 Land

Also called a pad. This is a base for soldering provided on a PWB to facilitate attachment of

the lead or electrode.

 Lead

A conductor attached to the edge of a component. To mount a component, this part is

soldered and bonded to the PWB.

 Machine coordinate origin

The OCC recognizes the first mark being a common mark. After the recognition, the OCC of

LF/RF moves to the left front section of each station as viewed from the front side of the

machine. and the OCC of LR/RR moves to the right rear section of each station as viewed from

the front side of the machine.

With this, the return-to-home operation is finished. The OCC position of LF/RF at this time is

the origin on the coordinates. That is, the position of (X=0, Y=0), based on which development

will be made to each coordinate.

At the return-to-home operation, the OCC recognizes the first mark being a common mark,

where the distance from origin to the first mark has been defined on the software, and thus we

can find how the first mark is slipped from the design dimension compared with that distance.

At this moment, an offset is caused from the difference between the slippage of the X, Y marks

and the design dimension, and it returns to the post-correction coordinate origin. This position

will be the accurate coordinate origin.

 Mounter

A surface-mounting component placing machine. This is a machine that places electronic

components at the given position on a printed wiring board.

 MTC

Abbreviation of Matrix Tray Changer

This is a device that supplies a main unit of an RS-1/1R with components from a tray. A head

inside of the MTC pick up a component from a tray, and then places it on a unit referred to as a

shuttle. The shuttle picks up a component from the bottom side with vacuum, and then moves

it into the main unit of the RS-1/1R (referred to as “the machine” hereinafter). A head of the

machine picks up the component from the shuttle, and then places it on a board.

Two types of MTCs are provided, TR6D and TR6S. The TR6D/6S is supposed to be installed

on the right side of the machine. When the same type of components are set on both of the

upper and lower racks of the TR6D, Non-stop operation (that is, when components run out on

the lower rack, components are supplied from the upper rack while you can supply the lower

rack with components) becomes available.

 MTS

An abbreviation for Matrix Tray Server.

This is a feeder unit for tray components. The tray is pulled out into the unit and the head of

the unit picks and places each component directly.

A TR8SR can be attached on the same bank together with other types of tape feeders (up to 20

8-mm tape feeders).

 Nozzle

A nozzle is a jig to be used when the head picks up and place a component.

During production, each head goes to the ATC to get a nozzle that fits each component

(picking surface), and using that nozzle, the head picks up and places the component.

 OCC

An abbreviation for Offset Correction Camera.

This camera performs teaching of BOC mark, and teaching of recognition, placement and

pick-up positions.

 Off-line

Off-line means a state of the system currently not under communication of computer.

 On-line

On-line means a state of the system currently under direct control of computer.

 Origin return

Origin return is an action to detect the coordinate origin (X, Y), the origin (zero phase) of head

(Z, θ). Execution of this function supplies the servo current to each motor (X, Y, Z, θ).

Namely, production operation and others cannot be performed without this operation.

Usually, a notice is given immediately after the power supply is turned on and then this

operation is performed. If this notice is ignored, use the “START” button to perform this

operation.

 Pick Data

Pick data is data related to picking including the position, angle, etc. where each component is

set. An accurate pick position is obtained by using [Teaching] in the operation area.

 Picking

Picking means a series of action for the head to take a component from the tape or tray in such

a manner that the head moves to the picking position, and then picks up the component by

means of vacuuming, which is the reason why it is called picking.

 Pitch

Pitch basically indicates the dimension from a center to another center of something to be

viewed. For a lead pitch, enter the X, Y dimensions of the center of a lead to the center of the

adjacent lead, and for a pitch between circuits, enter that of the center of a circuit to the center

of the adjacent circuit.

 Placement

A series of actions made by the head to move the picked up component onto the PWB and to

put the component on the given position of PWB is called placement.

 Placement data

Based on the PWB origin, which has been set by the previous PWB data, the information on a

placement point is entered in this placement data. An accurate placement position can be

obtained by “Coordinate teaching” by using [Teaching] in the operation area.

 Placement station

A PWB positioning section. This is a unit that fixes a printed wiring board to the given position.

 PLCC

An abbreviation for Plastic Leaded Chip Carrier. Also expressed as QFJ.

A component with J-shaped leads each on four sides. Components of this type are suitable

for automatic placement owing to its high lead position accuracy and resistance to deformation.

 Program (production program)

This is an aggregation of commands and mounting position data to mount electronic

components on a printed wiring board.

 PWB data

In the PWB data, enter the recognition method when BOC marks are used, and PWB

information such as PWB home position. When BOC marks are used, the mark information is

transmitted to the machine by “Recognition teaching” by using [Teaching] in the operation area.

 PWB origin (the coordinate origin)

PWB origin is the origin to develop a BOC mark, a placement center position and so on.

Although we do not have any specified position for the PWB origin, it should be basically placed

on the PWB. If CAD data is present, the CAD origin will be the PWB origin on the program.

The coordinate system basically takes the left-hand direction as −X, the right-hand direction as

+X, the upward direction as +Y, and the downward direction as −Y viewed from the origin.

 QFP

QFP (Quad Flat Package) means a component of gull-wing shape with leads in four directions.

The lead pitch is more shortened as the number of pins increases. It is featured by that it is a

small package suitable for products with a number of required leads and that appearance

inspection of solder connections is easy.

 SOJ

SOJ (Small Outline J-bend Package) means a component of J-bend shape with leads in two

directions. It is featured by high resistance of leads against deformation, easy handling, and

low thermal resistance.

 SOP

SOP (Small Outline Package) means a component of gull-wing shape with leads in two

directions. The features are: small size, small mounting area on PWB, easy visual inspection

of soldered connections and also easy correction with soldering iron.

 Square chip

A square chip means a square component or similar one such as 1005 (width of 1.0 mm ×

height of 0.5 mm) and 1608 (width of 1.6 mm × height of 0.8 mm). Square chips include

different types such as resistance and capacitor.

 Support table

A unit to support the printed wiring board.
