Abstract

A filter is disclosed. The filter in accordance with an embodiment of the present invention is installed in a conduit through which resin mixed with filler passes, and includes a plate having an area corresponding to a horizontal section of the conduit and having a plurality of openings formed therein for filtering the filler. Each of the plurality of openings includes a first opening area and the second opening area that intersect with each other and are each elongated in one direction and have a predetermined width for filtering the filler.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0123807 filed on Nov. 2, 2012 with the Korean Intellectual Property Office, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a filter. Background technique [0004] Today's high performance, smaller electronic devices increasingly require thinner boards with improved signal transmission speeds. Printed circuit boards used to meet such market demands need to have little warpage during the fabrication or packaging process. [0005] The main cause of warpage in printed circuit boards is the incongruity of the coefficients of thermal expansion between materials in the crystalline structure. In order to reduce the inconsistency of CTE, constituent materials other than copper need to have small CTEs, for which many studies are actively being conducted. [0006] In practice...
