Types of testing: the different arrangements

Our engineering team has over 30 years of experience in designing and implementing test systems and tools. We are one of the few contract manufacturing services company to have its electronics design and manufacturing departments in a single location (in Poland), so we can flexibly build test environments. We can create a test environment as defined by our customers or develop a complete test solution at the device, board or component level from scratch.

Thanks to our expertise and flexibility, we support customers in confidently bringing their products to market, knowing they have been thoroughly tested and met all necessary standards. As a trusted partner for lab tests to companies needing high-quality testing solutions, we have built our reputation based on consistent effort, well-established process and a commitment to ethical business practices.

Types of test:

  • Manual and automatic 
  • Functional 
  • Non-functional 
  • Regressive

PCBA unit test

PCBA (Printed Circuit Board Assembly) unit testing is a crucial step in the manufacturing process of electronic devices. It involves testing the individual components on the PCB before they are integrated into the final product. This testing aims to detect any defects in the PCB components, ensure that they function as expected, and prevent any issues that may arise from faulty parts.

These tests can be automated or manual, depending on the components' complexity and the level of precision required. Regardless of the type of testing used, PCBA unit testing is essential for ensuring the quality and reliability of electronic devices. Defective components can lead to product failures, safety hazards, and costly recalls, so detecting and replacing faulty components as early as possible in the manufacturing process is crucial.

PCBA unit testing can also involve visual inspection of the PCB components to ensure they are properly aligned and free of defects. This can include using specialized equipment, such as microscopes and X-ray machines, to inspect the components at a microscopic level.

Manufacturing PCBA tests:

  • Mechanical functional tests
  • Function test (FCT)
  • ICT testing - on the roadmap
  • Functional/built-in tests
  • Visual inspection (AOI)
  • JTAG boundary scan

Box build unit test

Box build unit tests are a type of testing that verifies the functionality of the final product or sub-assemblies at the system level. Box-build unit tests in electronics manufacturing aim to ensure that the system or product operates as expected and meets the required specifications. These tests may involve checking various aspects of the development, such as its electrical functionality, physical durability, and environmental resistance.

Engineering and Design Verification of the product:

  • Firmware and software functionality tests
  • HW performance Regulatory compliance tests (e.g. EMC and radio tests)
  • Design for Manufacturing and Assembly (DFMA) verification
  • Design for Testability verification 


Environmental stress tests:

  • Temperature and humidity (enviromental chambers)
  • Reliability (mechanical stress, lifetime simulation)
  • HALT tests 

Integration tests

Integration testing involves verifying the performance of the system or subsystem as a whole, including interactions between individual components and modules. The goal of integration testing is to identify any defects or issues that may arise when components or modules are combined and to ensure that the system functions as expected under normal and abnormal conditions.

In addition, integration testing may be performed using different levels of integration, such as system-level or module-level integration, depending on the complexity and scope of the system being tested.

Bring-up tests

  • Testing power, clocks
  • Basic connectivity and functionality 


Electrical

  • Power supplier test
  • Voltage and current test and verification
  • Power factor and efficiency measurement
  • Electrical safety tests 

System tests

This type of testing is typically performed after individual components have been assembled and integrated into a complete system and after integration testing has been completed.

The purpose of system testing in electronics manufacturing is to ensure that the electronic system meets its functional and non-functional requirements, including performance, reliability, safety, and regulatory compliance.

RF and optical performance tests:

  • nonlinear RF distortion using spectrum analyzer
  • s-parameters measurements
  • Optical Spectrum tests using OSA
