Safety Instructions; Description; Assembly Wbh S; Operation - Weller WBH Operating Instructions Manual

Thank you for placing your trust in our company by purcha-
sing the Weller PCB holder WBH / WBH S. Production was
based on stringent quality requirements which guarantee the
perfect operation of the device.
1. Caution!
Please read these Operating Instructions and the attached
safety information carefully prior to initial operation. Failure
to observe the safety regulations results in a risk to life and
limb.
The manufacturer shall not be liable for damage resulting
from misuse of the machine or unauthorised alterations.

2. Description

The WBH PCB Holder was designed as the basic device for
supporting PCBs. The extended version WBH S includes an
additional tripod for the clip on the hot air hand piece WHA
3000. Furthermore, the PCB holder can also be provided with
a bottom heater (WHP 3000 hot plate). The combined com-
ponents create a professional repair system for PCBs with
high-pole fine pitch components.
Optional devices/accessories
WHA 3000P Hot Air Station
WHA 3000V Hot Air Station for compressed air or nitro-
gen operation.
WHP 3000 Infrared Hot Plate

3. Assembly WBH S

1. Install stand column to WBH using mounting bolts (11).
2. Clip in hot air hand piece (4) into holder (5) and secure
using O-ring.
3. Remove cover plate (12) and insert supply hose
and then reinsert cover plate (12) into the groove.
4. When using the WHA 3000 controllers: insert the enabling
connector into the socket for the switchgear
For operation with Hot Plate WHP 3000
5. Slide the bottom heater (Hot Plate WHP 3000) from the
front under the PCB holder, or place the PCB holder over
the hot plate. Make electrical connections in accordance
with the Operating Instructions for WHP 3000,
WHA 3000P / WHA 3000V.

4. Operation

Once the clamping screws (10) have been released, the arms
of the PCB holder can be moved and the PCB to be repaired
can be inserted. By pushing both arms in x-direction and the
PCB on the holder in y-direction, the component to be repai-
red is aligned with the hot air nozzle and / or bottom heater.
Both arms are then secured again with the clamping screws
(10). The use of the PCB stop (9) allows PCBs to be replaced
in the exact position.
The swivel lever (6) is used to lower and raise the soldering
head. In lower position, the depth stop of the soldering head
must be set with the knurled screw (7). When the soldering
head (6) is lowered, the hot air nozzle (3) must only make
light contact with the component and must not exert exces-
sive pressure on the PCB.
The soldering process is usually started with the hot air
nozzle raised to preheat the system.
A universal PCB repair of SM components requires effecting
preheating of the PCB from below and targeted heating of the
components to be repaired from above up to reflow tempe-
rature, in conjunction with a reliable process control system.
With the WHP 3000 hot plate, the temperature controlled, 2-
zone, infrared bottom heating ensures fast heating and
homogenous temperatures. The hot air top heater
WHA 3000P / WHA 3000V with digital control electronics for
temperature monitoring and air-volume control guarantees a
finely metered thermal energy supply to the components.
