. This would be related to percentage flux to metal ratio content of the paste rheology. As for the solder paste not reflowing and appearing as a solder ball grain structure on the surface of the solder paste, this is due lack of enough applied heat, which will prevent the solder paste

. Kind of interesting how that problem was solved, or was it solved and we just adapted our acceptable condition and moved on? We still get questions as to the solder ball condition, but it is mostly an educational issue, or new people wanting to reinvent the wheel

/125 °C profiles. The key findings from the thermal cycling tests and subsequent failure analysis are as follows: ▪ X-ray and metallographic inspections showed that the solder paste was effective at producing extreme voiding in many of the ball locations
