Jerry,
We often use slip sheets when we fab and ship pcb's with
carbon ink, gold, silver, or immersion tin.
We use a sulfur and lint free paper, not sure who the supplier
is, but it's local to the metroplex area I'm sure.
We only do this for the boards with finishes
identified above, as a means of prevent handling, packaging, shipping damage. Of
course the boards are sealed, sometimes with, sometimes without desiccant,
dependant on the cust. requirements.
We typically don't do this for common boards (i.e. SMOBC) due
to the durability of those coatings.

Hello, TN!
Is it a good practice to put
slips of paper between stacked bare boards
before shipping product in sealed
poly bags?
In my experience, this is not commonly done.
Assuming
it is, what types of paper are acceptable, and what types are not?
How long
might it take to affect the activity of HASL metal finishes
(i.e.
solderability) on new
product?
