The components in this catalog are
manufactured with ceramic dielectrics. To minimize possible damage to the
components, during installation, the recommendations below should be followed. For
information concerning other installation requirements or component
modifications, please consult LCA customer service at Email: Sales1@lcamic.com.
General Recommendations
Handling: Excessive force or direct impact to the
component may result in breakage. Lead bending or cutting, if necessary, should
be done with a support for the lead to prevent mechanical stress to the component.
Components with required lead modifications are available from LCA.
Lead Soldering: Use a temperature
controlled soldering iron with SN60 or SN63 RMA Flux core wire. Maximum soldering
temperature to be 500°F(260°C) with a dwell time of 3 seconds maximum. The use
of a heat sink between the component body and the solder joint is highly
recommended.
Flux Removal: Optimum flux
removal can be achieved by vapor degreasing the components immediately after
the soldering operation. Total immersion of the components is not recommended.
1) Bushing Mount Recommendations
Rotating force of installation--- When
install the filter on the septum or faceplate, should used the recommended
rotating force. This is very important, or the filter would be damaged due to
the changed shell. When install it in to the threaded hole, the maximum Install
torque should be 50% of which recommended to the nut.
Installation tool--- Hexagonal filter should be
installed with a fit drive pipe. The round should use the following method
(should not be installed with pinchers, in case the filter should be damaged).
Round filter with
slotting on the top should be presses in threaded hole use a simple special
tool.
Ground connection---In order to ensure the filter
proper functioning, the shell of the filter should be long enough to be
connected to the ground, so that provide the effective way for the
interference. Using adhesive locking is not recommended, in that case, it
should be used after the filter has been installed.
The minimum thickness of plating---The user should note that there is
tool withdrawal groove between the thread and the shell. When the thickness
which is pressed into the board less than the tool withdrawal groove, there
should be a problem exist. So, if possible, the thickness of the board should
over the length of the tool withdrawal groove.
The maximum thickness of plating---This index is used to insure
conditions include using washer; nut can completely match the tooth.
2) Solder Mount Recommendations
It
should be controlled and prevented the filter not affected by the break heat
shock result in the ceramic damaged inside the filter during soldering.
The
speed should be control at 2℃/sec when preheating temperature. In fact, there
is also successful examples that use 1.5 ~ 4℃/sec on different boards and
components. Welding materials can be SN60, SN62 or similar ones.
3) Solder Terminal Block
No
matter thread type or welding directly type, please focus on the followings:
The temperature of soldering iron
should not over 300℃,and the longest time is 3 ~ 5 sec,try best to reduce the risk of
damaging the filter by the heat shock.
Welding
materials can be SN60, SN62 or similar ones.
Using
radiator between the soldering point and the shell if possible, especially
important when welding time is longer.
How
to trim and curve block
It
should be held up while it is trimmed and not be curved within 4mm closed to
the epoxy sealed.
