In other words it should mean that Lead Free Soldering Process (this SACs era, and not for istance classic Lead Free Sn/In used since many years ago) is still a "Baby Technology" and so we need experience and feedback from the field before to issue

we are doing many experiment on this problem 1)sn63 pb37 solder paste +normal profile 2)sn62 pb36 ag2 solder paste +normal profile 3)pb free solder paste + pb free profile 4)sn63 pb37 solder paste + pb free profile but still the problem exist so i th

We have a Delta Max (leaded) and a delta wave (lead free) and a soltec Selective solder. The software that runs the selective solder is much different than that of the wave machines. We have fitted our selective with a leaded and lead free pot to han

| Another basic soldering question. I notice that lead-free solders have become required for plumbing applications due to legislation. In a local hardware store, I noticed the existence of lead-free solders (based upon tin-copper I think) with a me

Hi, I just did a seminar on lead free, but don't have any experience myself yet. However the guy running the course said that in all the testing he had done he had not seen any major difference between lead and non lead soldering. He spent quite a b

Being cynical in a RoHS environment is dangerous; it might lead to "lead" dependency. I know it's not easy to accept the fact that the lead-free alloys and board finishes solder as well as my ceramic bathtub. By the way what do you guys distrust the

Yes, the authors do give the caveat that small amount of lead contamination in a SAC/Lead-Free system is tolerated provided the Pb-BGA has sufficiently reflowed. This verbiage is on the bottom of Figure 10. For my own peace-of-mind, I would send yo

I am trying to assess current industry thinking on the question of whether or not lead-free BGAs (SAC or other) can or should be soldered in a tin/lead process. It seems there are differing opinions on this and I'm wondering what some of you are doin

Another tactic. Become friends with all the local solder paste reps, get them to buy you lunch, etc...but the key is...get them to give you free samples. That way you wouldn't have to BUY any paste. As for the original fella, sounds like he's on a

The ISL12020 real time clock comes in a 20 lead DFN, and includes a 32kHz crystal in the package. The terminals of the crystal and oscillator come out to external pads and are highly susceptible to leakage to the neighboring power supply pins. With
