The buyers in our company like to change the PCB finishing because of reducing costs. The proposed change is going from Ni/Au to HASL lead free, I know that in the beginning of the lead free period there where a lot of problems to use the HASL especi

I'm not on the production floor on a daily basis like the other guys here but here's my 2 cents: With a Ni/Au plating the inter-metallic that needs to be formed is Ni/Sn. Ni/Sn inter-metallic requires higher peak assembly temperature and a longer dwe

Hello, We replated the boards with new Ni and Au and the soldering flow is excellent. There is 100% covarage of the pad even for reduced appertures. Mark

Hi, we do Sn plated I/O pinning insertion into Ni/Au thru' holes. no problems here so far, as we cater for the "interference" (fit-allowances) of the I/O pin into the thru' diameter, via improved PCB thru' hole designs. before this cater/considerati

Which is the best surface finish to be used on non- solder mask defined pads in terms of cost and reliability? What are the advantages and disadvantages of the various surface finishes such as Ni/Au , Cu OSP , Ni /Pd and HASL.

Emmanuel: Take Jax's word. NiAu (ENIG) primary (some would say only) redeeming characteristic is its flatness that you mentioned, but that flatness appeals to folk placing fine pitch devices, rather than BGA. Good luck. Dave F

Thanks a lot Dave. I think I will stay away from OSP. I just thought that it could be a cheaper solution than NiAU for fine pitch. And I don�t trust the silver coating types. Brian

I am interested in the opinions of those who have done experiements or have experience with HASL, OSP's, Palladium, Ni/Au , and White Tin PWB plating. Based on your experience please give me the pro's and con's of using these plating options. Thank
