2) Flexible PC board design

Positions of connectors on the FPC
FPC consists of polyimide, copper foil and bond layer. Each contraction rate of
those material by heat is different so that warp of FPC may occurred and may
cause poor soldering. Therefore, positioning connector on FPC minimizing
influence of warp.
■
Example of Assist carrier (ShinEtsu Polymer Co., Ltd)
In case of a one-sided FPC board, warpage is
more likely to occur if a pattern is laid in a line,
or if the copper foil is applied over the entire
FPC board for noise-prevention purposes.
It is difficult to keep FPC
flat because FPC is flexible

Example of carrier for mounting process
- Magic resin (Daisho Denshi)
- Silicon gum board
(Mitsubishi Resin)
- Assist carrier
(ShinEtsu Polymer Co., Ltd)
When mounting connector, it is
recommended that the usage of carrier with
adherent surface for mounting process to keep
FPC even.
