BULLETIN # 1055
MODEL: All
SUBJECT: Power Module Heat Sink Compound
Symptom: Several current and past model transceivers do not use Heat
Sink Compound on the power modules. Our engineering department determined
through testing, that those models with fine castings or machined areas
under the power module do not really require its use. Several service
facilities and customers have questioned this and are concerned that
this could eventually cause failure of the power module(s).
Corrective Action: In order to ameliorate any anxiety and to increase your
confidence, our engineers recommend that you use Silicone Heat Compound
whenever replacing any of these devices or whenever they must be lifted
for service of other components on the board. Our production lines will
begin using this compound again as added protection for these devices.
Parts Required:
