Common IC package types: DIP, SOIC, QFP, BGA and more
DIP for prototyping and through-hole designs. SOIC/SSOP for standard SMD. TSSOP/MSOP for space-constrained designs. QFP for high pin-count ICs. BGA for highest density (see Grid Array page). Consider soldering capability: DIP and SOIC are hand-solderable; fine-pitch QFP and BGA require reflow.
