[WL-CSP] LSI Package Size
World's smallest ultra-compact package
Wafer-level CSP is the world's smallest ultra-small package that supports high performance and miniaturization represented by mobile devices.
LAPIS Semiconductor develops based on the packaging technology cultivated for its own semiconductor devices, develops the latest package foundry services, and strongly supports customers' excellent product development.
Ultra-small and lightweight! 10% of mounting area and 10% of weight * 1 Revolutionary small package* 1: Compared with conventional 100-pin TQFQ
256 0.5 0.26 5
25 0.5 0.03
Realized 0.3mm typ. Thickness (0.2mm typ. Thickness is under development)
Since the device surface is sealed with resin, it can be mounted with a batch reflow device like a conventional package.
Excellent reflow resistance (JEDEC level 1) achieved by material / process technology.
Excellent electrical characteristics can be realized by controlling wiring width, wiring length, multilayer wiring, etc.
(Microcontroller, power supply IC, ASIC, sound source IC, RFIC, memory such as EEPROM, etc.)
