Precisely Control Liquid Level, Safeguard Panel Etching Yield ——Oriental Approach Intelligent Liquid Level Detection Solution
In the precision - driven field of panel manufacturing, every 0.1mm fluctuation in the liquid level can potentially become an "invisible killer" of yield. When a Gen 10.5 substrate, with its size of 3370mm × 2940mm, is immersed in the etching solution, even a tiny shaking of the liquid surface can escalate into issues such as uneven etching, bubble defects, or over - etching on the edge of the entire substrate, directly leading to batch scrapping. Now, the Oriental Approach high - precision liquid level detection equipment is here. With micron - level monitoring accuracy, it builds the "first line of defense" against liquid level fluctuations for you, making yield losses a thing of the past.
Why must panel factories pay attention to liquid level detection?
The yield pain points in the panel etching process often lie in the imperceptible liquid level fluctuations:
When the liquid level fluctuation exceeds 0.3mm, the deviation in etching depth between the edge and the center of a Gen 10.5 substrate can reach more than 50nm, directly causing ITO residues (bright spots) or metal wire breakage.
The tearing of the boundary layer caused by turbulence can result in a 30% difference in etching rate on the same substrate, ultimately manifesting as "light and dark stripes" on the display panel.
Un detected abnormal liquid levels may cause an entire batch of substrates (with a single batch value exceeding one million yuan) to be scrapped due to excessive defect rates.
Traditional liquid level detection methods (such as float sensors and single - point lasers) can no longer meet the needs of high - generation production lines. Their response lag, detection blind spots, and lack of flatness monitoring allow liquid level fluctuations to erode yield "unnoticeably".
Oriental Approach liquid level detection equipment: Redefining "stability" in panel etching
We have been deeply engaged in the panel manufacturing process for 10 years. Aiming at the core pain points of large - size substrate etching, we have developed an "all - round perception + real - time response + intelligent early warning" liquid level detection system, making every etching process accurate and controllable.
1. All - round and dead - angle - free monitoring, capable of capturing even millimeter - level fluctuations
Multi - dimensional sensor network: 6 - 8 sets of high - precision laser sensors are deployed around the etching tank, with an accuracy of ±0.05mm. They simultaneously monitor the liquid level height, flatness, and fluctuation frequency, eliminating hidden problems such as "local inclination" and "underlying turbulence".
Ultra - fast response: The sampling frequency is as high as 1000Hz, which can capture tiny disturbances of the liquid surface (such as ripples when the substrate is immersed) within 0.1 seconds, reserving sufficient reaction time for the subsequent liquid level regulation system.
2. Empowered by intelligent algorithms, from "detection" to "prediction"
Fluctuation trend prediction: Equipped with an AI learning algorithm, it can predict the risk of liquid level fluctuation 0.5 seconds in advance by analyzing historical data (such as substrate immersion speed and liquid supply pressure changes) and trigger pre - adjustment instructions.
Defect correlation analysis: It automatically correlates the defect data of the etched substrate (such as the position of bright spots and the deviation of etching depth), generates a "liquid level fluctuation - defect mapping report", and reversely optimizes the process parameters.
3. Seamless integration with the production line, making yield improvement visible
Compatible with all - generation line equipment: From Gen 6 to Gen 12 production lines, it can be quickly deployed without modifying the structure of the etching tank. It supports real - time linkage with mainstream liquid level control systems (such as PID regulation modules), stably controlling the liquid level fluctuation within ±0.2mm.
Data visualization management: It uploads liquid level data in real - time through the MES system and generates a "correlation report of etching batch - liquid level stability - yield", making every bit of yield improvement traceable and reproducible.
What will you gain by choosing us?
Direct benefits: Yield increases by 1.5% - 3% (taking Gen 10.5 line as an example, the annual increased revenue exceeds ten million yuan), the defect rate is reduced by 40%, and rework and scrapping caused by liquid level problems are reduced.
Hidden value: The stability of the process is improved, reducing parameter debugging time (single model change efficiency is increased by 20%), and extending the service life of the etching solution (reducing chemical consumption by 10%).
Lifetime guarantee: 7 × 24 - hour technical support, regular on - site calibration (to ensure long - term stability of sensor accuracy), and free algorithm module upgrades (to adapt to future higher - precision process requirements).
Take action now to seize the opportunity of yield improvement
The competition in panel manufacturing has long entered the stage of "micron - level precision" rivalry. Instead of worrying about the defect rate afterwards, it is better to control the liquid level stability from the source. From now on, those who make an appointment for a demonstration can receive the "liquid level fluctuation optimization scheme evaluation" service for free. Let us prove with data how much a 0.1mm precise control can bring to your production line.
