LMK04832: Management method according to moisture sensitivity level(s)

JH Shin
Guru 11100 points
Part Number: LMK04832

Hello,

Please provide a user guide document on how to manage according to the Moisture sensitivity level(s) of LMK04832NKDR.

My customer would like to know detailed information about when the LMK04832NKDR should be baked

Thank you.

    JH,

    According to the packaging information, LMK04832 is an MSL3 device, with 168hrs (7 days) floor life. In consultation of Reference Conditions for Drying Mounted or Unmounted SMD Packages table in IPC/JEDEC J-STD-033C (table 4-1), I find that for LMK04832NKDR, with thickness > 0.5mm and <= 0.8mm at MSL3, there are several recommendations depending on the temperature used and the floor life counter:

    125 °C +10/-0 °C, <5% RH 125 °C +10/-0 °C, <5% RH 90 °C + 8/-0 °C, ≤5% RH 90 °C + 8/-0 °C, ≤5% RH 40 °C +5/-0 °C, ≤5% RH 40 °C +5/-0 °C, ≤5% RH
    Exceed floor life > 72 hr Exceed floor life < 72 hr Exceed floor life > 72 hr Exceed floor life < 72 hr Exceed floor life > 72 hr Exceed floor life < 72 hr
    4 hr 3 hr 16 hr 13 hr 4 day 3 day

    Note that the 40 °C conditions, if tightly controlled, are applicable to tape and reel processes (including LMK04832NKDR while still in reel) - but exceeding 40 °C can cause material property changes in the reel which can affect the semiconductor material. The other conditions are only applicable to exposed material that has been separated from its original packaging.
