Interesting... We had visitors from (maybe out of space) that claims that the fumes!!! from whithin the reflow leadead solder process in an oven can get caught inside the oven during time and later on when we fire up the beast to the lead free temp-p

Do you have an automated line with pick and place equipment that can handle your BGA's? Inspecting the board is a must after profile development. You may send the 1st board to a CEM for X-ray inspection. If you have a consistent process (printin

Guys, We have an issue with a Board we are running at the moment. We have 3 BGAs on the board 1 Leadfree and 2 are not. We are running a Leaded Process and the LF part is not available Leaded. What do we do? I reckon that all we can do is try an

Here are settings for a Vitronics SMR500 oven for Indium Corp. 5.1 No-Clean Pb Free solderpaste, the product profiled was of medium thermal mass: RTS, Temp C 120, 170, 195, 248, 264, conveyor speed was 43cm/min (17"/min.) Peak temps were reached in

Howdy Marc, Check with your flux vendor, they should have a data sheet with what you need. Baring a wave rider or other profiler, I use a laser thermometer (They're cheap.)and It gets me close to where I need to be on our assemblies. I usually chec

I'm based in the UK and need a new thermally protective case for my SlimKIC. We are running lead-free now and I'm concerned about the extra heat damaging my SlimKIC. I've been quoted �525 for a stainless steel Lead-free compatible case (KIC-1001), wh

I got it from McMaster-Carr. http://www.mcmaster.com/ They have just about everything you could ever want, but I don't know about delivery to the UK. I think it cost about $40, or about 30 Euros, or about 20 British pounds. The dollar really isn'

Hi, Thanks, and we are doing that today. After spending the day playing with all the usual things that used to work, we are focusing today on profiling and data to get things right. The only worry I have is did we get a wave that can handle this, a

There are plenty of studies on this subject. If the BGA can handle the extra temperature and they are soldered on a leadfree profile, the general result seems to be a better reliability than Pb :) Just out of the top of my head, there was a link to

Hi, In our setup what we usually avoid is to use RoHS BGA on Pb process. But we use sometimes Pb transistor(4~6pins) on RoHS process, no BGA yet have been reported. Its really difficult to say about reability unless you start running some functional
