Important:
On all the soldering you do, you will use the same technique. You tack a single tiny point
first and, then check to see that it is square and aligned with the registration lines and
other notes. It is easy to re-heat the joint and adjust the alignment when there is only a
single point. Then you tack the other pads, before you do the finish soldering.
First, check that the pins on the female header are bent 90º, and correct if necessary. Solder the 2x2
female right angle header to the left contact holder on the side with the silkscreen.
Solder only one pin and
check for it being flush and parallel to the surface of the board,
as shown in the graphic below. This is
necessary so it aligns with the internal contacts of the transceiver. Solder the rest of the pins and trim flush
with the back of the board.
Next in the assembly, are the two
contact holders
mated with the
support
. Using the 4-40 x 1” long
screw, assemble the two contact holders as shown in the figure below. You must adjust the nuts so that the
support just does fit between the two contact holders, flush with the front.
