Hi there, Could someone please tell me diferences and possible benefits that are found when using silver as a pcb finish as opposed to HASL. I've already tried the archives without much luck. ta much, jack

We currently use HASL on all of our boards and I would like to move to something else. I have sampled some boards with Entek OSP and I loved it, the problem is we have plated mounting holes on just about every board we make. Does anyone have inform

We prefer Flat finish. We don't like HASL.

I does depend on the level of technology of the PCB. RoHS-HASL for basic products and Silver Immersion for a flat finish, are my preferred.

Jacqueline, Asuming you mean immersion silver: Advantages - Very flat finish compared to HASL, more easily solderable than bare copper with OSP and more process tolerant than this in our experience, reasonable shelf life, cheaper than immersion gol

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.

John, We regularly wave solder electroless silver finished boards (Alpha Level)with mixed SMD and through hole parts and do not have any problems. We have changed a number on PCB's from HASL to electroless silver, mainly for the benefits at SMD whe

Hi all, For leadfree HASL finish, is there any specification or guidelines for contamination level, esp Cu% to refer? How can we ensure the HASL finish composition is reliable for assembly? Thanks..
