PICKING TOOLS
The MS7212-A2 sensors have a topside glass cap (1.05 x 1.18 mm ) and a backside glass (1.73 x 1.18 mm ).
The pick and place tool has to be of a soft material as rubber (Hardness 78-97 Shore A). Its external size must
fit the glass cap. Successful tests were done with some tools of SPT (see SPT drawing and references bellow).
