(B01_04) Component weight [mg]

Set the component weight in the text box.

(B01_05) Polarity existence

Set "Enable" or "Disable" to determine whether or not the component has a

polarity (direction).

This data is used for optimization of the pattern program.

Select "Enable" or "Disable".

(B01_13) Electrical Contact Data

Set the basic parameters related to the electrodes of the components.

(1) Grid Type

Select one of the following grid types.

Regular : Regular Lattice

Custom : Lattice having no electrodes at 4 corners

Checker : Staggered Array

Reversed Checker : Reversed Staggered Array

(2) Image

Select one of the following options depending on how the image of the

electrode is captured in comparison with the mold.

Bright : Select this when the captured image looks brighter than

the mold.

Dark : Select this when the captured image looks darker than the

mold.

(a) In normal cases, select "Bright".

(b) When the mold of a BGA component is made of ceramic, it might be

better to select "Dark".

(3) Elctd type

Select one of the following options as an electrode type.

Ball : Select this when the electrode type is "Ball Grid Array".

Land : Select this when the electrode type is "Land Grid Array".

(4) Extended setting

Select "Enable" or "Disable" to determine whether or not the extended

data should be used.

When "Enable" is set in the "Extended setting" text box, the extended

data such as information on missing electrodes can be specified.

The following shows the extended data that can be specified.

Missing Elctd Set {

The above parameters must be specified when "BGA/CSP (Simple)" is

selected.

(5) # of types

Set the number of electrode types in the text box.

• Data Input Range

1 to 3

(a) The above parameters must be specified when "BGA/CSP (Simple)"

is selected.

(b) When several types are specified, it becomes possible to handle

such components that have electrodes of different diameters.

(6) # of groups

Set the number of electrode groups in the text box.

• Data Input Range

BGA/CSP (Simple) : 1 to 30

BGA/CSP (Complex): 1 to 2000

When the formation of a special BGA cannot be expressed by a certain

array type, such a BGA component can be used by increasing the

number of electrode groups.

Groups can be overlapped with each other.

Example : The balls arrayed in the 1st and 6th row are shifted by

half a pitch, compared with the balls in the other rows

(2nd through 5th rows).
