content: I was browsing the parts catalog on JLCPCB and LCSC last week and came across some new and amusing products (see the screenshots below). So, I couldn't resist and contacted JLCPCB support to request the footprints and schematic symbols of C48736161 (an umbrella), C48735895 (an air fryer) and C50325343 (a massager) for my new 12-layer PCB with SMT. Support answered "let me check" and disappeared for 20 min. I didn't have more time to wait and closed the chat, but will be curious to see those footprints.

content: I'd like to know what happens if you put C48736161 Umbrella on your BOM. I imagine a very confused email from the pick and place engineer.

content: I'm not sure why all these 0 availability stuff is added, for electronics at least. I wonder if a customer uses it then it automatically gets added to their database?Then there is the stuff you found, maybe its order on demand only? Probably only within china too, way too big to ship.https://www.lcsc.com/brand-detail/16087.html?s_z=n_umbrella

content: Hello, and thank you for pointing this out! What you saw were irregular or redundant data records generated during our data extraction from LCSC. Our system will regularly cleans these up to ensure accuracy and consistency.Thanks again for bringing it to our attention!

content: The big question is, are the massagers through hole or SMD?

content: Are the umbrellas available in the QFN or SOIC packages? If so, I may include them on my next project.

content: Quote from: Simmed on September 04, 2025, 01:03:47 pmI have sourced this kind of stuff from Alibaba etc. via Superbuy. Unfortunately, metal parts come with serious weight, and shipping is not that cheap any more.However it still way cheaper than sourcing locally; I just wish they would add cheap ground shipping with "I don't care how long it takes".However 2: Same shipping cost problems will apply to LCSC, too.Check this supplier for your studs (I have purchased from this supplier a couple of times, however have no connection to this supplier or Superbuy; there likely are other suppliers; however this one offers rather "exotic" stainless, Nylon, brass ones):https://www.superbuy.com/en/page/shop/shop/?shopid=68475736&platform=TB&sellerOpenId=I have also purchased IC heat sinks, if you want, I can post a link, too...
