Package	Package Capacitance
20 SSOP	2.6 pF

28 SSOP	2.8 pF

Solder Reflow Peak Temperature

The following table lists the minimum solder reflow peak temperature to achieve good solderability.

Table 31. Solder Reflow Peak Temperature

Package	Minimum Peak Temperature*	Maximum Peak Temperature
20 SSOP	240oC	260oC
28 SSOP	240oC	260oC

*Higher temperatures may be required based on the solder melting point. Typical temperatures for solder are 220 ± 5oC with Sn-Pb or 245 ± 5oC with Sn-Ag-Cu paste. Refer to the solder manufacturer specifications.
