PCB, which one?
- TV-Set
- Breadboard Brother
Sorry, somehow the forum won't let me post it in the right section.
Anyways, I was designing my own pcb layout for the MXR Dist+ when I had this doubt (so I made 2 of them)...
Which one is better/correct or whatever?
#1 like the original vintage pcb
#2 like the ones you find on the web
Those are completely the same layout-wise

the same circuit, yes. nut what's with all those thick lines? what r they 4?Seiche wrote:what is your question? they are the same thing

Well, under my point of view, if it's in the board you're using it; if it goes with the acid, you're wasting it.Seiche wrote:how? The copper's already on the board? Maybe to waste less acid when etching?Duckman wrote:Just to waste less copper. Use whichever you want.
Any way, as Seiche rightly pointed out, you'll end using less acid... just a little less, unless you're going for 50 boards
Just choose one and do it, dammit!

lol, yeah, I'm not making 100s of em, just used my 1L bottle on one board so far... so it'll take some time to consume itDuckman wrote:Well, under my point of view, if it's in the board you're using it; if it goes with the acid, you're wasting it.Seiche wrote:how?

Oh, just one more question while I'm at it. Yesterday I made my 1st pcb (not this one, I made RAT from tonepad, modified a little to use a led indicator and such) and I found that the toner kinda melted and spread over the board too much, no overlapping threads though (the writing got all wacky), just got wider pads and all... so, here's my q. - if I left it in the acid for more time would the copper get etched more on the sides of the toner threads, to make em not as wide? or should I just use less toner so it doesn't melt that much? (woops, that's 2 Qs)
PS: the RAT works all right btw, so apparently I did a good job there... but one always tries to make things better... and one does not simply walk into Mordor...

Overmelted toner traces occurs during ironing, mostly when you apply the iron too much time, or the iron is too hot, or both. If you like to reshape some trace/pad to something near to his original width/size, just use an exacto knive or some sharped piece of metal and a magnifying lens to carefuly scratch the excess toner. More time in acid will not do the job. In fact, you just need that traces don't touch each other, so if look a little ugly but it works, take it.

Indeed, just finished my second pcb (Dist+), spent half the time ironing (less than 5 min) and the lines are much better. Practice makes perfectDuckman wrote:More practice will improve your skills.

PS: as for which design to pick, I'll definetly use #1 for my next project, looks tidier, pads and traces are far apart, less mess when soldering...
