Precautions when providing a pattern and through-hole inside the prohibited
area
As shown below, the header’s post extends down to the bottomface of the molded
part, and the post extends horizontally beyond the molded part becomes the
terminal.
From this structure,pay attention to the following points.
①
When providing an uninsulated through-hole, make sure to design it so that it
does not interfere with adjacent terminals.
②
It is recommended that the patterns not be interfered in contiguous contacts.

Precautions when providing an insulated through-hole in a prohibited area
As shown below, the header’s post extends down to the bottomface of the molded
part, and the post extends horizontally beyond the molded part becomes the
terminal.
If an insulated through-hole is placed in the prohibited area, the gap between the
pattern and connector terminal becomes wider, which may result in poor soldering.

●
Key point.
We recommend that you provide a through-hole closer to the center, out of the prohibited area.

and molded part
A gap can be
absorbed by a step
between the molded
part and the
