How to use an IC comes in BGA package in a breadboard?

[rixxy]

i'm using a an IC comes in 48pin BGA package so i cannt put in on a breadboard to test it so i need some kind of carrier or socket that can carry this ic and convert the its fine pins to bigger ones..
please help
Thanks

You can either solder it to special adapter PCBs that bring out the balls to a standard 2,54mm grid. They cost some $50 per piece and can even be made by yourself with a PCB design package.

Or you can use a ZIF socket for BGA. They cost some $500 per piece and they fit only one group of devices. If you for example test 48-ball FLASH chips, you need one socket for Intel uBGA and another one for AMDs plastic BGA.

Good companies are YAMAICHI and EMULATION TECHNOLOGIES

jetmarc,

How to solder the BGA to the adapter PCB? Do you use hot air blower or what? Obviously a soldering iron doesn't work here.

Hi all,

Is any body having detailed documentation on device modelling in PSPICE?

Thanks.

This is a difficult task. To do it right you have to use special oven and a placement system with half-transparent mirrors.

Some people have successfully soldered BGA at home, but this rarely works. You can't use just air blower because it blows away the chip.

Try placing the chip on a heating plate or Infrared heater to reach around 150 degrees on the whole PCB area. Then use hot air or IR to raise just the chip up to 230 or 250 degrees. That's easier than from 20 degrees room temperature :smile:

You may be able to find a board house that can solder the BGA for you. Some technical universities have BGA facilities, too.

If you're just testing a single chip (or for example want to read out a desoldered flash chip), you're much better off with a ZIF socket from Emulation Technologies!

Hi jetmarc
thanks for helping but can you tell me an example of those special adapters you told me?i need part numbers please because when i was looking for an adapter for that 48BGA i didnt find any that can fit it..forget about the ZIF socket becsause it's expensive for me to buy it

You have to measure the ball spacing of your chip. Measure from middle of 1st ball to middle of 11th ball. If the distance is 8mm, the spacing is 0.8mm. If you measure 10mm, the spacing is 1.0mm.

The PCBs have hundreds of pins. You simply solder the BGA into a corner of it and ignore the other pins. You can even solder two different BGAs to the same board, it shouldn't be more expensive than soldering just one. (in a board house)

The PCBs are professionally made and I used the 0.8mm one recently to pop an ASIC.

There are few vendor provide an adapter
that convert 1mm BGA to a PGA

Check ***.andonelect.com for rollerball

and ***.advintcorp.com, I got a free sample
from them
