5 4 Manufacturing Information 4. Handling and Assembly Recommendations The products are not hermetically sealed, and should not be exposed to any liquid-based rinsing processes. IXYS Integrated Circuits Division recommends two () approaches: () the modem should be installed in a wave-soldering process that uses a no-clean soldering flux that will mostly evaporate during the normal wave-soldering processes, () the modem should be soldered in by hand after the rest of the card is wave-soldered. 4. Reflow Profile These products have a maximum solder temperature as shown below. Device Maximum Temperature CYG000 / CYG0 / CYG00 60 C 4.3 Mechanical Dimensions 4.3. CYG (.070) 0.6 (0.400).
