Faked Marking Permanency Legend

A common counterfeit component practice is to simply re-print the information on the top of electronic components, by a process known as Blacktopping. By using a closely followed process we can determine whether this has been carried out on electrical components. Normally the devices will actually have the correct part number, but the date codes, the lot codes or the speeds will be remarked to make the components appear as different items.

This is a fairly crude process, but without proper investigation, this can catch out the end customer and is normally a sign that parts have been harvested from PCB’s. Retronix certified can help you detect thes counterfeit components and remove them from your supply chain.
