4.13 Aligning

NOTICE

Target group: standard operator

The procedure described is a regular task that can be carried out by any trained operator.

You need the following tools to align the LDU:

●

Allen key 3 mm

●

Allen key 10 mm

The screws for aligning the LDU are easily accessible from above:

1. Rear fixing screw (Allen screw 3mm)

2. Rear adjustment screw (Allen screw

10mm)

3. Front fixing screw (Allen screw 3mm)

4. Front adjustment screw (Allen screw

10mm)

Each of the two pairs consisting of fixing screw and adjustment screw is arranged concentrically.

► Loosen the two fixing screws (1) and (3) with an Allen key of size 3mm.

► Align the dipping plate with the two adjustment screws (2) and (4) (Allen key 10 mm).

Rotating one of the adjustments screws clockwise will lift the dipping plate at this position.

Rotating one of the adjustment screws counterclockwise will lower the dipping plate at this position.

One revolution of the adjustment screws corresponds to lifting or lowering by 0.5mm.

► Tighten the two fixing screws (1) and (3) with a maximum torque of 0.75Nm.

4.14 Filling in flux

4.15 Starting a warm-up cycle

NOTICE

Target group: standard operator

The procedure described is a regular task that can be carried out by any trained operator.

The LDU provides a warming function. This helps to influence the viscosity of the flux before it is

used. During this warm-up cycle the LDU performs a number of squeegee processes which can be

set. This moves the flux and "warms" it up.

The number of squeegee processes is set in the line software: 4.1.12 "Setting the warm-up cycles

and the squeegee speed" [}52].

For information on the viscosity of a flux, see chapter 3.3.4 "Viscosity and thixotropy" [}37].

► In the station software, select the Setup

view(1) and then the Locations area(2).

► Select the Table(3) on which the LDU is

set up.

► Select the icon of the LDU(1).

► Click on the Settings... button (2).

► Select the Dipping area tab (1).

► Click on the Start warm-up cycle but-

ton(2)

The LDU performs the set number of squeegee

processes.

► Click on the Start warm-up cycle but-

ton(2)

again to stop the process.

After finishing the warm-up cycle, the production can be started.

4.16 Monitoring production

NOTICE

Target group: standard operator

The procedure described is a regular task that can be carried out by any trained operator.

During production, the correct functioning of the LDU should be checked regularly. For this pur-

pose, perform the following steps:

► Check the level of flux in the flux tank and fill in more flux if necessary.

► Check the required flux layer height in the cavity of the dipping plate and prepare the flux

again if necessary (see chapter 4.17

"Refreshing the dipping medium" [}78]).

► Check the downholder for contaminants and clean it if necessary.

► Check the application unit for any leakage and remove any flux which leaks out.

► Check whether there are components or other contaminants on the application unit, in the

cavity or in the flux or flux tank. Stop the production process if necessary and remove these

contaminants with a pair of tweezers or clean the complete LDU application unit (see chapter

"Cleaning" [}81]).

CAUTION

Components or other contaminants on or in the application unit

can cause considerable damage to the LDU!

► Remove any components or contaminants immediately from the LDU.

► Use a suitable measuring device to check occasionally the required flux layer height in the

cavity in the dipping plate (see chapter 4.5

"Checking the layer thickness" [}62]).

Cleaning of the LDU after use

Do not leave the LDU standing for longer periods with the flux inside. The flux could dry out and

clog up the LDU mechanics. There is then a risk that the mechanics are damaged when you restart

the machine.

► Clean the LDU after each shift.

► Clean the LDU at least once a day.

► Clean the LDU when it is taken out of the production process.

4.17 Refreshing the dipping medium

NOTICE

Target group: standard operator

The procedure described is a regular task that can be carried out by any trained operator.

With the Refresh dipping medium function you can perform a set number of squeegee move-

ments to refresh the flux in the cavity.
