THT Line

Safe Optical Inspection of THT Assemblies and Solder Joints with THT Line

THT Line

THT Line is an AOI System for efficient quality assurance of THT assemblies, THT solder joints and wave soldered SMD components in the production process. An inspection of hidden components and vertical labels is possible with up to 8 angled-view cameras.

A double-sided inspection of THT assemblies can be realized either on the upper transport or lower return. The assemblies can be loaded automatically or manually, with or without carrier. The height-adjustable camera module allows a component clearance of up to 140 mm. 


  • unique multispectral illumination
  • 4 or 8 angled-view cameras
  • THT component, THT solder joint and wave-soldered SMD component inspection
  • freely configurable test functions and illumination opportunities

Speed Advantages over common AOI Systems

  • ”flip free“ double-sided inspection of THT assemblies
  • multiple and independently working AOI modules in one system

3D inspection of THT solder joints

  • determination of solder flow, solder volume and pin height of THT solder joints
  • inspection of the PCBA bottom side, both from above and below
  • cost-effectife system configuration
  • can be integrated into AOI system THT Line, optionally with workpiece carrier return in the lower section of the AOI system
  • inspection of THT assemblies with or without workpiece carriers


  • PILOT AOI - user software
  • reference database
  • program optimization by means of statistically recorded inspection data
  • fully automatic generation and optimization of test programs for THT solder joints with MagicClick

Integration Options for THT Production Process

  • manual or automated feeding
  • component side and solder side can be inspected at multiple positions within the production line
  • solder side inspection either on the upper conveyer belt or during the PCB return in the lower system area

Fully automated generation and optimization of test programs for THT solder joints

MagicClick for THT solder joints

available in software PILOT AOI Version 6 for THT Line

  • generates production-ready test program including component library in only a few minutes
  • PCB-specific layout is considered through import and automatic analysis of Gerber data
  • optimization of inspection parameters based on sample PCB and IPC standard
  • efficient use of AOI already for second PCB
  • up to 80% time savings for test program generation and optimization
  • guarantees return on investment in the shortest time
