚀刻铜箔。 通过蚀刻的铜枝晶,在预浸渍体表面上层压负性光致抗蚀剂层。 根据相应的导电图案将箔曝光和显影。 随后,将铜溅射到光致抗蚀剂的表面上,光刻胶通道的表面和底部限定导体,并通过磁控管增强的阴极溅射溅射到钻孔的表面上。 溅射到光致抗蚀剂表面上的铜通过洗涤辊除去。 然后,根据在光致抗蚀剂通道和钻孔中溅射的铜上的添加方法沉积铜。 剥离光刻胶后,完成印刷电路。
