What type of product are you talking about in SMT? The SMT05E series are non-isolated DC/DC converters packaged in a surface mount footprintgiving designers a cost effective solution for conversion from a 3.3V to 5V source. Operating Temperature is -

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

Hi, I use convection reflow and both top & bottom settings are the same. Is the part too heavy to rely on surface tension? there is an equation that can determine this (aswell as real test i.e. part falling off) We have some SIM Card holders on bot

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

The lowest peak temp. I've had the pleasure of working with is 240°C +/- 5°C. I can't imagine a manufacturer going much below that and still saying it's lead-free compatible. It would be interesting to know just how much TAL plays into the affect

CAL's word of caution is right on. We tend to stay in the 220C-225C max. temp. on our profiles, and that's because the last heads up from engineering came on a part with a spec. of 230C max. temp. We just found out that one of our old SOIC's is spe

Tim, I try to get 2-3 degrees C/sec (bottomside) rise on my boards through wavesolder. I like to get the topside to about 90-95 degrees C, but this is the optimum temp for the flux that I am using. To fast of a slope and you will burn your flux of

I have, but not for what you are trying. Different ovens and styles react differently when you try this, so you have to experiment to see how far you can go. Why do you think different temps top and bottom will solve the coplanairty issue? Is this
