Sr. Tech, As far as I’m aware, most if not all, manufactures of thermal profilers offer K type thermocouples as a standard for profiling in the electronics manufacturing industry. In my decades of experience in the reflow and wave solder industry, t

So I am reading about K type thermocouples in the IPC 7530 Guidelines and it says : "At temps above 250c it may suffer from temperature cycling hysteresis and may not be the best choice." Uhhh... It looks like the best choice is an N type thermocoup

I am not sure what the IPC spec is suggesting....K type thermocouples are normally specified upto 1250 C, of course there is a tolerance in their accuracy and this probably degrades after hundreds of uses through a reflow oven, but normally the accur

Hi, The focal point of my research has been to recommend a reflow oven and develop a process for a small to low-medium production SMT soldering with the following considerations. - Lead-Free - Low to low-medium production - Forced Convection reflow

If it's not adhesive, try an ESD-type ionizer. The objective of an ionizer is to eliminate surface charge on insulators and on isolated/ungrounded conductors. Practically speaking, the action of an ionizer is to drive the voltage on the surface of a
