In all fairness no one has the answer for you, non of the lead-free alloys has been long enough in use or have supporting long-term reliability data. No matter what alloy you will use, your company will be at risk, that�s why so many exemptions are a

Hello everyone, at the Institute for Manufacturing Automation and Production Systems of the University of Erlangen (Germany) one focus of our research activities is the use of lead-free solder alloys for electronics production. In different publicat

Inds, This will happen with all lead-free alloys having a tin content above 70%. It takes about 30 sec. for a molten lead-free alloy to totally dissolve a copper pad. The higher the temperature the shorter the time and visa versa. The scary part of

If you do SMT with an SAC alloy, and the Wave Solder with SN100C, what is the impact of accidentally reworking the through hole parts with an SAC alloy wire solder? Or reworking the SAC alloy with an SN100C wire solder? Brian

As a technician that does frequent board level repair / rework some issues have come to mind. I have been an electronics technician for almost 50 years. In that time I have seen the evolution of electronics from point to point wiring using vacuum

I have been using sn100c for over a year now on our wave solder process and I am plenty satisfied so far. The secret for success with this alloy is to have your solder pot near 270 celsius and your dwell time has to be near 4 sec and your temperature

Typical conveyor speeds on leaded alloys and OA flux is 2 FPM. Typical conveyor speeds on lead-free alloys and OS flux is 0.5 FPM. Temperature should be 140 F. Most polypropylene inlines cleaners should not exceed 140 F. -Mike Konrad Aqueous Technol

Plating houses seem to exhibit various results. Unacceptable Ni oxidation levels appear to be related to poor Pd plating processes. Ni oxidation can occur at 3 process stages: 1) prior to the Pd being applied (Ni already oxidized) 2) during the p

HI all, which is the last "though" about the max Pb % allowed/acceptable into a Pb Free Alloy ? For istance inside : - HASL Process Solder Pot Alloy - Wave Solder Pot Alloy ( 400Kg mass average) - Static Wave Solder Pot Alloy - Etc IPC-J-

hi, I am a research student in Electronics manufacturing at RIT. We are planning to assemble boards using lead free solder paste. I was wondering would there be any changes in printing in using lead-free paste"Sn-3.9Ag-0.5Cu". Thedensity of Sn-37Pb
