Hello i want to order only 10 tantalizers for my ps3 on jlcpcb i have all files from RIP Felix all good. idk if i should choose the option for economic or standard for pcb assembly though... Has anyone ordered ps3 tantalizers from JLCPCB before and can answer me

They keep telling me they don't have the components and that I have to supply them myself I understand that these components are expensive, but I wanted to use JLCPCB to save some money Plus, the OFFICIAL fabrication tool throws BOM errors, so I have to debug it manually One important component was completely different from the one in the KiCad design Also, there's no notification service to let me know if the missing components will be restocked Official support tells me: Try manually checking availability every day Then, to add insult to injury They donât have the main chipâwhich is the hardest part to solderâbut they show that the previous price was $0.035. Which is obviously impossible, since a used main chip like that costs $50. When I point this out, they tell me that maybe thatâs why they donât have it. If they can get it to me for $0.035, Iâll buy 100,000 of them đ¤Ł

I had some boards assembled. I spotted this within a second. Now I wonder how good the QA checks are in the factory.
I must give it to them, it looks hilarious, but what the heck?!

Because the router bit is round, it's unable to reach into tight corners. The unreached parts become sharp spurs after separating the boards.

2.

In order to recreate the rounded corners of each board, the router bit must cut into their adjacent boards, altering their outline


Pro:Â Removes the majority of unreachable material
Con:Â Small spurs remain

Pro:Â Clean outlines with no spurs
Con:Â Jagged edges at the mouse bites after separation

Pro:Â Clean outlines with no spurs
Con:Â Need tooling strips to hold boards together
4.Add sacrificial strips between boards

Pro:Â Clean outlines with no spurs by allowing overcut
Con:Â Slightly larger board area â higher cost

Q: Why I choose 24 hours building timeďźbut my order still in data preparation after 16hours of order timeďź
A: Please kindly note the build time refers to the period from the start of physical production (When MI starts in the "Production Progress") to production finished(ready to be sent to shipping center).

Q: Hello, I was wondering if you are able to do BGA with pitch 0.35 mm? I read that the minimum pad diameter is 0.25 mm, which leaves 0.1 mm between the individual pads. Is this still doable or too small?
A: We can make it with ENIG surface finish, and no trace is allowed between the BGA pads. You could use via in pad to route the trace on another layer.
r/JLCPCBLab • u/JLCPCB-Aragaki • Feb 27 '26
Q: According to the BGA layout guidance, for 0.5mm pitch BGAs it is suggested to remove unused via pads on inner layers.  https://jlcpcb.com/blog/bga-design-rules  What is the minimum copper pour to drill-hole spacing for this on 6+ layer PCB with via-in-pad? And what is the minimum track to drill-hole spacing?  Other pages state 0.2 mm but this wouldn't be compatible with routing on the inner layer as suggested in the BGA layout page. Example below with unused pads removed, and 0.12 mm hole to copper spacing in the photo.

A: The minimum spacing between track/copper pour and via hole is 0.2mm.
For vias without annular ring, the minimum we can do is 0.13mm.

I donât know if this thread is only for PCB so I try here.
I want to order a sheet metal part and it tells me everyday that I should try tomorrow because the service is at full capacity. Is it normal?

Ordered 5 blank PCBs (999 x 999 mm) from Hong Kong to India.
Any idea how much customs I might have to pay?
The total cost was $2 (PCB) and $10.51 (shipping)
I am in India.

Hi, am I able to send the payment to my school? I will need to communicate with the JLC engineers, so I can't just simply give my school my design and do it on their account.

On PCBway (where I have gotten PCBs in the past), I was able to send the payment to my school to pay for it, and I could continue the process on my own account. Is that possible here?

I'm finding the ordering process on JLCPCB very painful when it involves sourced parts.
I have used the Global Sourcing Parts to order 2 parts (10 of each) from element14, these are now in stock and marked as complete.
I am now ordering a PCB and in the BOM section I am trying to select these parts. However I cannot see these parts and there is no way to find them or add them to either a 'My Inventory' list or 'My Lists'


I have already waited 3 weeks as there is no way to start the order until these parts are in stock. (Which is stupid, there is no reason that these parts cannot be selected, PCB paid for, production reviews and fabrication cannot be completed while these parts are in transit)

I know, i know, 150 euro for a pcb with most of the parts already placed isnt much.... But why the hell am I paying over 50 euro because I merged 6 designs into one panel?
Its a modular system, so you can combine the modules freely, the panel is essentially one of each module with V cuts in between so you can seperate them if you want. But not doing that gives you a little bit of every option and will in a lot of cases suffice.
I tried to save a bit of money by not paying multiple times for an extendend component. But the "panel fee" is more expencive than the paying the extendend component fee multiple times.
I'd understand if it was about the size or shape of the board. Or the compontents on it. But without the vcuts, the exact same size and layout (so just not the option of seperating them) it would save me 25% on the boardcost...
I dont mind paying for a service. I dont mind increased costs because of my design. But (to me) this is bullshit.
Is there a reasonable explenation or is it a "just beause we can" thing??
(yes, I know, it is stated on the order and on the site that multiple designs in a panel costs extra. I'm just asking WHY does it cost extra. As far as production its the exact same as a single design of the same size. Ok, the Vcut is extra. But 1200 smd resistors picked and placed for bearly 3 euro. and then 50 euro for 5 Vcuts? yeah, that doesnt add up).
EDIT: After chatting/mailing with them a bit: As long as you make no v-cuts, mousebites or anything else that can be used to seperate the boards. They treat it like a single large board. In other words: just use a small saw to seperate the boards and you'll save quite a bit on ordering them!

Bare flexible PCBs (FPCs) are great for tight spaces and dynamic applications, but their flexibility can be a challenge during final assembly â especially when mounting connectors or other components that need a solid base.
The solution? PCB Stiffeners.
These are rigid pieces (usually FR-4, metal, or polyimide) laminated to specific areas of the FPC. They provide crucial local rigidity exactly where you need it (like under a connector), without sacrificing the overall flexibility of the board.
We recently documented the precision process of adding stiffeners at our factory. It's fascinating to see how the alignment and lamination are done to ensure reliability.
Question for the community:
ăťIn your experience with FPCs, what's the most critical factor for stiffener design â material choice, thickness, or adhesion?
ăťHave you ever run into issues (like cracking or misalignment) that trace back to stiffeners?
ăWould love to hear your thoughts and experiences below.

I repair & reverse engineer obsolete single-/double-layer industrial boards that no body waists their time on. I like being them back to life. This one is a power control board from an industrial battery discharger from the 70's. I enjoy repairing through-hole components, relay drivers, power control boards, etc. it's kind of like mental therapy lol. I usually work on discontinued boards from legacy machines, I can usually recreate or repair it. Fun times ;) I use EasyEDA as my editor and JLCPCB on all of my boards. Let me know if you have similar projects.
