The improved package robustness increases floor life to 72 hours for customers. Mold Compound Physical Comparison La di on st v str Ja ie ib n/ we ut 26 d io /2 b n 0 y pe out 15 Ar rm sid 08 zli itt e :39 e A ed of U m Ja T ir bi C li sn ot Section I: Mold Compound Background The mold compound satisfies three packaging requirements for VI Chips. First, it provides encapsulation of the PCB assembly and components. Second, it provides a dielectric for voltage differences of components, terminations and pads. Third, it provides a thermal path for heat generated during the operation of the VI Chip. Mold compound plays a critical role in the MSL performance of VI Chips. Current Mold Compound The current mold compound meets all of the packaging requirements, however, it cannot provide MSL performance better than MSL6 at 245°C for all VI Chip products. Its structural modulus at room temperature is low giving it low stress and therefore good electrical performance from the stress sensitive transformer ferrite cores. Its low structural modulus at elevated temperature and moisture absorption characteristics are factors that contribute to its limited MSL performance. The new mold compound also meets all of the packaging requirements and is qualified at MSL4 245°C. Its structural modulus, adhesion and moisture resistance is higher than the current mold compound, which is needed to achieve MSL4. The new mold compound passes all reliability testing after exposure to MSL4 245°C reflow conditioning. Critical MSL Material Performance Characterization Re A more hydrophobic mold compound with excellent adhesion characteristics was needed to improve MSL performance. Moisture can weaken the interfacial adhesion and increase overall package stress, resulting in failure such as solder shorting during reflow. The new mold compound is significantly more hydrophobic than the current material; see Chart 1 below for moisture uptake comparative data.

The new compound has significantly higher shear strength than the old mold compound on both substrates evaluated, further supporting the contrast in MSL performance observed between the two materials. See Chart 2 for comparative shear test data.

The results for both tests were comparable, confirming that there was no impact to thermal performance.

These products meet the following reliability test requirements: • MSL 4 3X245°C reflow conditioning • 1,000 temperature cycles from -55°C to 125°C • 1,000 hours at 125°C • 1,000 hours at -65°C • 1,000 hours of temperature-humidity bias Details of MSL 4 Reflow Testing Re MSL 4 245°C Qualification Process Steps: 1. Units baked at 125°C for 24 hours. 2. Condition per J-STD-020D.1 using standard soak conditions of 96 hours at 30°C/60% RH. 3. Reflow 3 times using profile per J-STD-020D.1 (See Chart 5 below) 4.

Product electrical performance and reliability are not affected by this material change, allowing customers to continue to experience very high long-term field performance with Vicor’s VI Chip products.
