Stuff you wanted to know but were afraid to ask

How do you populate your pcbs. I know shortest parts come first but I’m asking do you fold both legs over to hold them in place and solder, populate and snip the legs then solder using putty or something to hold them in place? Some other way? I ask because I’ve been using the folded legs method and have a really tough time getting something out once it’s been soldered.

everyone is likely different but I use a pcb holder so I can spin the board from from to back when needed. I solder everything one component at a time...lightly bend legs so they don't immediately fall out,, I hold with my finger and solder from the back of the board then clips the legs begore going to next part.... I hate having to fish around a sea of leads to solder up a board.

I don't know if my technique is the most kosher or not, but....

I pretty much do all my building on something like a silicone mat or neoprene mousepad.
for all the smaller/"shorter" components like resistors, diodes, IC sockets, small caps, etc I just put them thru the pcb and flip it over onto the mat... the weight of the pcb itself is steady enough to hold them in place while I solder.

for taller components I kind of do the same thing really. Except they are more liable to get crooked or off center, so basically I just give it a tiny tack of solder on one leg - just enough to keep it from falling out when I flip it over. Then I push the other leg all the way down to where I want it positioned and solder that one all away, then go back and reheat the "tack soldered" joint and put the leg all the way through as it needs to be and solder it fully down.

I don't really like having a bunch of unclipped leads sticking up as I'm trying to populate so tbh I usually am trimming leads after every 2-3 components. And I don't really care for using stuff like blue tack, and really don't care to do the folded-legs method for the reasons you mentioned

Like I said, i dunno if that's the most proper way, but it works for me

Again, everyone is different but...
Populating all axial components and soldering from the component side of the board sped up my building a good bit and no chance of loosing components. You do need good clean technique and the right tip. You can be hanging out for 5 seconds. I'll contact just the pad for a second then bridge the iron between the pad and component before applying solder. In and out in 2 seconds.
Since your fillet is on top, as long as you use the correct amount of solder, you get a much smoother finish to the bottom. A much better alternative to cutting through your joints. It is a little more of a pain to clean flux, if you desire to do so, and depending on the solder you use.
I'll then do film caps in 2-4 passes with blutak, depending on the size of the board and number of caps. I'll tack on side of each cap, then flip and check alignment.
 
What would be the downside of building a relay system with a 5v reg, a cap and 1meg or so to ground and a 5v relay only?
It seems like that's all one would need. Forget all the switching. Just switch the control line to the relay.
I suppose you could get some relay chatter?

I usually bend both leads to secure the part (like in @Erik S's picture). But after 1 side is soldered I straighten the other lead before soldering--that way at least one is easy to remove.

I like to do this too. I’ll add most or all the resistors, do a pass on one side, straighten them all out, and then do the other side. I used to do them one at a time, but after I had more practice and a better iron it’s just so much faster to solder a whole bunch of components in one go.

Thread 'Basic Workflow Tips for Building a PedalPCB'

Hello! This is my method for building a PedalPCB from start to finish. Is it the right way? Not necessarily. It's just what works for me and I hope it sheds some light on certain steps in the process along the way. I created this as a reference guide for anyone to use if needed. Thanks for reading!

Step 1: Drill the enclosure.
I recommend having this done before starting any soldering as it makes test fitting the fully populated board a whole lot easier later.

*Key step* Always print the drill template at 100%. Some printers default to "fit to page". You...

I'm sure most would say I populate like a 🤡 so I'll spare you my own take on the above tutorial
