Rework procedure

Due to the large mechanical tolerance of the power amplifiers, the following procedure
is necessary:
1 Put the power amplifier into the RJ-21 rework jig. The PA should be placed in the
best fit location, this is determined by placing it in the largest location first, if
this is to large reposition the PA in the next size location. This should be carried
out until the best fit location is found.
2 Once the best fit location has been found, leave the PA there and put the stencil
on top of the jig and PA.
3 Put soldering paste on the PA properly.
