PCB prototyping with UV solder-mask. High precision PCB double-sided. Chips QFN36 and ATMEGA 328P-AU

Welcome to my channel! In today's comprehensive video, I will show you the optimal process of manufacturing a printed circuit board (PCB) using a prototyping machine. Whether you're interested in homemade PCB prototyping or professional PCB manufacturing, this video will guide you step by step through the entire process.
Firstly, we will delve into the PCB design phase. I'll demonstrate how to prepare the PCB design using popular software and provide key tips for ensuring your design is easily processed by the PCB prototyping machine.
Next, we will focus on the setup of the CNC milling machine specifically designed for PCB production. I'll explain how to properly connect the tool, calibrate the axes, and select the optimal parameters for milling the PCB. You'll find my instructions straightforward and easy to follow.
Once the machine is ready, we'll move on to the actual PCB fabrication process. I'll guide you through the steps of preparing the board, applying the necessary layers, and performing the required milling operations. You'll learn techniques for achieving high precision and quality in your homemade PCB.
Towards the end of the video, we'll cover quality control and final adjustments. I'll show you how to conduct a thorough inspection of the manufactured PCB, address any potential errors, and apply protective coatings for long-term durability.
Whether you're interested in milling double-layer PCBs or want to explore the possibilities of professional CNC engraving machines, this video has got you covered.

I was thinking about getting one but the price is quite prohibitive. The drill bits are specific or can be replaced?

[@andreapiccini23]

@@GuilhermeGomes2 can be replaced with anyone you want, if i remember correctly, spindle diameter is 3.75mm , any drill compatible with this size would be ok. Price is high but i assure you that with a normal CNC lost time to set it up is much longer! At the same time is convenient if you have a company or work for/on it and you need fast prototyping, if not, a normal CNC like 3018 (200€) , with fine tuning, can reach the same results ..

[@javids6656]

It seems impossible to me that the Z axis is perfect, it always has the same depth, this is one of the problems I have always had on my CNC. The trick of the spring to remove the mask is very ingenious. The video is totally addictive.

[@diegomestrecam7674]

you can create a depth grid of your PCB so that even if its not perfectly flat, the Z-axis will compensate the error and stay relativly flat to the PCB But yes the accuracy of his cut depth is really stable

[@MHdeJong87]

Does anyone know how this works with the spring? I also noticed it. Is the engraving bit just loose in the holder, with the spring on top of it?

[@mensaswede4028]

Even if the Z-axis can be held accurately, I feel the best way to remove the solder mask from pads is with a laser. But then you need to invest in a laser….

[@AhmedAbdo-cj2ms]

Good job 👌 but a music come sleep ☺️

[@jonathanseagraves8140]

That build plate is overexposed for a reason. They are hiding the damage that will be inevitable from trimming the board. Also, ask yourself why you never see the surface finish of the copper after the solder mask is etched all in one take. (they aren't even blowing the debris away with the air nozzle you can see in the shot) They have meticulously finished each pad by hand to give it an unrealistically smooth surface finish. Resetting that board on the build plate (not to mention leveling it) would be a right pain in the ass. Also, you cant hear it... fucker will be loud.

[@nxtktube]

30-50W fiber laser should do a better job i think

[@chubbchubbist]

The build plate is untouched. you usually use a 'sacrificial' board on any cnc that can be easily replaced. They have a video of the copper after the solder mask is machined off by the cnc, it's not super clean but it looks much smoother and has a much better finish after tinning, as they show above. When putting the board back on for secondary machining, you don't autolevel again, you use the same profile as when you did the primary machining, the board hasn't gone through any process to warp its profile so it will have the same profile as before. The motor has a whining sound, but you can quite easily have a conversation right next to it without straining,

[@eduardflorea9823]

I'm sold.... ordering a machine for sure...

[@VladimirMilyaev]

Beautiful, complex, amazing. I tried to use milling for valve designs and bumped into parasite capacitance. It was solved by splitting of solid areas into smaller pieces.

[@Mrm0nG0]

Very nice, but what was the thickness of the copper clad?

[@arashghasemi]

The only problem with this milling technology is that the remaining copper chunks between the actual routes become capacitor and indicator at higher frequencies. These unwanted capacitors and indicators become completely unacceptable and the circuit response will be totally wrong. Other than this issue, if you want to implement a design at low frequency, it's perfect imop

[@leonardosabino2002]

This is only a problem for sensitive circuits like RF (radio frequency) and capacitive touch sense. For 98% of circuits, leaving the extra copper in the board makes no difference.

[@coltennabers634]

You can mill away the extra copper also - though it will not look as nice

[@arashghasemi]

@@coltennabers634 yes I cut the extra copper. But it's very time consuming and not worth it

[@TheoPur]

They could have also tried to stitch the floating copper to ground using vias but considering they had to rivet each via it would be time consuming. I am not even sure if they had a ground plane on the back side and if they did they cut it up too much with all the plane hops/traces on the back. Notice how they ended up having to tilt the RF module off the board even though there was a cutout for the pcb antenna. That board is probably producing a lot of EMI considering all the floating copper that is around like you mentioned. You could argue it doesn’t matter for digital or low speed circuits but with rise times decreasing and they wanted to put an RF module with pcb antenna, they should have followed more signal integrity guidelines when doing the layout.

Sometimes doing it by hand or in a small scale like this has no other reason other than to show how it can be made, the charm of it and it may just nip that itch OP has felt when working on their own projects. I find this to be really beautiful and inspiring and its fine if thats all it will ever be. Its obviously a functional board and i dont think il ever do it myself but still.

[@kingsmod8777]

[@liveen]

Why though tbh? hes doing a decent enough job with the dispensing on his own, why spend the money on that part when he doesnt need to? someone like GreatScott however would benefit from a stencil, and some flux, and a more humble attitude, and more knowledge, and uh, a lot tbh. i dont like greatscott

[@pentachronic]

@@liveen Agree about greatscott. I find him annoyingly arrogant. The reason I say to mill a stencil is that he has the machine. I photochemically make mine. Works well enough but in all honesty I now just buy them with my PCBs as it's cheaper and they are laser accurate.
