The compact circuit package (11) includes an insulating housing (12) providing a circuit retaining cavity (19) substantially surrounded by a pair of spaced side walls (15, 16) each terminating at a first rim (21, 22) and a second pair of spaced side walls (17, 18) each terminating at a second rim (24, 25). Each of the side walls provides an abutment (28, 31, 34) which limits the depth of entry of an electrically insulating, heat conducting substrate (30) into the cavity (19). Outer portions (44, 45) of a first pair of side wall rims (21, 22) are removed such as by a sander (46) to form a clamping surface (48) which includes an outer surface (42) of substrate (30) and reduced end portions (49, 50) of the pair of the side wall rims (21, 22) to permit increased substantial clamping pressures to a substantially planar external heat dissipating object (51) without damaging the substrate (30) and the side walls (15, 16, 17, 18).
