Bungard Green Coat
Green Coat is a new spray coating for all PCBs that are manually soldered.
1st Step
you preprare your PCB as usual and you remove the etchresist completely.
2nd Step
if you like, you may add immersion tinning to the copper surface (not obligatory)
3rd Step
you spray coat the PCB with a thin layer of Green coat.
4th Step
you wait for 5 minutes to let the surface dry.
5th Step
do your normal hand soldering through the green coating. You will recognize, that soldering is very easy. GREEN COAT is containing flux and improves solderability!
6th Step
Cure green coat in an oven at 80°C for one hour or for 2 days at normal room temperature.
The coating will now protect your PCB.
Greencoat is available as 150ml and 300ml spray bottle.
ATTENTION: After curing GREEN COAT is not good solderable anymore.
