✅ 8.1. Component Placement Standards
Objective:
Ensure that components are correctly placed on the PCB for optimal performance and functionality.
Key Requirements:
-
Component Positioning: Components should be placed within the specified tolerances (often ±0.1mm or better) to prevent issues during soldering or mechanical interference.
-
Orientation: Polarity-sensitive components (e.g., diodes, capacitors, and ICs) must be placed in the correct orientation as indicated by the design.
-
Clearance: Sufficient clearance between components to allow for proper heat dissipation, avoid electrical shorts, and ensure there is no mechanical interference.
-
Placement Accuracy: Fine-pitch components (e.g., BGAs) require precise placement and should be aligned to within the tolerances specified by the manufacturer.
-
Component Type Compliance: Ensure that only authorized components, as specified in the design (BOM), are used for assembly.
Standards:
-
IPC-2221: Generic requirements for designing printed boards and other forms of component mounting or interconnecting structures.
-
IPC-2581: A standard for the design and manufacturing of printed circuit boards.
-
J-STD-001: Requirements for soldered electrical and electronic assemblies, including component placement.
