 <Feeding Y Offset> edit box

Used when supplying parts by setting the pitch of the 8mm tape feeder to 4mm.

If the size Y of the part is greater than 2.2mm, the part pickup may interfere with

the tape guide.

In this case, it is possible to set the part pickup position by inputting the Y offset

value in the <Y Offset> edit box. (Input range: 0 ~ 0.5mm)

 <Use the Splicing Skip> check button

The splicing skip function is to supply parts by skipping some parts in the section

where existing tape is spliced with a new tape in the tape feeder since parts are not

supplied at this connected section.

When using this function, select this check box.

 <Splicing Skip Count> edit box

If the splicing check sensor detects a spliced section, parts are supplied by

skipping as many parts as is set here.

 <Splicing Skip Margin> edit box

Inputs the number of parts to be skipped in addition to the part count set in the

<Splicing Skip Count> edit box.

 <Feeding Speed> selection box

Selects the feeding speed of the tape feeder selected from the <Feeder> selection

box.

In the case of a micro part, it may jump up and cause a pickup error during part

feeding. This problem may be solved by reducing the part feeding speed.

 Normal: Supplies parts at normal speed.

 Slow1: Supplies parts at a slightly slower speed.

 Slow2: Supplies parts at slow speed.

 <Part Count/Reel> edit box

Input the default number of parts for the part reel that supplies the corresponding

part. When using the Basic IT function, it is used as default count for the

corresponding part.

 <Reel Transparency> check box

When splicing the tape using transparent tape, this function is selected in the case

that the vision system can detect the tape splicing.

 <Pickup Data> tab

Sets the parameters related to the pickup of the supplied parts.

 <Sync Pickup Tol(%) - X/Y> edit box

When more than two spindles pick parts from the feeder simultaneously, sets the

tolerance for the pick-up position in the X/ Y direction as a percentage of the part

size in the X/ Y direction.

The default value is 15%. If the tolerance for simultaneous pickup is greater than

the default value, simultaneous pickup is performed well, but may cause a pickup

error.

In the case of micro parts, this value must be small, and pocket teaching must be

performed for parts smaller than the 1005 chip to reduce the part dump rate.

Memo Conditions for Simultaneous Pickup

1. The part must be picked up when the center of the head picking a

part is within the tolerance range.

2. In the case of the interlocked heads, the R value must be identical

when picking up a part.

3. The maximum tolerance of the X and Y must be less than 0.5mm.

1: Head Center (Actual Pickup Point)

2: Part Align Point

Here, the tolerance means the offset from the align point of the part to the head

center, which is the actual pickup point.

 <Pick Type> selection box

Select the method to pick parts.

 Normal

Selected in cases to pick a part in the normal manner.

 Virtual Pick

Selected in cases to performs part placement without placing a part actually.

All activities of part pickup and placement are performed using the part center.

However, if the part is long, even though it was placed being held at the

center, both sides of the long part may not come into contact with the PCB

sufficiently.

In this case, this problem can be solved, by pressing the part again so that both

sides of the part or certain section of it may come in contact with the PCB.

As such, this function is useful when performing setup in order to set the

position corresponding to the section with which the specific part already

installed needs to be in close contact without picking up an actual part in order

to have the corresponding part come into close contact with the PCB.

After setting the placement point by using the specific part that needs such

function first, create the next placement point as much as necessary by using
