important to ensure that the on-board connectors are installed ‘square and plumb’ to the PC
board surface.
BEFORE YOU START
Before getting started with building the Hilltopper 20, take some time to organize and
familiarize yourself with the parts provided and check them against the Parts List. Building over
a cookie sheet is recommended to minimize parts being lost. To prevent static damage, it is
recommended that the ICs not be removed from their anti-static packaging until you are ready
to install them. If parts are missing in your kit, send an email to the Hiltopper kitter listed at
4SQRP.com. He will promptly provide replacements.
It is helpful to acquire the necessary tools and supplies before beginning. These include:
*Soldering iron – 20 to 30W, preferably thermostatically controlled.
*Fine 60/40 rosin core solder
*Diagonal cutters
*Needle-nose pliers
*Fine file or emery board
*Flat blade and Phillips screwdriver
Schematic and Component Placement diagrams are provided as part of documentation package.
It is highly recommended to print a copy for reference during construction. As you build, you can
check off each construction step as you complete them in order. When you think you are done,
you can check the list to verify that all of the parts have been installed.
Snap off the enclosure sides from the sides of the two main boards. The boards are scored with
a V-groove so that they break free readily. Once separated, lightly sand the rough edges of the
breaks until smooth.
Further details may be found in the grouped assembly sequences.
