To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module.

Once the original package is Surface Mount Information broken, the floor life of the product at conditions of  30°C and 60% relative humidity varies according to the MSL rating Pick and Place (see J-STD-033A). The shelf life for dry packed SMT packages The ABXS001 Open Frame modules use an open frame will be a minimum of 12 months from the bag seal date, construction and are designed for a fully automated when stored at the following conditions: < 40° C, < 90% assembly process. The modules are fitted with a label relative humidity. designed to provide a large surface area for pick and place 300 operations. The label meets all the requirements for surface Per J-STD-020 Rev.

The module weight has been kept to a minimum by 50 using open frame construction. Variables such as nozzle size, tip style, vacuum pressure and placement speed should be 0 considered to optimize this process. The minimum Reflow Time (Seconds) recommended inside nozzle diameter for reliable operation is Figure 35. Recommended linear reflow profile using 3mm. The maximum nozzle outer diameter, which will safely Sn/Ag/Cu solder. fit within the allowable component spacing, is 7 mm. Bottom Side / First Side Assembly Post Solder Cleaning and Drying Considerations This module is not recommended for assembly on the Post solder cleaning is usually the final circuit-board bottom side of a customer board. If such an assembly is assembly process prior to electrical board testing. The result attempted, components may fall off the module during the of inadequate cleaning and drying can affect both the second reflow process. reliability of a power module and the testability of the finished circuit-board assembly. For guidance on Lead Free Soldering appropriate soldering, cleaning and drying procedures, refer to Board Mounted Power Modules: Soldering and Cleaning The modules are lead-free (Pb-free) and RoHS compliant and Application Note (AN04-001). fully compatible in a Pb-free soldering process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability. Pb-free Reflow Profile Power Systems will comply with J-STD-020 Rev. D (Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. This standard provides a recommended forced-air-convection reflow profile based on the volume and thickness of the package (table 4-2). The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Fig. 35. Soldering outside of the recommended profile requires testing to verify results and performance. MSL Rating The ABXS001 Open Frame modules have a MSL rating of 2a Storage and Handling The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater.
