In a step for laminating a stack of layers (21, 22) together in the manufacture of a low-temperature co-fired hybrid circuit having a recess, an insert (23) is disposed in the recess and a resilient pressure pad (24) disposed over the insert and stack. This serves to improve lamination and prevents bowing of the sides and base of the recess. The insert may be of metal and separate from the pressure pad or of resilient material and integral with the pressure pad (3 - Figure 2; 33 - Figure 12). |
