Title: The most Jam-packed PCB
Post by: somnif on March 31, 2017, 01:58:11 AM
I had the opportunity to play around with an MXR Carbon Copy today, a personal favorite in the realm of analog delays, and afterwards I had the opportunity to unbox the thing and take a look at its guts

Holy hell... this thing is crazy crowded. 12 trimmers?!?! The thing is mostly SMD save for the BBDs and a few electrolytics, and fits a ~1590B sized with a battery. There is barely a spare millimeter to be found.

And it made me curious. What is the most insanely densely populate board you've come across?

That's a tight one.  I've had the pleasure  ::) of repairing a few.  The interesting thing is that those TH parts would all have to be manually soldered by a person.  There isn't enough clearance from the SMD components for wave soldering the TH pins.

Not as dense as the Carbon Copy, but this one has a lot going on. :)

We didn't wave solder on that one either.  ;-)

FF(X) are doing an envelope filter, right? :)

(Anyone else automatically try and pick out what's going on?)

We are doing and envelope filter, but that's not it.   ;)

Is that the tremophase?

Yes, indeed.

The envelope filter will be coming out shortly...assuming no disasters in the next week or so.  ;D
