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

Joe: I know this is not the correct forum to post chip "reworking" questions. Reply: Rework questions are as appropriate as the next topic here on SMTnet J: BGA will not reflow at any normal temperature level. I believe these chips may have been gen

I think the main cause of this condition is #3 because both #1 and #2 never change from board to board, these are identical boards with identical BGA revisions. These BGA's (as stated before) are about 3 years old.. I don't believe they are lead free

I am trying to develop a process for building high environmental temperature PCBs (150-225C) specifically for down hole applications. I'm specifying an evaluation board and was thinking about using polyimide PCBs with Sn05Pb92.5Ag2.5 solder. What so

Not much help for what you have manufactured but you could try using a lower melting point solder paste? Sn/Bi/Cu

| Looking at the full convection reflow oven market, I see two segments, high mass heater ovens (i.e. Electrovert Omniflow,...), and low mass heater ovens (i.e. Heller,...) | Did some of you guys did some testing on both types and what were your find
