This thick-film hybrid circuit module is part of an anti-lock brake system. It was designed to mount directly on the brake master cylinder where it had to withstand extreme environmental conditions. The module was successfully qualified after being subjected to vibration, brake fluid exposure.

ITT Automotive has applied the modularity concept in designing the antilock braking system (ABS) module (Pisano 1994). Components such as pump, valve block, and motor together form a module-option for the ABS Fig. 3.3 shows four such options (Mi to M4). The ABS options Mj are created by choosing from an assortment of each of these components. For example, the ABS M2 includes the pump pi, valve V2, and motor t2 M2 = ipiAidi)- Each option fitted to the end product creates a product variant. For example different car models can be fitted with different ABS configurations, and so can trucks and SUVs. In Fig. 3.3, two car variants are shown with ABS options Mi and M3, and the two truck variants have ABS options M2 and M4.
