As a result, manufacturers must rely on additional files and manual interpretation, which increases the risk of errors.<\/p>\n<p data-start=\"1877\" data-end=\"2069\">IPC-2581, on the other hand, is a fully intelligent format.

Since all information is included in one file, there is less chance of mismatch between Gerber, BOM, and pick-and-place data.<\/p>\n<p data-start=\"2370\" data-end=\"2524\">Second, it improves efficiency.
