Hi,
We are noticing a discoloration of the exposed metal only on this particular part after Reflow soldering.
This is evident in the picture below when comparing the lead color to that of other components.
There is no issue with the solder wetting to the component leads.
We have confirmed that the peak temperature reached during reflow is 224c.
First we want to make sure that the actual component markings on the parts properly correlate to the different part number markings on the bag label and that we do have the correct parts and that they are RoHS.
Second we would like to know if we need to be concerned about the discoloration or can ignore it?
We are using a lead free SAC305 water soluble flux type solder paste.
