storage) will blast the plastic case.
Too low heating-up gradients are also not advisable, because they
will cause an elongation of the assembly's dwell time in the reflow
process. By this way the manufacturing cycle times will be elongat-
ed as well as the long-term stress situation of the assembly. During
the cooling down the temperature gradient should be limited, too,
even if a quicker cooling is less critical regarding possible process
errors. The JEDEC IPC 20B requires a minimal gradient of –6K/s
for components.
For the reflow soldering of electronic assemblies temperature gra
-
dients of ± 2,5K/s are generally accepted.
As a basis for your own profile creation several soldering and cur
-
ing profiles are stored on the system. You can load the profiles and
change them according to your requirements or you can start the
production immediately because the profiles are average profiles.
Because of the low number of parameters which must be adjusted,
a quick changing of the soldering profile according to your require
-
ments is possible. With only 9 parameters you can optimise the
soldering profile which contain the nominal temperatures for the
eight heating areas and the conveyor speed.
You can load one of the saved programs and use it as a basis for
the creation of a new program.
