Hi every one:
We are currently experiencing some dificulties soldering gold
plated pins, they go on a 1/2 of an inch square pcb w/a cap an a resistor.
we had tried several profiles with no satisfactory results, we are using
kester #Sn63Pb37 solder on a Vitronics 722 20 zone reflow oven as follows:
165-175-250- -260-260-260-260-260-280-400 degrees temp. it may seen to
high but our pcb fixture is thick an pcb bar holders on each side.
The problem is solder looks GRAINNY/COLD any suggestions for a good solder
paste/profile?
regards.
