Hello I own a small PnP business.
We very reliably Pick-and-Place 300µm pitch BGA family part.
Without much knowledge of the silicon making process.
Would it be possible to create a 300µm grid of 100µm gold pads on the top metal layer;
reflow some ready made balls on the top of the chip;
And reflow it directly to the PCB ?
(I guess add some epoxy at some point too)

I don't particularly care for WLCSP or BGA, QFN is much easier to inspect, but WLCSP looks like a packaging method which doesn't require much equipement beyond a good 0402 or 0201 class pick and place machine.

(Such pick and place cost start at 1k$ to 2k$ but they come with a steep learning curve to get such good results.)

The chip itself has aluminium top metal and silicon nitride passivation.
It is possible to expose only the bond pads from the passivation (there are options already prepared in the design rule checks).
If you have an ability to bond that out through a flip-chip process, at a cost cheaper than the chips themselves, at these quantities you can see on the website (i.e., 1k chips for 4~10 $ each depending on if half or full slot and depending on whether early bird discount applies), please share.

Notably, per my research, there are electroless zincate base plating methods available to build up a standard ENIG stackup or other such solderable surface on the aluminium, without needing high vacuum or any further lithography.

I'll draw a few test pad-pairs of realistic proportions (but not the same proportions throughout) that target bonding via AnisotropicConductiveFilm to high-fidelity (mostly due to copper thickness though) COTS FPC (polyimide core, 0.33 oz copper either side, "solder mask" much less detailed than the copper features themselves, so fine pitch would have to be without solder mask bridges between pads), specifically the 2L FPC special offer at JLCPCB (for prototyping convenience, and as it's realistic).
If you happen to have some plating/bumping targeted pad-pair geometries in mind, feel free to join/contribute/share.

we haven't yet found an affordable performant (more than the ACF can offer, at least) option for flip-chip packaging at the quantities we're dealing with here, sadly, so therefore contributions would be well-received.

Ok so I see 3 problems
1. readying the ICs for accepting the balls
2. applying balls, I don't have experience given commerce ICs come with balls
I've seen plenty of electronics repair people doing this everyday with nearly 100% yield and artiasanal equipement (jigs and laser cut steel stencils), so we should be able to find that knowledge in the wild
3. soldering to a PCB, that I know how to do, there are lots of tricks, but basically you must have a flat PCB (ENIG), a good PCB footprint, and a well callibrated pnp, then you "just" place it correctly ~+-80µm in XY and it always work (/ I never had a failure yet)

(AFAIK, as long as this does not inhibit the wire bonding ability for those customers/slots who have planned to do that, it would be possible to do the electroless/plating build-up pre-dicing at wafer-scale, provided it's not a significant expense to treat the other dies; but aside from any thick gold options, I don't think any of the plating here would have reason to be too expensive to afford wasting it on the non-flip-chip dies just to get to plate the flip-chip-dies before the wafers get diced.)

If you have connections/access to plating that can turn that into something you can "just" solder, I believe appropriate stencil thickness should suffice to form a robust-to-manufacture gap between the die and the PCB?
Because that's the main reason for the balls, right, vs. "just" using LGA?

I have zero LGA experience.
If you get balls on an IC it's really easy to reflow*
*assuming you've got high quality balls and they havn't been reflowed more than 2 times already and are full of oxides.

ACF is the flip-chip/non-soldering bonding technology that's mainstream used to attach active-matrix displays and other such circuits on glass to more traditional printed circuits and also to directly attach driver ASIC dies to the display glass.
It's low cost and doesn't necessarily need plating, but it's high resistance compared to soldering and only liked by the display industry because it's much easier to hot-press an epoxy carrier tape (the ACF matrix loaded with nickel balls that when compressed perform the anisotropic conductive aspect) for 10 seconds at 200C than to deal with flux and solder-melting temperatures when a TFT display's traces-on-glass are involved.
I'm placing a few test pad pairs (likely one connected to GND and the other to VDD, or something; to ideally test that the adjacent pads don't short out to each other) on otherwise "spare" silicon area on the current tapeout (Run2), to hopefully qualify this flip-chip process for (limited) production use on the next run.

If my researches are to be believied, adding gold to the top of a wafer is a standard process. Is that something the fab would be able to offer ? (altho I guess it would do the whole wafer)

I'm not aware of global foundries offering us plating options, sadly; at least not at these quantities we buy from them (for them it's literally "singular full MOQ" size; they do offer half-batches for very small quantities but the cost per chip is like +50% or even +80%, so it's not suitable for production orders).
There should be some third party facilities offering such services, though.

