Memory Card

PTI offers packaging and testing services for the memory card-micro SD Card by supporting multi-chip, wire bonding, surface mounted passive components, and then molding them into one identical module. Stacking dies to increase memory density but without re-designing the substrate can ensure that our customers gain cost-effective solutions with increased time-to-market results.

PTI's micro SD Card technology is an ideal solution for mobile devices, such as cellular phones, PDAs, MP3s, mobile games, and others portable products which need data storage back- up.

widely adopted for applications such as digital cameras, MP3 players, cellular phones and PDAs.
