> Subject:      Carrier Materials
>
> We are currently manufacturing a new production line which
> uses carriers which traverse around a moving line for
> assembly prior to going over a wave soldering machine.
>
> The problem is the carriers are made of an FR4 type material
> but what material can be used as stops on the underside of
> the carriers to stop wear?  The tool maker has tried metal
> stops (steel) but these pick up solder.  Even stainless steel
> causes problems because a film of solder picks up on stop and
> causes problems when it falls off on the line.
