Please consider the following points when providing a through hole by extending
the foot pattern.
If a through-hole is created simply by extending
the foot pattern by the same width, solder is
absorbed into the through-hole during the reflow
process, which may cause defective soldering of
the terminals.
①
Thin and extend the tip of the foot
pattern before creating a through-hole.
②
Prevent solder from reaching the land
by using a cover lay or resist.

Please consider the following point as a pattern
peeling preventive measure when removing the
connector.
-
Make the foot pattern length longer than the
coverlay opening.
In general, at least 0.3 mm.
(8) Foot pattern dimensions indicated in the specification
intended to achieve the minimum area on the premise
that the reflow-soldering process is used.
For manual
soldering or for ensuring solder reworkability, make
a longer pattern at the terminal tip.
In general, 1/3 the
terminal pattern
width.
- Secure space for applying the soldering
iron tip.
Terminal looseness and unwanted
solder creep are preventable by
applying the soldering iron tip here.
