SAW Soldering Profile
Many TriQuint SAW product customers request solder profile information for soldering either surface
mount or through hole packages to their PC boards. Since there are many different methods and
equipment types used in the soldering process, the following information, shown below in
Figure 1 and Table 1, should be utilized as a recommended guideline only.
