WARNING 6

Æ Switch the placement machine off at the main switch to remove the dividing plate.

Æ Disconnect the machine from the power and compressed air supply.

Æ Secure the machine to prevent it being switched on again, as described in section 2.10, page

Æ Wait until the operating pressure for the tape cutter has dropped to 0 MPa.

Æ Wear robust protective gloves.

Æ Do not reach inside the used tape channel.

Æ Loosen the two slotted screws (item 4 in Fig. 6.5 - 1).

Æ Pull out the dividing plate.

PLEASE NOTE

Do not position feeder modules with shallow pockets immediately beside bar feeder modules

with deep pockets. The used tapes could overlap and build up.

6.6 Matrix tray changer

The use of flatpack ICs is becoming an increasingly significant aspect in the production of flat

modules. These components are now almost exclusively provided in waffle trays. The space re-

quired by waffle trays is relatively large in comparison to the component density, however. The low

component capacity also requires the waffle trays to be changed frequently, which means that the

placement sequence has to be interrupted if the trays are changed manually.

The use of a matrix tray changer eliminates this unnecessary time loss since the waffle trays are

stored and automatically changed. Programmable, random access to up to 100 x waffle-pack

trays also considerably increases the range of components that can be made available.

6.6.1 Description

The matrix tray changer can be used to store and change up to 100 waffle trays fully automatically.

The levels (storage locations in the towers) for the waffle trays are numbered consecutively in as-

cending order from bottom to top.

The towers move independently of one another in the vertical direction until the selected maga-

zine is within range of the feed axis. The horizontal feed axis transports the waffle-pack tray from

the tower into the access area of the placement head.

Tower 1 has 30 levels, each of which can hold 2 JEDEC trays or one large tray up to 240 x

340 mm² from the waffle-pack tray carriers.

Tower 2 has a capacity of 40 levels for JEDEC trays.

A matrix tray changer may be docked in place of a component trolley at locations 2 and 4 on the

HF machine (only at location 2 on HF/3 machines). The draw-in device installed for the component

trolley may be replaced with the docking device for the matrix tray changer. Or conversely, the ma-

trix tray changer can be replaced with a component trolley.

The matrix tray changer has an integral chassis, and is therefore easy to move to other locations.

It is supplied with the PCB transport height implemented for the HF machines, but can easily be

adapted for PCB transport heights of 830, 900, 930 and 950 mm.
