INTERPOSER, ELECTRONIC COMPONENT HAVING THE SAME AND BOARD HAVING THE ELECTRONIC COMPONENT HAVING THE SAME MOUNTED THEREON

摘要

The present invention relates to an interposer for improving mounting stabilization and attaching strength, an electronic component having the same and a mounting board having the electronic component having the same. The interposer includes an insulating substrate, a connection electrode arranged on the insulating substrate, and a concave part which is arranged to have an area on a first main surface including the insulating substrate and the connection electrode to be smaller than an area of L x W, if the L is a length including the insulating substrate and the connection electrode and the W is a width.
