Chamfered Corner
|
|
Used for rapid orientation in fixture during processing.
|
|
|
|
|
Used for part or surface identification. This is typically alphanumeric characters, but can be barcode, etc.
|
|
|
Scribed Edge
|
|
Somewhat rough edge remaining after snapping. Normally 2-3 mils larger than initial dimension. Most cost effective sizing technique when tolerance permits.
|
|
|
Machined Cut-Out
|
|
Used in edge metalization, (slots), access ports or to conform to assembly layout.
|
|
|
Drilled Hole
|
|
Used to make front-to-back connections; (vias), mounting holes or access ports, (feed-thrus).
|
|
|
Scribe Line
|
|
A series of laser pulses (normally 4-6 mils apart) typically 35-50% of substrate thickness. Allows for multi-up arrays that are easily snapped into single devices after processing. Tolerance after snapping, +/- 3 mils typical.
|
|
|
Machine Alignment Flats
|
|
Used for precise location with 3-pin fixture. Flat edges provide repeatable positioning. Flats are 2-3 mils deep on parts lasered from larger blanks. They are 15 +/- 10 mils deep when lasered in as-fired edges.
|
|
|
Origin
|
|
The point of reference for all internal features. Normally a corner of the part or the alignment flat intersection when present.
