Product Overview: 

The UK-made ABI-3400 circuit board fault detector can analyze components and perform full-board testing under static (non-powered) conditions. Utilizing a unique three-dimensional V-I-F dynamic impedance testing method, it measures electrical signal curves, detects errors/flaws, including internally damaged components and inconsistent components, expanding the scope of problem detection while reducing testing time!

Product Composition:

1. Software Configuration:

1) Features test process memory function (the software has powerful test process editing and recording capabilities).

2) *Comprehensively records various test information. The software can store V-I-F, V-I, and V-T curves measured on standard circuit boards into test programs, facilitating comparisons with other circuit boards at any time, greatly simplifying repetitive comparison tasks during testing.

3) The software allows users to add text descriptions, photos, Office Word, Office Excel, PDF documents, web links, etc., to test steps as needed, significantly improving testing efficiency.

4) *Chinese and English test operation software, providing free lifetime software upgrade services.

2. Hardware Configuration:

1) Features 64-channel digital V-I dynamic impedance testing (expandable to 2048 channels).

2) *Features 64 V-I-F and V-I test channels, 4 probe test channels, and 4 sets of synchronous pulses. Equipped with variable-frequency three-dimensional V-I-F measurement mode, it three-dimensionally displays the port characteristic curves of components. Can detect faults related to component frequency. Three-dimensional and two-dimensional views can be switched, and electrical parameter values (V/I) of each point on the curve can be displayed on the two-dimensional graph: specific voltage and current values. Expandable to 2048 V-I-F test channels.

3) *The system can perform port tests on various components: V-I, V-T, V-I-F, V-T-F testing. Two-dimensional V-I testing frequency as low as 1Hz, testing frequency up to 10kHz, very suitable for testing inductors and high-frequency capacitors. Can set the amplitude and width of synchronous pulse signals for functional testing of thyristor components or FETs.

Features:

Static diagnosis of circuit boards, testing can be performed without external power supply. Detects damaged components on circuit boards. Can detect components with leakage-type faults. Can detect inconsistent components. Minimizes the risk of damage. Features multi-channel testing (64 channels), reducing testing time. Channels expandable to 2048.

What is V/I Curve Testing?

For analog and digital circuit boards, V/I curve testing is a mature and reliable solution. By applying an AC voltage to a test point through a current-limiting resistor, the resulting current is measured, and the results are plotted as a voltage/current graph, displaying the characteristic curve of that test point.

Analyzing V/I curves, typically by comparing them with a reference point, detects issues such as: Leakage current components. Internally damaged components. Components with incorrect values. Inconsistent components. Short circuits and open circuits.

Variable Frequency Scanning Method---Expands Problem Detection Range!

The UK-made ABI-3400 circuit board fault detector increases problem detection range by changing the frequency of the AC voltage of the V/I signal. The resulting curves are plotted in a 3D window, allowing users to observe V/I curve changes across the entire frequency range, thereby identifying issues not visible with standard V/I analysis methods.

Matrix Scanning V/I-----Expands Problem Detection Range!

The ABI-3400 module can also use matrix scanning to obtain V/I curves, expanding the problem detection range. In this mode, the ABI-3400 module obtains V/I curves for each pin of a component or circuit board by referencing all other active pins (unlike standard V/I testing which uses only one reference pin). This generates a rich dataset (400 curves for a 20-pin component), sufficient to detect hard-to-find faults.
