It's probably internal to the part to stop it falling apart when you

solder it.



So no, nothing wrong with what they're doing probably just your

understanding of what is going on.



If the part with lead is internal to their part then it won't affect

your wave.



Get them to be more specific over the make up of the part.

Chris

Subject: [LF] RoHS exemptions containing lead



OK, here is today's $64 question.

 

We have a vendor stating his parts are as follows;

 

(RoHS Compliant, with exemptions: 



The supplied product does contain relevant substance exempt under the

following criteria:



Lead (Pb) in high melting temperature type solders (i.e.) tin-lead

solder alloys containing more than 85% lead.)



If we have some of these parts and solder them into circuit boards in

our lead-free wave solder system, aren't we going to contaminate our

solder pot with lead?



Are these vendors off base by supplying components with "high temp"

solder to get around the RoHS requirements?  In my opinion they are

taking the easy way out for them with no concern for their customers.

 

Has anybody else encountered this and what was your solution?  I feel a

vendor change coming on.

 

Phil
