I agree with DWL's comments. Also, your profile is really really inconsistent. How did you attach the probes to the board? You have a 25c delta in your peak temps. Unless that is from a probe lifting, that is really bad. What type of oven are you usi

Three independent heaters control systems. FG-P6000 is available heating portion of the PCB board by hot-air circulate both from top and bottom at the same time. With large IR bottom heating, it can completely avoid PCB deformation during reworking
Lyra Reflow Oven is a soft soldering that realizes the mechanical and electrical connection between the solder ends of surface mount components or the pins and the printed board pads by remelting the solder paste pre-distributed on the printed board
The EVS Solder Recovery system recylces solder form dross using no chemicals or additives, on site, in an efficient, easy process. As solder costs soar, manufacturers benefit from a quick ROI, reusing solder taken directly off their wave and processe

. If the cooling rate is too slow, excessive eutectic metal compounds will be produced. A large grain structure is prone to occur at the welding point, which makes the strength of the welding point lower

. If this condition occurred during a wave or reflow soldering process, then this points to underlying process issues. With wave soldering, if there is excessive solder flow up through the holes, this may indicate the possibility that the board is traveling too slowly in the process
