SCA3000 Assembly Instructions

1.

Apply the solder paste onto the PWB land pads. The paste can be applied by two different

methods.

-

Manual solder paste printing through a stencil with normal openings designed for the

SCA3000 component.

-

Needle dispensing of solder paste manually onto the PWB pads. VTI recommends use

of a microscope in manual solder paste dispensing. Dispensing needle tip size can be

0.12"-0.16".

2.

Place the component gently on top of the solder paste. To avoid solder bridging, push only very

gently on top of the component.

3.

i) Melt the solder paste by putting the part through reflow oven or ii) by using soldering iron.

When using soldering iron, do not touch the package plastic body, soldering iron should touch

only the extension in the PWB's land pad through that the heat should be conducted to melt the

solder paste and then form the solder joint to the component lead. See figure 11 above for

details.

Environmental Aspects

VTI Technologies respects environmental values and thus its MID packaged pressure sensors are

lead-free and RoHS compatible. VTI Technologies’ sensors should be soldered with lead-free

solders in order to guarantee full RoHS compatibility.
