Look at: http://thor.inemi.org/webdownload/newsroom/Presentations/09.pdf Page 47 shows both alloys to be similar in reliability although its a little troublesome that the particular defects are not isolated as I feel there is a big difference betwee

Hello Bachman. SAC305 is the most common lead-free solder alloy, not only for wave soldering but also selective. Most of our selective customers (especially automotive) are using SAC305. What is more important than the alloy to consider is the flux

Patrick, we were seeing a good amount of Cu-dissolution with both SAC305 and SN100C.. couldn't figure out.. till our good old vendors told us that the Cu thickness in the barrel were not correct... but anyway have started some new work with SAC30

Hi, Have anyone out there been using Asahi products. My knowledge is limited and I only know it from the http://www.asahisolder.com website. Pls feedback or share your view on the Asahi product. If this product worked better than other even if it h

CMiller, Thanks for the valuable info! We are in the midst of lead-free deployment and need to know good alloy choices at both wave and ERSA. I have heard the same things regarding SAC305's price for bar solder, but don't yet know what the process

Hi, So that's really important to have a specific flux for lead free? We are looking at changing to SN100C after reading this thread and other stuff we have found, so can anyone recommend the best no clean flux for that metal? Do you need differen

We have been seeing continued difficulty with solder shorts and/or insufficient barrel fill with our Juki selective solder machine while using SAC305. We want to switch to something in the SN100 series, but we do not know enough to seperate the hype

I've seen many comments in many threads about the positive attributes of SN100C (apparently mostly by salesmen). However, I have a concern for the higher temps that will be encountered when using SN100C (or Sn/Cu) vs. SAC305 (vs. 63/37), specifica

Billy, I have to disagree with you. We inadvertently soldered a Pb BGA with SAC305 paste and then had it micro sectioned and spectrum analyzed. Imagine our surprise when we saw the spectrum analysis showed Pb. The micro sections showed none to ac

I agree with using the homeplate design on chips. Some Pb-free solder paste manufacturers recommend 1:1 apertures. This, in my experience, is not a good idea with any of the SAC305 pastes I've tried. I've been using the same stencil design guideli
