... Since the WLCSP package has a structure that a silicon wafer is exposed, if light (such as sunlight) hits the wafer, the device may malfunction (leak current increase etc.) due to electric charge internally generated by the photoelectric effect. * Please mount the package without underfill because temperature correction may not be normally performed when mounting YAS529 on a board. 8 ...
