Thank you very much for the comparison and your comments about cleaning! I didn't even consider the cleaning aspect so far to be honest. Very helpful!
Great video, as usual, Steve! Looking forward to seeing more of those LED boards.
Yes, I had some boards from jlcpcb with wired texture last year too. However, the more matte boards needed more heat when reflowing.. i think this is better now.
In my opinion, you deserve much more attention and subscribers because you are providing all of those useful information for free! It's your nice and honorable personality which lets me enjoy every vid! Thanks a lot for doing this!
Sounds like someone wants an ultrasonic cleaner. Useful video thanks!
I use both JLCPC and PCBWay. For cheap prototypes and stuff customers are not going to see, use JLCPCB. If I want a good looking board to show a customer, it’s PCBWay.
My biggest gripe with JLCPCB is their Fr4 boards have writing on them that shows once the board is finished. Also, the printing scratch’s off easily. The black matt from PCBWay seems to take the silkscreen better and I have not had any issues with it.
Just my take, others may have different experiences.
What is this text you're referring to? Something on the raw board material that shows through the solder mask? I've never seen that on the boards I've ordered from there.
Can't say I've seen this. Do you mean someone actually wrote on the boards?
@@sdgelectronics No, i think it is a brand mark on the FR4. When the unwanted copper is etched away, it becomes visible even through the solder mask. It is a NP like joined together.
Useful comparison. Thanks
JLC changed it around mid 2019, they used to offer gloss or matte black but half way through one of my orders they changed it to this silk type black! And it just became "black" in the order menu, I quite like it, marks less easily.
Yes I think they've got it just right in the PCB featured in this video.
I order almost weekly stuff from JLC. Sometimes is silkscreening is from lower quality. But never had big problems.
I guess its Matte or Satin ?...I prefer the cleanable black.cheers!
PCBWay do offer a gloss black if you're into shiny black.
This is a very interesting information. I am about to order matte black PCB's and It never occurred to me that there can be a difficulty in cleaning... Hımmm...
Curious you found the PCBWay black to be hard to get 100% clean, I've been having the same issues with their Blue PCBs.
As I bought an Ultrasonic cleaner anyway, I tried using that, it works.
Hmmm... I did a few black custom Arduino shields 3-4 years back with PCBWay and they were really really glossy and I didn't have any issues remove any flux after manual soldering.
I would say PCBW matt, JLC satin finish.
With my Deoxit flux I have to kero first, IPL, then strong surface spray detergent, to get the waxiness off it.
Until such time as either manufacturer changes the type of black you get :P
I remember a while ago Seon from Unexpected Maker had issues tryna clean the black PCBs from JLC cause they were so impossibly mat. I expect the surface finish is slightly porous so it absorbs the flux/cleaning residue
Seon found recently JLCPCB changed the black yet again.
I've gotten two different shades of Green PCBs from PCBWay, but otherwise they seem consistent.
asking the important questions
Can you maybe make a video about how you started learning about electronics and what you did to improve
Nice, thanks for comparing, Does PCBWay surprise you with a customs duty invoice a month after you received your boards like JLCPCB does, or do you pay them right off the bat at the time of order? it is really annoying that JLC does not include this in the cost of the shipping.
JLCPCB offer two DDP shipping options which means all duty is paid at checkout. PCBWay don't offer this yet unless you have a FedEx or DHL account
Well, that's different lol See I'm in Canada and I have never seen such an option and I always use FedEx, and about a month after my boards come in I get an imported invoice, and i don't even have an account with FedEx it's just what is easier to deal with.
Thanks for the comparison! I've seen issues on matte soldermask with the silkscreen crumbling off, usually pretty evident with a fingernail scratch. Out of interest have you seen that from either of these suppliers? Would like to use some matte black boads for front panels so it would be nice to get some tough silkscreening!
Silkscreen is really good on both of these. Even with scrubbing and various alcohol cleaners, I've never seen this in any of the PCBs I've had from either supplier.
@@sdgelectronics Cool, thank you. Will have to give them a try then!
I have used many PCB manufacturers over the years but found JLCPCB to be best on quality and price for my needs.
Any difference in cleaning performance using flux remover instead of simple IPA? Modern fluxes just aren’t fully soluble in IPA.
I rarely use IPA, it's normally fluxclene. I expect similar results with any solvent though
@@sdgelectronics I like Fluxclene myself. Results vary _significantly_ by solvent: IPA won't fully dissolve many no-clean fluxes, leaving behind white mess. (Hence why flux removers are blends of solvents.)
Great video. I didn't know the black is matte. Wonder, what's the reason it is not as glossy as green or blue?
