SIL9385 Replacement

[mu2]

Hi,

I have a main board with an hdmi chip that needs replaced.
The chip is a Silicon Image SIL9385 and the package is a 100 pin tqfp.

I have some of the low temp alloy that will desolder the pins but this chip has a ground pad underneath.

Can someone recommend a way to remove and reinstall the new chip? I have a hot air station but no preheater for the underside of the board.

Thanks,
Mike

Re: SIL9385 Replacement

If the chip has failed you can use hot air to remove. Getting it too hot doesn't matter.
Once the old solder is removed you can use solder past for the centre pad and hot air to replace.

maybe use a hair dryer on the underside of the board whilst heating it from the top with your air station i know it wont get as hot as a proper hot air station but any extra heat will help with removal.
