3.4 Mounting the Violin
3.4.1 Mounting the Heatsink
The Violin dissipates its heat by natural convection, up to loads of 500 W. For higher
output loads, the amplifier should be mounted on an additional heatsink or cooled by
fan. There are two 4.5 mm holes in the base plate for mounting an additional heatsink
(see
Figure 3-1 ).
3.4.2 Mounting on the PC Board
When mounting the Violin on a PC board, four screws (in addition to the solder pins)
may be installed to provide a mechanical connection. It is important to provide a spacer if
any components are located above the amplifier. Failure to do so can warp the PC board
or puncture the amplifier case. When selecting screws, the following specifications
should be used. If a spacer has been added, the screw length must be calculated to
penetrate the case by no more than 2.6 mm.
Screw Type: Phillips Pan Head Self-tapping (for plastic) screw – Nickel-plated Steel.
Meets standards ISO 1478, EN 21478, or DIN 7970.
