CSP Low & Thin-LFBGA
 

Product Overview

 
Low & Thin BGA is an ideal solution to meet requirements of both dense layout and small outline for ICs of I/O counts of less than 288. Four-layer BT substrates are available for these packages to provide better electrical characteristics. Low & Thin BGA was developed for space reduction. This type of package is a chip size solution based on mature laminated substrate technology and material.


Application
 
Low & Thin BGAs are suitable for high-performance ICs like flash, SRAM, DSP memory, communication ICs and RFICs. Common applications of Low & Thin BGA are computer and communication products, such as PDA, notebooks and memory cards, cell phones, mobile stations and wireless systems.
