PLCC Drying
Whenever Vapor Phase or Infra-
red Reflow Technologies are used
to mount the PLCC packages,
there is a possibility that
previously absorbed moisture,
heated very rapidly to the reflow
temperatures, may cause the
package to crack from the
internal stresses. There is a
reliability concern that moisture
may then enter the package over
a period of time, and metal
corrosion may take place,
degrading the IC performance.
To reduce the amount of
absorbed moisture and prevent
cracking, all of the PLCC ICs
should undergo one of the

parts must then be mounted
within 48 hours.
If the parts are not mounted with-
in 48 hours, they must be re-
baked.
The total number of baking cycles
must not exceed two. If the ICs
are baked more than twice,

Hewlett-Packard cannot guaran-
tee the performance and
reliability of the parts.
Neither bake cycle can be per-
formed in the standard shipping
tubes. The ICs must be baked in
an ESD safe, mechanically stable
container, such as an aluminum
tube or pan.
