How does ramp up/cool down rate affect the properties Ablestik products?
Differences in ramp up rates can have an impact on the level of voiding in the cured adhesive. A faster ramp rate can induce voiding, whereas a longer ramp may prevent voiding. Effect of ramp rate varies with the chemistry of the material. Consult the material’s Technical Data Sheet for specific cure profile recommendations. Differences in cool down rate may induce different stress levels in the package. The thermal shock of fast cooling from cure temperature to ambient may have a negative impact on the reliability performance of the adhesive and the final package.
