Primary datum C and seating plane are defined by the spherical crowns of the solder balls. Dimension
is measured at the maximum solder ball diameter, parallel to primary datum C. All dimensions and
tolerances conform to ASME Y14.5 – 2009.
Figure 10.4. Physical layout of the A111 sensor, bottom view.
The bottom view shows 50 solder balls. The pitch of the BGA balls is 500 µm, the ball diameter is 300
µm ±5 µm and the collapsed ball height is 0.244 ± 0.050 mm.
9.1 Recommended Reflow Profile
A111 sensor is a Moisture Sensitive Devices (MSD) in accordance to the IPC/JEDEC specification.
The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required.
A111 sensor is rated at MSL level 3. Soldering process qualified during qualification with
“Preconditioning MSL 3: 30°C. 60%r.h., 192h, according to JEDEC JSTD20”.
Acconeer A111 sensor is compliant with Restrictions on Hazardous Substances (RoHS) and it is
qualified for soldering heat resistance according to JEDEC J-STD-020.
