Abstract

Components of a circuit on a printed circuit board <B>3</B> are protected from the effects of destructive breakdown of a component or components <B>1, 2</B> that is or are likely to undergo destructive breakdown by encasing the component or components <B>1, 2</B> in a housing <B>8</B>. If a heat sink assembly <B>6</B> is mounted in contact with a face of the component or components the housing <B>8</B> may be arranged to shield the remaining exposed faces of the component or components <B>1, 2</B> . The housing <B>8</B> may comprise a tray having a base which may be interposed between the component or components <B>1, 2</B> and the printed circuit board <B>3</B>. The housing <B>8</B> may be formed from a folded blank of non-flammable material. The housing <B>8</B> may also comprise a lid formation.
