6.3 Maintain the Print Enviroment
Correct Temperature Within Printer
The temperature inside the printer should be stable at the material manufacturer’s recommended
working temperature (normally around 22°C – 24°C for solder paste). Printer covers should be left
closed whenever possible to avoid fluctuations.
Correct Humidity Within Printer
The humidity inside the printer should be stable at the material manufactures recommended
working level (normally around 40% – 65% relative humidity). Printer covers should be left closed
whenever possible to avoid fluctuations.
General Factory Environment
Generally speaking, if the environment is comfortable for humans it will be suitable for the print
material. If you feel uncomfortable (too hot, too cold, too dry) then it is likely that the print
performance of the material will be compromised The factory should have a clean, stable
atmosphere. Ideally it should be air-conditioned with temperature and humidity stable throughout
the day and throughout the year.
Best Working Practices
●
Keep printer covers closed whenever possible to avoid environmental fluctuations
●
Monitor internal temperatures regularly throughout the day
●
Use covers over conveyors to prevent airborne contamination
●
Locate the printer in a clean area away from open windows, direct sunlight, heat sources,
draughts, sources of vibration, etc.
●
Isolate an area around the printer to prevent human traffic, trolleys, etc. coming near the
printer
●
Regularly check that the TCM is switched on, set correctly and all cables are connected
Exercise (if a TMC is present)
Using the TCM operator handbook as a guide, adjust the TCM to the mid-point of the
recommended temperature range for the material you are using.