I am not planning to have it work open-loop at substantial precision; also it's not that much reach compared to PCBs.
This example here is appriximately 230 nm step size in a 23mm cube; so "just" 100k steps; and that's not accuracy but step size.

find out what geometry you'd think you'd need, and what you'd think would certainly be practical enough to pull off, and if it's reasonable numbers I'll draw you a couple pads and you'd (if I don't mess up) be able to expect a couple dies to try with.

Sputtering UBM looks easier but require a lithographic step.
I know they sell 2µm maskless lithography machines.
We need something like 20x less precise than this for my 300µm BGA I'm looking for.

the current wire bonding is basically 0.1mm pitch QFN if we'd flip-chip that.

One of the users, TinyTapeout, has among other parts rows of analog tiles avilable for small users to put test designs on, and those are basically 300um squares; I'd ideally hope we could manage to fit two bumps on each of them at least in a line and contact them out; if the chip has multiple lines it'd be acceptable to use different PCBs that each only contact the bumps of a single row (and the outer normal/generic/multiplexed IO that currently uses the normal wirebonding pad frame).
That would allow economic testing of things like differential receivers/transmitters which would have issues with the analog MUX parasitics today.

We'll not do useful circuits connected to the flip chip pads this run, there's no time for that; we'll just do enough to let us test if the pad is shorted out and ideally to let us _somewhat_ quantify the contact resistance of the bond.

Ok so the LLM is giving me lots of info and it's hard to verify any of it.
What I know:
About pitches (center to center) worth testing 300µm and 200µm (if room for one go 300µm, less variables).
You can add 100µm if you want but I don't believe in it, PCB fab shops don't usually go that small so it can't be easy.
If you've got lots of space add 250µm and 150µm.
Assuming my PCB rules translate to ICs, never use a square will fuck up the ball.
A square with extremely big corner radius value works, but the best is a plain circle.

btw, if one can grow pillars from the exposed top metal (aluminium), and those are of a sufficiently "solderable" surface, then dipping the pillars onto a sheet of silver/copper low-temperature sintering paste followed by carefully placing it onto a PCB with matching pad geometry, and then applying the sintering heat/pressure (something like 200C for 30 minutes seemd to be realistic to expect, iirc), is also something to keep in mind/consider-as-option; in theory that can also be printed as it's basically like _very_ fine solder paste with consistancy depending on what particular variety (iirc the relevant ones for ourt die sizes are all conveniently available in the more-liquid-y forms, though; it's just larger dies that need the drier stuff to not have issues with letting the fumes escape during the pressing).

100um is not sustainable on laminated PCB (it is I think on build-up organic substrates like you know from modern desktop/server CPUs) for more than like 2 rows due to issues with PCB via manufacturing and layer thickness minimums; it's otherwise not _that_ much of a problem tho.

it also says you want maximum vias on the aluminium to prevent delaminiation when reflow

~~For the opening diameter I've taken a simple 50% of the pitch~~ nvm I've changed my mind, at worst balls touch and no problem
some manufacturers prefer a bit bigger because it's easier
the bottleneck is the bulge of balls, you don't want them touching

**Content**
```text
Assuming (afaik reasonable to do given the pricing fits what I recall as typical for these low end processes) the 2000$/wafer for buying extra undieced wafer(s) is around the marginal per-wafer cost, that'd be a reference price level to compare the plating to, if it's done wafer-at-once in a way that doesn't break the ability to wire-bond dies that expect to get wire-bonded.

(one of the enig siblings is suited to wire bonding on top of the solderable plating; ofc it can't make a thick bump but doing it wafer-at-once means that one doesn't need to hold onto hundreds of tiny dies during the plating process steps)

I'm talking about the silvery vey very mirror shiny squares around the very outside edge of the die (technically there's like about half or third of square size gap to the edge, and there's for these dies from Run1 at least an omnipresent narrow (about iirc 1/5th the width of the squares) shiny ring around the entire die on the outside)

the edge is the sealring which for dies marked as "wire bonding" has a mandatory exposed strip of metal, which in thse dies is very very close to the squares, which the wire bonding machine doesn't care about but any simple ACF bonding would very much care about.

it's not worth the litho at the very very edges because there's too much edge close by anyways so the chips aren't too usable anyways; maybe they expose some filler pattern to help the chemical-mechanical-polishing stay more well behaved though, not sure

@namibj after some more searching I don't know how NXP is using 50µm opening or if I'm reading that diagram correctly.
For 300µm pitch an octogon between 180µm and 100µm diameter should be workable
