DS90UB947-Q1: Inquiry about reflow conditions

Part Number: DS90UB947-Q1

Hi,

My customer is using the two products below.

SERIALIZER : DS90UB947TRGCRQ1

DESERIALIZER : DS90UB948TNKDRQ1

The reflow conditions for both products are not listed in the datasheet.

Please tell us about the reflow conditions.

Thanks.

Regards,

MJ

    Hi MJ,

    Thank you for reaching out to us. I do not have a particular reflow profile for UB947 or UB948. However, the reflow peak temp and MSL should be available if you need. You are free to use assembly house reflow profile(s) as long as you conform “Maximum dwell time @ maximum process temperature” per IPC/JEDEC J-STD-020D. You can refer to the section 5.2 in the apps note.

    Hi, Aaron

    Thank you for your answer.

    The figure below is the reflow condition actually applied to production.

    Please check if there are any problems.

    The material applied to the production is Pb-Free.

    Thanks.

    Regards,

    MJ

    Hi MJ,

    Thanks for sharing the profile. As I mentioned on previous posted, there is no issue if you are using the standard reflow as long as you are not exceeding the maximum temperature. Time within 5 °C of the specified classification temperature; Sn-Pb Eutectic Assembly-20 seconds maximum; Pb-Free Assembly-30 seconds maximum.
