Frequently Asked Questions

Common questions about our custom fixture and tooling solutions.

What information do you need to quote a custom fixture?
To provide an accurate quote, we typically need: PCB Gerber files or assembly drawings, test specifications (test points, voltage/current requirements), desired actuation method (manual, pneumatic, vacuum), target volume or expected service life, and any special environmental considerations (temperature, ESD requirements). You can also send us photos of existing fixtures or competitor samples for reference.
What is the typical lead time for a custom fixture?
Standard lead time is 7–14 working days from design confirmation, depending on complexity and material availability. Simple test fixtures can be ready in 5–7 days, while complex pneumatic or automated fixtures may require 15–25 days. Expedited service is available for urgent production needs — please contact our sales team to discuss your timeline.
Can you design fixtures compatible with our existing test equipment?
Yes. Our fixtures are designed to integrate with major ICT and FCT platforms including Agilent/Keysight, Teradyne, TRI, Hioki, and custom-built test systems. Simply provide us with your equipment model or interface specifications, and we will design accordingly. We can also reverse-engineer from existing fixtures you currently use.
How do you ensure fixture quality and accuracy?
Each fixture undergoes a multi-stage quality inspection process: first article inspection of machined components, probe placement verification using coordinate measuring, full functional testing with your PCB (if sample provided), and final acceptance testing before shipment. We use CNC machining centers with ±0.02mm positional accuracy and maintain strict process control throughout production.
What is the typical lifespan of a test fixture?
Fixture lifespan varies significantly based on material, actuation frequency, and maintenance practices. Generally: synthetic stone wave solder pallets last 10,000–15,000 cycles, aluminum test fixtures 8,000+ cycles, FR-4 fixtures 3,000–5,000 cycles, and bakelite/Acrylic jigs 1,000–3,000 cycles. With proper maintenance — including regular probe replacement and cleaning — service life can be extended significantly.
Do you offer fixture modification and repair services?
Absolutely. As your products evolve through revisions, we can modify existing fixtures to accommodate PCB design changes, new test points, or updated specifications. We also offer repair services including probe replacement, pneumatic component servicing, and structural repairs. For customers with ongoing production, we offer maintenance packages to ensure consistent fixture performance.
Can you export fixtures internationally? What about shipping?
Yes, we ship fixtures worldwide. For international customers, we carefully package fixtures in custom foam-lined wooden crates to protect precision components during transit. We support DHL, FedEx, UPS, and sea freight options. Typical international shipping time is 3–7 days by express or 20–35 days by sea. All export documentation and customs support is provided.
What if the fixture does not work as expected upon delivery?
We stand behind our products with a comprehensive quality guarantee. If a fixture has dimensional or functional issues due to our design or manufacturing errors, we will repair or replace it at no additional cost. We also offer remote technical support via video call to help with installation and commissioning. For larger projects, on-site installation and training can be arranged.
