- TI does not have a recommendation for any specific conformal coat or underfill product.
- In some temperature ranges these materials can be detrimental if the conformal coating or underfill product has a mismatched CTE vs. solder joint (Z axis). This mismatch combined with modulus of the material at certain temperatures can actually shorten the service life.
- Due to this the customer should evaluate the performance of the underfill/conformal coating materials at an assembly level for the intended mission profile.
