Abstract
Description
Technical Field
[0001] This invention relates to the field of semiconductor packaging technology, and in particular to a process control system for the production of single-sided roll-to-roll ultra-small window FCOB packaging substrates. Background Technology
[0002] With the continuous development of display technology, the requirements for display devices are becoming increasingly stringent. These requirements not only demand higher resolution and thinner profiles but also larger display areas. To meet these needs, display device manufacturing technologies are constantly innovating and developing. Among these, FCOB (Factory-on-Board) technology has gained widespread application due to its ability to directly mount chips onto the substrate, reducing packaging space and thus contributing to the miniaturization and thinning of display devices. Currently, traditional FCOB packaging technology typically uses double-sided carrier boards for chip mounting. Furthermore, current windowing technology utilizes lasers, with the laser trajectory consisting of an outer frame and an arc-shaped path, spaced 30 micrometers apart.
[0003] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:
[0004] The use of double-sided substrates makes it difficult to achieve ultra-small window designs, limiting the miniaturization of display devices. Furthermore, the material and processing costs of double-sided substrates are higher than those of single-sided substrates, increasing production costs. In addition, double-sided substrates increase the complexity of the packaging process, which may lead to a decrease in yield.
[0005] Traditional laser tracing methods struggle to achieve ultra-small window designs, as such precise trajectory adjustments can affect the shape and size of the window.
[0006] The lack of a control system makes it impossible to automate the manufacturing process and ensure that all conditions during the manufacturing process are in optimal condition, which may lead to a decrease in production efficiency. Summary of the Invention
[0007] This application provides a production process control system for a single-sided roll-to-roll ultra-small window FCOB packaging substrate, which solves the problems of high signal delay and inter-line capacitance, poor heat dissipation of electronic devices, insufficient mechanical strength, and light flux loss in the prior art electronic packaging. It optimizes signal transmission speed and system performance, extends the service life of equipment, and has better shock resistance, while improving light flux and overall lighting quality.

[0010] White oil layer, the white oil layer covering the copper layer of a single-sided FPC substrate;
[0011] Its characteristic is that the adhesive layer can block the color of the nanocomposite material layer, so that the chip reflects more light during the light emission process, ensuring the light flux of the entire product;

[0026] S10: Antioxidant treatment using high-temperature resistant OSP solution;
[0027] S11: Cutting, inspection, and packaging;

The laser equipment then performs a windowing operation based on the pre-set parameters and path data. Simultaneously, the equipment's calibration status is monitored to prevent positional shifts due to equipment deviations. Furthermore, the laser trajectory is adjusted to a single arc shape, with the spacing set to 20 micrometers.
