This device is constructed using a unique set of packaging
techniques that impose a limit on the thermal profile the device
can be exposed to during board-level solder attach and
rework. Maxim recommends the use of the solder profiles rec-
ommended in the industry-standard specification, JEDEC
020A, paragraph 7.6, Table 3 for IR/VPR and Convection
Reflow processes. Preheating, per this standard, is required.
Hand or wave soldering is not recommended.
