02-2. Precautions for board design
1) Circuit design
(1)When designing the terminal foot pattern, check the latest specifications and
examine the recommended foot pattern and dimensions of the metal mask opening.
The current recommendations are indicated on pages 13 and 14.
(2)This connector is provided with soldering metals for preventing solder from
peeling off the terminal.
Make sure to design a foot pattern for the holding metal.
(3)Pay attention to 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 or poor soldering of the terminals.
①Thin and extend the tip of the foot
pattern before creating a through-hole.
②Prevent solder from reaching the land
by using a coverlay or resist.
