Hi there, where can I find some hints about placing the temperature sensors on the pcb when determining the reflow profile? I'm interested especially in the case of a pcb having BGA's. Thanks for your answers ! gheorghe

Don't know the specifics from the IPC spec. However our standard internal spec dictates - highest thermal mass, lowest thermal, most critical component, and center of PCB on the laminate surface. Our profilers have 6 inputs, so the other 2 are dete

Hello, usually you will place your themocouples on the most critical parts on your board. I would say, very big parts, very sensetive to the temperature parts, heavy parts, parts with big heat-sink.... The easiest way is to solder your thermocouple

Hi, There is one thing missing still, you must put a TC from the bottom side of the BGA by making a hold on the test board at the TC can measure the temperature at exactly the middle of the BGA. You should be able to the dual time and peak temperatu

I would agree if you have a board to setup the process. But sometimes this doesn't work... If for some reason if the customers AVL has a Lead Free BGA and I am running Leaded paste (yes this really happens!), you will need to run hotter to get your
