6 - Recipe Creation Step by Step for 2D

Recipes

Creating 2D X-ray inspection recipes are very similar to creating AOI inspection recipes. Here

are the basic steps:

6.1 Step1: Prepare CAD data

Although CAD data is not absolutely necessary to create inspection recipes, it certainly helps to

speed up the recipe creation process. First, convert the CAD data to YCD format (Nordson

YESTECH Cad Data) before importing to the machine. Microsoft Excel can be used for the

formatting tasks. More specialized CAM software, such as CircuitCAM, can also be used for the

tasks. To facilitate system installation and training, Nordson YESTECH recommends using

Microsoft Office on the computer. Nordson YESTECH supplies a conversion utility in the form

of an Excel macro to convert any column data into YCD format. The utility can be found in the

following folder. C:\Aoi_Data\CAD_Data.

YCD files are ASCII text files. There are two main sections in the file; Header and Part List.

The header section looks like this:

.YESTECH_CAD

[Header]

Version= 1

RecipeName= gdc-060p027002rev_k.rcp

ScaleFactor= 1000.000

IsTopSide= 1

All items in the header are optional. If specific information is not provided in the YCD file, the

default value is used. If there is no board size information available, the software prompts the

user to define board size.

Version

Version of the YCD file should always be 1

RecipeName

Name of the inspection recipe.

ScaleFactor

Scale factor used for the XY position should

be 1 for um, 25.4 for mil, 1000 for mm and

25400 for inches.

InvertXPos

Can be 0 or 1 to indicate if the X positions

of the part are inverted.

InvertYPos

Can be 0 or 1 to indicate if the Y positions

of the part are inverted.

RotationDir

Part rotation direction can be 1 for counter

clockwise or -1 for clockwise.

RotationOffset

Rotation Offset this value is added to the

rotation parameter of every part.

BoardWidth

The Width of the board.

BoardHeight

The height of the board.

BoardRotation

Can be 90, 180 or 270 which indicates the

physical rotation of the board relative to

the CAD orientation.

PNLib

File path to the local Part number library.

CentralLib

File path to the central library.

PkgLib

Specifies which standard package library to

use.

PkgNameMap

Specifies the package name map file. Package

name map converts the package names used in

the CAD data to that of the standard package

library.

IsTopSide

Can be 1 or 0 to specify if this is the top

or bottom side CAD data.

The part list section lists the information for every part.

The following information is required:

 Part Reference ID

 Part Number

 X Coordinate of the part center

 Y Coordinate of the part center

 Part Rotation

The following information is recommended:

 Part Package

 Part Description

The Nordson YESTECH CAD Utility gathers header information from the graphical user

interface and collects CAD data in any column format to generate the YCD file. The following

are some of the screen shots of the CAD utility.
