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.

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

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

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
