Anyone using Entek OM final finish to replace HASL & ENIG?

Thanks! I was beginning to think no one else ever uses this finish, or worse yet, they never profile.

Hey Board House, You forgot to mention Pb-free HASL, how come? I ask because where I work we're running Pb-free HASL as our "preferred" board finish.

It is Solder Mask on Bare copper, The land finish is HASL as per MIL-PRF-55110G which accepts trace of HASL as acceptable. Wetting is acceptable. regards, R.Saravanan

I don't believe there should be any issues with the HASL finish. The issue is how long on the shelf and is a bake out required to remove moisture from PCB, as in any FR4 PCB's that may have had time to absorb moisture.

We recommend a ramp soak spike profile for HASL finish, so everything gets nicely heated during reflow, we soak around 180C and peak at 245- 250C and don't have any issues as long as the levelling isn't too peaky.

We use ENIG whenever possible, to the extent that we will try to talk customers out of Pb-free HASL until our keyboard punching fingers bleed. It's much more solderable than HASL and it's flat.

Has anyone had experiences of ICT test fixtures actually damaging the PCB boards - typically when they have moved away from HASL finish to OSP. I would also like to hear more about any specific issues seen at ICT for non HASL pcb finishes thanks -
