9.5.2.2 Soldering and Handling Recommendations (PicoStar Variant)

The OPT4001 is a small device with special soldering and handling considerations. See Section 9.2.1.2.1 for implications of alignment between the device and the cutout area. See Section 9.5.1 for considerations of the soldering pads.

If the OPT4001 must be removed from a PCB, discard the device and do not reattach.

Note that excessive heat can discolor the device and affect optical performance.

As with most optical devices, handle the OPT4001 with special care to make sure that optical surfaces stay clean and free from damage. See Section 9.3 for more detailed recommendations. For best optical performance, solder flux and any other possible debris must be cleaned after soldering processes.
