Solder Joint Reliability using ANSYS Mechanical

More details at www.singularit...
Thermal cycling is one of the most common failure mode in electronics. This is a demonstration of the Darveaux method for Solder Joint Reliability simulation using the Anand Viscoplastic Model. This technique helps engineers to predict time to failure during accelerated thermal test.

Great video. One suggestion, ditch the background music. It is louder than the speech.

Hey Mingyao, thanks for this great video that covered multiple tips I am looking for. This is my first view but I am sure to be back later for more details when I start working on similar problems.

Instablaster.

Hi, may I know where can I get the Anand Viscoplastic model for the solder joint?

[@yangli411]

How long it takes in general for this calculation? Several days? Greatly appreciate any feedbacks!

[@SingularityEngineeringLLC]

About an hour and half on my laptop. This type of simulation is highly scalable so you can through a lot of CPU's at it for large models.

[@muhammadejaz5870]

and sir how to put young modulus offset and scale because when i put the values so only young modulus comes not offset or scale

[@hasanomar7071]

Hi sir can you show us how you design it from frist step by step

[@ongkaichyuan5930]

Hi sir can i know that whr should we go and download the file for solder type

[@rushikeshtagde7312]

name this software used for meshing

[@devilangel4980]

Why do we need to cut 0.001 inch on top and the bottom of the solder joints? Thank you

[@suryashekhar5554]

Because that's where the crack initiation and propagation takes place, a closer mesh in that region would give more accurate results

[@omarahmed418]

Great video! Can you please tell us from where did you get the solder joint fatigue object inserted into the solution ?

[@DFactoryHouse]

I am also looking for the answer, where can I get the solder joint fatigue add on package? I found one in ANSYS store, will that helpful?

[@人蔘海海]

Sir, is the plastic work mentioned in the movie calculated using the volume average method? Thank you!

[@briankelly3194]

He says it is when mentioning the add-in that he is using.

[@Better_Life4321]

Can you please send dimensions of design you used.

[@武新龙]

Hey Mingyao，thank you for your video…… What is the difference bewtten plastic stain energy density and plastic work/volume

[@briankelly3194]

They are the same

[@husseinmohammed8765]

can you show us how you design in begging

[@deanw8206]

Are there any canned models for solder that I can use for this? Is there any way you could provide the xml file that you used? Thank you.

[@DFactoryHouse]

@Dean W, did you get the xml file?

[@deanw8206]

I didnt

[@Better_Life4321]

Hai Mingyao, thank you so much.. I have some doubt in this analysis. Complete model by ansys or some other desigining software.. can you send me link of ACT extension of solder joints..

[@Better_Life4321]

Why you did share topology?

@@briankelly3194 yes Brian. Thankyou

[@muhammadejaz5870]

sir can you send that solder material property file

[@suryashekhar5554]

you can use SAC305
