WLCSP (wafer-level CSP)

Wafer-level chip-scale package — bare-die balls.

IPC land pattern WLCSP
Also known as WL-CSP, chip-scale package, DSBGA

A wafer-level chip-scale package is essentially the bare die with solder balls directly on it, at 0.4–0.5 mm pitch. Tiny and demanding: precise stencil, reflow and gentle handling — no package protects the die.

Working with it

Hand-soldering Reflow / hot-air
Commonly holds Processors, memory, fpgas and sensors
Note Leadless: needs solder paste and reflow or hot air (contacts sit under the body).
