Weller WQB Repair System
The WQB repair system upgrades the Weller product range in the SMD tool sector. A well thought-out design concept combines reliability and maxi-
mum process control with ease of use and technicaly mature detail solutions. Usefull accessories increase the possible uses of these repair work sta-
tions. For the universal circuit board repair of SMD components, it is necessary to preheat the circuit board effectively from below and from above
to precisely heat the components to be repaired to the reflow temperature as well as to reliably control the process. On the WQB 3000 the tempera-
ture regulated 2-Zone infrared bottom heater provides rapid warm-up and homgeneous substrate temperatures. The hot air top heater, with digital
control electronics for temperature monitoring and regulation of the air flow rate, facilitates the finely metered supply of heat to the components. A
temperature sensor placed directly in the hot air nozzle efficiently regulates the top heater and thus provides maximum process control. On the digi-
tal programming unit all process steps can be programmed, saved and if necessary protected against unauthorized use as required. The most impor-
tant process parameters are optionally displayed on the LC display during operation.
The programming unit assists with the determination of temperature profiles and in this way facilitates the definition of optimal soldering process
data in the easiest possible manner. Optionally the WQB 3000 can be controlled with a PC using the software WQB 3000 CONTROL. The program-
ming of comprehensive special functions permits the adaptation of the process to a very wide range of boundary conditions, and thus enables
repairs to be made even on the most difficult assemblies.

Description
BGA/SMT Rework system 2300 W / 230 V,
for component placement with camera
guided positioning system
At the heart of the placing system is the modern Fire Wire
colour camera with fully digital data transfer. The data
transfer from the camera to the PC is made in real time
via the IEEE 1394a interface. The telecentric precision
objective lens produces an image of the component to
be placed free of perspective distortion and has a wide
depth of focus. The included positioning software contains
a component library, from which the component to be placed
is selected. New components can be edited very easily by
the user and added to the library. Using the built-in positioning
frame in the live image from the camera, the circuit board and
the component can be aligned independently of each other
using the X,Y and Theta axis fine adjustment drives.
