PWB clamping method

This is a method for using the bottom side of a board as a reference to clamp both the

edge of the fixed side and that of the movable side with the clamp bars from above..

PWB width adjusting methods

- Standard :Manually adjusting method with your hand

- Option :Automatic PWB width adjusting method via a motor

(Minimum board size: 50.0 mm × 50.0 mm)

PWB buffer

The machine is not equipped with any buffer as a standard device. When you add the

IN/OUT buffer option to the machine, the machine uses three buffers.

See Section 5.2.10 “IN/OUT buffer” of Chapter 5 “Standard Functions and Optional

Functions” for details

4.7.6 Function for correcting the PWB positions

Field of vision for recognizing the PWB reference marks

6.3 mm (camera’s field of vision for recognition).

Figure Field of vision for recognizing the PWB reference marks

Window size for recognizing the PWB reference marks

This size can be changed within a maximum of 6.3 mm, subject to securing a clearance

between the recognition mark and its surrounding area.

Kinds of recognition marks and corrective method

- PWB reference mark

Two or three marks are located on a PWB to correct the entire PWB.

When the machine detects two PWB reference marks, it corrects the positioning,

angle and expansion/contraction of the entire PWB. When detecting three PWB

reference marks, it corrects the perpendicularity in the X and Y direction also.

- Component positioning marks

If a component such as an IC (QFP) needs to be placed on a board very precisely,

two or three marks set on the component itself are used to correct each component

placement position.

- Marks used to position the component area

Two marks (their positions can be set as you like) are to be provided to a group of

components placement positions, and they are used to correct each component

placement position in the group.

Note 1: You can set a mark at any position. However, if three reference marks are set, they

must not be aligned with one another. (It is recommended that these marks be set at

corners of the board.)

Note 2: When the machine supports feeding of a board whose size exceeds 610 mm

360 mm

twice, one set of two or three reference marks is required for each feeding operation

(total four or six marks). When it supports optional feeding of a board whose size

exceeds 1,200 mm

360 mm three times, one set of two or three reference marks is

required for each feeding operation (total six or nine marks).

Figure Reference marks and components positioning marks

Basic quality of recognition marks

- Copper not coated or coated

- It needs to have a clear contrast between the recognition mark surface and the print

wiring quality.

- It needs to have neither oxidation nor quality deterioration of the recognition marks.

Coating the recognition marks

The recognition mark surfaces shall all be coated as follows：

- Transparent antioxidant coating - Solder plating

- Nickel plating - Gold plating

- Tin plating - Hot-air levelling solder coating

Marking forms

- The standard marks represent the thirteen (13) forms as shown in the following

block, “forms of recognition marks.”

- For any mark other than those shown in the said block, customers shall make

templates to allow for recognition through a pattern matching.

Note 1: Limited to the standard marks only

；

and any area fiducial mark is excluded

from the subjects.

Note 2: Within a field of vision, there should be no similar form pattern other than the

subjected form patterns.

- For regular triangles, checker patterns and users’ templates, the 90°up-side-down

marks can also be recognized.