For JLCPCB it was by popular demand. PCBWay still offer a gloss black option
not sure about pcbway but I remember jlcpcb not wanting to do assembly on anything but green pcbs. might be a point of interest for some
Announcement in the next video ;)
They could add options for mat and glossy, many people would probably appreciate.
PCB manufacturers read this pls.
First :P thanks for another good video, do you find that Pcbway is more money than JLCPCB ?
It depends on which options you choose. The 4 layer PCBs for the LED driver PCBs in the last video were quite a lot (2x) more expensive than from JLCPCB though.
@@sdgelectronics I just did a test with pcbway and jlcpcb, i find jlcpcb 1/2 the price for 2 layer 100x100 boards.. I'll stick with jlcpcb for now. :P keep up the good videos !
One of the suppliers did a terrible job seeing how different those PCBs are..
Good eye sir.
Yeah, I’m pretty sure that he was so dumped about different color that he didn’t noticed but look at this SDG logo crooked 90 degrees... geez
Add in "Next Pcb" black pcb also
I was surprised to find that the shininess of PCB is actually a factor in any decision for which one to go for. In fact, it's not even abt shininess. It's gone to the level of which is less or more matt. What.. LOL. I guess non-beggars can be choosers. Besides, the pads on one of the boards are consistently non-consistent in size. That should be the point of any comparison IMO.
Hi. With JLCPCB I had a quality issue with noticeable imperfections in the black solder mask layer, as if the coating has thickened unevenly on the surface: i.imgur.com/k84Ox2q.jpg - They said it's a known problem in the "exposure process" for black boards, and that they can't make sure it won't happen again... Have you ever experienced this issue?
Hi,
JLCPCB has informed me that they don't do buried or blind vias!
Thus, my order was cancelled.
Did they do buried, or blind vias for you?
Would greatly appreciate your feedback.
Sadly not supported by them at the moment. You'd need to look at one of the other suppliers
Well , have you ever used other Chinese PCB manufacturers than PCB Way and JLC PCB ?
I used to use Elecrow and Allpcb regularly as well as local suppliers
I use JLCPCB for prototypes as it's cheaper and PCBWay for the final prints as they're a bit more higher quality.
The delivery of JLCPCB is twice the price of the board which spoils somehow anything about low price pcb board.
PCBwayyyyyy
Wow... that was a waste of 3 months. They kept blaming my gerbers! They finally admitted it. But still... 3 months wasted going back and forth, trying new and different files, asking forums about rs274x, and KiCad, and thinking it was MY fault. What a waste of time.
What had happened?
I don't want to waste anymore time talking about it. You should see my order list. One after another of "failed audits. Please resend gerbers". Other boardhouses read my gerbers just fine. JLC just kept saying, "Failed Audit".
If you're a boardhouse and you don't do vias.... you better hang it up. You should at least have the common courtesy to put it on your site, "Apologies, even though we are a PCB manufacturer, we don't do vias."
How the he11 are you supposed to do a 4 layer board..... which they advertise... if you don't do blind or buried vias!?!??!
Pcbway is very expensive 😢
Jlcpcb have best prices ❤
Not anymore. JLCPCB went YUCK matte again - my last boards look like crap (last week) - not only is it a grey-ish matte black again, but it's coverage is terrible. I can see copper through many areas of it. REALLY SHIT. Super disappointing.
I am wondering whether it comes down to what factory the PCBs are manufactured in: if I am not mistaken they have 3 or 4 different factories where PCBs are produced.
I'm surprised actually, I've not had any boards that look like that. The worst I get is what looks like roller marks on the boards but it's normally pretty opaque.
@@EnricoConca You could be right. Yes, depending on the options you've selected it'll go to a different factory.
Never had that and I've had a few boards from them, they always look great.
Lovely 😍💋 💝💖❤️
Good. I wait for love from you 💝💖
Jlcpcb is the worst, if you ask any request like change in ship address they will start asking money from you.
Worst
careful with jlcpcb. My bank account was hacked from using jlcpcb. They stole over 500$ from me. chances are that they are stealing your pcb designs as well. DO NOT TRUST CHINA!!!
Good. I wait for love from you 💝💖
At least buy me dinner, and then we'll talk. Paypal link on my profile page.
@@sdgelectronics in the last months I've seen a lot of spam accounts like this in a lot of channels, do you prefer we report them to RUclips or leave them for the possible engagement?
A lot of them get past the RUclips spam algorithm by putting a random timestamp and some symbols.
@@Gengh13 Feel free to report them. I can block them, but it doesn't do anything to stop them posting on any other channel.
