8 Product / PCB

8.1 PCB Editor

The PCB Editor enables the user to give a hierarchical description (pyramidal structure) of the PCB to be

assembled.

The PCB Editor is subdivided into the following sub-editors:

- Structure Editor

The Structure Editor provides the user with an overview of the overall structure of a PCB. It is

possible to create new PCB types and to edit existing ones.

As an option, the entire PCB including all placement positions, fiducials, ink spots, coordinate

systems, etc. can be represented graphically in the display area of the Structure Editor.

- Cluster Editor

The Cluster Editor serves to define or edit the basic data (cluster data) of a PCB.

- Placement Position Editor

The Placement Position Editor describes the location of the placement positions.

- Fiducial Editor

Fiducials, fiducial sets and ink spots can be defined or edited in the Fiducial Editor.

8.1.1 Description of a PCB

8.1.1.1 PCB Data

The PCB data can be categorized into source data and process-specific data.

- The source data contain the description of a PCB.

- The process-specific data are generated from the source data for a given system, i.e. for a given

setup selected by the user.

8.1.1.2 PCB Source Data

- PCB Type

The PCB type contains the basic description of a PCB type consisting of data for clusters, fiducials,

component positions as well as cross-references given to other descriptions of partial PCB structures.

Sample file name of PCB type "A": A.lb

- Partial PCB Structure

This partial PCB structure contains the PCB type description as well as its coordinate data

(see Fig. 8.1.2).

Sample file name of partial PCB structure "A": A.lp

- Overall PCB Structure

When the generated process-specific data are added to the source data, then all data required for

assembling the PCB are available.

Sample file name of overall PCB structure "A": A.la
