The skeleton and the matrix of the direct sliding potentiometer are usually made of materials with good insulating properties, which require heat resistance, moisture resistance, good electrical insulation, good chemical stability and thermal conductivity, and only a certain mechanical strength. In general, there are laminated paper and rubber board, laminated cloth cover board, plastics, ceramics, glass and metal substrate with insulating treatment such as copper, aluminum and aluminum alloy on the surface. Such metal substrate with insulating treatment on the surface shall have sufficient surface insulation, and such skeleton matrix shall have good heat dissipation and be easy to form.
