I haven't smelled the smell of soldering in years. But as soon there was smoke shown in the video it hit my brain with that lovely smell of my childhood.
+Marc Kamer Happy to tickle your olfactory memory this AM!
cool..
very good for the health also ....
Absolutely correct. The flux and heat allow for solder to wick up the legs of the components.
I did this for a few years , small place up near Ottawa
do you clip the legs of the components before sending it through the machine? I was very surprised to see no long leads on the bottom of the board at the end of the video
Yes, we send them through a machine that clips the leads.
1:44 Any burnt motherboard after all that smoke?
chips on the underside of the board would be after-solder.
great video,
how much pre heat temp you are maintaining and also bath temp?
we are largest manufacturer of solders in India.
I have absolutely no idea how wave soldering works. But would I be correct to guess that The first white foamy liquid it passes through is flux, then it goes into an oven, then passes through molten solder?
You got it!
how often do you clean your solder bath to remove solder dross?
+Adam Joseph Mariñas We clean the solder bath after every use. Additionally, after every 6 months, we take a Coke can and cut it down, dip it down into the molten solder, then let hit harden. Once hard, we peel the can off and send the hardened sample out for analyzing.
How is it controlled so well that a solder millimeters can be done without the whole board being splashed by molten solder?
It is, but solder only sticks to, or "wets" certain things. It hits the board, but doesn't stick to it so it just falls off.
It is the chemical reaction with the flux, heat, and rate at which the solder is flowing in a wave. The legs graze the solder and it wicks up the lead, through the hole. It is a clean process.
Also because they apply a coating of "solder mask" during manufacturing that prevents solder to sticking to the pcb anywhere that is covered in the stuff www.tempoautomation.com/blog/understanding-soldering-part-5-solder-mask-application-process/
Sorry to be a bit thick, but I followed your explanation of this wave solder process and didn't fully understand it so I just watched another video of it on youtube. It would appear that if the legs of the ICs are to be soldered then the board would have to be upside down and the whole chip submerged in solder. Surely that's not right. What did I miss here?
The IC sits on top of the board. The legs are through the holes. The legs drag across the flux and the wave of solder. The board is between all of the action. The IC is safe.
can i know why is it at an angled position, what is the purpose??
+Yee Ting there is no particular reason. Just happened to take a quick camera phone video with no cinematic theme. Just a video. Thanks for watching.
how component be fitted exactly during process?
+Neel Jayswal so sorry we are just seeing this. There was no notification. To answer your question, components are checked before they are sent through the wave. The board is slowly drawn through and the parts do not move.
How do you set it so it solders the correct parts?
We can raise and lower the board to only coat the legs of the components.
Can I know what is the substance in the liquid? Is it tin or lead?
Probably unleaded. Leaded solder is a bit of a commercial nono due to health concerns
63/37(sn/pb)
some time 99.3/0.7(sn/cu)
This may seem unrelated, but does anyone know if NASA build's their own pcbs and has their own wave soldering machines or if they send it to third party companies like this one?
Smoooth. I'm pretty sure NASA doesn't make anything. They're a government CUSTOMER to aerospace companies, which, I'd have to say the majority of even them don't build their own PCBs, they subcontract out to companies that specialize in the fab of PCBs, others that specialize in assembly, etc. Depending on factors which also may include security issues. Now they may do some IR&D with some small fab there, but I'm pretty sure they don't manufacture anything, they contract out.
Not sure.
The reflow soldering process is a little bit different than wave soldering, but it’s the most common way to attach surface mount components to a circuit board.Details pls see my blog makerfab.blogspot.com/2018/12/why-use-reflow-soldering-in-pcb-assembly.html

what kind of witchcraft is this_?
We call it science and technology :)
Skip to 1:23
this only works for crude boards afaik. only large parts and through hole. no good
We also have surface mount and a lead-free machine for other types of PCBs.
No.1 reason electronics fail. poor solder joints. I don't know if i like this technology. Seems to introduce lots of defects.
No defects. We do a 100% visual inspection. Low rejection rate.
@@electrosoftincpa 100%? and continue the rejection?, did you know about Six sigma?
@@hectorvalle2443 We are a custom manufacturer - low volume/high variation. Rejections are built-in to the process. Six sigma makes sense in organizations that have high volume/low variation.
Why did this remind me of Planned Parent Hood harvesting baby parts.
+MavHunter20XX Not sure. That is pretty disturbing. We will pray for you.

Don't pray for me, pray for the potential mothers that gave up their unborn child to be sold at a profit for a genocidal company.
