When I was in HS, I went to a tech school class: Electronics. A lot of the students went on to do soldering of electronics for military applications; so they taught us about soldering rather extensively. The instructor told us never melt solder on a joint, let it cool, and re-heat it to connect the wire. He said it causes cold solder joints. Better to use a "third hand" tool, and heat the wire and the solder together; so the rosin will properly coat the joint without getting cooked away.
The true cause of cold solder joints is movement of the two pieces being soldered while the solder solidifies. Eutectic solder helps as does ensuring the pieces don’t move as it cools. A third hand can help for sure.
@@SoundSleuth That is another cause. In this case, when the rosen gets burned off, it will work fine at first; but without that protection, over the months and years, it will oxidize faster.
I learnt you need to heat the pad first, together with the wire, THEN you apply solder.
Solder must be the last thing touching the board, so it will get sucked in by the wire into the pad hole.
I think it's way more important than rubbing the flux off.
@@giacomoneri1782 That's correct, to apply the solder last, after heating the wire and the pad. Not burning off the flux by re-heating the joint is however, essential to making solder joints last long-term. Those are referred to as "cold solder joints," and are a recurring source of failure long-term. The key idea is to complete the joint, and then not reheat it. Once it is melted, you also do not want to leave the heat on for very long, to keep the rosen from burning off, and allowing the joint to eventually oxidize. Also, it's best to wipe up the wire with the tip of the soldering iron afterwards; because if you just pull it away, it can form a peak, and solder peaks, we were told, are another source of failure long-term.
@@SoundSleuth We were taught also not to move the joint as it solidifies. I'm not 100% sure that re-heating a solder joint vs. moving the wire as it solidifies is a "cold solder joint." I am very sure we were taught both were definitely to be avoided. Eutectic solder is a new one on me. Sounds good.
wonderful, do y also sell solitaire capsules?
yes, check out the full JLI website here: www.jlielectronics.com/
I'm doing my first build from largely JLI components, this vid is a great resource, thanks!! Do you have any experience with the JLI103 capsule? I wonder how it would compare to the TSC1.
Yes I have Makes a a great mic!
@@SoundSleuth Thanks for the reply! How would you describe it compared to the TSC1?
@@badmiddens It is similar in the fact that both are center terminated. Check out the response graphs on JLI. THere is a subtle difference. The OPA circuit is extremely flat and low distortion. So you get what the capsule gives you.
finallly, yeeeeeeeeessssssssss
Great stuff as usual Jules. However, why make the same error low end mic manufacturers have done for decades? K67 with flat circuit. It's just not meant to be used in a flat circuit, and is greatest contributor to "China sound" or "harsh" atributes. That capsule has way too much going on at 10k, and it's very audible, especially with cymbals.
Actually, I am not looking at that as an error. The OPA circuit is flat as you mention. It also has really low distortion and less noise than a FET in the 10K and above range. The capsule does have that boost. You can easily EQ it in post if you are not a fan. With that said, all the drum in the video are with the Samantha and the TSB-2555B capsule.,
@@SoundSleuth in that case I'd include the typical de-emphasis curve of say u87 with the kit, so that end user can easily get there. Random eq moves in edit don't usually address the specific capsule curve adequately. Cheers! 👏
@McdowellBaptistChurch-js2pn I agree 100%, I have no issue working with k67 in a flat circuit, as I know how to address them. But in a comercial product like this what are the chances an average DIYer would know the difference between the different capsule types. I just say it would be nice to have optional switch for HF filtering, or sell the kit by default with a capsule without, or with moderate HF boost.
Great documentation and set up. Thank you! I picked up a couple and am in the process of building. The TSC-2 capsules that I received don't have the backplane wire attached (just the front and back diaphragm wires). It did include a separate (unattached) blue wire with a small eye ring that I presume is supposed to take its place. Should this wire be installed with the mounting screw (making electrical contact with the side of the capsule)?
Yes it needs be be in contact with brass part of the capsule
@@SoundSleuth Awesome 👍 thanks for the reply and support.
is there a comparison of all the kits available anywhere?
I will get some comparisons up
@@SoundSleuth Ooh thanks :3
Kit links seem to be missing.
Added them ;-)
Hi Jules, can I use the TSC-1 capsule in a Rode NT1A? Thank you. (Would love to know about the JLI-86U too).
You can use most 34 full condenser capsules. The JLI-86U is really good edge terminated one. If built four mics with them
how the inverter board get power for itself.
@aravindadas567 from the OPA board’s 12V www.jlielectronics.com/content/Full%20CondenserRev3.pdf
@SoundSleuth , where the microphone pre circuit get power?
@@aravindadas567Phantom Power from the mic preamp or mixing board. en.wikipedia.org/wiki/Phantom_power
@@SoundSleuth, through xlr cable from mixer or sound interface?
@@aravindadas567 Yes
Links aren't there! Oh nose!
Yea, It was the chicken and egg thing, They are up now. Thanks!
come on now, let's get some product up on the site, impulsive consumers have a short memory, and you want to have it available immediately after watching this. Now what was I talking about?
Yep! Im on it!
