Sealing Resin Leakage Prevention & Dam Technologies

Features

  • Completely eliminates the leaking of resins used to seal chips to the through hole. There are two methods used.
    • Permanent filling (Satosen has the equipment in-house to carry this out)
    • A copper layer tent for the solder through hole that is made to withstand transfer molds

  • Forms a dam for the resin seal after component installation. There are three methods by which these dams are formed.
    • Thick film silk printing dam
    • Film shaping thick film solder dam
    • Laminated dam

  • Dam formation technology aimed at flip chip implementation

With C4, NCP, NCF and similarly induced flip chip installation, Satosen seeks to prevent shorts as well as chip stability in narrow-pitch area through the use of a film-shaped solder resist.
