Entry sheet for drilling hole in printed circuit boards, lubricant resin composition and method for preparing the same |
| abstract |
The present invention relates to an entry sheet for printed circuit board hole boring, comprising: a metal thin film substrate; and a water-soluble lubricating resin layer formed on the substrate, wherein the water-soluble lubricating resin layer comprises 100 parts by weight of a water-soluble polyester resin, from 0.5 to 3 parts by weight of a vinyl chloride - vinyl acetate copolymer and from 0.5 to 3 parts by weight of a hydrogenated hydrocarbon resin. In entry sheets produced in this way, the uniformity and accuracy of the bored holes is outstanding, the force of binding onto the metal thin film is exceptional, and there is no peeling or crack generation on the surface even at low temperature. |
