What temperature spec are people using in the industry to make sure an electronic component is SMT reflow compatible ? Ex. I have some parts that I want to possibly process as Pin in Paste but am not sure what temperature ratings the plastic will m

The lowest peak temp. I've had the pleasure of working with is 240°C +/- 5°C. I can't imagine a manufacturer going much below that and still saying it's lead-free compatible. It would be interesting to know just how much TAL plays into the affect

NO-LEAD COMPONENTS WITH LEAD SOLDER ISSUE: We agree with Russ. We've dicussed this several times on SMTnet. For instance, look here http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=25394 LEAD COMPONENTS WITH NO-LEAD SOLDER ISSUE: We disa

A while back we checked out all our manufacturing equipment for lead free capability, we thought our soldering irons would all be fine as they can reach temperatures well in excess of lead free alloy melting points. Last week i was speaking to someo

Apoligies Steve if I did not explain myself clearly. We have made the same design using the same RoHs compliant components (which I am assured by the suppliers are process temperature capable) with both lead and lead free solder. Without wishing to

Hello, I want to ask on suitable temperature profile for PCBs with ENIG final surface finish. I know that it is complex question with many unknowns. When the PCB will be standard 1,5 mm 35/35 Cu and the amount of components will have any influence o

Yes, appropriate storage & component handling proceedures should be followed depending on the MSL (Moisture Sensitivity Level) class of the component. Some component suppliers are now marking the MSL class on the label, along with PBT (Peak Body

I agree with Chris. Not all but SOME components definitely had to change to be able to withstand higher heat. I would watch out for some plastic connectors, possibly some active components, and definitely many electrolytic caps. Older stock compone

Could you advise what is the min and max peak temperature for this process. Presently, my leaded peak temperature at the range of 215 - 225 deg.C And how do I know that the solderability is at optimal. Appreciate your help......

With the added temperature peak associated to Lead free reflow is anyone seeing or concerned about the increased vapor pressure that may result from moisture entrapment in moisture sensitive components?
