10. If Auto Flux Dip is checked, replace the component nest with the flux dip tray and follow
onscreen instructions. After fluxing is complete, restore flux dip tray and component nest
to their original locations.
11. Slide component nest out of the way, towards the back of the machine so the optics are
unobstructed.
12. The component alignment screen will come up and the heater head will move down
towards the focal position.
13. Adjust the zoom and lighting as needed in order to see the pads on the PCB as well as
the solder balls or leads on the component. Then, using the theta adjustment and X/Y
micrometers, align the component to the PCB.
14. After alignment is complete, click the Alignment Complete button to prepare for heating.
15. If Auto Placement is active, the heater head will lower the component into position over
the board. Otherwise, use the onscreen adjustments to manually lower the heater head
into final position.
16. Align the IR Pyrometer to the desired location using the laser indicator and click the
“Start Heating” button.
17. The IR unit will run the selected temperature profile.
18. Allow the PCB to cool and remove.
If the component installation was successful, it is a good idea to try it once more to check for
consistency and then save it! If the component installation was not successful, examine the situation
and make changes to the profile for another trial run. Temperature graphs from up to 3 previous trial
runs will be available for comparison to current settings. When saving a profile, don’t forget to select the
primary temperature sensor for future reference when repeating the profile in production mode.
Small Components
The IR-3100 is capable of working with very small components, as small as 1mm square.
When working with components ranging from 5mm down to 1mm there are some additional steps
required for accurate placement during installation procedures.
The standard Centering Nest can accommodate components between the sizes of 65mm and
5mm. To work with smaller components, between 1mm and 5mm, the Centering Nest can be replaced
with the optional Microchip Nest, item 6993-0312. An in-program walk through of this process is added
to a profile whenever the “Align Holder” box is checked.
