Hi, That's good news, and we did outs with SN100C as well on Wed, however we are still working hard on getting a good profile. We have some large BNC connectors, and they are hard to profile. We also have wave palettes, and these might be too thick

If the only difference is the layer count, check the profile as stated above. If you dont have a profiler you can probably get the local Kic or Mole rep to do a demo on that board. I believe I was the one who stated in an old post that prying the lea

nice to hear from you..my company is an ems.so need a more flexible reflow.. we have 3 lines and soon to install another line for leadfree ideally..so.. its getting a new one hopefully..a seven zone actually i think might do the job... for the wave i

Chunks, I used to work in power electronics, and we had this design engineer who used to "blow moisture" on the high-impedance circuit and test for cleanliness. We were water washing in a OA-Water Soluble environment. He was convinced that there w

Hi Grant, just my opinion, I think the concern could be related to the extra temperature the BGAs have been exposed during the Lead Free Reflow Temperature. So you need to check ( data sheet) what is the max temperature and how long the Pb/BGA can w

Hi, Reliability was what I was worried about. We have not shipped these yet, as we are not sure about reliability. We can ship them in regions outside of the EU anytime so we are ok on that, and because of supply chain delays, we are already shippi

Hi, That's a really interesting article, however one thing I am a little confused on. They seem to say a Pb-Pb solder joint is almost as bad as a Pb-lead free joint in their results. Are they saying the testing which looks like it cycles up to 125 D

We all know those academic 'reliability studies' are very focused and only give a snapshot of real life. The real reliability studies of leadfree are starting as we scramble to meet our numbers. We have no idea about your customers' expectations ab

I got some info about it last year. I could not justify ROI since this machine was way too expensive (same thing with Vitronics Selective machines). You need to see if this machine will increase your throughput or not depending on your products. Al
