SMD - General characteristics
CTC21, CTC21E, CTC3, CTC4, CTC3E, CTC4 RSE, CTC23, CTC42, CTC42E, SMT47:
vapour phase or infrared (see temperature profiles below) and soldering iron.
CTC3, CTC4, CTC3E, CTC4 RSE:
Double-Wave-Soldering (see temperature profiles below)
VAPOR PHASE SOLDERING, BATCH SYSTEM WITH PREHEATING:
ATTENTION
For models CTC21, CTC21E, CTC23, CTC42 and CTC42E, SMT47 for which the
nominal voltage (U
R
) is > = 40 volts; due to their substantial volume and the
thermo-mechanical constraints brought about during the soldering of circuits
by the method “infrared forced convection”, we advise as far as it is possible by
the design of the board to make this soldering manually using a soldering iron.
Numerous experiments demonstrate that this solution although difficult to
control gives very good results compared with the above-mentioned automated
method.
For soldering ovens using “infrared forced convection”, their mode of operation
depends on the coefficient of absorption of the surface of the material and the
thermal mass of the various components subjected to the infrared radiation.
The temperature of the various components under these conditions is not
easily managed or controlled during the passage through the oven. For some
components, temperatures within the components were found to be much
more than 15°C higher than the external temperatures.
VAPOR PHASE SOLDERING, IN-LINE SYSTEM WITH PREHEATING:
The parameters which affect the temperature of components are:
• Time and power
• Mass of the component
• Size of the component
• Dimension of the circuit
• Coefficient of absorption of the surfaces
• Density of components
• Wavelength of radiation of the source
• Relation between energy of radiation and energy of convection
The standard profile of this process is given on the previous page and comes
from the CECC standard 00802.
INFRARED SOLDERING:
A period of pre-heating is necessary to allow the evacuation of solvents
contained in solder flux before starting the flux “wetting”.
ADVICE
•
•
•
DOUBLE-WAVE-SOLDERING:
Preheat the board (to eliminate the tracks of humidity) before the application
of the solder flux. 4 hours minimum in +70 °C.
In the case of a double-sided board, not to clean after the first passage. It
could result in a higher level of humidity which could affect the quality of the
soldering during the second passage.
A minimum solder joint is preferable. The solder does not have to run up too
high up the connections.
Good solder joints are realised with connections having a good solderability
(check the angle of wetting).
The mechanical adhesion of the component on the board is best assured
when the connecting pad is directly in contact with the board.
