Marked for Life: A Glance at Some Common Direct Part Marking Methods

Direct part marking is crucial for enabling the traceability of products and the parts comprising them throughout their use. Although each method for applying direct part marks (DPMs) has advantages and disadvantages, they all share one key feature: permanence. Even continuous ink jet, which is considered a “semi-permanent” method of applying DPMs, is sufficiently long-lasting to be suitable for many applications. It’s certainly much better than putting a sticker on an item that could rub off easily.

Do Your DPMs Make the Grade? Understanding the 2D Barcode Verification Parameters in ISO 15415

Direct part marks (DPMs) and other two-dimensional codes can vary widely in their readability. From impeccably formed laser markings to unwieldy dot peen symbols hammered into steel with a worn-out stylus, it’s obvious that some codes will make the cut while others will fail. Because readability is such a major issue, the International Organization for Standardization (ISO) has written up some guidelines – known as ISO 15415 – that specify what a readable code should look like. It turns out that a well-formed, two-dimensional code can be described by eight different parameters.

How X-Mode Brings Out the Best in Barcodes

Barcodes have a unique challenge. Whether printed, etched, engraved or stamped onto their substrate, they’re obligated to remain readable however long traceability is required. This could be anywhere from a few hours to several decades, and the viability of the track, trace and control system depends on them throughout this time. Given that these codes carry essential data through some of the harshest manufacturing environments, it’s no wonder that even the best of them start to fade.
