Redistribution Layer重布线层

A redistribution layer (RDL) is an additional thin-film metal and dielectric routing layer formed on a die or wafer to reroute I/O pads to new locations for finer pitch, different bump patterns, or package compatibility before bump formation. In localization, the term appears in advanced packaging design documents, wafer-level packaging process specifications, assembly drawings, and DFM guidelines that describe fan-in or fan-out interconnects.

Where this term appears

Localization teams see redistribution layer in packaging design reviews, wafer-level packaging process flows, and cross-section diagrams. It occurs in strings such as 'RDL first', 'RDL last', 'RDL dielectric', and 'RDL trace width' within process specifications and equipment documentation. Translators must keep the abbreviation RDL stable while adapting the expanded term according to approved terminology.

The mistake that shows up most often

A common error is translating redistribution layer word-by-word as 're-distribution layer' or 'distribution layer' without conveying the routing function. This creates vague process documentation, especially where RDL is used for pad relocation. Another issue is inconsistent use of the abbreviation and full term: some documents use the localized expanded term after first mention, while others retain 'RDL', making cross-reference between design and process documents harder to follow.

Why consistent rendering matters

Terminology must stay consistent across datasheets, design kits and patent filings. A single inconsistent parameter can propagate into fabrication decisions or weaken a patent claim, and IP confidentiality applies to every document in the chain.

Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
