At the top of the dialog, the software suggests setting X-ray power level for BGA inspection.

Move the mouse pointer to an area between the BGA balls and read the gray level at the status

window at the bottom right corner of the screen. The dialog also approximates the pitch of the

BGA. The information can help when selecting Pin Type from a standard pin library (refer to

13.6 Pin Library). Selecting Pin Type is optional and can be left blank if preferred.

Select either Pin Mode or Part Mode. Pin Mode will prompt the user to. The Verify Mode

section of the dialog gives the user the opportunity to re-size and re-position the pin.

By selecting Pin Mode, the user is prompted to verify every pin (this could take some time on a

1000+ pin BGA). When selecting Part Mode (probably most common), the user is prompted to

verify the first pin of every part. Sizing the first pin will set the size for all pins on the part.

Selecting the Set Part Outline checkbox instructs the software to set the part’s size and center

position (purple box) based on the positions of its pins. It should be checked for BGA and

Through-hole connector packages, and unchecked for other packages. It is usually easier to align

the Pin CAD data to greater accuracy than to align the part centroid data of the YCD file. This

feature eliminates the need to spend time adjusting part size during the YCD file import for BGA

and through-hole connector packages.

Selecting the Libraries Update checkbox instructs the software to update the parts, with the

same package, with newly acquired part information. Enable this for all the SMT parts. The only

time you may want it uncheck is for importing pin CAD for PTH parts (e.g. connectors) where

the YCD file contains a pin 1 XY position rather than a centroid XY position.

The Pin CAD import process creates solder inspection boxes for each pin (solder joint) with

Neutral direction and default algorithm (Histogram). User will need to switch them into the

correct algorithm for the inspection. The new inspection algorithm “BGA Pin Inspection” (a

solder algorithm) is designed to replace both BGA group ( a lead algorithm) and BGA Analysis

(a solder algorithm). The BGA Pin Inspection algorithm is currently the most likely algorithm

being used in conjunction with the Pin CAD import feature.

8 - Train Part without CAD data

It is possible to train parts without CAD data. To add parts this way first move the camera so that

the part to be trained is in the field of view, then press the Add Part button on the toolbar.

The Add New Part dialog displays.

Enter the Reference ID of the part to be trained, and select from the Part Number list if the part

is in the part library. If the part is not in the part library, but its package is in the package library,

select the corresponding package of the part. Specify part rotation by selecting from one of the

radio buttons in the Rotation group.

After pressing OK on the Add New Part dialog, specify the part’s exact location by overlaying a

region of interest box on the part.

The Start Right Mouse Auto Repeat Mode checkbox starts the auto repeat mode for adding

multiple parts. See 8.3 Auto Repeat Mode and Quick Marking Check for more detailed

information. The To Recipe Part List and To System Part List radio buttons select which part

list the newly created part is added to. Select the To Recipe Part List for all cases except during

the setup of SmartStart (refer to 17 - SmartStart).

Do not type in the new part number or package on the Add New Part dialog. The Part Number

and Package list boxes can only be used to select from existing part numbers and packages. To

create a new part number use the Edit Part Parameter dialog.

After the Once a part outline box (the purple box) is created around a part, a pop-up menu is

available by right clicking inside the part outline box.

Edit Parameters

Launches the Edit Part Parameters dialog. See Section 8.1.

Train New
