CSP (Chip Scale Package) package, chip-scale packaging means. CSP packages the latest generation of memory chip packaging technology, its technical performance has a new upgrade. CSP CSP package installed seal allows the chip area and packaging area ratio exceeds 1:1.14, very close to 1:1 has been the ideal situation, the absolute size is also only 32 square millimeters, about the ordinary BGA 1 / 3, only very TSOP memory chips in the area of ??1 / 6. Compared with the BGA package, under the CSP and the same space can be three times more storage capacity.
