Abstract: A heat sink apparatus for use with electronic components comprises a base frame, a clipping system and a plurality of supporting members. The base frame and the clipping system and the supporting members are of unitary construction. The base frame is configured to have “i” repeatable channels with fins extended from or attached to its outside surfaces. The clipping system comprises a matrix [i, j] set of i×j spring clips. Each spring clip is configured to have partially constrained with the base frame, and to flex about an axis resiliently to effect an engaged relation to substantially fixedly maintain the electronic component in abutting relation with the inside walls of the channel. The supporting members are configured to have fixed connection with the base frame and be solderable. The heat sink apparatus's capacity of holding electronic components is scalable to accommodate upgrades and design changes of electronic products.
