ASSEMBLY
DECOUPLING CAPACITOR
Particular care must be taken when connecting the device to power supply. A 47 µF tantalum capacitor must be
placed as close as possible of the MS5536C's VDD pin. This capacitor will stabilise the power supply during data
conversion and thus, provide the highest possible accuracy.
SOLDERING
Please refer to the application note AN808 for all soldering issues.
MOUNTING
The MS5536C can be placed with automatic Pick&Place equipment using a special vacuum nozzle. It will not be
damaged by the vacuum.
For a good mechanical stability, it is important to solder all contact pads. The Pins PEN and PV must be left open
or connected to Vdd. Do not connect to GND!
LIGHT SENSITIVITY
The MS5536C is protected against sunlight by the cap on front side. It is, however, important to note that the sensor
may still be slightly sensitive to sunlight, especially to infrared light sources (Light may also enter the negative
pressure port on backside). This is due to the strong photo effect of silicon. As the effect is reversible there will be
no damage, but the user has to take care that in the final product the sensor cannot be exposed to direct light during
operation. This can be achieved for instance by placing mechanical parts with holes in such that light cannot pass.
CONNECTING THE PRESSURE PORT
The best connection to the pressure port is achieved with a flexible tube fitted to the full length of the nozzle. Care
should be taken to keep the nozzle clean. The tube should be flexible enough to minimize the mechanical stress
on the module (see Fig. 10)
