The next step is to secure the switch to the double-sided tape on the aluminum bracket provided. Route
the switch wires along the top frame of the fan. Use a cut piece of the supplied double-sided tape to
hold the switch-bracket in place. This tape is only used to place the switch in position. The compression
of the lid to the frame holds the switch in place during operation. Connect speaker wire and place the lid
in position and install screws. Install the BHI label, read the BHI manual and enjoy.

Explanation of SMT: When SMT boards are assembled the parts are laid onto pads with solder paste
already applied to the pads. The paste holds the parts in place. The boards then travel through an oven
with multiple zones, which step the entire assembly up to the reflow solder temperature and then zones
to cool the board assembly. At the reflow point 100s to 1000s of components are all soldered in the
same few seconds. This process produces low mechanical stress and controlled solder amounts. When
complete, this process produces highly reliable and rugged assemblies.
SMT, however, does not do well with localized heating or mechanical stress, especially if the two are
combined. When working with SMT components and PCBs this must be kept in mind. Whether you are
doing a mod, an installation like this, or a repair, this needs to be understood. The technology is not
designed for localized heating or mechanical stress. Because of this many radio service manuals
dedicate a few pages on SMT repair guidance. I have lost track of how many customers have sent me
radios to repair that, unfortunately, have been damaged by not using the proper tools or proper
technique.
