Hi Paul, Can't find any info on Cobalt 995,but we do have experience of 99/0.7/0.3 +0.02% Cobalt wire - flows better than any leadfree wire we've come across & the cobalt is supposed to improve tip life. Bit smokey though, but with extraction that'

Hi Grant, You definitely have a pre-heat problem and not a flux problem. Pallets together with the BNC connectors put a large thermal demand on your pre-heating. 3 zones would be a good investment even with leaded solder due to the high thermal dema

Again, the verdict is mixed here as well, but from the seminars, white papers, etc. the consensus seems to be that Pb BGA's are not compatible in a Pb-Free RoHS Process...but... Pb-Free SAC BGA's are compatible in a Sn-Pb process as long as your pro

Nathan, Please don't listen to the Guru. His experience in this industry is as non-existent as his magic mine. Guru, please go somewhere else. This forum is for technical advice, not sales. For those of us in reality, it is usually best to sti

Hi CP, I used to work for a flex circuit manufacturer. I am at a CM now and am we have started building RoHS production status assemblies. I personally think flex circuits will have a difficult time with the required temps for RoHS. I spoke to someo

I'm looking for some information on soldering irons being used in my no-lead process. Specifically, my floor seem to be burning out tips at an alarming rate, when soldering lead-free assemblies. Today, I had one woman burn out a brand new tip in 4

*We've tried the WSP80s for leadfree, also SAC. Problem with these was when they are not being used, they keep their temp and oxidate like hell. Second problem is as Russ states, the sensor is not in the tip, therefore to get the same heat in the t

Anyone have any experience with Displacement Soldering? We just came across a benchtop displacement soldering system, and I'm wondering how effective it might be for me. We're currently looking at a "best" solution for us right now for lead-free

To make it even more compicated, you have CTE before Tg and after Tg, altough the after Tg is way more important, because the expantion ratio will be much bigger, a pcb supplier will usually give the before Tg value. To come back to the delamination

SMTNetters, I have a product coming down the pipeline that we'd like to make pure double sided reflow, it'll be RoHS product, and the hope is... we'll be able to solder the thru-hole stuff by screen printing solder paste and reflow soldering. Anybo
