Mr. Lee, Although most of the lead free alloy used for solder paste and wave soldering have been identified, a suitable alloy used for leaded Ic packages (like QFP, PLCC..etc) have not been identified yet. Do you have any suggestion on this lead-f

Known: During PCB maufacting nickel alloys are used for corrosion resistance during gold immersion process. A nickel alloy with a high phosphorus concentration will cause a weak connection interface. Question: Is the concentration of phosphorus in ni

Sn/Cu/Ni is introducted to me in wavesoldering lead free process. Around in our industry, we have a plenty of info. about SAC but not on this alloy. The distributor showed me some information about this alloy including less dross, more shiny /smoot

Not sure what a higher Tg laminate will accomplish. Can't hurt though. Remember, when soldering to Alloy 42, the surface is 42% nickel. So, you need to raise the reflow temperature some 15 to 20*C over what is needed for copper. Also, sometimes All

Hi, I think that the time depends on the type of stainless steel, temperature and solder alloy. For example, one of our machines is delivered with 316 stainless pot and alloy SnNi. It worked six months (120days*16hours = 1920hours) and aft

Hi all, Does anybody have any comments on the lead-free alloy SN100C from AIM solder? I am in the process of selecting the "right alloy" for our lead-free wave solder machine. We manufacture A/V equipment. I appreciate your feedback as usual. Hir

Interesting document. They are using a very high tin content alloy 99.5%SN, and suggest they can cange to a 90/10 PbSn alloy that will still mean they meet the RoHS Directive as alloys over 85% lead are exempt within RoHS. so if they used this they c

Hi below is a link to a database set up that list the properties of all SAC alloys, worth reading. http://www.europeanleadfree.net/POOLED/DOCUMENTS/a178886/ELFNET_COST531_Solder_Alloy_Properties_Database_v1.pdf its from http://www.europeanleadfree.

Hello Could somebody inform us about real consumption of lead free solder alloy SN100C on your wave solder process. We do not use some antiaxidant and had had alloy consumption about 1 kg per hour. What is your experiance? All sugestion will be well

We are in the process of qualifying our SMT lines for the High Melting Point Solder with alloy composition of 93.5 Pb 5 Sn 1.5 Ag.If any one has already an experience with this alloy,kindly do give ur inputs on the process of profiling . The reflow d
