Hi all I just got feedback from my customer about "White residue problem" around solder joints with manaul soldered connector at customer site and included the failure analysis report that there is residues of Cl,S,Na . I 'd like to know, the white residue/comtammination come from? and Are they(white residue and Cl,S,Na) rejected under IPC standard?
Thank you and best regard.
