much glue as when the part is placed it may "squash" the glue underneath the
soldering tabs of the component. Carefully place the part into position, and
when the glue dries, solder the connection.
It is also important to note that the installation of integrated circuits has be-
come more challenging for hobbyists and experimenters. On the bright side,
the L band transmitter we are about to construct would be almost an impossi-
ble to construct with any repeatability with conventional thru hole components,
with ever miniaturizing circuitry we can offer this as a "works every time " kit. It
is, however, considerably more challenging that our simpler kits, and will take
some degree of expertise in hand assembly to complete the project. Read thru
this manual carefully before proceeding, as once you begin to build you will
not be able to receive full credit on return, and we do offer this as a wired and
tested product as well.
Pay particular attention to "time and temperature" of your soldering technique.
You should be able to perform quality solder connections in a shorter amount
of time since there is not as much of a heat "sink" due to large wires on the
components.
OOPS, I bridged that connection! This can be a common complaint in surface
mount assembly. We recommend that you use a solder braid or wick to re-
move any excess solder, usually this can be done without removing the com-
ponent.
RAMSEY "Learn-As-You-Build" KIT ASSEMBLY
There are solder connections on the DAP25 printed circuit board. Therefore,
PLEASE take us seriously when we say that good soldering is essential to the
proper operation of your discone antenna kit!
•
Use a 25-watt soldering pencil with a clean, sharp tip.
•
Use only rosin-core solder intended for electronics use.
•
Use bright lighting; a magnifying lamp or bench-style magnifier may
be helpful.
We have a two-fold strategy for the order of the following kit assembly steps.
First, we install parts in physical relationship to each other, so there's minimal
chance of inserting wires into wrong holes. Second, whenever possible, we
install in an order that fits our "Learn-As-You Build" Kit building philosophy.
This entails describing the circuit that you are building, instead of just blindly
installing components. We hope that this will not only make assembly of our
kits easier, but help you to understand the circuit you're constructing.
For each part, our word "Install" always means these steps:
