1.2.3 PWB designing
Design PWB layout properly so that front, back and side fillets are formed.
By applying the recommended PWB layout, optimum retention force can be obtained between
connector and PWB.
Solder wicking and flux penetration could occur by applying different PWB layout from the
recommended. Please contact us for the different PWB pattern from the recommended PWB layout.
Although standoff is provided, interference to the connector body by pattern, via hole and solder
resist beneath the connector may cause solder defects and poor fillet formation.
1.2.4 FPC designing
Diversity of coefficient thermal expansion in FPC and stiffener materials may cause FPC warpage and
mounting failure. Confirmation prior to your manufacturing is necessary.
