Hi, all.

I'm working on a project (AHRS) where I will soon need to solder some Analog
ADXRS150 gyros to a board. As you may or may not know, these little buggers
only come in a BGA-32 ball-grid array surface mount package. Do any of you
have experience soldering this or similar packages at home?



Here's what I'm thinking of doing:

1)       Place a grid of vias lined up with the balls on the bottom of the
package.

2)       Put solder paste on top of each via, and slap the gyro on top

3)       Carefully heat each via until the solder melts

4)       Do this several times for each ball, to make sure that the solder
has fully melted and the package is settled.



The main issue I see with this method, is the fact that solder bridges could
be forming under the package, and I would never know about them, until I
smelled the magic smoke coming out. Ideas?



I don't have any previous experience with home-SMD, so I'm a little
reluctant to try the toaster-oven method, at least with these expensive
little buggers. I'd kick myself for days if I baked one.



Thanks!



- Robert
