Am I the only one who doesn't think resistors standing up is a bad thing?  That op amp feedback resistor between two adjacent pins will always stand up in my layouts.

I don't like how, in a worst case scenario, it can be wiggled back and forth until the legs break. That's a lot more unlikely if the component is flat.

> it can be wiggled back and forth until the legs break.

I recall dozens of pocket transistor radios, and many cheap tape portables, where ALL the resistors stood up with no support. I do not remember this being a failure point.

Yes, you would think that life On The Road (thrown into bag every night and driven over bad roads to the next gig) would shake the legs. But we didn't coddle those pocket radios either.

But obviously this is Designer's Choice.

I do like the fact that if you pick which leg you are most likely to need to probe, you have a fantastic stand-up clip-on test point.

That's a great idea!  I'll factor that in when I design my next layout.

Technical difficulties.  Please stand by.

Boss, Ibanez, and many others have been doing this for decades.
That's one of the ways these companies accomplished making stompbox footprints smaller.
I don't recall ever hearing about this being a failure point either. A soldered lead is a soldered lead. There is no weight to resistors to cause a stress point on the connections.
If you want to open up an effect with resistors standing on end...wiggle them back and forth until they break off....that's another story.   :icon_wink:
The only complaint that I've heard on this and other forums....it's more time consuming to install resistors in this fashion.
I agree...but...some boards that I've designed and built would not have fit in a smaller enclosure if I installed resistors in the "normal" fashion.
I just designed a new fuzz circuit! It almost sounds a little different than the last fifty fuzz circuits I designed! ;)

Oh, I know, and absolutely agree, but now my paranoid OCD won't leave me be if I do it with my own boards.

Don't give in to it! It only makes it worse!

(I not only put all my resistors in flat, but I also orientate all the stripes the same way around...is that sad?!)

Good practice. I hate turning a chassis around and around and around to read the parts.

(Yes, I can read color stripes most ways, but capacitor and IC text is less prone to mis-read if the data is "up" all the same way.)

Tom, thank you. I'm not alone!! :-D

Ohm's Law - much like Coles Law, but with less cabbage...

duck_arse

count me in with the right way round resistors, too. the girls on the line were "encouraged" to face them all the same way.

Hohoho! Looks like a good dose of OCD is pretty much essential if you're going to fit in around here, then ;)
