Qualify improved mold compound to achieve better moisture sensitivity level (from MSL 4 to MSL 3) and 3. Qualify new leadframe base material to improve matching of coefficient of thermal expansion Parts Affected: HFBR-2505CFZ HFBR-2505CZ HFBR-2521Z HFBR-2522Z HFBR-2523Z HFBR-2523Z-00A HFBR-2524Z HFBR-2531Z HFBR-2532Z HFBR-2533Z HFBR-2541Z QFBR-2548Z QFBR-2551Z QFBR-2573Z QFBR-521RZ QFBR-R521Z QFBR-R531Z QFBR-TR04Z QFBR-TR05Z QFBR-TR10Z QFBR-5591Z QFBR-5592Z QFBR-5594Z QFBR-5595Z 4. Qualify alternate photo diode supplier and improved mold compound: Parts Affected: QFBR-R518Z HFBR-2510Z HFBR-2526Z HFBR-2536Z Reasons for Changes: 1. Improved mold compound: to improve moisture sensitivity level from MSL 4 to MSL 3 and to harmonize the mold compound in use. The improved mold compound has been qualified and used in other Avago products since 2007. 2. New leadframe base material: to improve the matching of coefficient-of-thermal-expansion. Lead frame layout remains unchanged. All other 650nm transmitters from Avago have been qualified and shipped with this lead frame material for more than 15 years. 3. New photodiode: to qualify alternative photo diode supplier. The alternate supplier and its photo diode is already qualified and used in other Avago products since 2007. Effect of Change on Fit, Form, Function, Quality or Reliability: Reliability qualifications have been performed to ensure product reliability before the implementation date. Detailed product characterizations were performed to ensure product compliance to datasheet. Effective Date of Change: The approximate dates for sample availability, qualification completion and effective date of change for the above changes are shown in the table below. Timing of shipment, on or after the Target Date of the changed part will vary by part number depending on customer demand, and inventory levels.
