Playstation 1 SCPH-101 Accidentally Bridged Legs

So the trickiest part of installing a modchip for me is actually pin three, because you have to solder the wire right in front of the tiny chip. So I effed that up, and bridged the row behind it. Are there any tips on what I should do to fix the chip or have I screwed it up? The system only hangs at the Sony Entertainment Corporation screen.

Should I follow this: , or just simply use a desolder braid in conjuction with flux until all of the pins are dry, and then proceed with a new drag solder? Is so what's a technique using a regular 40W iron?

I'm definitely going to buy another system, btw. But would like to learn how to deal with this catastrophe.

 

Just use braid. Resoldering shouldn't be necessary since you won't really get the solder that's under the legs (connecting them to the pads).

 

^^^ agree with rso. Just apply flux to pins and use braid. If the bridge isn't too big, u may get away with touching to iron between the legs, the flux will draw the solder to the individual legs. I've done this plenty of times especially with fine pitch QFP packages. Just be careful with your 40W firestick. Try to get a variable wattage ESD safe iron with fine tip in future.

 

Well. I worry that the solder may have bridged under the legs, and I hope they don't break that easily.

 

Use a bit of flux and some braid, the flux will help create a surface tension on the solder and should encourage it to pop onto the legs and remove the bridge, and use some braid to wick it up. I cannot overstate how useful flux is. Seriously. when soldering tiny pins, flux is your best friend.

 

Ah it's foobared. I couldn't remove the remaining solder since it seeped under the legs. And then I accidentally removed the resistor next to point 3 on the chip. I spent 10 minutes trying to get it back on. Now, the disc drive is going insane, which is related to my poor placement of point 3.

At least it was a learning experience, and I have a spare laser to use.

 

Not to worry, I've broken many a part when learning to solder - and I still do! It's all part of the learning experience.

 

Its not broken, someone could fix that pretty easily.

 

Hmm... If I remove all the solder from that side of the chip, it should still work fine as long as the legs touch the board, because the other sides of the board are secure? That solder has definitely went under the legs.

Is the disc spinning really related to my screw up on point three? Though will have to check next week for the just as hard points of 2 and 6.

 

Looks like I fused the legs of the bios chips or something.

So I also got another unit in, and swapped in the laser. I know the laser worked before, but in this one it just gives up after an initial spin. This new unit has not been modded yet. Anybody know what causes that problem?
