Migrating fat also proved to induce a more pronounced swelling than the same amount of
absorbed moisture.
The observation that current weathering methods do not apply moisture sufficiently to properly simulate end-use conditions or behavior leads to the question, how much
absorbed moisture is appropriate for these test methods?
The company's systems prevent the product from coagulating, breaking down, corroding or from being susceptible to mould or bacterial growth as a result of
absorbed moisture.
Lead-free soldering, with its higher temperature profiles, can exacerbate the condition, as parts that have
absorbed moisture are prone to popcorning when ramp rates are too fast or peak temperatures too high.
The
absorbed moisture is removed from the element at a temperature of 110[degrees]C or less to regenerate the element.
This condition has been reported primarily in vehicles operated in mountainous regions, and on vehicles that have been in service for a minimum of one to two years and where the brake fluid has
absorbed moisture from the air, lowering its boiling point.
5-W Power PLCC-4 LEDs can be kept in the open air (30 C, 60 percent relative humidity) for up to four weeks after being removed from its sealed package without the need to remove
absorbed moisture.
Once equilibrium was reached, the difference in
absorbed moisture was measured.
To drive off
absorbed moisture, another specimen was baked at 125[degrees]C for 4 hours prior to underfill.
If not appropriately dried prior to molding,
absorbed moisture can turn to steam and harm adhesion at the interface of the two materials.
For manufacturers, this rating means that the ASMT-SWBM can be kept in the open air (30 degrees C, 60 percent relative humidity) for up to four weeks after being removed from its sealed package without the need to remove
absorbed moisture.
The chloride on the affected component would not have been so apt to cause a failure if the WOA flux residues had not
absorbed moisture from the air.
