Hi,
So, I have a board which uses a LIS344 accelerometer. This is a LGA16 package and I'm having some trouble to reliably solder this.
I have tried two different foot print. One, where the solder pads extend outside the package to be able to solder using the normal soldering iron. Then, a second where I made the footprint exactly as the pads (I made a small mistake, ST recommends a footprint which is +0.1mm x and y to the pads).
The last footprint seams to solder nicely, the component re-align it self when the solder starts flowing(using hot-air on the opposite side of the board). But, the connections are not good, I usually end up with just one output working while the others seams to be froozen.
Anyone have any suggestions?
