RECOMMENDATION FOR SOLDER PAD PATTERN
The solder pad pattern should be designed by customers because it depends on the electrical
performance of the customers’ system. Following is an example of solder pad pattern which is used in
OKI’s package evaluation board. Please be noted that this is for reference purpose only.

Please pay attention to the following items to maintain electrical performance.
(1) Metal mask pattern for cream solder should be 25 µm smaller on each side. Metal mask is 0.15 mm in
thickness.
(2) As the impedance of Tx, Rx, ANT is designed for 50Ω, please consider this for the design of mother board.
