A schematic diagram of the SKY65129-21 Evaluation Board is shown in Figure 11. Table 5 provides the Bill of Materials (BOM) list for Evaluation Board components. An assembly drawing for the Evaluation Board is shown in Figure 12 and the layer detail is provided in Figure 13. Since the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. Instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. For additional information on board design for thermal considerations, refer to the Skyworks Application Note, PCB Design Guidelines for High Power Dissipation Packages (document #201211). The SKY65129-21 is rated to Moisture Sensitivity Level 3 (MSL3) at 250 °C. It can be used for lead or lead-free soldering. For additional information, refer to Skyworks Application Note, PCB Design and SMT Assembly/Rework Guidelines for MCM-L Packages, document number 101752. Package Dimensions The PCB layout footprint for the SKY65129-21 is provided in Figure 14. Package dimensions for the 20-pin MCM are shown in Figure 15, and tape and reel dimensions are provided in Figure 16. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. Production quantities of this product are shipped in a standard tape and reel format.
