Custom MMIC Design Services recommends that the user develop the land pattern that

will provide the best design for proper solder reflow and device attach for their specific

application. Please review CMDS Application Note AN 105 for a recommended land

pattern approach.

Recommended Solder Reflow Profile

Custom MMIC Design Services recommends screen printing with belt furnace reflow to

ensure proper solder reflow and device attach. Please review CMDS Application Note

AN 102 for a recommended solder reflow profile.
