Reflow profiles are based on the product and materials you are soldering. You need profiling software and a data logger.

All data loggers will be warmer at the higher lead free temps. Only two ways around this... better thermal barriers or fans after the profile to cool it down. Some places do not allow fans on the production floor due to static electricity, in that

IIRC the IPC spec for oven profiling says the thermocouple leads should not be more than one meter in length. I think when you can afford it, getting a data logger to go through the oven would be a good idea. But if you are going to use the very lon

Thanx aj and Russ. I will verify my ramp up/down degC/sec and the soak zone peak temp. Fluxes could be burning off prior to activation. I have found access to an old thermal data logger to help verify the Heller thermocouples. I will post updated fi

You must thermally profile your circuit boards with a data-logger and thermocouples. Just putting in oven set points and looking at solder joints is not enough. Reference IPC-7530

Hi Forum. Is there anyone who can tell if an empty PCB with no SMD components mounted and HAL surface will get a less solderability after been running through reflow (convection). Eg. when testing empty PCB with temperture data logger. Regards Ole

His suggestion is that you come into the 21st century and buy a data logger rather than feeding wires through the entire reflow oven. That is old school and it is very cumbersome as you undoubtedly know. If you are in a position where a logger is no

Daniele The other repsonses have it right. The junction of the wires measures the temperature. If your poduct needs to be re-used I would suggest either kapton tape or aluminim tape(the better of the two). If this is your "golden board" I would

Vick Russ is very correct. Get the paste material specificatioin. Please get your favorite data logger (ECD, KIC, DatPaq, etc..), attach some TC's and take a profile. This is the ONLY way to know what your reflow system is doing and how to alter.

We run humidifiers in our shop because we are usually around 25% RH. We track this with a data-logger and RH device. It's dry here! Sometimes in the summer, it can get between 5 and 10% RH outside = thunderstorms/dry lightning and forest fires. I
