An energy conversion system may comprise a substrate including a first conductive trace and a second conductive trace electrically isolated from the first conductive trace. A housing may be coupled to the substrate. An ignition compound may be located in the housing. A solder may be thermally coupled to the ignition compound such that ignition of the ignition compound melts the solder. The housing may be configured to output the solder onto the first conductive trace and the second conductive trace.
