Also Offering RoHs Compliant Equivalent Parts Surface Mount Hyperabrupt Varactors Mounting Information The illustration indicates the recommended mounting pad configuration for the SOT-23 package. Solder paste containing flux should be screened onto the pads to a thickness of 0.005- 0.007 inches. The plastic package is placed in position, firmly adhering to the solder paste. Permanent attachment is performed by a reflow soldering procedure during which the tab temperature does not exceed +275 C and the body temperature does not exceed +250 C, for standard models and +260 C for the RoHS compliant devices.
