High-Precision SMT PCB Assembly: Placement, Soldering & Quality Control

Witness solder paste printing, component placement, reflow soldering & smart inspection; see how electronics are made

Classification of Key PCB Assembly Processes and Their Suitable Scenarios

Three core PCB assembly processes precisely meet diverse needs: SMT enables high-density mounting, empowering miniaturization of consumer electronics and medical devices; DIP enhances mechanical stability, suitable for industrial control and security equipment requiring durability; BGA optimizes heat dissipation and signal transmission, supporting high-end communications and high-performance computing products. Full-scenario process coverage creates reliable electronic cores.

Key Aspects of Material Management and Selection in PCB Assembly

  • PCB Assembly Services

    Core Materials:

    Solder Paste (selection between lead-free and leaded types, matching melting points)FluxComponents (verification of original vs. substitute parts)
  • PCB Assembly Services

    Material Control:

    Component Storage :Electrostatic discharge (ESD) protectionTemperature and humidity control (≤60% RH) Part Number Traceability :Batch managementBarcode binding to ensure full traceability

Quality Control System for the Entire PCB Assembly Process

  • PCB Assembly

    In-Process Inspection

    In-Process Inspection :Online Inspection :AOI (Automated Optical Inspection) for placement deviation and solder joint voidingSPI (Solder Paste Inspection) for printing thickness and area Offline Inspection :X-Ray inspection for BGA bottom solder jointsICT (In-Circuit Test) for continuity and short-circuit verification

  • PCB Assembly

    Final Inspection Criteria

    Final Inspection Criteria :Electrical Performance :Functional integrityVoltage withstand and insulation testingAging tests Appearance Standards :Compliance with IPC-A-610 specifications (solder joint fullness, component misalignment ≤0.3mm)

  • PCB Assembly

    Exception Handling

    Exception Handling : Rework Process (hot air desoldering, component replacement)Defect analysis and traceability
