In short physics. A large Black object will absorb more energy than a smaller non-black object. Thus the temperature will remain lower around the black object as it heats up ! sarason

Different points on the board couple have different thermal masses. Look here: http://www.ecd.com/portals/5/products/vmole/V-MOLE-Verify-3-Thermocouple.pdf

Dear Davef Thanks for your information. I already have measured it at the same position for 2 kind of component but the result does not change. Pls help me...

We're not sure what you mean by temperature sensitive components. From an assembly process stand-point, every component we use is temperature sensitive to one level or another. More specifically, some of our products use polyphenylene sulfide (PPS)

In general, smaller objects heat up faster than larger objects because they are lower mass. For example if you heat up one liter of water in pan and two liters of water in another pan with the same heat energy applied, the smaller mass will heat up f

Hello, I want to ask on suitable temperature profile for PCBs with ENIG final surface finish. I know that it is complex question with many unknowns. When the PCB will be standard 1,5 mm 35/35 Cu and the amount of components will have any influence o

I'm not a Wave soldering guy and my friend have asked me a question on what is the best preheat time and temperature for Wave soldering.They experiences only 10% flow up thru the PTH barrel. I've asked them to increase the temperatue to 120 Deg C. Cu

You guessed right. Not hot enough to get good reflow. regards sarason

What temperature spec are people using in the industry to make sure an electronic component is SMT reflow compatible ? Ex. I have some parts that I want to possibly process as Pin in Paste but am not sure what temperature ratings the plastic will m

Hi , As far as I experienced with wave reflow. If u have a refective thermal reader , u will see that the board is exposed to much more temp than the 120 deg that u set. Actually , once u see the board warp or comp. crack u should know that
