Hi, Is there any special temperature setting for example , bottom temp should be lower than top temp to prevent component drop. Or any information that can help to prevent component from drop off during reflow of top side.

Guys, Any of you tried running different setting on the top & bottom side temperature on the reflow oven. I'm trying to address uBGA coplanarity issue using this method. Assume board are flat. Any inputs?

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

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

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)

Hi Tim It sort of depends on the solder alloy being used and the particular assemblies being soldered. If you are using the usual 63/37 alloy I would consider 500 to be a bit warm unless the assembly required it. Some alloys would require a higher

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
