ES9033 Datasheet Information

Reflow is allowed 3 times. Caution must be taken to ensure time between re-flow runs does not exceed the allowed time by the moisture sensitivity

label. If the time elapsed between the re-flows exceeds the moisture sensitivity time bake the board according to the moisture sensitivity label

instructions.

Manual

Allowed up to 2 times with maximum temperature of 350°C no longer than 3 seconds.

Table 23 – RPC-1 Classification reflow profile

All temperatures refer to the center of the package, measured on the package body surface that is facing up during assembly reflow (e.g., live-bug).

If parts are reflowed in other than the normal live-bug assembly reflow orientation (i.e., dead-bug), Tp shall be within ±2°C of the live-bug Tp and still

meet the Tc requirements, otherwise, the profile shall be adjusted to achieve the latter. To accurately measure actual peak package body

temperatures, refer to JEP140 for recommended thermocouple use.

Reflow profiles in this document are for classification/preconditioning and are not meant to specify board assembly profiles. Actual board assembly

profiles should be developed based on specific process needs and board designs and should not exceed the parameters in Table RPC-1.

For example, if Tc is 260°C and time tp is 30 seconds, this means the following for the supplier and the user.

For a supplier: The peak temperature must be at least 260°C. The time above 255°C must be at least 30 seconds.

For a user: The peak temperature must not exceed 260°C. The time above 255°C must not exceed 30 seconds.

All components in the test load shall meet the classification profile requirements.
