9.3.3 Reflow Profile

Many traditional optocouplers have limits on the peak temperature of reflow soldering due to device construction. Opto-emulators benefit from TI's packaging technology and can withstand up to three reflow cycles. These integrated circuit packages are classified for moisture and reflow temperature sensitivity according to the current IPC/JEDEC J-STD-020 standard.

The peak reflow temperature is specified according to the package thickness and plastic volume. The Pb-Free Process-Classification Temperatures (Tc) table in the IPC/JEDEC J-STD-020 standard lists the temperatures for lead-free processes, which are shown in Table 9-2.

Table 9-2 Peak Reflow Classification (Tc) Based on Package Dimensions
Package Thickness Volume < 350mm3 Volume 350 – 2000mm3 Volume >2000mm3
< 1.6mm 260°C 260°C 260°C
1.6mm – 2.5mm 260°C 250°C 245°C
>2.5mm 250°C 245°C 245°C

The reflow profile shown in Figure 9-8 can be used with a typical range for the customer peak reflow temperature (Tp) of 235°C to 250°C. The peak reflow temperature (Tp) must not exceed the classification reflow temperature (Tc) shown in Table 9-2 and Figure 9-8.
