FAQs - Frequently Asked Questions

What is an In-Cicruit Test (ICT)?

The in-circuit test is a test procedure for testing electronic assemblies and populated circuit boards (PCBA). The focus is on testing analogue component parameters (e.g. resistance, capacitance, inductance),
as well as the testing of digital components (ICs) with the help of defined test signals that are fed in and whose effects are measured.

What exactly are Automated Test Equipment (ATE)?

The term "automated test equipment" includes machines and systems that incorporate measurement technology and stimulation in order to test the products manufactured by the electronics industry. Depending on the design of such test systems, for example
integrated circuits, analogue components or even complete printed circuit board assembly (PCBA) can be tested. Often, contact tests, parameter tests or function tests are carried out separately - but some systems also combine these tests.

What is a PCBA?

PCBA stands for Printed Circuit Board Assembly.

What is a parametric test?

A parametric test measures analogue component parameters such as resistance, capacitance, forward voltage, leakage current, supply voltages.

What is a functional test (FCT)?

A functional test checks the entire function of a module (communication, behaviour, reaction to stimulation) or a building block (logical operations, write/read).

What is a bed of nails fixtures?

A bed of nails fixtures is used to test electronic assemblies - the fixture contacts circuit boards or components using fine test needles to stimulate or measure signals.

What does MSA 1 mean?

MSA 1 is the abbreviation for Measuring System Analysis or Measuring Equipment Capability Analysis or Test Equipment Capability Analysis in Procedure 1. This procedure examines the accuracy and repeatability of a measuring system.

What does MSA 2 mean?

MSA 2 is the abbreviation for Measuring System Analysis or Gauge Capability Analysis or Gauge Capability Analysis in Procedure 2. This procedure examines the repeatability and reproducibility of a measuring device.

What does traceability mean?

Traceability means that a product can be traced back to when and where it was manufactured, tested, stored, transported and sold.

What is True Parallel Testing?

True Parallel Testing stands for a technology that enables the true parallel (i.e. simultaneous) testing of several assemblies.
