The Importance of In-Circuit Testing (ICT) in PCBAs

PCBAs are intricate assemblies with numerous components and solder connections. To ensure their flawless performance, In-Circuit Testing (ICT) is vital. ICT assesses individual components and electronic characteristics for imperfections. It’s a longstanding, dependable testing method in electronics.

PCBA ICT Testing

ICT, or In-Circuit Testing, detects defective components using electrical probes to check specific points on the board. It examines shorts, opens, resistance, capacitance, and more. This automated process allows for immediate repair or replacement of faulty parts.

Advantages of PCBA ICT Testing

  • Detects manufacturing defects such as component spacing, soldering, shorts, and more.
  • Easy to program using PCB layout files.
  • Results are straightforward to interpret.
  • Disadvantages of ICT Testing

Requires expensive test fixtures.

May struggle with connector faults in small components.
Results vary if test pins don’t make proper contact.
Regular pin maintenance is essential.
Despite its drawbacks, ICT remains one of the best PCBA testing methods. It’s efficient, and our experienced team at Auspi can assist you with your project.
