Complete ICT Test Solutions – Smart SMT Tools Delivers Both the ICT Tester Machine and the ICT Test Jig

At Smart SMT Tools, we know that quality assurance in electronics manufacturing begins long before final product testing. It starts right on the production line—with in-circuit testing (ICT). As defects become more costly the further they travel downstream, integrating an effective ICT solution becomes a key priority for every SMT manufacturer.

That’s why we provide both ICT tester machines and custom-designed ICT test jigs—ensuring our customers have a complete, reliable, and production-ready test platform.

What Is an ICT Tester?

An ICT Tester is an automated system designed to electrically test individual components and interconnections on a PCB (Printed Circuit Board) after assembly. Unlike functional testers that evaluate the board as a whole, ICT checks each part in isolation to identify exact points of failure.

It typically involves:

• Bed-of-nails fixture or probe test jig
• Automated measurement of resistance, capacitance, diode voltage drop, transistor switching, and more
• Identification of soldering issues, missing components, short circuits, open circuits, polarity errors

Why Use ICT Testing?

At Smart SMT Tools, we see ICT testers as essential in any quality-driven SMT line for several reasons:

✅ Early Detection of Defects

ICT can identify more than 90% of common assembly errors, including:

• Open circuits
• Shorts
• Wrong component values
• Misoriented components
• Soldering issues

✅ Fast, Repeatable, and Scalable

Once programmed, ICT offers automated testing in seconds per board, ideal for mass production lines.

✅ Precise Fault Isolation

Unlike functional testing, ICT pinpoints the exact failing component or net, making troubleshooting faster and more cost-efficient.

Smart SMT Tools Provides Two Critical Parts of the ICT Solution

1. ICT Tester Machine

Our ICT tester machines are designed to be compact, user-friendly, and compatible with a wide variety of test jigs and software environments. Key features include:

• Precise electrical measurement capabilities (resistance, capacitance, diode voltage drop, transistor function, etc.)
• Multi-channel testing for high-density boards
• User interface through PC using Arduino IDE, LabVIEW, or dedicated software
• Support for push-button control, LCD status display, buzzer alerts
• Data export functionality to Excel or database
• Optional IOT connectivity using ESP8266 module

Whether used in R&D or for inline production testing, our ICT machines are engineered for stability, repeatability, and flexibility.

2. Custom ICT Test Jigs

Our in-house fixture team designs high-precision test jigs tailored to your PCB layout. These jigs ensure accurate contact with each test point using pogo pins or probe needles.

Key features of our ICT jigs:

• Supports up to 600×400mm panel size
• ±0.01mm hole and outline tolerance
• Robust frame with aluminum or durostone base
• ESD-safe materials and ergonomic design
• Multiple pin interfaces for multi-board panels
• Designed for push-down or vacuum-actuated contact

Our jigs are compatible with most leading ICT platforms, including Agilent, Keysight, Teradyne, and custom bench setups.
