Wireless In Circuit Test Fixtures
We also have vast experience in designing Wireless In-Circuit Test (ICT) Fixtures. Our fixtures are tailored to the unique needs of our customers to further enhance all aspects of the test process. Our commitment to excellence and focus on quality and reliability sets us apart in the industry. With a rich history spanning over 50 years, Forwessun continues to deliver cutting-edge software and fixture solutions for leading In-Circuit test platforms.

Functional Test Fixtures
Forwessun specialises in designing and manufacturing custom functional test fixtures to ensure your printed circuit boards (PCBs) operate as intended. Our functional testing process applies full operational power to the PCB assembly (PCBA), enabling thorough verification under real-world conditions. This testing is critical for identifying system-level failures and operational faults that may not be detected during in-circuit testing.
We provide fully customised fixtures tailored to your unique requirements, ensuring precise testing of every component’s functionality on the PCB. Whether you require fixtures built using the Ingun kit or a fully bespoke solution developed in-house, we have the expertise to deliver. With extensive experience in both hardware and software integration, we create comprehensive, fully integrated systems that seamlessly align with your production line.

Wireless Test Fixtures
Wireless In-Circuit Test Fixtures at ForwessunAt Forwessun, we bring extensive expertise in designing and delivering wireless in-circuit test (ICT) fixtures tailored to the unique needs of various industries. While our primary focus has been on developing full and half-bank fixtures for the HP3070 system, we also provide bespoke solutions for other platforms, including GenRad, Teradyne, and SPEA systems.
Our commitment to innovation drives us to continuously improve our processes. For instance, we have successfully automated the generation of probe maps for our interface PCB CAD and developed routing priority instructions to enhance efficiency. Looking ahead, we are working on advanced features such as:
Detecting potential issues with ICT designs and providing actionable solutions.
Identifying and resolving interface PCB design challenges.
Recommending methods to improve signal fidelity, such as isolating RCVA signals.
With a focus on precision, reliability, and cutting-edge technology, Forwessun is your trusted partner for wireless ICT fixtures that meet the highest industry standards.

Platforms
With over 20 ICT program engineers worldwide, Forwessun has test programming teams with unparalleled experience providing test software for the Agilent / Keysight 3070, GenRad / Teradyne TS12x / 228x and Teradyne 18xx ICT test platforms. Many of our programmers have over 25 years programming experience, delivering test packages on various platforms for many customers in different product areas. We will ensure your requirements are met, that the test coverage is as high as possible and that the software is stable and consistent. Many ICT solutions employ device programming and BIST / functional tests to ensure the maximum test coverage.
Functional Software
Experienced in Labview and PLC programming, Forwessun test programmers provide the highest quality functional test, from simple test bench solutions to fully automated inline functional solutions.

Design For Test (DFT)
ICT checks each component on a PCB individually, delivering highly reliable results. It detects defects such as faulty, wrong or missing components, solder bridges and short circuits. While investing in this solution requires a larger initial upfront cost when compared to flying probe, the cost per unit is negligible (often less than £1) due to the swift test time (usually less than one minute).
The ICT method comprises a test fixture and program dedicated to the target test platform and unit under test (UUT). In order to optimise the effectiveness of the test, the circuit design and layout of the PCBA itself must be suitable for ICT. Therefore, design for test (DFT) is an integral stage of PCB realisation; without taking this phase into account, you will not be able to get the most from your test strategy.
Investing in an ICT solution can help your business to consistently deliver fully functional PCBs, on time and to specification. The time and money saved can be redirected back into other core aspects of your operation.

Device Programming
Our programmers are experienced with programming devices using test vectors and also programmers fitted inside the test fixtures to include STLINK, MPLAB, PEmicro Cyclone, FlashRunner, Segger etc. We can generate test vectors allowing us to program / verify SPI flash in Dual and Quad mode.
Test fixture hardware will be used to isolate the programming signals from tester interference, to ensure that the programming is as stable as possible and give you the fastest programming speed.
