Description

A flexible electronic component adsorption table

technical field

The invention relates to an adsorption table, in particular to a flexible electronic component adsorption table.

Background technique

Printed circuit technology is to manufacture electronic materials into electronic devices by printing. Combined with flexible electronic technology, such electronic devices can be fabricated on flexible substrates, so that electronic devices have the characteristics of good ductility, lightness, thinness and transparency. It has a wide range of applications in display, thin film solar energy, biomedicine and other fields. Good flexibility and electrical properties are the most important features of flexible electronic components. The flexibility is mainly achieved by flexible materials, and the electrical conductivity mainly depends on the material properties of the film on the substrate and the pattern fabrication accuracy. Based on influencing factors such as electrical conductivity, manufacturing process and manufacturing cost, the three most commonly used materials in circuits are copper, aluminum and silver. These three types of materials all experience electromigration in traditional silicon-based integrated circuits.

In flexible electronic printed circuits, copper and silver materials are currently mainly used for production. In addition to circuit failure caused by mechanical damage, corrosion, and high temperature, the electromigration failure phenomenon still cannot be ignored. At this time, the phenomenon of electromigration is more complicated than that in rigid circuit substrates. At present, the electromigration test of flexible circuits is usually performed manually by manually completing the power-on process, and then using a scanning electron microscope to observe and analyze the failure state. Defects that cannot be automated can no longer meet people's requirements.
