we are turning on the printer, suddenly the printer is off after checking there is solderball on pad capacitor component 0603 our question is what can a solderball stuck on one pad can when melting and causing shortsolder (being connected with other

Brian, 96.5Sn/3.5Ag is eutectic at 221 C 95Sn/5Ag has a melting range of 221 - 240 C Hope that helps you out...

What is the liquidous temp for: 95Sn/5Ag and 96.5Sn/3.5Ag thanks in advance

Hi Brian, Here is the web address for Indium. If you go to the "technical papers" and then to "specialty solders and alloys" they have a really great chart that has all the alloy specs. Well worth printing. ........Jeff Sanchez

Hello, Dr. Ning-Cheng Lee The melting point of solder PB-Free its to higher do you now the lower temperature of an PB-Free and its constitution. Its true if the solder paste have in its constitution a Bismut component the melting point its lower?

Dear All Does anyone know about the low melting point solder paste which should be Copper Base? Usually the Copper base solder has 227'C of melting point.

Hi Mark thanks and useful. However, I couldn't find the Copper base solder paste which melting point is lower than 210'C.

Jacki, Lead-free Cu based alloys with melting point below 210C don’t exist.

Dr. Lee: Taking a tangent on your response ... When talking about alternate solders. Bismuth forms an alloy with lead with a melting point of 93�C. Are there special conditions that cause this alloy to form? Or does the alloy form commonly when

An example of very low melting point Pb-free solder is 58Bi/42Sn. Different versions of this alloys have been tried, such as doping with various additives, in order to enhance the reliability further. Yes, Bi is one element which promises low mp for
