A electronic circuit board arrangement includes a main circuit board on which components are mounted, with component leads passing through holes in this board. Additional components are provided on an auxiliary circuit board at least part of which is directly against the main board, underlying components on the component side of the main board. The additional components are connected to the component leads via conductive tracks on the auxiliary board. The auxiliary board can be flexible to also extend over components on the main board. The arrangement is particularly useful for adding additional components to an original circuit design.
