What tip do you have to manage this RoHS deal ..?

Maybe go into another line of business. Pest control, beer brewing ...

As in what works, not what should been etc..

Seriously, I think the best approach is to find a large assembly house
that already has plenty of experience with lead-free production.

Seriously, I think the best approach is to find a large assembly house

that already has plenty of experience with lead-free production.

First is to pick a products and company and stick with it. Don't try to use
ten different brands even if seemingly the same formulation. You will get
burned.

Record keeping, that is a rough one. Everyone is struggling with that.

Last, remember that you are dealing with Rohs even in non-Rohs assemblies.
Since the parts themselves may be leadfree, they will no longer reflow
correctly under old processes and profiles. Since you are using lead
temperatures, leadfree leads my not wet properly and cause joint issues. I
think this one here is the biggest short term problem for those still using
lead based solders.

Hello Brian,

lead based solders.

With parts that can be an issue. However, we have always dealt with
leadfree leads. Take wire, for example. That has no lead and solders
just fine with leaded solder. Same for many board-inserted connectors,
sockets, you name it.

Its not so much an issue as it is an oversight to some. You here people
saying parts fall off boards, etc., with leadfree parts. This can be why,
the new reflow profile of new metal combinations. It is MUCH more an issue
with SMT than thru hole, for obvious reasons. Adjustment to your profiles
will correct it.

If only the other ROhs issues were as easy to fix
