Hardware and software electronic testing, as well as ergonomic testing are inherent stages of the production process of a new device. Reliable performance and ease of use depend on the completeness and quality of testing. These characteristics are important in consumer mass production, especially for complex consumer electronics.

Production testing allows us to detect defects in the device’s hardware or software and to ensure its expected level of quality.

Promwad experts are ready to provide functionality control and assembly testing at the production site by performing the following tasks:

  • Design and manufacture of testing benches for installation of firmware and testing using JTAG/ICT testing
  • Development of testing systems and quality control criteria for production acceptance
  • Automated or manual testing processes

Types of electronics conducted at the production site:

Visual automated control (AXI / AOI) is a popular technique for preliminary quality control using optical systems and X-rays (for hidden spots), which can be applied at different stages of PCB mounting.

In-circuit testing (ICT / FICT) helps check the components and their connections on the printed circuit board through the use of contact probes, including a stationary field (“bed of nails”) or “flying” probes and matrices. ICT testing is used to analyze electrical parameters of individual sections or the entire circuit. This technique is based on preprocess preparation, manufacturing of tooling, and application of advanced equipment.

Peripheral and boundary scan uses JTAG technologies. This scan can be used for chips with IEEE 1149 support.

Functional testing (FCT) helps check fully or partially assembled devices for correct execution of certain functions defined in the specification.

 

You can minimize risk by using our knowledge and experience. After test evaluation, our clients receive a tested device or electronic module, sets of functionality tests to be used in production, ready-to-use testing programs, and detailed reports.
