Methods of printed circuit board testing


This course provides attendees with a basic knowledge of unloaded printed circuit board (PCB) testing methods and touches several advanced topics. The course starts with description of basic testing methods, reviews current solutions, their limitations and current challenges. All main types of test systems – optical, “bed of nails”, “flying probe” with their testing methods and fields of application are reviewed through the course. The course proceeds with advanced topics – test splitting, high voltage and Kelvin measurements, latency test and test of embedded components. Finally new ideas: accelerators, e-beam and photo-current testers, etc. are discussed. For all test methods their physical principles, merits and limitations are detailed. 

Learning outcomes 

This course will enable you to: 
  • Apply testing methods correctly and with confidence 
  • Describe physical principles, merits and limitations of test methods 
  • Identify the best test system for your specific task 
  • Avoid common mistakes and misconceptions related to specific methods 
  • Justify use of several test methods to build flexible and trustful testing solution 

Intended audience 

This material is intended for technicians and engineers who want to learn the basics of unloaded PCB testing for their everyday work. Those who want to implement or to improve certain test solutions will find this course valuable.
