High-Precision Marking Project for the Electronic Components Industry

 

The client company in South America specializes in the production of miniature electronic components (such as PCB boards, chips, and capacitors), with product sizes as small as 2mm x 2mm.  They require printed codes for supply chain traceability, with a daily production volume of 5 million units.

 

Insufficient High-Precision Printing: The existing inkjet printer has a resolution of only 300 DPI, resulting in blurry prints and a scanning failure rate of 15%;

Poor Scratch Resistance: Electronic components undergo high-temperature soldering (260℃) and alcohol wiping during assembly, causing the printed codes to easily detach (10% detachment rate);

Data Synchronization Lag: Inability to connect to the manufacturing execution system requires manual import of production data, taking an average of 3 hours per day;

Difficulty Adapting to Small Components: The small size of the components and the low positioning accuracy of the existing print head result in a 5% printing offset rate.

 

Added sensors (accuracy ±0.01mm) to automatically correct component position, reducing the offset rate to below 0.1%.

Customized Consumables: Industrial-grade scratch-resistant ink

UV Invisible Ink Curing Scratch-Resistant Ink: Curing time ≤1 second, resistant to 260℃ high-temperature soldering, resistant to alcohol wiping (no detachment after 50 times), and compliant with RoHS standards;

Ink Viscosity Control: Built-in viscosity sensor to adjust ink viscosity in real time, adapting to the printing needs of miniature components.

 

Improved Accuracy: Scanning success rate increased from 85% to 99.95%, improving component assembly efficiency by 12%;

Improved Scratch Resistance: Printing detachment rate reduced to below 0.5%, meeting electronic industry high-temperature soldering standards;

Optimized Efficiency: Manual data import time reduced to zero, increasing daily production by 800,000 units (a 16% increase);

Cost Savings: Component scrap rate due to printing errors reduced from 3% to 0.1%, saving over $30,000 annually.
