| Dear PCB manufacturers and friends,
I have a query on the Immersion gold gold thickness, can you advise me what is the standard or most common gold thickness you are making if your customer do not have any high gold thickness requirements. Because I noticed that most PCB supplier will advise 1u"-3u" but the actual gold thickness is slightly >1u" only. It have never near to 2u". My customers had advised me that to meet IPC class 2 immersion gold boards gold thickness have to meet minmum 2u". Please advise are you also making mostly 1u"-3u" actual slightly >1u"? is this acceptable and the common practice? Hope to have your favourable advise. Thansk & Best Regards Patricia Lui Xuan Technologies |
