SlimStack™ is the new family name for Molex's broad range of Micro SMT stacking board-to-board connectors. The family covers stack heights from 1.50mm (.059") to 20.0mm (.787") in pitch categories of 0.35mm, 0.40mm (.016"), 0.50mm (.020"), 0.635mm (.025") and 1.00mm (.039").

SlimStack offers system designers a wide range of flexibility to meet the tight packaging needs found in applications such as PDAs, cellular phones, camcorders, notebook PCs and other compact equipment. Along with various pitch and stack options, the series covers circuit size needs from 16 to 140.

All versions are gold-plated for high reliability over multiple mating cycles. Other features include a durable blade-on-beam contact, SMT tails that create strong solder fillets, and a friction locking feature for added mating retention.
