We are using SAC305 for reflow and SN100C for our selective solder.

SAC is a lead free solder alloy. At one time, Nippon Micrometal Corp. (NMC) [158-1, Sayamagahara, Iruma, 358-0032, Japan; +81.4.2934.6101 F+81.4.2934.5454 nmc-net.co.jp] called some of its alloys: LF35, LF45(SAC305), LF38(SAC105) and LF31(SAC405).

Hi, does anyone have any experience with common wave soldering defects using SAC305 alloy?.....i am finding a lot of what seem to be shrinkage cracks on the bottom side surface of the soldered components.....there is also a lot of directional cooling

Sheldon, Try using SN100C wire solder. It seems to extend the life of the tips plus solder joints look much better. We use both, clean and No-clean. We had the same problem while using SAC305... Thanks, George

I can't answer for wave, but we tried some Sn100 paste for reflow, and couldn't get it to work worth a darn. I then got some SAC305, and was relieved to see it work almost as well as SnPb at its best! Much better wetting and flowing to the various

We have using SAC305 type solder paste for lead free process. One sample paste received of SN100C.After reflow SN100C type paste joint looks brighter and good compare to SAC305. Please help me which paste is good for smt process?

Good day all, I wanted to get a quick poll from the folks running SAC305 in their selective soldering equipment. How are final results? How repeatable is the process, any machine related failures? pumps? nozzles? etc... I am just looking to get a

Kester offers Tin-Copper AND Tin-Copper-Nickel. The Kester K100 alloy is a Tin-Copper-Nickel material that is very similar to SN100C. Straight Tin-Copper isn't tremendously popular but can be used in low-cost, consumer-electronics applications wher

Aj is right, utilize the homeplate aperture, this reduces the amount of paste actually underneath the component, Pb frees exhibit this mid ship more often than the lead, I think,it is mostly because of thre transition to noclean form water solubles
