Actually, you don't need very long thermocouple wire. Just bond your t/couples to the desired board positions and plug them into a data logger that travels through the reflow oven with the board. At the other end, you unplug the data logger from the t/couples and plug it into a printer with a special docking port and it just prints out the profile of the temperatures achieved by each couple on its journey through the oven. Then if you need to tweak the temperature settings of the zones, you can do so and run the profile baord through the oven again to verify that everything is OK and get another print-out straight away - very simple and convenient.

Hi Brad, Why not use a temperature datalogger, kapton tape and some long thermocouple wire? There are many sources but http://www.omega.com would be a great place to start.

We are trying to implement a system where we profile the first assembly of every new run through our reflow oven. We are currently using high temperature solder for profiling. If we start to use the high temp solder for this, we will have to scrap the assemblies. Does anyone have any suggestions for alternatives to high temp solder? Any suggestions would be greatly appreciated. Thank you, Brad Smith Process Technician Badger Electronics Co., Inc.
