2.1 Safety Information

 Always place the Reflow Nozzles in the original holder
 Remove all inflammable objects from the proximity of the hot

soldering tool.
 Use suitable protective clothing to prevent the risk of burns

associated with molten solder.

 Never work on electrically live circuits or components.
 Always wear eye protection when working with soldering and

desoldering applications.

3 Description of the WRK

The Weller WRK Removal Kit optimizes the rework process and
enables SMT components to be removed precisely and without being
damaged.

The removal procedure can be optimized for each component size
between .120" and 1.181", (3 mm and 30 mm) with the aid of the
different reflow nozzles.

The reflow nozzles are suitable for the use of the HAP 1 and

HAP 200 Hot Air tools.

Suitable reflow nozzles for HAP 1 and HAP 200

Note

unit.

1. Carefully unpack the WRK.

2. Assemble reflow nozzles (2, 3), tripod (4) and pick-up tool (6) in
holder (1).

3. Switch off the control unit.

4. Connect the hot-air pencil (HAP) with air hose to the "Air“ outlet of
the control unit and insert with the attachment plug in the correct
connection socket of the repair station. Lock by turning clockwise
slightly (connect HAP 1 with adapter only).

5. Connect vacuum pick-up (6) with vacuum hose to the vacuum
pick-up ports of the control unit.

6. Attach a suitable reflow nozzle or tripod to the vacuum pick-up
(see Sections 5.1 and 5.2).

It is possible to use large reflow nozzles, small reflow nozzles with
tripod or the tripod on its own to lift off small components with the
vacuum pick-up tool.

4.1 Mounting the Reflow Nozzle

1. Check the .400 ", (10 mm) diameter vacuum pick-up tool to ensure
the components (clamping sleeve (5), marker ring (7) and vacuum
cup with heat shield (10)) are correctly installed.

2. Assemble nozzles directly to vacuum pick-up tool (6) using the
clamping sleeve (5).

Note The reflow nozzles are not assembled directly to the .180 ", (4.5

mm) vacuum pick-up tool. Ensure the tripod and the.180 ", (4.5 mm)
diameter vacuum pick-up tool are correctly positioned in the nozzle
and on the component.

4.2 Mounting the tripod

1. Check the .180 ", (4.5 mm) diameter vacuum pick-up tool to
ensure the components (clamping sleeve (5), marker ring (7) and
vacuum cup with heat shield (10)) are correctly assembled.

2. Screw tripod (4) to the vacuum pick-up tool (6) using the clamping
sleeve (5).

You can use the .180 ", (4.5 mm) diameter vacuum pick-up tool
mounted in this way with a Large reflow nozzle (A1) or with Small a
reflow nozzle (B1). When working without a reflow nozzle, you can
also use a .400 " (10 mm) diameter vacuum pick-up tool.

5 Using the WRK

WRK operation during the component removal procedure is divided
into 3 steps:

1. Positioning the Vacuum Pick-up tool

2. Preparing for Component Pick-up

3. Reflow and Removal of the component

5.1 Positioning the Pick-up

A 1 B 1

ENFRITESPTNLSVDKFIGRTRCZPLHUSKSLEELVLT

The component to be reworked must be at least .08 " , (2 mm)
smaller than the diameter of the reflow nozzle used, otherwise the
component may be damaged.

Z Carefully position the large reflow nozzle (A1) or tripod with small

reflow nozzle (B1) with the vacuum pick-up tool over the
component and center the component within the nozzle.

Note Pictures are for illustration use only. Vacuum hose must be

connected and activated for the vacuum pick-up tool to operate.

1. Carefully position the vacuum pick-up tool with mounted reflow
nozzle, (A2) or with the tripod, (B2) over the component.

2. Carefully press the vacuum pick-up tool down .120- .400 ", (3-5
mm) over the component (1) without damaging the component.

3. Switch on the vacuum on the control unit and subject the
component to suction.

4. Slide the marker ring in this position downwards (2).

The marker ring indicates whether the component subjected to
suction is raised (rubber = at top) or not raised (rubber = at
bottom).

5.3 Reflow and Removal of the Component

WRK 7-9

1. Position the vacuum pick-up tool over the componet (see 5.1) and
prepare desoldering (see 5.2).

2. Feed the hot-air tool from the side through the designated nozzle
opening up to the component and actuate the hot air tool until the
component is reflowed and raised by the vacuum pick-up tool (see

5.3).

The marker ring is now in the upper position.

3. Remove the hot-air tool and switch off.

4. Position the vacuum pick-up tool together with the nozzle and the
removed component on a heat resistant surface.

5. Carefully press the vacuum pick-up tool downwards and switch off
the vacuum. Wait several seconds for the component to release
before moving the tool

Note You can also work without a reflow nozzle, e.g. in the case of

components larger than 1.180 ", (30 mm).
