A satellite card having a polymer-on aluminum (POA) substrate is mounted on a main electronic card by soldering contact lands of the satellite card to contact lands on the main card to provide both low- cost, low-resistance electrical connectors and a mechanical connection between the two cards. A satellite card 1 (Fig. 1) has an aluminum substrate 2 (Fig. 2) with a layer 3 of polyamide secured to the aluminum substrate 2 by an adhesive 4. The polyamide layer 3 has a copper circuit layer 5 attached thereto by an adhesive 6. The copper circuit layer 5 is etched to have contact lands 7 (Fig. 1) connected to a component 8 mounted on a portion of the copper circuit layer 5 (Fig. 2). Prior to mounting the component 8 (Fig. 1), the satellite card 1 is formed with mounting feet 9 and 10.
