Yamasa - Acid Rot problems?

[delphicoder]

I read online elsewhere that the Yamasa line of pachislo has a problem with acid rot on the circuit boards

Has anyone here experienced any of that with Yamasa machines? That would really bite. I have Kung Fu Lady II, and was looking to add Wild Wolf, both of which are Yamasa.

Glad my Gold God and Don Don King are other models!

Thanks.

I think as long as you keep it out of the acid rain you'll be fine! :lol:

I heard that a long time ago, but my oldest machine is a Yamasa and I've had no issues.

I've only seen this mentioned once - on the PachisloUSA forum. I think they were commenting on something they saw on a very small sample of machines. Any manufacturer can get a bad batch of boards from a sloppy subcontractor. I wouldn't worry about it unless it starts showing up on a much larger sample of Yamasa machines.

Anyone here have a Yamasa fail?

[gwarzin]

I suspect a bigger problem with machines is exposure to salt spray during while their in a sea freight container.

You are right, that is where I read it. Looking at it again it was back in 2003. Hopefully it was an isolated incident.

Thanks!

What is acid rot?

Worst case scenario, you cna usually get another board in place of a bad one. Alot of machines use the same ones.

What is acid rot?

When they make the circuit boards they use acid to etch them. This should be washed off with a neutralizer. If it wasn't washed properly some of the acid remains and continues to etch the conductive surface.

I still see this a lot. I haven't seen a machine fail because of it yet, but it is only a matter of time... Also see it on some takasago machines..

I will post a picture to this thread in a day or so, so that you can see what it looks like.

With my luck, Wild Wolf and Kung Fu Lady II will die on me promptly because of it.

like alfred e. newmann used to say "what-me worry"

or is that a name of a song--i forget :roll:

i wouldn't lose any sleep over it :-o
