Yes Will, I should have said, use tweezers not pliers because if the solder has not quite melted pliers give such a 'grab' that you can pull print off the board.

Once (ha!) you have the pins out, Sod's law dictates that some of the holes will still be blocked with solder. DO NOT be tempted to heat and poke with wire! It will stick and you will be back to square one. You can shave down a cocktail stick or heat and blow but DO wear safety speccs. You will probably get stung on the face but that is part of the fun experience!

Well its immensely depressing as it seems like an impossible task to complete (no pun intended) and its NI's fault for using crap components fitted poorly. I read of another instance of someone having the same problem, contacting NI who sent them a usb replacement (same orange d box) and that only lasted a year before the crackling, failing audio started so there is a pattern.

If this goes belly up, can anyone recommend a suitable replacement that will run Omnisphere and Reaper on a Win 7 pc ? I will not be buying NI again out of principle.

The interface has nothing to do with running Reaper and Omnisphere. As you've been doing this a while, how many inputs and outputs would you like?

The same as the K6 will do me fine.

What do you mean by double sided ?

Copper traces on both sides of the board.

Top and bottom traces are usually joined by holes drilled in the board and then copper-plated inside -- referred to as through-hole plating. Often, component pins are also used to join top and bottom traces by being soldered on both sides... making removal even harder because tugging on a component can lift or otherwise damage one or other of the traces!

It's quite rare to find single-sided boards these days. Almost all are at least double-sided, and many have additional layers inside, like a sandwich, for grounds and power-rails etc.

The copper tracks are printed on both sides of the board, allowing for more complex pathways. The first PCBs only had copper on one side of the board. Nowdays you can have laminated boards with copper tracks in-between layers to save having to have someone manually adding jumper wires between points because there was no logical way to do it with just two sets of tracks.

Connections between layers are made with 'through plated' holes, with copper deposited on the side of the holes to give electrical connectivity. Somewhere between 4 and 8 layers is the norm for multi-layer boards, but up to almost 100 layers is possible.

So even if I get the pins out and fit new there is a good chance it won't work then ?

Well, there's always the danger that if you don't get the solder fully removed (if you try and do all the pins at once) and pull on them, then you could damage the through-plating in the holes. Which is why it's better to try and remove just one pin at a time - which means that you need to physically destroy the rest of the USB socket on the top of the board to get to them.

Also note (if you haven't already) that the two locating clips (circled in red) for the USB port also need to be de-soldered as well as the four data pins (circled in blue).

Yes I am aware of the 6 pins to remove. Still don't know what to do about this but again, can someone suggest an alternative that is as good or better than the K6 (that isn't made by NI) if I need to get a replacement

Quite honestly I have changed a few USB ports in computers and a keyboard and apart from their orientation they are all of much the same constructon quality, i.e. pretty good but definitely 'prosumer' grade. I suppose there ARE ruggedized USB ports but I have never met one, others here more familiar with current kit may like to comment?

Put it another way? I doubt it matters whose AI you buy, the port could still get broken and be just as big a PITA to change, if not bigger than the NI!

But, (and I hate to keep saying this!) the UMC range of Behringer interfaces seem very good and at least if you need to replace it they are very cheap!

I have ordered the usb replacement from Ebay so will have to do this now. Incidentally, the other vlogger who had this problem seems to think it was easy getting it off the board with no need to cut up the component.

He must be amazingly talented then.... Did the unit work afterwards?

Well, I would say that for a very experienced person with full expensive rework facilities, it's not too difficult, but for everyone else - including me - the job has to be handled with great care. You will notice only one of of these pins seems to have a track coming from it. This means all the others have trackwork on the other side, liable to be broken if you attempt to lift the entire plug out.

That makes me even more nervous about this. :crazy:

rest assured nobody is trying to put you off, but we want to give you the best chance of success.

Dave's, advice about flowing some 60/40 leadded solder in there is a very good one, it magically lowers the melting point of the solder that's already there and reduces the chance of board damage.

If you cut open the frame, you can already get the two halves out relatively easily by heating one side while gently easing them out with tweezers from the other side. Once done, breaking up the the remainder is just a matter of looking at how it is constructed and nibbling away small bits with a pair of small side cutters - like these.

Notice they are described as 'full-flush', which means you can cut right to the edge of something.

Yeah Gods Will! nearly 70 quid!

I saw some really fine, wee side cutters in Hobby Craft a while ago. They where for jewellers but will do for Copper jus as well.

Yes, tis a fact of physics that an alloy always has a lower melting point than that of the highest of the elements contained.

Ummm, they were the first ones I came across as a clear and obvious example. You can in fact get very cheap ones - they won't last, but would be good enough to do the job... once!

Never buy cheap tools! Buy good quality. They do a better job and will last a lifetime. I'm still using the tools I bought in 1979, and they are still in perfect condition. £70 over forty years is not a lot per annum...
