First I2S Audio Shields using my latest vacuum design
Вставка
- Опубліковано 6 жов 2024
- It's time to check if my latest vacuum stencil bed design is any good - so I decided to do build my first production panel of my rI2S Audio Shield, and capture the entire process n video for you all.
Fingers crossed ti all works ok!

Some PnP have a gripper nozzle for grabbing such parts. It fits on where the nozzles do and is a gripper with 2 fingers to grab the sides.
you can 3d print such a nozzle using something like tpu
Thanks for sharing the whole process and not just the new vacuum ... impressive, to say the least!
When the side of the board smeared because of the lack of vacuum(or because the vacuum sucked the paste), I thought to myself "There always HAS to be something left to fix, no matter how hard you try- that; drives my nuts!"
Seon -- nice job! A very satisfying result. And I'm sure I'm not the only one who appreciates your various parenthetical observations along the way.
Cheers Graham :)
Your paste alignment and edging is super clean. Elegant solution.
always somehow relaxing to watch the pnp. nice success, congrats
I tend to set up my stencil print with a small gap between the stencil and the PWB. This is on an automated stencil printer though. But the reasoning is that when you squeegee, you press the stencil to the board and then the stencil will release itself from the board instead of me forcing them apart by lifting the stencil.
Amazing work. Good to see an idea completed and it actually working and improving your quality! Well done matey!!
Cheers mate! I hope you and the family are all well!
That's some tidy solder masking!! Noice work!
great video and nice to see the whole process, thanks :-)
Looks great!
To the switch
Nozzle for inspiration see User manual for K1830 page 49, last picture. Different shapes are made to order. But the question is whether the K1830 can first align the nozzle over the camera, then grab the part and align it again over the camera. Then there are rectangular nozzles with positioning by means of a protruding pin. But that's probably handled by other machines.
Nope, the K1830 cannot pre capture the nozzle position.
Hey Seon, could you post more PnP videos? Watching your machine work is like ASMR and it's hard to find videos that are longer than just a few minutes or short demos of machines. Would be kind of nice to watch like 10-20 minutes of uninterrupted PnP manufacturing and maybe a shot of the whole board going through your entire line.
Like the vacuum ideal. Trying it on mine this weekend. I have a switch like yours, Mine PNP will place it, just slow the travel speed down some.
I ran that switch on a different board, on it's own, at 15% travel speed - got 40% correct placement :(
@@UnexpectedMaker Man, the PNP Gods really must hate you.
@@UnexpectedMaker Is there a "Big Gulp" nozzle that might suck the entire face of the switch?
There might be a custom nozzle I can get for the N8 for the switch - I'd need to look into it.
Added the vacuum mod to my stenciled printer. Worked very well with the frameless stencil I have.
@UnexpectedMaker your jig setup looks amazing.
what is the vacuum pressure your using to hold the pcb?
Nice process, thanks for showing it.
I find the vacuum cleaner sound obnoxious and wonder if you’ve seen the small Venturi vacuum generators that plug into compressed air feeds and produce a vacuum.
You can get them pretty cheap from RS.
It’s still not silent- substituting an air-flow hiss for the whining motor, but might be worth looking into?
Venturi pumps cant produce even 20% of the vacuum I need to suck a framed stencil down, It's not what they are designed for. The idea behind this project is for it to be as DIY as possible. Everyone has a vacuum cleaner or access to one. Most don't have an air compressor, and spending $ on Venturi or similar solutions makes it quite expensive.
Nice !....cheers.
A good fun video.
When using your manual stencil, do you cover everything in a single pass? Do you have a video of you stenciling boards using this? Thanks
Stencilling should always be 1 swipe only - Any time you swipe multiple times, you run the risk of pushing paste under the stencil.
@@UnexpectedMaker thank you
Will you be the files being available for us to modify? I would be totally fine to purchase it from your store.
A 505 will pick up that switch just fine.
I have the same neoden stencil printer, how do I setup the rest of the jig?
Can you sell the rest as a kit?
Not planning on making kits, sorry. I might release y design files in the future, at least for the base section, but they'd need a lot fo cleaning up first plus converted to parametric design.
@@UnexpectedMaker thank you. I would appreciate that!
Did you succeed in using these parts systematically?
Would you still recommend this method now, one year later?
Also can you share the files with your followers? And have you made any improvements to the parts since publishing this video?
Cheers!
Sorry, using which parts systematically? Do you mean the vacuum bed system? If so, check this video out: ua-cam.com/video/5iX61nD94cg/v-deo.html
@@UnexpectedMaker thanks mate, that's what I need :) might ask a few more questions in the other thread. Appreciate it, keep up the amazing content.
Is the placement of the speaker outputs a problem? When the shield is directly on top of the tinyPICO, they touch the micro-usb. Thoughts?
What do mean by directly on top? Male headers on the I2S Audio shield going into female headers on the TinyPICO gives stacks of room, like 5mm clearance rom the USB-C connector.
@@UnexpectedMaker ah, I see. I'm using this in a compact device so I'm using one pair of male headers to connect the two.
That stencil bed thing really sucks. And I'd say that it is more than promising. Nicely done.
Cheers mate!
