RESIN SEALED BODY

摘要

PURPOSE:To prevent a sealing resin from diffusing without increase in the cost by coating an ink mark in the prescribed thickness on the sealing region peripheral edge of a substrate. CONSTITUTION:An ink mark 5 is formed on the periphery of the sealing region of a sealing region 4 formed to surround an IC module 2. The mark 5 is formed by coating paint for preventing a precoating resin 4 from diffusing in the prescribed thickness in the printing step in case of forming printed wirings on an IC substrate. Thus, it can prevent the sealing resin of the resin 4 from increasing more than required to solder the parts such as resistors near the region. An exclusive step for forming the mark 5 is not necessary.
