Thanks Mark and Dave. It sounds like our board design and problem areas are similar to yours, Mark. We talked with our customer about the grid pattern but I'm not sure where we are at with that. In reference to the Tg/Td thread, the material is a

It would make sence for Swatch I guess, they probably dont use any component over 0,6 pitch. Didnt swatch just say they would stop production if they didnt get the exemption? Thats probably the main reason they got it, otherwise all this RoHS crap

I want to say one more thing on this; many times RoHS is compared to the CFC elimination. But there is a huge difference between the two for following reasons: In late 80�s scientific evidence became available that CFC�s contributed greatly to the o

Is anyone using standard FR-4 material for ROHS? All I have ever seen to indicate the need to go to a high tg/td board is that the material may fail after repeted rework. I have a customer that is trying to use IS-410 and it is causing electrical pro

How do you measure how pregnant a woman is? A component is ROHS compliant or it is not. If a component is not compliant and is put into an otherwise compliant assembly then that assembly is no longer compliant. I doubt anyone on here does any calcula

If I need a lawyer I'll look you up. To get into that kind of detail you will have to look at the legislation itself in question. And I"m sure if there were any such loophole it would be plugged by now. But we had a customer that found something l

One of the best sites for RoHS info I have ever found is http://www.pb-free.info/ The details about the separate-able-ness of a part, or the concentrations of the individual substances are not stated in the actual directive, they are stated in the

Never though an American would know about our little country beeing without a gouvernement for half a year. In Belgium, this is how law making goes: 1. First think of a rediculous proposistion. 2. Make it a law and execute it 3. Find out that is red

For those of you who've completely switched to Pb-Free or who're running in a mixed environment, are you also buying or specifying the "RoHS PCBs" - the ones with * Greater Tg (glass transition temperature) * Thru-holes with limited drill hits and

Davef, thnx for your reply. Sorry, forgot to clarify "our normal soldering process". We use standard Sn/Pb & SAC305 for our non RoHS & RoHS requirements. We only have a "No Clean" process, no aqueous flux is used. Hence our flux will be mild. As susp
