Flying needle inspection machineThe flying needle tester and multimeter play different roles in the field of electronic testing, and the main differences between the two are as follows:

1、 Definition and purpose

Flying needle inspection machine:

It is a high-precision circuit board testing device.

It is mainly used to test the electrical connections and component values on circuit boards. By moving probes to touch the solder pads, vias, or component pins on the circuit board point by point, it can determine whether the circuit is unobstructed, whether there is a short circuit or open circuit, and whether the component function is normal.

A multimeter:

It is a basic electronic measurement tool.

It is mainly used to measure electrical parameters such as voltage, current, resistance, etc. in circuits, and can also measure transistors, diodes, temperature, etc.

2、 Working principle

Flying needle inspection machine:

Equipped with multiple sets of high-precision robotic arms and extendable testing probes.

Control the probe through a computer to perform point by point testing according to a preset path and sequence.

A multimeter:

Based on a sensitive magneto electric DC ammeter (meter head) as the measurement basis.

Measure the current, voltage, and resistance in a circuit by diverting or reducing voltage through parallel or series resistors. A digital multimeter converts analog signals into digital signals for display.

3、 Testing accuracy and range

Flying needle inspection machine:

High testing accuracy, able to accurately locate any testing point, with good detection capability for high-density and fine pitch circuit boards.

The testing scope is wide, suitable for circuit boards of various sizes, shapes, and complexities.

A multimeter:

The testing accuracy depends on its internal circuit design and functional modules.

The testing scope is limited, usually only measuring basic electrical parameters in the circuit.

4、 Application scenarios

Flying needle inspection machine:

Widely used inSMTThe surface mount technology industry, especially in high value-added circuit board testing such as automotive electronics, aerospace, military, consumer electronics, medical electronics, etc.

Especially suitable for small batch and multi category board testing scenarios.

A multimeter:

It is an essential instrument in electronic laboratories, commonly used for basic circuit measurements.

Suitable for the maintenance, debugging, and research and development processes of various electronic products.

5、 Cost and Efficiency

Flying needle inspection machine:

The initial investment is relatively high, but the testing speed is fast, especially when testing high-density and complex circuit boards, which has significant advantages.

No need to create expensive specialized testing racks, which can effectively save costs for new product development, sample validation, or small batch production stages.

A multimeter:

Relatively affordable, easy to purchase and use.

But the testing speed is slow and requires manual operation and point by point measurement.

In summary, flying needle inspection machines and multimeters each have their unique advantages and application scenarios in the field of electronic testing. The flying needle inspection machine has become the preferred tool for circuit board testing due to its high precision, high efficiency, and wide testing range, while the multimeter has become an essential tool for electronic engineers and maintenance personnel due to its portability, ease of use, and basic measurement functions.
