- How to Mark High-Scannability DPM QR Codes on Metal: Fiber Laser & Etching Guide Jul. 27, 2026 Direct Part Marking (DPM) on metal components is essential for full-lifecycle traceability in automotive, aerospace, and heavy industrial manufacturing. However, etching readable 2D barcodes directly onto raw steel, aluminum, or mac...
- How to Print Micro QR Codes on PCB Boards That Always Scan Successfully Jul. 22, 2026 Marking small 2D codes on Printed Circuit Board Assemblies (PCBAs) is critical for SMT component tracking and full lifecycle traceability. However, fitting a Micro QR code into a tiny 2" mm"×2" mm" space creates big heada...
- How to Improve QR Code Scannability on Flexible Films and Plastic Packaging (2026 Guide) Jul. 20, 2026 Flexible films (BOPP, PET, PE) and rigid plastics present unique hurdles for 2D barcode verification. Non-porous surfaces, low surface energy, and specular reflection frequently cause unreadable QR codes, leading to ISO/IE...
- How to Prevent Industrial Printer Nozzle Blockages During Long Shutdowns (TIJ vs. CIJ) Jul. 15, 2026 Extended production shutdowns—whether for seasonal maintenance, holidays, or line reconfigurations—pose a significant threat to industrial coding solutions. If left unmanaged, fluid stagnation inside an industrial inkjet printer leads t...
