Question

Is the sensor’s protective cover replaceable?

Answer

The cover is designed to be compatible with normal convection reflow soldering. The cover is not designed to be replaced. We have seen some customers that use excess heat in soldering and the cover shrinks to the point that it is no longer effective. Some customers have had issues with some conformal coating material drying between the cover and the protective tape used while conformal coating is applied. This results in the protective cover peeling off with the tape when the tape is removed after the conformal coating dries. Both of these issues should be avoided. While the cover can be replaced with care to avoid sensor surface contamination, the recommended rework procedure for a device where the cover has been damaged or has peeled off is to replace the device.
