Test Fixtures FAQs
How much does a test fixture cost?
The cost of a ICT Fixture or Bed Of Nails Test Fixture varies depending on PCB complexity, test-point count, and custom features, with Forwessun providing tailored quotations for each project.
As a guide:
Simple bed of nails PCB test fixtures for boards with a lower test-point count are generally more cost-effective.
High-density, complex fixtures with thousands of nodes, dual-well functionality, or specialised mechanical features will require greater design and build time, and therefore come at a higher cost.
Who manufactures test fixtures?
Forwessun is a specialist ICT test fixture manufacturer with over 50 years of experience in automated test equipment. We design and build custom in-circuit test fixtures for HP 3070, Teradyne, GenRad and other major platforms, serving electronics manufacturers across automotive, medical, aerospace, telecoms and industrial sectors worldwide. Our production facilities are based in the UK, with global field support available.
Do you have test fixture case studies?
Yes. Our case studies cover a range of industries and fixture types, including in-circuit test fixtures for complex high-density boards and full turnkey projects from DFT through to commissioning. The case study on this page covers our HP 3070 fixture work for a leading UK manufacturer. You can view further examples and project images in our Test Fixture Project Gallery and Case Studies pages.
What is a bed of nails fixture?
A bed of nails fixture, also known as a Test fixture, is a type of PCB test fixture that uses spring-loaded pins (“nails”) to make electrical contact with test points on a board. They are used in both ICT and Functional Testing.
What is a Test Fixture?
For people not familiar a common question is usually what does a test fixture do? A test fixture is a device commonly used in the industry to test electronic components like PCB's or PCBA's by providing a consistent and controlled environment. In electronics, test fixtures ensure that devices under test (DUT) are properly positioned and connected for accurate testing.
Are Forwessun Fixtures Customisable?
Yes, fixtures can be customised based on the client's requirements. In-Circuit Test Fixtures are available in both inline and standard setups. We can incorporate various custom features, such as wireless functionality, vortex cooling mechanisms, and automatic opening and closing capabilities, among others.
How does Forwessun ensure the quality of its test fixtures?
Forwessun leverages over 50 years of experience in providing test fixtures, software, and systems. The company employs advanced manufacturing facilities and experienced test programming teams to deliver high-quality, reliable, and cost-effective solutions tailored to customer needs.
Do you have more examples of test fixture projects I can see?
Yes, you can view our Test Fixture Project Gallery to see more detailed and close-up images of our custom fixture solutions.
How do you design ICT Test Fixtures
When you work with Forwessun we will follow a precise fixture design process. First of all, we will work with you and our engineers and our design team to help create a plan for the perfect bed of nails fixture design that meets your needs. You will be updated and guided through every part of the design process up to completion. You can learn more about the ICT Design for Test process here.
Why is testing important?
The testing process is critical for Testing PCBs. Fixtures provide detailed information about defects found within the PCB early on in the manufacturing process. If PCBs are not tested, it could result in faulty products going to market.
Do you provide fixtures globally?
We provide test jigs all over the world. Our experience and wide range of support options make us one of the leading global suppliers, supporting various industries across the globe, including companies in Europe, Asia, The United States of America and Canada with Test Equipment.
What is a Pogo Pin?
A pogo pin is a common name for the spring‑loaded test probes used in bed‑of‑nails PCB test fixtures.
Each pin contains an internal spring that allows the probe to compress and maintain consistent, reliable contact with the PCB’s test pads during ICT or FCT testing.
