3) Support plate design
Select a support plate with an appropriate thickness and hardness to prevent
solder or the pattern from being removed during unmating of the connector.
(1)
It is recommended to use glass-reinforced epoxy plates, which can easily
provide adequate hardness.
(2)
When using a polyimide material to prevent lint from being generated,
follow the rules below.
- Select a plate as a thick as possible.
(Generally, plates of 0.2 mm thick or more may be used.)
-
It is recommended to use a hard adhesive (epoxy-base) to bond the plate to
a flexible PC board.
- Two-ply support plates bonded with epoxy adhesive are harder than single
support plates of the same thickness.
(3)
As a rule, always cut the support plate materials into pieces in the same
direction, otherwise, some plates will warp during reflow soldering and
cause poor soldering.
(
It is recommended to cut the material in the direction of the reinforcing
fiber.
)
(4)
In order to achieve greater device thinness, methods that use metals such as
stainless steel are used for support plates when extremely thin support plates
are desired.
(5)
Design the
support plates so that the edges are 0.5~1.0 mm or more
outside
the tips of the foot pattern traces in order to protect the soldered joints of the
connector terminals from stress caused when the connector is unmated or
when the flexible PC board is bent.
(6)
Foot pattern design
When using thin support plates, take the following
measures to improve the support’s effectiveness.
- Design the foot pattern traces longer than
the coverlay opening edge. Normally, the
distance is set to approx. 0.3 mm. For
greater support, it is recommended that the
distance be
at least doubled
