content: Wow, this was almost painful to watch! Funny thing is that it's titled "proper" soldering technique. This should have been called "what you can get away with using half assed jacked up equipment and heavy handed techniques" Try not to laugh too hard when you see the tip of this guy's iron.

content: So the big deal is that he's not using a $300 soldering iron? Who cares anyway for such crude stuff. He even used solder wick to clean up a tab, I wouldn't even bother. He also applies fresh solder to the joint instead of using the iron as a paint brush, so he's correct on that part as well. Even shrink tube is used, I've seen plenty of stuff wrapped in electrical tape...The end result is what counts, a properly wetted soldering joint. I have used an old soldering gun with a custom made tip (from a piece of 2.5mm2 solid installation wire) to solder stuff like this. Sometimes a crude tool is all you need.

content: I'll admit that I've used rat shack soldering irons in a pinch but i sure as hell wouldn't recommend the things as a preferred tool. if you're on a seriously tight budget at least get one of those 20 dollar "consumer" 50w or whatever weller stations. and that silver solder is so much better than tin/lead. also don't forget to use an iron tip with more pits and craters than the dark side of the moon...and be sure to always store it in a coffee can!QuoteOften times they'll ground the body of a pot for shielding purposes so you don't pick up any unwanted hum when you reach down and touch the controls. however the amount of time parked the iron on the case probably damaged it in some way or another. the proper way is really to scuff the plating off, clean with IPA and apply generous amount of flux then solder the bus wire with a tip that's got a high thermal mass so you can get on it and off fast.

content: Quote from: rollatorwieltje on January 31, 2013, 09:57:04 pmI'm not saying you need a 300 dollar iron. a consumer grade station for home use would work just fine. But i do say at least use a clean properly tinned tip that's not all pitted up, covered in oxidation and burned up flux residue. His wire tinning procedure is horrific as well. he's worried about not having the iron close to the insulation but the solder runs down inside the insulation anyway. he overheats the control pot when soldering to the case. And use some liquid or paste flux. What you can get away with and what's proper, which is what he's saying his video illustrates, are two totally different things.Quotethe audiophools use silver solder to keep the werewolves away from their gear. thought everybody knew that?

content: Quote from: smashedProton on January 31, 2013, 10:09:32 pmIt depends what you are working with, doesn't it? Some components, PCBs , connectors and wires in older Tektronix oscilloscopes and other RF equipment are plated with silver. There you would use the silver bearing solder I believe (to prevent silver scavenging).Silver bearing solder is expensive compared to lead free and standard SnPb solder but I would not go as far as to say spending money on it is wasted. If you don't need it OK, no point arguingSilver bearing solder does have a lower resistance though, and has a better reliability compared to non-silver Rohs and 60/40 tin/lead solder. The reliability here is regarding thermal fatigue and mechanical strength of the joint. Note, that this is only true for solder with lead, too little is known about the impact of silver and copper in Rohs solder regarding thermal fatigue at this point.Silver is added to RoHS solder to lower the melting point and improve wetting. Silver in RoHS solder makes it more likely to fail to mechanical shocks but improve resistance to thermal fatigue (at least, better than RoHS solder without silver).I use Sn62Pb36Ag2 solder for SMD work, and also have about 2kg of 0.5mm 60/40 solder. I believe I'm biased towards the silver bearing solder.What I don't understand is, he says his solder is lead free and calls it silver solder. If it's one of those 3.5-4% silver bearing solders that melt at 180-200 °C / 400 °F, why does he have to heat his solder iron up for 20 minutes(well, that black tip says it all)EDIT: he didn't claim his solder is lead free. No idea why I thought he did.

content: Well it's not bad to advertise Sn62/Pb36/Ag2 solder, but saying that you should stay away from leaded solder in the same comment is at least an incomplete statement. If he means to not use plumber lead based solder (Pb75/Sn25), then he is correct, however if he means don't use Sn60/Pb40 or Sn63/Pb37 in favor of "silver solder" (which apprently is Sn62/Pb36/Ag2) then it's just plain stupid. They are all kinda alike since they're all lead based. He makes it sound like Radio Shack silver bearing solder is lead-free or that he's soldering with pure silver now.Also I am pretty sure that unless you're in some very very specialized field of electronics the conductivity of solder doesn't really matter, and I've never seen a corroded Sn63/Pb37 solder joint, which he claims to be the reason why "everyone" uses "silver solder" (which is another unproven claim). Sure they can corrode under extreme conditions and over time, but does silver really fight that effect? Not convinced.Pretty sure that before ROHS became mandatory for electronics manufacturers that they mostly used lead based mainstream solder like Sn60/Pb40 and Sn63/Pb37 mostly unless they had a very specific reason to not use them (joint strength, silver scavanging). It doesn't make sense from a price point of view to use a rare metal and increase the cost of your product. Oh he also claims that price for whatever stuff might halve if they used lead based solder. Yeah right.

I now understand some of the processes that are involved with makeing analog signals into pleasing noises. That said for a fella that just just wants to put a new pot in his axe....this would work. Should a person go out and buy a 300 $ soldering station to weld 1 component? The guy made a bunch of mistakes but hell he give it a shot.

content: There's a fairly big difference between welding and soldering/brazing. Soldering/brazing are somewhat similar as you're not really melting the base material of the two parts in question (I definitely don't want to be melting my IC leads to a PCB board). As far as I can understand the distinction between these two is a bit fuzzy and is somewhat defined by temperature, but then again I don't really have a solid understanding of the brazing process.Welding on the other hand requires sufficient penetration in the base material of both parts in order to form a proper joint. It's possible to get parts to somewhat stick together using only filler materials, but you'll have a terrible joint which has very little mechanical strength compared to a proper weld. In certain circumstances it's possible to get a fantastic weld without using any extra filler material.
