It's worth a shot, but there may be a chance that the "ROM" isn't quite compatible with the fw on your drive, it happens.

Then you'll need to "ROM" chip over from the bad PCB.

New!! HDD-PCB.COM for all your PCB and donor HDD requirements!

Hi again today i received a donor hard drive hoping for a straight swap but no luck hard drive is spinning, if i connect it directly to pc it will not boot and i cannot get into bios. When i connect it to my external HDD bay it doesn't show up......its looking like im gonna have to try swap memory chip...How hard is this? I have a some soldering experience but the thing does look tiny. Ive got some copper braid for desoldering


Hope you can help


thanks

You don't want to use a soldering iron and you dont need any more solder. Is this data important? Would hate for you to cause more damage when this is a very easy fix for a pro.

It's a very easy job for a TV/AV pro. Your local TV repair shop should be able to do it.

many people use hot air rework station, but I use this small thing on soldering iron



It is an modified aluminium screw. Its purpose is easy.... heat all pins at once and quickly remove it, but it needs a bit practice. (Thank you dad for your idea )

hi all thanks for reply's....I'm pretty sure ive got lots of photos on disk but i'll need to check other hard drives to confirm this Ive sent pm to "pcimage" hopefully he can help me out if not i will attempt it myself but last resort


thankyou all

Nice idea. I just love those MacGyver solutions. :-) However, someone may have beaten your father to it.

I first evaluated an smt rework station (Pace MBT 201) about 20 years ago. It used a set of expensive tips for each IC package type. These tips straddled the chip and warmed all the pins by direct contact, just as yours does. To me, these are a lot gentler than blasting the job with hot air.

Here are some modern examples:

Unfortunately they cost a lot more than an aluminium screw, but ISTM that they would be a worthwhile investment for someone who is concerned about heat-induced deterioration in weak flash cells, for example.

With a hot air rework station/wand (sometimes incorrectly called a heat gun) like the Gordak 852 or one of its variants, it's a piece of cake. Just use a 5-7mm nozzle and heat the pins, not the IC. After a few minutes of air at ~350C, you can just pick up the "ROM" with tweezers. Put flux on the pins beforehand. Soldering it onto the other board is also easy: apply flux, position the IC, heat the pins while you hold the IC with tweezers and watch for the solder to flow. When it's all liquid, gently press down on the IC to seat/secure it and remove the heat. Don't use too much airflow or it'll blow the part(s) around.

If you are going to use a soldering iron, get some ChipQuik low-temp (Bismuth) soldering alloy. It lowers the melting temp of the solder so you can just push the IC aside once it's been melted into each joint.

You sure it's wise to heat ROM for few minutes?

20 - 30 seconds should do it.

I did not recommend heating the ROM, I suggested heating the PCB and avoid heating the ROM directly. Sometimes it takes just seconds--depends on air temps and speed. Whatever, you just keep prodding the ROM until it moves, then lift it.

Hi just to update you all. I sent both my PCB boards to sean at pcimage who did an excellent job on swap rom from bad board to new board. Hard Drive is now working


Thanks

Nice
Now, backup.

Good work Sean!
