Hi I have been conducting my first reflow profiles. Most of the texts that I have read suggest soldering the thermocouples to a populated pcb. I am finding this very difficult. I have been using a high melting point (Sn5 / Pb95) solder and the diff

I am working on 0201 development for my company in the UK, and I am planning a rather extensive DOE for my reflow oven profile. I am planning on studying various ramp rates, soak times, times above liquidus, peak temps, etc... My biggest concern

| Micheal, | | What does your profile look like for the wave? What profile does your flux say you need? My guess is it is not your profile, our testing with solder balls found that the mask on the boards was the largest contributor to solder balls

| My question is: How does one recognize paladium leads so that the profile can be set properly? | Dave F Hi Dave, It's kinda' subjective, but what I think it looks like is almost like having a nickel appearance to it, it's smoother and not as

Take a look at http://www.atco-us.com/products/info/3 . Benchtop version is also available. A full forced convection oven delivers much better thermal uniformity than an IR/forced air combo system. When comparing different ovens, some things to

I have a pcb with an ENIG finish that is using a 144 pin LQFP and being soldered withSN100C/NC258 T4 paste. I used a oven profiler where the probes are taped down to the joint and the profiling software adjusts the program for the best profile for

Are there other components on the board? If so, how does solder quality look on them? Are they all reflowing? Are the sections of the uBGA�s sitting on a ground plane? Sounds like un-even heating. You should attach a couple thermal couples and see h

Hi Barry, Your best course of action is to perform a thermal profile and determine exactly what the times/temps are in these locations. Try to match your profile to the recommendations of your solder paste. (Time between 130-160, Time over 183 and m

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