EMW3239

1.1

Pin arrangement

EMW3239 has 41 pins in two rows (1x20 and 1x21) with 0.8mm pitch. Stamp hole package interface design

is used in EMW3239 (as shown in figure 3) to simplify debugging and disassembling for developers, as well as

offering varied selection. Also it is benefit for SMT patch and hand-welding.

Solder mask openness has the same size with land. The width of steel mesh is suggested to be 0.12mm to

0.14mm in SMT.
