Part 4. DFM & Assembly Specifications (The Process)

A perfect schematic means nothing if the board cannot be manufactured at scale. This section bridges the critical gap between digital CAD design and the physics of soldering.

It covers the essential translation layers:

• Geometric Precision: Defining precise land patterns, component spacing, and polarity to prevent defects like bridging and tombstoning.
• Process Chemistry: Specifying the correct alloys, stencils, and flux to match the thermal profile and component requirements.

This ensures the design is not just functional, but manufacturable.
