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

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

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

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
