first component, please modify this line firstly. See the Figure 4.10

Find and confirm one component’s coordinate by using the function of “Movement Mode”-Click

to move (Visual field/Overall Workbench).Once clicked the “Save” item, the interface will

automatic back to main page, then input the corresponding values(Designator refer to the location,

Specification refer to the value of resistance, Footprint refer to the normal package

info,I.e.0603,0805,1206,Etc.Angle value should be set according to the required direction on the

PCB and polarity ,horizontal direction(0 or 180 degree),vertical direction(90 or -90 degree).the

value should be integer. The first component has been completely created after set all above values.

The next step is click “New” item and will pop up one line (completely copy the previous line), then

click “Align” to find and confirm second component (same operation as before)

Change to current position: This is a powerful feature that will change the coordinates of

the entire component list if the board is placed in a different position on the table than the position

that was used to compute the original origin. To use this feature, locate the first fiducial with the

camera. Press “Cancel”, and press “Change to current position”.

The machine will locate both fiducials and compute the offset from the original program. It will

then change the values in the component list to conform to the new board location. After this

process is complete, it is necessary to ensure that the new coordinates for the first component are

entered in the “Left Bottom” location, and that the “Create Panelized List” button is pressed so that

the XY coordinates of the first component appear in all three locations on the screen.

Feeder settings screen

(1)

Feeders Arrangement: Left Feeders (Feeder20-48), Right Feeders (Feeder1-19), Special

Feeders (Feeder49-98). Above feeders’ setting is under the ideal situation. According to the

Required Tape’s width from customers, the quantities maybe be cut down. For example, if there

are a lot of components’ information under the “Chip List” item, choose the feeder number and

you will find the drop-down symbol, will display all components’ specifications by click it. Select

one specification and one less in drop-down list, can do same operation in every feeder.

(2)

Feeder Configuration: Select one feeder, tick the item “Apply”, all configurations will be

unlocked for this feeder, then can-do amendment. Total have five items: Nozzle information, Feed-

box information, Feeder basic information, Tray feeder information, Feeder exchange. One item

will be always locked for Feed-box information and Tray feeder information according to the

differences of components. Operation sequence: Feed-box information (Tray feeder

information)—Feeder basic information—Nozzle information—Feeder exchange (used if placed

wrong tape). See the Figure 4.11.

4.3.1 Nozzle information

Figure 4.11

Figure 4.12

(1) Function: Select corresponding nozzles (one or more than one all acceptable) according to the

components and the nozzle have set on the machine, then the machine will automatic assign to

each feeder in order to meet the requirements of single head work or multi heads working together.

Also, have detect functions on this item. See the Figure 4.12.

(2) Align: The nozzle will align to the component’s upside on corresponding feeders when click

this item

(3) Height: After clicking this item, the nozzle will go down and check whether the pick height is

ok. Support do adjustment of pick height on feeder information item if needed.

(4) Pick: After clicking this item, the corresponding nozzle will pick one component and check

whether pick position is ok. Support do adjustment of pick position on feeder information item if

needed. After this feature is activated, the part should be removed from the nozzle with a finger or

tweezers.

(5) Threshold For each feeder, check the nozzle(s) that are sized appropriately for the component

installed in the feeder. We recommend leaving the threshold settings at their default values,

because the vacuum detection feature to which these settings relate is rarely needed or used when

the vision system is active.

Feeder information

Figure 4.13

Function: Adjust the value for feeder and peeler, see the Figure 4.13

Peel Strength: Support do adjustment according to different components’ required strength, default

value 100

Feed rate: Adjust the feed & peel distance by changing the value

Feed torque: Adjust the feed strength by changing the value, default value 60

Feed test: After finishing above steps, can click this item to test the feed status

4.3.2Feeder Basic information

Figure 4.14

(1) Pick X/Y: First have to lock the position of component on the feeder, once saved the

modification, the XY date will automatically change to the ones after alignment. See the Figure 4.14.

NOTE: For feeders installed in the far back of the machine (often feeders 18 and 19 on the left side)

the camera, which is mounted on the front of the head, will not be able to be moved far enough to

view the necessary location. For these feeders, after clicking “Align”, select the desired nozzle as

the “Alignment method” on the right side of the screen. Then use the mouse to move the nozzle to

the desired pick location, and slowly pull the vertical slider down to lower the nozzle. Continue to

fine-tune the location of the nozzle until it is centered in the hole in the tape. Click save.

(2) Pick Angle: The initial default angle of the right-side feeders is 90 degrees, the initial default

angle of the left side feeders is -90 degrees, normally does not need to be changed because the

machine automatically sets this value based on the feeder’s location on the left or right rail. For

trays and sort tapes, however, this value may need to be changed to 0 or 180.

(3) Footprint: Select corresponding footprint, when use the function “Vision Alignment”, will refer

to the values in date base. If the correct size is not in the menu, it is possible to create new footprints

by entering the footprint library.

(4) Vision Alignment: The Vision Alignment setting is normally set at “Individual.” This setting

directs the NeoDen4 to transport each “picked” component to the upward-looking camera to ensure
