How to solder this chip?

How to solder this chip with small pins below ?
Does someone know some bottom to put chip into and then solder bottom pins to PCB?

This is an 192-ball BGA-package. I would say it's impossible to solder by hand. But you should do a search in the forum for 'solder && BGA' and you'll find some approaches ...

Good luck,

You need a heat air gun for solder this type of chip. :lol:

I didn't download the file for the chip so I will take the word of the other fellow that identified it as a 192BGA.

I don't think this could be done without a hot air solderstation made for BGA chip placement. I have worked with many experienced assemblers that would shrug their shoulders without this equipment.

You could try a hot air gun, but I wouldn't expect good results even from an assembler with 10 years+ experience.

Smaller BGA's might be possible, by hand, with a hot air gun.

Good luck.

Oh, you could take to a contract manufacturer and have them do it for you. About $35 if I remember correctly. #### Element_115 ##### Advanced Member level 2 I agree with Prouddad_1. Also you will need to have an X-ray taken to see if all the pins/balls are truly connected. This saves you time in debug , a trip back to that company, and possibly a chip that might blow if a VCC or Ground is not connected or shorted. It cost my old company ~$50 USD for up to 3 on one run.

If you do it by hand very be careful

Good luck

A split vision system such as a SNIPER is the way to go. I think this is way beyond hand soldering with a hotair gun.

BGA equipment

The sniper is easy to use/easy to learn. Pricey if you're only doing a few chips and not justifiable. We needed it for ic development, so it was a necessity. We also managed to use ours for a makeshift temp test station.

OK industries also makes bga soldering equipment but I don't have much experience with thier equipment.

This is almost impossible to do without a hot air gun or soldering oven.
Other methods can destroy the chip.
