We had actually delivered 16pcs of PCB contact boards = 16pcs to you on May 26, 2016. These 16pcs used the high temp soldering 250C with new flux and we have already tested for longer lifetime. However, please confirm if you will need the additional 8pcs then Akapap will support you tomorrow.
Thanks.
Request PCB contactor board = 8 ea, then used high temp soldering 250 with old flux (previous flux makes PCB soldering cracked) for evaluation.
