TPS7A4501-SP: Reflow Temperature Rating

Hein San

Part Number: TPS7A4501-SP

I am looking into TPS7A4501-SP for its reflow temperature maximum rating but I could not find it on the datasheet. I want to check if the components will handle 220C for about 100 sec, with a maximum of 240C.

Hein,

Here is a link to a document titled "Hermetic Package Reflow Profiles, Termination Finishes, and Lead Trim and Form"

It is also located in the product folders of hermetic devices. This should answer your questions.

If this answers your question, please click "This Resolved My Issue"

Hi Wade,

Thank you for sharing the link, however I still could not find the answer I was looking for. The peak temperature stated in Figure 1-1 says 235C Max <10sec, but the paragraph before the figure states 260C as the max temperature (no duration stated).

Hein,

Figure 1-1 is a "typical" profile. It is not necessarily a recommended profile for a specific flux. The preceding paragraph indicates that package body must not exceed 260 at an time, or it will risk the integrity of the lid seal.

Your profile is within the 260c maximum, and will not cause issues with the lid seal.

We recommend using the flux manufacturers recommended profile, as long as it does not exceed our maximum limit of 260c for package integrity.

Additionally the maximum ramp up/down rates should be adhered to for package integrity.

Regards,

Wade

Do you know how long the component can handle at 260C for because I do not see written anywhere?

I will see if I can get some additional feedback from our packaging team and get back with you.

Hi Wade,

Just circling back to this to see if you have received anything from your packing team. I was able to find data on other 5962 components that says 260C for 30 sec, but I want to verify if this is the same for this specific component. If there is a temperature profile, I would like to see it as well because I'm essentially trying to see if I can use the component at 220C for about 100 sec.

Hein,

I did get feedback. However, it was based on the same document.

Ie, you should not expose to 260c for any duration. If you can point to the documents where it indicated 260c for 30 seconds, I can review this with our packaging team and let you know applicability.

Your use at 220c ( 240 max) is within the guidelines for protecting the package integrity. However, this does not indicate suitability with the flux or reflow process.

Regards,

Wade

I found the information from the datasheet for the 260C. However, it only says 10s soldering time.

Sorry for delay Hein. I thought I had replied to this already.

Soldering temp is different than the reflow temperature. Soldering only applies to the pins/leads, and the body/lid of the package will not reach 260c in 10 seconds. That is why it is allowed and specifically noted.

Hopefully this clears up your question.

Wade
