ChipScale 4mm 10 pin IC MESS

Hi Guys

a Couple of days ago I opened up a package that I was really really excited about cause it an IC that is going to make my life ALLOT easier but to my surprise it happened to be miniature and I will not be able to solder something this small...
Its a 4mm 10 Pin IC. So to my disappointment I searched the internet for solutions but didnt find anything.

Is there some kind of IC Socket that I can buy that will be easier to solder and just insert the IC into it or am I screwed since I dont have Super human patience and robot arms to solder this thing?

Please help guys I really need this ASAP.

Thanks and regards.

If it has leads you can definately solder it by hand. Do you have a part number?

There's so many different package sizes, can you give us more details about the IC itself, maybe an order number or the name of the package type (ie SOIC, QFN, TSSOP). As it's 4mm, it's more than likely a QFN.

What are you attaching it to as well? Is it a PCB??

Check the datasheet and tell us what is the package type. We may help you to find an adapter. The following youtube video may also be helpful.

Hey thanks for all the quick replies really appreciate it.

Ok on the questions belowe.
Julio: Do you mean Leads like little protruding legs ?Because it doesn't have those unfortunately.

Mike: The Package number is MTD6506T from microchip and its the only one of it's kind that I can find locally BUT please if you know of any that I can order on line please let me know. Its a BLDC 3-Phase Sensorles motor driver.
Here is the Data-sheet url : http://ww1.microchip.com/downloads/en/DeviceDoc/22281A.pdf

If its possible to find an adapter that would be AMAZING!

Thanks guys

Jiajun: Its almost exactly that size and looks the same.

I checked out the video and its really help full accept for when he gets to the applying soldering paste toe the tracks.
Why does he apply soldering paste all over the tracks because that would short them all out right?
He talks about masking something? Is it some way of getting the solder paste to remove itself from the green parts of the board upon warming it up?

Thanks guy

That Video Jiajun posted was extremely use full accept for the cost of getting a hot airgun and also soldering paste.
I am a student so things like that is quite expensive to me
But so far that was the best method ive seen so far.

Anybody else have some ideas?

Thanks

I would suggest a combination of a SchmartBoard solution:

and the following videos:

* http://www.schmartboard.com/index.asp?page=resources_howto [a list of how-to videos for doing the actual soldering]
* http://www.youtube.com/watch?v=5uiroWBkdFY&feature=BFa&list=FL-ZrKXeoeVOTGC6IDLNQDxQ [excellent video on using a chisel tipped soldering iron to solder SMD chips - I use this technique all the time -- it works great]

Ahh--sooo... that a leadless UDFN, which requires different handling. Try these videos:

* http://www.youtube.com/watch?v=846xIq3AIs0
* http://www.youtube.com/watch?v=c_Qt5CtUlqY [the first part of this video offers some pointers for hand soldering without a hot air system]

There is a layer of solder mask (green color coating) on the pcb, which covers the whole pcb except for the soldering pads. Solder has very poor wetting on the solder mask when it melt. The solder automatically separates when it is heated up. If you only have bare pcb, you can try the following adapter (Actually same thing mentioned by steve):

Yes, some smaller dimension ICs can be solder using a hot air blower.
Have you try that? But go through the IC data sheet and be sure of the temperature that the IC can withstand so as not to damage it.
Adopt the above videos they are self explanatory.
Do not hesitate to ask for more explanation if any.

They're really good videos, I'll definitely have a look at them again next time I'm soldering.

Those Schmartboards are pretty cool too. The 202-0016-01 (http://www.schmartboard.com/index.asp?page=products_csp&id=74) would be the best part (using the LFCSP20 down the bottom left) for this UDFN, the extra pins would not be connected to anything. The spacing is correct with a pitch of 0.5mm, the dimensions of the pad are 2.794mm squared. My only worry here is that the Schmartboard diagrams aren't super detailed and I can't tell if the tracks will meet under the ground pad. But I'm gonna guess it's alright.

My other issue here is the ground pad underneath the UDFN part. However the datasheet says the ground pad can be connected for better heat dissipation, depending on Cart's usage, it may not even be needed and he could probably leave it alone.

Cart I'd say go with Steve's option here. If you get the Schmartboard, you should be able hand solder that part as per the video without too much hassle. My only warning is to use a multimeter afterwards to verify none of the pins are shorted to each other or the ground pad underneath.

hmmm... I'm not up on how the ground pad is treated in the industry but for this kind of usage, i wonder if a little dab of heatsink compound would do the trick -- since, I take it that only a thermal connection is necessary. But, I would make sure the compound didn't get onto the other pads, so I would use a very small amount. On the plus side, the compound might help hold the chip in place while it's being soldered.
