Which statement best differentiates Micro-miniature repair from Miniature repair?

• A. Miniature repair involves soldering and repair of CCA's, applying coating, installing wires and connections.
• B. Micro-miniature repair involves welding large power components.
• C. Micro-miniature repair uses multiple layer, flexible CCA's with smaller wires and more complex.
• D. Miniature repair uses multi-layer CCA's.

Answer: (C)

Micro-miniature repair is defined by working with highly dense, multi-layer, flexible circuit card assemblies that use very fine wires. This brings greater complexity and tighter tolerances, so technicians must handle thin substrates, micro-soldering, and intricate interconnects. Miniature repair, in contrast, deals with simpler CCAs—larger wires, fewer layers, and less density. That difference in scale and interconnect complexity is what sets micro-miniature apart. So, the key point is that micro-miniature repair uses multi-layer, flexible CCAs with smaller wires and more complex interconnections. The other statements don’t fit because they either describe aspects not unique to micro-miniature (like general soldering tasks) or incorrectly assign multi-layer CCA usage to miniature work, or suggest welding large power components, which isn’t characteristic of micro-miniature.
