In-Circuit Test Fixtures (ICT) for Thorough and Reliable PCB Testing

Microhub produces and delivers precise in-circuit test fixture for today’s electronic assembly lines. Our software solution lets you check every component on the populated PCB to see if they are working properly and meet quality guidelines.

An ICT Test Fixture is important for detecting shorts, opens, wrong component values and soldering mistakes during the production of products. With accurate contact to a large number of test points on a PCB, these fixtures make it possible for technicians to use fast and non-invasive quality control testing.

Microhub’s custom ICT fixture is reliable for both high-volume assembly and the validation of prototypes in today’s advanced electronics industry. We provide ICT fixture for different brands like Keysight, Agilent, Brands we provide ICT fixture Teradyne, Test ResearchInc. (TRI), Keysight, Agilent

Key Features

Custom Test Coverage

Fixtures are tailored to match your specific PCB layout, ensuring access to all necessary test points for component-level diagnostics.

Rugged and Reliable Build

Constructed from industrial-grade materials like stainless steel and aluminum for long-lasting, repeatable performance

High Pin Precision

Guided probes connected with springs allow BGAs to make precise and stable contact with tiny pads.

Efficient Operator Handling

Decisions to optimize loading and unloading, as well as transitions, reducing strain and boosting speed.

Flexible Design Options

Can be used in manual or automated testing setups, with choices for full-bed-of-nails, hybrid or specific target testing.

Comprehensive Electronic ICT Testing

comprehensive Electronic ICT testing, the board is tested with analogue, digital and mixed-signal approaches for a complete verification.

How It Works

Fixture Setup

Adjust the probe and guide pins equally with the corresponding probes in the test layout.

Board Placement

Place the PCB in the fixture, lining it up with the mechanical tools so there is perfect contact with all the test probes.

Probe Engagement

Place the fixture lid down or engage the clamping mechanism to make sure all test probes touch the pads on the board.

Testing and Analysis

Tests are performed entirely by automation or by hand to check the short, open and component-level parameters of the equipment. Performances are reviewed to rate board effectiveness.

Applications

  • PCB In-Circuit Testing for Mass Production
  • Component Integrity Verification
  • Electronic ICT Testing in Quality Control
  • Development and Engineering Test Stations
  • Custom ICT Fixture Solutions for Complex Boards

Technologies Used

Precision Probe Technology

Many test probes attached to a spring-loaded gadget are used at the same time for contact with pads, traces and leads.

High-Tolerance Mechanical Design

The parts and alignment features made by CNC machining ensure fixtures fit and contact perfectly.

Signal Isolation and Grounding

Proper grounding and probe design can cut down on signal interference and raise the precision of measurements.

Ergonomic and Modular Setup

Modular handles and levers allow you to complete testing more quickly, altering the board frequently if needed.

FAQs

In-Circuit Test Fixtures from Microhub can be used with single-layer, multilayer, rigid and flexible types of PCBs. Because each fixture is made to fit your board precisely, all test points can be reached by probes accurately. For all types of designs, our solutions make it possible to verify each component at the IC level.
Using ICT Fixtures, multiple connections along a board can be checked at once, decreasing the test cycle time. As a result, landing the probe takes less time, everything aligns automatically and defects can be detected easily. It makes less reworking required, increases production quality and speeds up testing, mainly in busy settings.
Yes. Microhub is skilled at creating Custom ICT Fixtures that work well in situations with many connections, congested routing and large numbers of pins. PCB design data from you help our engineers design accurate probe maps and fixture layouts. We help you by testing fully and making sure our tests integrate with your existing systems, no matter if they come from third parties.
We make all necessary parts of the machine using anodized aluminum, stainless steel and Delrin to ensure they are both sturdy and precise. They allow for correct performance and durability each time the machines are used. When used with excellent probes and equipment, our materials allow your test fixture to stay stable, accurate and reliable throughout thousands of tests.

All fixtures are subjected to detailed evaluations, checking their dimensions, mechanical behavior and electrical links. We simulate the way each unit will be used, to check for both durability and proper functioning.

We generates test fixture test report in which fixture needs to undergo with 30 + Test parameters to ensure fixture works as per our client requirements. The thoughts and opinions of our users are included when we look to improve the service. We aim to provide Test Fixtures that are strong, precise and set up so they can immediately be used by professionals.

Prior to shipping, every ICT Test Fixture is tested to ensure it is accurate mechanically, has the right probe force and is electrically sound. The team always tests and aligns fixtures to confirm they satisfy your test requirements. Our support and optimization after your products are in use help ensure they maintain accuracy and you keep seeing good results from ICT testing.
