Good point.
I recall in several of meetings on issues other than soldering, but
concerning PCBs that we were told that all of your processing folks always
had clean hands so that there would never be a transfer issue resulting from
handling at your facility. I remember this being expressed emphatically to
Richmond's senior management over a testing issue when they suggested your
shop should wear gloves to protect test points. It is good to know that "you
all" successfully resolved all of the issues mentioned below without going
to gloves.

George,
There are a few items that you missed and one was the heavy southern
draaawl.
The other is you don't need gloves but it is advisable to only hand the
boards from the card edges.
There are still some bad elements that can transfer to the board and can
cause some soldering difficulties. Most of the issues we found were
hand lotions and pop corn oil.
So no selling pop corn in the vending machines and no Avon or Mary Kay
parties in the cafeteria and you don't need gloves.

You should point out that none of your customers found gloves necessary
with either OSP or immersion silver.

We had over 20 years of experience at the AT&T facility in Richmond with
OSPs. Our customers stored the boards side by side with HASL boards and
experienced no adverse effects. I will also point out that while gloves
give added protection, none of our customers found them necessary.

For immersion silver, we wear gloves when handling them prior to reflow,
and we interleave the silver saver paper and seal them in MBBs to store
them.
We are starting to work with OSP for the first time. What do you
recommend for OSP handling? Gloves is a given, but I am wondering about
storage.
Thanks in advance,
Genny.
