BGA substitute

[nattar]

Hi All,
I was wondering if there is any alternative to BGA type connector?
Bridging is our main problem after placement and reflow.
Thanks,

The problem should not be the BGA, but in the process and preparation.

There is a temperature and duration needed to properly apply the BGA, it
takes some trial and error with samples, based on the type of BGA package
and the circuit board and its thickness.

The technology is solid, so it should work.

The alternative is the BGA socket, but then the device may not perform right
at high speeds.

Change your attachment process whatever it is. After number of failed
attachments done by one previously reliable assembly house I switched to
another. Problems went away.
