Above are various examples of components that can be
mounted on our N8106 boards. Each board (10 per strip) has been v-scored so it
can be easily snapped loose from the strip. The following procedure covers the
step by step method to separate boards from the strip:
Decide how many boards are needed for a particular
application. For example, for lighting, often times it is desirable to have
a resistor-LED combination that can be mounted inside a structure or
railroad rolling stock such as a passenger car. In this case a 2-board
section should be removed from the strip.
Using a sharp scalpel blade or single-edged
razor blade, slice the Kapton tape on the back of the strip across the strip
directly over the v-score between the second and third board.
Once the tape is cut, grasp the strip holding the #2
and #3 boards and bend the strip. The boards will "snap" and separate at the
v-scored groove between them
Now this 2-board section can be gently held by the
ends in a bench vise (with padded jaws) in preparation for mounting
components to the boards.
We recommend lightly tinning the solder pads on the
boards before mounting and soldering components. This makes attaching the
components much easier and quicker. This is especially beneficial when
mounting thermally sensitive devices such as LEDs.
We strongly recommend using a
low-temperature soldering iron with a needle tip and low-temperature solder
for all soldering operations with these boards.
Once the pads have been pre-tinned place a small bit
of solder on the tip of the needle tip of the iron. Using tweezers, pick up
the component you want to mount on the board so that one end of the
component can be placed on one of the solder pads with the component
centered between the two pads. While holding the component in position,
carefully touch the pre-tinned pad with the tip of the iron, allowing the
small bit of solder on the tip to reflow the solder on the pre-tinned pad.
This will be a quick operation so minimal heat will be transferred to the
component and a shiny bright solder joint should result.
Now that one end of the component is soldered in
position, repeat the above step for the other end of the component and other
pad. Now that component is securely soldered to the mounting board.
If the component you mounted is an LED, be sure to
remember that LEDs are polarity so it is important to know which end is the
anode (+) and which is the cathode (-).
Once the second component has been soldered in
position you now have a LED resistor combination that can be used for a
lighting project. Since the LED and resistor must be wired in series with
each other, a small jumper wire can be connected from one hole at the end of
one pad to the appropriate hole one the adjacent board containing the other
Now power wires can be attached to the other pads
using the holes located near those pads and the circuit will be complete.
Be sure to test the circuit before mounting it in
When you are ready to mount the two-board circuit,
simply peel off the protective Kapton from the back side of the mounting
boards and stick them in position in your project.
