Title: Apple Implements Tiny QR Codes to Track Defective Screens for Improved Manufacturing Efficiency

Apple, renowned for its focus on quality control, has reportedly introduced small QR codes on iPhone displays to monitor the number of defective screens discarded by suppliers. This groundbreaking implementation aims to streamline the manufacturing process and significantly reduce wastage due to manufacturing errors.

The tiny QR codes come in two variations, with one being the size of a grain of sand and only visible with special equipment. The other variant is discreetly located on the inside of the display along the bezel. Apple has invested millions of dollars in developing this barcode process and installed cutting-edge laser scanning equipment at Lens Technology and Biel Crystal, the two manufacturers responsible for producing the iPhone’s cover glass.

By utilizing this innovative system, Apple now maintains an accurate count of every piece of glass produced by its suppliers and can track the quantity of material wasted due to defects. Initial results from the implementation of barcodes revealed that three out of every ten cover glasses were being discarded due to manufacturing errors. However, with relentless pressure from Apple, the suppliers have successfully reduced this number to merely one in ten.

This remarkable reduction in manufacturing errors has saved Apple hundreds of millions of dollars, as it directly pays for production. Since 2020, Apple has been employing barcode technology on various iPhone components to optimize manufacturing operations. With the introduction of QR codes on displays, Apple now has the capability to determine the specific manufacturer and production date of the glass, enabling better tracking of production levels and yield rates.

The implementation of barcodes on displays involves a complex, multi-step procedure to ensure their accurate placement. This meticulous process is vital to guarantee the efficiency of defect tracing and leak identification, thus bolstering Apple’s commitment to delivering high-quality products to its consumers.

While Apple has been utilizing barcodes for other iPhone components, such as tracing defects or identifying leaks, this marks the first time they have been incorporated into displays. The company continues to lead the way in harnessing technology to enhance manufacturing processes and strives to set new standards in the industry.

With the successful integration of these cutting-edge QR codes, Apple is setting a precedent for the future of manufacturing efficiency. As the company continues to prioritize quality and reduce waste, consumers can expect even higher standards in their favorite Apple devices.
