Delivering Test Automation Across Industries
Holistic Test Systems designs, develops and manufactures customized fully automated and semi-automated test equipment to support engineering product development and production testing. Our products are used in the military, aerospace/avionic, maritime and medical business sectors. By streamlining our product development processes, we have significantly reduced our product development cycle time while ensuring high product quality and reliability.
In-Circuit Testers
Our ICT are designed to evaluate and verify individual components on a printed circuit board assembly (PCBA). Their aim is to detect defects or malfunctions at the component level before they can escalate to system-level failures. Our In-circuit testing provides electronic manufacturers a reliable, high fault coverage verification method for the assembly process. HTS provides ICT fixtures that are robust, reliable and designed for easy customization to cover a large range of PCB sizes without impacting turnaround time.
Our ICT can perform the following:
- Shorts & Opens: the integrity of electrical connections, including solder joints and traces on the printed circuit board (PCB), is checked to identify issues like open circuits, short circuits, or incorrect connections.
- Electronic component test - Resistors, Capacitors, Inductors, Diodes, Transistors, Integrated Circuits (ICs), LEDs, Connectors, Switches and Relays, Fuses, Oscillators and Crystals, Transformers.
- Voltage Levels: voltage levels are measured at various points in the circuit to ensure they meet the specifications.
- Digital Signals: digital signals, such as logic levels (high and low), are checked to ensure that digital components work correctly.
- Analog Signals: components, like sensors or amplifiers, are tested for accuracy and precision in handling analog signals.
- Clock Signals: for timing-dependent circuits, checking the clock signals to ensure they have the correct frequency and stability.
- Boundary Scan Testing: can be used to test the placement of ICs that support the IEEE 1149.1 (JTAG) standard.
- Programming and Configuration: device programming during an in-circuit test involves configuring microcontrollers, PLDs, and other programmable devices with the necessary firmware or parameters to ensure they function correctly as part of the PCB assembly.
- Custom Test Procedures: may be developed to address unique testing needs.
Assemby/ Sub-system Level Testing
Subsystem testing is a type of testing that involves testing a specific component or part of a larger system.. Subsystem testing can be performed in the operational environment using the system's installed hardware and software. It's often done before system testing, which involves testing all the key elements of a system together.
Subsystem testing can have several benefits, including:
- Focusing on a limited set of requirements: Test procedures and personnel can focus on a smaller set of requirements, which can help resolve problems independently of other testing.
- Shorter testing time: Subsystem testing can be completed in a shorter amount of time
- Incremental acceptance: Acceptance can be achieved in stages
System Level Testing
Fully automated or semi-automated system level functional testers. Our testers will perform full functional tests, acceptance tests and qualification tests to validate that all you system requirements have been satisfied. Our systems testers are scalable, capable of handling rapid changes to workloads and user demands.
