Incompetance & butchery (warning, large images)
« on: May 28, 2010, 02:27:28 PM »
Received 4 arcade boards today from ebay. What a state some are in.

First board, Goindol


This has been broken by someone levering the chip without desoldering it properly first


This was the desoldering effort. Looks like a soldering shotgun was used


And another

The underside


This ones actually missing altogether so maybe they got one out?

Now for 1942 Bootleg board
This has also been harvested/butchered for 74LS245 IC's




Thankfully the Wonderboy board has been left alone and all that appears to be missing is an eprom from a socket. Fingers crossed thats all it is.
Ill report back on the Lethal Enforcers board when I can actually identify the part thats sort of missing.

Why the hell do people bother going to all this trouble when they clearly do not possess either the right equipment and/or skill to do it?

OMFG! That is just horrendous! That is why I asked you the question re:- what kit we would need to do this sort of repair etc.
I wouldn't dream of prizing chips off a board without de-soldering them properly! We clearly do need a de-soldering station.

I think maybe that will be our next 'large' purchase. Along with other bits needed.

What make you think they weight in gold? it is because it is very rare now?

No mate, he means without a de-solder station you will bugger up boards like the arsehole did to the boards in the pictures.
Trouble is a de-solder station costs around £80, thus £80 well spent!

Although I find a hot air gun (in experienced hands) also does a fine job of desoldering components.

PML!

So, Richard, if we were to get a station then - would you not use? ;)

Yeh, have seen this a lot, its not usually a case of trying to remove the chip without desoldering it, its more often trying to remove the chip after an unsuccessful desolder, usually with a solder sucker which is no use at all. They see that the hole looks clear on the underside but fail to realise its still joined on the top side so end up wrenching the guts out of the board. The speckled mess is the solder fragments that drop back out of the solder sucker when its fired pointing down, so they were trying to desolder, with a weak method in such a way as to be fighting gravity too.  :'(

In my case the price of a desoldering station was < how I value my sanity.

I recall trying to desolder a couple of IC's when I first set out doing this and quickly realised I wasnt going to be able to do it with a solder sucker or braid and I quit trying until much later on when I could afford the desolder station I got. I have never tried the hot air gun method that Phu uses and dont think I would trust myself either.

Desolder station recommendations?

From best of the cheapest to the acceptable of the cheapest of the expensivest, if you see what I mean :)

I don't desolder regularly but when I do I really wish I had one...

This is the one I got. Its fairly cheap as far as desolder stations go. It works very well for me but does have an annoying problem of blocking up with solder very quickly but this is easy to clean out. There is probably cheaper out there and there is definately more expensive but having never used any other I cannot compare

what does this thing actually do, does it have some kind of vacuum system for sucking out the solder?
