Hi guys, Whats actually Delta T ? As i know,its applicable for reflow profiling. Recently my superior asked me whats the Delta T for heating settings on my reflow ? Does Delta T applicable for heater setting on my reflow ? Pls advise as i m puzzl

When Delta T is measured between components on a PCB, it is recommended that the Delta T between your highest mass and lowest mass component be 4 degrees C or less. Delta T can also be measured between zones on your reflow oven. (Delta T is defined

I can provide you with a Dundas chart to tell you delta Tea.

How does the delta T on the board relate to the delta T on the component?

another delta wave have the same fault, same symptoms!!!

thanks for the feedback....but what's your delta T and how will you know that you are within the delta T range ?...I think this is the main point of the above topic...can you elaborate more on how did your company get Delta T ? thanks and regards,

Delta T usually refers to the Temperature Difference between adjoining zones in your Reflow Oven. The recommended Delta-T between heating zones is http://www.ipcoutlook.org/pdf/best_practices_reflow_profiling.pdf

I was asking about delta t in profiling, because I have just started to learn how to do it and wanted to know about it. So how can you reduce delta t, so you dont go from cold to hot too fats. Is it enough to slow donw conveyor speed??? Thanks M

What is the rule-of-thumb on wave profiling Ceramics? I've used 2 methods: 1.) putting the T/C on the lead, and get a pretty good delta (within 50-80 deg. before hitting chip wave), well within manufacturer's spec. 2.) Right on the part body.
