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

Thank you Stephen... I also mistaken it with Immersion Silver.

| Hi, | There has been a lot of disputes in our company | about changing present HASL to another Finishing | which can provide more flatter pad surface in fine | pitch applications. ( perhaps Ni/Au, OSP ) | The target is to reduce solder defects, t

Russ, We also use 'immersion silver' and have not had any impact on our processes. In fact there are a number of benefits i.e very flat pads (as good as electroless nickel/immersion gold but much cheaper and less unfriendly to the environment), good

We are considering the use of Immersion Silver for a PCB surface finish. We currently use Immersion Gold surface finish, which has served us well. However, recent discussions on the cracking of corner joints on large pin count BGA packages, with the

I am going to be using large numbers of silver immersion PCB's for assembly. I am concerned about long term storage ( shelf life )and handling prior to placement/assembly. The recommended 'shelf life' appears to be 6 months but obviously this will

Would you be interested in a chemical free flexible packaging (bag) that extends the useful shelf-life of fabricated pc boards and surface finishes for that year or more? Let me know, and I'll get you all the technical details. Sincerely, Dave S

immersion silver has become my favorite finish for lead free. Seems toi have good shelf life is stored in the silversaver paper. and reflows real well. Russ

Has anyone come across a standard or study (JEDEC, IPC) where it has the recommended shelf life outside of a dry box for immersion silver coated PCB's to prevent oxidation from affecting the soldering process (Both reflow and Wave). I know it will
