摘要： A method for masking through-holes during the manufacture of a printed circuit board comprises providing a substrate having a plurality of through-holes. A removable masking seal comprised of a soluble material, a light-setting material or a thermo-setting material is formed on the surface of the substrate to cover at least one of the through-holes. At least one of the through-holes that is not covered with the masking seal is filled with a filler material by a conventional silk screen process. The masking seal is then removed, either by dissolving the masking seal in the case of the soluble material, or in the case of the light-setting or thermo-setting material, the masking seal is set by applying light or heat to reduce adhesion between the masking seal and the substrate, and then the set masking seal is peeled off to expose the through-hole.

摘要： An automatic silk stretching apparatus for stretching silk on a silk screen printing frame is provided. At first silk is stretched to four sides by first stage stretching by cramp table and second stage stretching by stretchers on the cramp table. From lower side of the cramped silk, a printing frame on an elevator table is lifted and urges the silk. Adhesive is applied on the frame, and is forcibly dried. Then, the excess silk surrounding the frame is cut. The silk stretched frame is discharged, an empty frame is fed and further new silk is cramped.
