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?

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

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

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

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

why two high melting temperature metals are getting melt earlier or mean at very low temperature after mixing. Ex :- Tin (sn) - 231 C melting point lead (pb) - 327 C melting point But Sn/Pb - 63/37 melting temperature is 183 C

It's not a silly arguement. I'm guessing you are talking about wavesoldering? Think about holefill, The reason tin will not fully fill difficult holes is the temperature at the top is too low, it is below the melting point. Increase this melting

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.
