For years all our R&D for high temp applications (automotive underhood electronics) has shown that Pb-free, at our max temps, doesn't have the reliability of SnPb. Fortunately, for us, EoLV (End of Life Vehicle) legislation in Europe was enacted bef

Hi, On a semi related front, part of our company is a distributor (I'm not going to say who, coz that would be sneaky advertising), and on all components shipped we've added the follwing to the label: ROHS Compliancy Status(Lead free & plastics etc

Don't make that assumption. Once we had concerns about PCB's not matching what was ordered. I said "if we got HASL instead of ENIG, how do we know we got lead-free?" I mean if one thing got mixed up in translation, maybe two did. So we put a bare P

If they are reflowing pbfree balls to bare PCB pads they are getting that component very hot tpo melt the balls and get them to wet to the pads! I would not recommend this process at all for hightemp solder balls, for 63/37 this process is fine. As

Thank you for reply, Stephen. No, As I wrote it was leaded process. I heard that it is possible with lead free solder at higher temps an dwell time. At NPL Defect Database I've find this case wich looks exactly the same: http://defectsdatabase.npl.co

Indium got back to me with the attached PDF. I always assumed, that in order to avoid thermal shock, there could not be any more than 80 degrees C difference between the solder pot and the pre-heated board. However, it would seem that any thing le

Your failure rate should be as good or better than any other leaded part on your board. Have you done a reflow profile on this board. We typically sacrifice a board and drill a hole from the bottom and then imbed a probe under the part to get the tem

I have a problem we change a product from leaded to lead free, I was not involve in the selection of the new reed switch, but now we are having problems with the hermeticity in the switch,this occurs after is overmould and put to a 6 cycles in the th

237C max is on the low end for SAC305, especially if you have heavy leaded components. I always went with 245C and above depending on the board design. I noticed the electrolytic caps. You need to check max temp with the manufacture on those. When I
