over a cellphone board,there are many small components,like chips,metallic ics and a chip like a rectangular component with metalic tops and green bottons----some of these metallic components have inside them a tiny circuitry-----some have printed in its top, code numbers---and in its bottons numbers------most of them have nothing printed on them-------here goes 2 of the chips numbers: the first-----
8518a
a-do4a
ALPS

the second vd2sa2 the top--------------and the botton = t2

in the circuitry there are small metallic dots(pd ag al?) gold collor dots and tiny black chips
does anyone knows anything about these components?

Here is an ALPS switch I know that they contain a loose round gold plated piece of metal. Like the gold plating you see under where the buttons on a cell phone would be.

Hi Everyone,
Can anyone tell me what these are. The boards are cell phone boards.
Thanks for the help,
Scott

Yep they have holes in them. I should have posted a side view.
Thank you for the reply.

I am paying $12/lb for cell phone boards right now for members of the GRF and I pay for shipping with pre-paid Fed Ex shipping labels.
