IC Lead Measurement Background

The lead spacing of IC (integrated circuit) components is one of the most important indicators of their performance and reliability. With the rapid development of modern electronic technology, the lead spacing of IC components is getting smaller and smaller, and the requirements for measurement accuracy are getting higher and higher. Traditional measurement methods may not be able to meet the demand for high accuracy and efficiency, so more advanced measurement tools and techniques need to be introduced.

Principle of Spectral Measurement

POMEAS Point Spectrum Confocal Sensors work by emitting a beam of light of a specific wavelength to the surface of the object to be measured and receiving the light reflected back. By measuring the angle and intensity of the light reflected off the surface of the object, information about the size and shape of the object can be calculated. For IC lead spacing measurements, the sensor can accurately measure the width of the leads and the distance between neighboring leads.

Spectral Measurement Advantages

(1) High accuracy: POMEAS point spectrum confocal sensors have measurement accuracy up to the micron level, which meets the need for high accuracy measurement of IC lead spacing.

(2) Non-contact Measurement: The sensor measures by light, which does not cause any damage to the IC components and avoids the errors that may be introduced in traditional measurement methods.

(3) Automated measurement: the sensor can automatically complete the measurement process, greatly improving the measurement efficiency and accuracy. Meanwhile, data storage, analysis and report generation can be conveniently realized through computer processing of data.
