When I first started work I was sent to the stores where they gave me a tool box and a standard set of decent tools. However, after a few years I worked for someone who thought that all tools should be communal - the problem was they all seemed to end up in his office! So I ended up buying a bunch of those cheap (£90-ish) electronics toolkits that you can buy from CPC and keeping one of them hidden under my desk so that I knew where I could find a certain tool if there were none left in the lab. While they may not be the absolute best quality, most of the tools were certainly usable.

Once... As a work experience gig for a week when I was at school. It was a Gossard bra factory... Quite an experience for a green teenager I can tell you! That many women machinists together can become positively feral! Misandry a go go... But I did learn a lot about practical industrial power-factor correction :lol:

I heard Gossard went bust :D

But an Uplifting experience when he was there. Then he crossed over into another field.

Heh! I had a similar experience when I was about 18 or 19. I was sent to a dress factory to look at the PA system. Can't remember the fault but I DO remember having to walk through a vast machining room of about 100 women to check the sound coverage. I was a very odd colour by the time I reached the end!

Taught me one thing about PA systems and the general public though? You can NEVER bloody win!

Back on topic, my fresh new USB has arrived so I have to decide weather to go in or not. Again, it seems an impossible task cutting up the duff one leaving just the individual pins. Can't each pin be de-soldered (sucked up/wick) via adding 60/40 (whatever that is) ?

You have to get that shell opened out first.

The way I would do this would be to use a junior hacksaw blade - just the blade not the whole saw, and with the teeth pointing the 'wrong' way so it cuts when you pull. Cut right down to the board itself but be careful not to cut into the board. Then you should be able to pull the halves apart a little and separate the metal part of the outer shell. Thats the time to start snipping away at it and the rest of the gubbins inside.

Due to the shape of the shell you will probably end up taking the four pins out before finally removing the shell.

I'm still not sure exactly what you mean. Cut down vertical or horizontal ?

Anyway you do! Just don't cut the PCB or other components. Personally I would not use a saw blade, it will leave conducting swarf * on the board. I have never met a 'tin' connector I could not prise apart and destroy with side cutters!

*Not American English it seems?

My wife has a pair of those parrot shaped jewelry cutters if that would do it ?

I'm with Dave... I wouldn't reach for a hacksaw blade as a first option for the same reason -- lots of metal swarf that you'd need to clean out carefully to avoid shorts, and much higher risk of accidental damage to other components. Not hard, but more hassle you don't need.

The USB socket is only made of bent tin, so any reasonably solid side-cutters ought to be able to destroy it provided you take it in small chunks at a time.

As to your parrot cutters... try them and see...

What concerns me is the 4 pins that should be coming from the USB are only 3. I haven't broken any off. Also, will having the iron set at maximum temp have damaged anything the last time I tried this ?

Hadn't noticed that. rather suspicious. I wonder if the pin got bent when the socket was inserted and is sitting the other side of the board touching the contact when it feels like it. That would certainly account for the flaky behaviour.

So what would you suggest is my next step, bearing in mind after trying to desolder a couple of weeks ago, it hasn't fixed anything as I just tried it in the usb to the pc and nothing happened. Not even a crash of the pc.

The photograph you posted doesn't look like there has been much de-soldering accomplished.

When you've mentioned 'wick' are you talking about copper braid? I've found that good. It can take a lot of wick to get solder off, so I start with a solder sucker to get as much off as I can.

The solder sucker and wick take some experience to use effectively.

With wick you have to cut off the bit you've used. The braid should be flexible. When it goes stiff it has absorbed solder and you have to cut that off. That could explain the sticking you described above.

Also the shape of the bit can make a difference. For this I would use the one that is an obliquely cut cylinder shape. Use the flat surface of this bit to get the maximum contact area.

And as is the consensus above cutting up the old USB socket will make it easier to remove.
