(13) Inner layerICT test fixtures are primarily used for testing assembled circuit boards (PCBAs). Online testing specifically refers to the testing of electronic circuit boards.
ICT test fixtures are primarily used for testing printed circuit board assemblies (PCBAs). "On-line" refers specifically to electronic components that are located directly on the circuit board or in the circuit itself. On-line testing is a testing technique that does not require disconnecting the circuit or removing component leads. The term "on-line" underscores ICT's focus on detecting PCB assembly issues by testing the status of components—such as open circuits or short circuits—directly on the circuit board. The primary tests performed include checking for open and short circuits, as well as measuring resistance, capacitance, inductance, diodes, transistors, ICs, and other components. ICT testers are widely used in electronics manufacturing plants. So, what are the advantages of these test fixtures? What functions do they perform, and what are the underlying principles behind these functions? Let’s take a closer look at the specific analysis below.
Advantages of test fixturesThe test fixture can accurately pinpoint product quality issues. For the manufacturing process, it can detect faults such as solder shorts, component misinsertion, reverse insertion, missing components, bent pins, cold solder joints, PCB shorts, and open circuits. The test directly locates faults to specific components, device pins, and network nodes, ensuring highly accurate fault identification. Repairing these faults does not require extensive specialized knowledge, and the test is automated with program-controlled operations, making it simple to use and quick to perform. Typically, the testing time for a single board ranges from a few seconds to tens of seconds. The system can directly process Gerber files to generate drill files, guaranteeing drilling accuracy. The test programs are automatically generated, eliminating the possibility of manual input errors.
General Functions of ICT Test Jigs
All components on the circuit board—resistors, capacitors, inductors, transistors, FETs, and LEDs—will be inspected.
ICT can operate ordinary diodes, Zener diodes, optocouplers, ICs, and other components in just a few seconds, regardless of whether they are operating within their design specifications. Feedback on process improvements.
ICT can detect defects in the manufacturing process at an early stage, such as short circuits, open circuits, missing parts, reversed polarity, incorrect parts, and false soldering. It also includes fault localization, part specification values, and test results.
ICT can print the aforementioned faults or undesirable information onto a printer, generating test results for reference by maintenance personnel. This effectively reduces the reliance of personnel on product-specific technical expertise; even without in-depth knowledge of the product line, they can still perform maintenance tasks.
Principle of ICT Test Jigs
The manufacturing principle of ICT test fixtures: Based on the mechanical dimension drawing of the circuit board, punch holes for DIP pins and test points on the board, then insert the pins. The nets on the circuit board represent the PCB wiring; all nets are routed externally, allowing instruments to test the internal circuit structure.
The working principle of an ICT test fixture: It primarily relies on test probes contacting the test points on the PCB to detect the PCB’s circuitry. Typically, the ICT test fixture is the first testing step in the production process, enabling timely feedback on the production status and facilitating process improvements and enhancements. Due to its specificity in testing items, it has become one of the crucial testing methods for quality assurance in modern mass production.
