2018年12月12日 · ICT最主要用于 电路组装板 (PCBA，Printed Circuit Board Assembly)的电性测试，基本上可以将其想像成一台高级的「万用电表」或是【LCR meter】，它无需将电子零件从电路板上拆下来就可以透过针点来检测电路板上所有零件的电性以及焊接有没有开/短路问题。 ICT的作业原理是使用针床 (Bed of Nails)连结电路板上事先布置好的测试点 (Test Point)来达到单独零件或是Nets测试的目的。

In-Circuit Test (ICT) is a widely used and cost-efficient [3] method for testing medium- to high-volume electronic printed circuit board assemblies (PCBAs). It has maintained its popularity over the years due to its ability to diagnose component-level faults and its operational speed.

Pin card : 提供测试时的复用系统，每块双密度的Pin card提供用于测试的针数144。一个Module的测试能力为144*9=1296点。

2022年12月21日 · ICT (in circuit test) is mainly used for electrical testing of PCBA (printed circuit board assembly). Basically, ICT can be imagined as an advanced multimeter or LCR meter. ICT does not need to remove electronic components from the circuit.

Robust, compact design for harsh ICT/FCT applications with limited space; For optimum contact at the test points (e.g. pads, vias, and pins), various tip styles in different diameters and finishes, as well as various spring forces are available. spring forces.

The ICT/FCT product line, which includes LFRE, POGO Plus, Pylon and long travel probes, addresses the unique demands of loaded board and vacuum fixture applications. ECT developed various features to optimize the probe performance: bias-ball design, proprietary plating processes and the precision MicroSharp tip.

公制弹簧探针（公制标准弹簧探针）是对传统无卡环 ICT / FCT 探针的补充。 此类探针以其高度的稳定性和坚固性而著称，且都具有压制的卡环。 INGUN Socketless Serie 包括 S-Line 探针和 S-Line 接触端点，无需针套即可进行测试。 由于省去了针套，我们的 S-Line 探针在同样的栅格中具有更大的直径，且机械稳定性更佳。 坚固、精确的探针让您能够在小栅格内准确地进行测试，且信号重复精度高。 更多信息. 具有不同直径和表面处理的各种针头形状可供选择，从而能够保证 …

The Keysight Technologies, Inc. i3070 and 3070 are the world’s highest pin count in-circuit test (ICT) systems and bring an unprecedented level of performance and portability to the high node count (HNC) test market.

We offer test plugs for the testing of PCBs (ICT+FT) and cable harnesses, test probes as charging contacts for industrial applications or PCB connectors – here as a single contact or multi-pole contact block.

The ICT (In-Circuit Test) and the FCT (Functional Circuit Test) allow to detect the main faults that can be found in a PCB (Printed Circuit Board), such as short circuit sor an incorrect component, and to measure the values of resistance and capacity.
