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.

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?

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

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

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

I am looking for the solder wire leaded or lead free which can withstand the solder joint at temperature 450deree Celsius or more after soldering, since i need to form a solder joint at higher temperature area Pls suggest the part number for the sam

There are many alloys of silver solder for higher temperatures mostly used in plumbing There are also alloys which are available in paste form used in the manufacture of hybrids. sarason

The ternary SnPbBi phase does form commonly when Pb and Bi are combined. No special condition required. Presence of this phase jeopardizes the reliability for applications involving temperature near 96C. Using low temperature solders means a lower s
