There are 3 main potential elements to any Direct Part Mark application. These are Mark – Verify – Read.
Initially, the code has to be marked in some way and the method is dependant on the material to be marked, the required lifespan of the mark, the accessibility of the area to be marked, production speed / volume etc. The most common methods of marking are Laser-etching, Dot peening, Ink-jetting and Chemical-etching.
Verification is required in many instances to check the quality of code, particularly at time of marking. This can provide immediate feedback as to any changes to the marking process. For example, the verifier can monitor tip wear on a dot peen machine by monitoring dot size, and flag the operator on the floor when a pin should be changed.
At the marking stage, during the manufacturing process and throughout the products lifecycle, the mark will be required to be read. Depending on the situation and the environment, this could be with a handheld reader tethered to a host computer or with a remote Bluetooth connection. The information could be gathered with a Mobile Computer with inbuilt reader and wirelessly transmitted back to the host. Fixed Position readers are used for automatically collecting the data on some form of automated transfer or a presentation type reader used in an application where the user needs to be “hands-free”.
