Where does all the weird Chinese component terminology come from?

From Wikipedia:

in his [Lee De Forest's] earliest versions [of the Audion], this was simply a piece of wire bent into the shape of a gridiron (hence grid).

This is a grid

Consider that the name came from the very first tubes.  I bet the grid was, in fact, a "grid" in those early tubes.

- Both SMD and through-hole parts have it in their description.
- Both PnP-able and non-PnPable parts have it.
- Even tactile switches are labelled with brick nogging

Maybe any part that has one line of pins (eg flat flex connector) or multiple parallel lines of pins (eg 2-row headers, tactile buttons) is "brick nogging"?  Exclusions include parts with lines of pins in non-parallel directions (such as LQFP).  A bit odd.

It just means "surface mount". In some cases LCSC didn't fix the translation/category (under Mounting Type).

Yes, some of them do have through hole support leads (USB connectors). Digikey would call those "surface mount, through hole" to cover all the bases. LCSC doesn't go to that level of detail.

But a vacuum tube grid looks like this

Fun fact: its Chinese translation is, indeed, a "Fence electrode" (柵极). The same terminology is also reused for the gate of FETs. So... you know what's going on if you ever see a AliExpress vendor is selling "MOSFET grid driver" in the future... (though, this mistranslation per se is not common, as "gate driver" is a dictionary word).  :-DD

--- End quote ---

Notice the little brick-shaped sections that can be cut away?

"Brick nogging" is a mistranslation of "vertical" + "SMD". I already explained the detailed etymology behind this mistranslation (https://www.eevblog.com/forum/chat/where-does-all-the-weird-chinese-component-terminology-come-from/msg4313581/#msg4313581).


--- Quote ---My other favourite translation on LCSC is "Lying", eg "50mA 12V SPST Lying Round Button Plugin Tactile Switches ROHS".  No it's not a phonetic English spelling of a Chinese name being used as a brand name.  No it doesn't mean the part specs are false.  It means it's a right angle part, like a right-angle PCB-mount slide switch.

It's exactly the other way around. The translation is actually "horizontal". "Horizontal" (Lying) refers to the fact that the touchable part of the pushbutton is 0-degree, in parallel with the board. Meanwhile, "Vertical" (Brick nogging) refers to the fact that the touchable part is 90-degree with respect to the board.

The same terminology is also used for all kinds of connectors, such as a USB connector. A "lying" one would be something you usually see on a PC motherboard, for example.

As a demonstration, compare these two connectors.

"Brick nogging 6.2mm SPST 12V SMD"
https://www.lcsc.com/product-detail/Tactile-Switches_Diptronics-DTSL-61N-V-T-R_C495902.html

and

"Lying SPST 12V Plugin"
https://www.lcsc.com/product-detail/Others_C-K-PTS645VK832LFS_C285521.html

(BTW, "plugin" is yet another mistranslation. It should've been "through-hole".)

My apologies.  Thankyou niconiconi.
