Which PCB fab do you currently like the best?


  • Hero Member

    I've been using JLCPCB for the last several PCB fabrications. I've pretty much convinced myself that on Sundays they may continue progressing work that's already in progress, but nothing new seems to start until sometime later on Monday. i.e. there's no apparent advantage to submitting new work on Sunday (China time). Also, it seems to inevitably take 2 days to fabricate, but even if finished early on the second day, nothing gets truly shipped until late on day 3 at the earliest.

    Since the quality seems about the same with all of the fabs, the main differentiators these days boils down to price and speed. Are there any fabs with faster turnarounds than this that anyone here likes to use?



  • Pcbway do produce better finished pcb, but the big advantage of jlc is their SMT service

    How is it better? Aside from the quality of silkscreen, which I have noticed varies from one vendor to another, what should I be looking for?



  • @NeverDie Just for clarification, you are not asking about assembly, right?

    What a great thread (inquiry).

    I've relied on OSH Park for PCB manufacturing. Never have I found a mistake that was not of my own making. But for assembly, I'm really impressed with my one JLCPCB experience - and the parts availability (LCSC, I think). Their online CAD program (EasyEDA, I recall), was a small hurdle but easy enough.

    Right.

    If/When I advance to the point of designing the RF chips directly onto a PCB instead of relying on RF modules, the assembly feature would probably pay for itself. I'm not quite there yet, but maybe later this year. LCSC has nRFx chips, whereas a lot of the desirable nRF52x modules just aren't available anywhere. So, if I can't buy, maybe the answer is build from scratch!

    Fortunately, there is one advanced project that could maybe serve as a pathfinder:
    https://www.openhardware.io/view/742/rayBeacon-nRF52-on-the-go-Development-Kit
    but I don't see where he has an antenna built into the PCB. I'll have to inquire with the author about that.

    Another thing I've noticed about JLCPCB is that if each item in my order is just the minimum quantity 5, the whole order seems to get fabricated in about a day. If any item is higher than quantity 5, then it seems to get kicked into a slower queue. I don't have extensive datapoints to say definitively, but so far that seem to be the pattern.


  • Hero Member

    Well, maybe PCBway really is better. I was about to place an order with JLCPCB, but they said production wouldn't start until Monday, whereas PCBWAY said they would be finished in 24 hours. Then again, even though they say the "processing time" is 24 hours, now that I've placed the order, they're saying that the estimate finish time is on Monday, August 8. Huh? That's more like 48 hours. Hopefully by "finish" they mean shipping on Monday.

    Well, you could play the game of ordering 4 separate orders if you wanted 20 boards. Seems silly... but if that is their system.... I always enjoy the minimum order so I can find my errors, then order the updates, and find my errors, then order the updates. Life is itterative.... until it isn't. What a blessing to have so much technology at such a little price. If you make a mistake you lose a little and remember the error.



  • How is the shipping time vs cost for JLCPCB and PCBway?
    I'm in the US and just ordering small prototype numbers, so OshPark works well for me. But I am thinking of a larger qty order at some point.

    @nagelc With JLCPCB, if I place an order on Monday morning (china time), I can receive it by Friday afternoon (US time) if I select DHL, which costs around $21 for the shipping. Shipping cost is a little higher with Pcbway, but build cost for multiple copies of the same board is lower at the margin with Pcbway, which I hope may be a day or two faster on turnaround. We'll see. According to their tracking, they're now 18% of the way done with their 24 hour processing claim, so they'll have to hustle if they're going to get it to 100% done in about another 12 hours. So far, the main difference is that it's the weekend, and Pcbway is at least doing something to progress a new order, whereas JLCPCB would be waiting until Monday to even start.

    @Larson It turned out that in the end it didn't matter. Despite their estimates, it still took them 2 days to build. With JLCPCB, the patterns has been 2 days of build time and then ship on day 3 or 4, but usually day 3. There seems to be considerable lag between them finishing production and them shipping it out. Fortunately, once DHL gets it, delivery is very fast, usually in 2 days, including weekend days. I've had no complaints about quality, so that's why here I'm mainly focused on speed, because it's important for keeping momentum going vs. a project stalling out for want of a nail, as it were.

    It's really quite amazing. I used Pcbway back in 2017 to build 10 pieces of my coincell sensor PCB:
    https://www.openhardware.io/view/510/Multi-Sensor-TempHumidityPIR-LeakMagnetLightAccel

    At the time, it cost me $38 at PCBway, plus shipping, to have them fabbed. Now I could probably get 30 of the same PCB from PCBway for $5. Plus, pcbway has kept the zip file, so if I had misplaced it, I could either download it or just hit the re-order button. Nice! Shipping costs are a little more now than then, but you get the picture. Prices have gotten so low that the PCB fab price is almost trivial, and I fab all kinds of breakout boards and add them to the orders because it's just so cheap to do so now, and they can piggyback on the shipping cost, which often doesn't go up for the incremental baggage.

    Meh, 24 hours later after submitting the files, PCBway is still only 56% complete on its production, but that still places them ahead of the 0% complete that JLCPCB would be if I had ordered by JLCPCB instead over the weekend.


  • Hero Member

    OK, PCBway finished its fabrication. I've got this figured out now. PCBway, and probably the others as well, don't start the clock ticking when you submit your files and make payment. Instead, they start the clock ticking whenever the job gets to the MI stage of production. So, in that technical sense, PCBway made good on its 24 hour production advertisement. There's no apparent limit though on how long the job spends in either engineering pre-production, nor in how long it takes to ship the PCB's after the build is complete. The fab's don't seem to make any promises with regards to either of those, but either/both can stretch out the turnaround time. That said, it appears PCBway may be generally faster than JLCPCB, and definitely faster in tackling new orders submitted over the weekend. For those reasons, I think I'll be using PCBway going forward.
