mind with the number of pins you're looking for and how to best accomplish that. \nOn one hand we just have the sheer number of pins and I am not sure how many wire bonds @Tim 'mithro' Ansell is wanting to let people have. \n\nThat said, the picture here has 78pins and there is some room for some other things as well--and/or instead. \nInstead could also just be testpoints. They don't need to be brought down to the main PCB board and can remain on the COB \n\nAnother idea, is to have some solderable jumpers or 0R resistors that can bridge a pin from the COB to the pcb. \n\nAnd finally if something like the solderable jumper is a viable option, is there some way to have the same effect on the die itself with a MUX or the like. I am trying to wrap my head around the actual utility here. There are *user_pins* and *power_pins* I can understand the desire for more pins, but don't know what that means in practice and if it could/should be more *shared_pins* \n\nThanks", "author": { "id": "756011607603019777", "name": "anfroholic", "discriminator": "0000", "nickname": "Andrew Wingate", "color": null, "isBot": false, "roles": [ { "id": "1423020172595298314", "name": "Mod", "color": null, "position": 4 } ], "avatarUrl": "2025-10_media/67bd670a335a2f955fb2ded57088a2cb-675B3.png" }, "attachments": [ { "id": "1425123433942876273", "url": "2025-10_media/image-AC763.png", "fileName": "image.png", "fileSizeBytes": 57428 }, { "id": "1425123434333081700", "url": "2025-10_media/image-499F0.png", "fileName": "image.png", "fileSizeBytes": 80470 } ], "embeds": [], "stickers": [], "reactions": [], "mentions": [ { "id": "169786952432746498", "name": "mithro_", "discriminator": "0000", "nickname": "Tim 'mithro' Ansell", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-10_media/9679bb77da48d47c905b398d98a83780-75B68.png" }, { "id": "596068704471482370", "name": "246tnt", "discriminator": "0000", "nickname": "tnt", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-10_media/88d17af9d19ab43565b0c46751ef7d12-DFEE5.png" } ], "inlineEmojis": [] }, { "id": "1425166259611504783", "type": "Default", "timestamp": "2025-10-07T17:01:54.6+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "I asked in the discord of another product (tinyclunx) that uses two of these connectors about alignment issues, this was the reply FWIW:\n\"As in the 2 DF40 Hirose connectors being misaligned/slightly rotated?\nSo far, have not seen anything liek this.

Is that still true for the COB option ($8500), or is there a default padframe we would need to follow? \n2) If we can use our own padframe, I’m assuming we would also need to design the wire bond as well?\n3) For the default padframe that @tnt mentioned above with the 56 “user io” bond pads, can that be generated with the following template? https://github.com/wafer-space/gf180mcu-project-template\n4) Would the template also generate a seal ring? We had an issue with the 2025 Chipathon where a seal ring was not generated with the padframe. I believe GF will end up adding the seal ring for us.\nApologies for the many questions.

Looked around a bit but I am left with the following question. \n\nI was talking to @asc and he mentioned that you are developing a template with 74 pads; ( 20 + 17 ) x 2\n\nThe reticle is sqrt(20) so about 4.5mm on the side (although maybe the reticle is rectangular). In any case 20 pads on 4 mm would mean 200um center-to-center pitch. That sounds large. Obviously we do not need to push is to 50um which likely might not work for COB, but what is the guideline for the COB?\n\nWhat is the center-to-center pitch on the PCB pads?\n\n74 pads would work for out MOSbius chip (https://mosbius.org) , but more pins can always be put to very good use for our application ... \n\nFinally, we would like a version which is dual in line style so we can put it in a breadboard. You can see our current PCB (with a chip in a package) attached. \n\n@Tim 'mithro' Ansell So how would we go about this? Do all the designs in the run use the same # pins and positions for the COB at 8,500. Or if we do the designwork of the PCB, can we make our own, or does that come at a higher cost?\n\nMany thanks!

For example, all of the 54 pads could be used for analog. The remaining 20 pads are used for power and ground and should not be changed, since they will be connected to the power/ground rings of the CoB footprint on the PCB.\n\nIf you do your own packaging, you could fit more pads into the padframe, or remove the padframe completely - this is up to you.\n\nI believe there are different daughter boards in development in the #\uD83D\uDCE6-cob channel.\n\n- Leo\n\n@Tim 'mithro' Ansell would it be possible for someone to design their own padframe and choose the CoB option?

Availability seems very low for this size\n\n**Castellated:** This is another viable option, but this means that users must either supply the COB to a PCBA at the time of assembly, or try to solder this chip on their motherboard themselves. This is doable but ~70 pin castellated solders gets old fast. \n\n**2row 1.27 headers:** This is my latest iteration. This option has all the pins broken out (76) so users can do whatever they like. The picture on the right can probably be wave soldered, reducing the cost as much as possible because things add up fast when there's a lot of pins. \n\nPersonally, I would like to see the 50pin mezzanine connector version stay on the smallest footprint version for anyone wanting to use these in application (not sure if there are any) but that option allows a PCBA to assemble an entire board and user does not need to supply anything, then can just plug in themselves easily. This decision is based on price and availability as well. \n\n@asc, I don't know what where you'd land on desires here, but an option as well for you would be the 50pin mezzanine and a bunch of testpad/breakout type areas where you could attach a probe for any pin that is not part of the 50 on the connector. \n\n*We don't know the variability granted by the wirebonders. Ideally the PCB portion could be anything and as long as the pads are all in the same positions, granting @asc and others more pins taken from the power rails needed for @tnt*\n\nOpinions/ suggestions anyone?\n@Tim 'mithro' Ansell", "author": { "id": "756011607603019777", "name": "anfroholic", "discriminator": "0000", "nickname": "Andrew Wingate", "color": null, "isBot": false, "roles": [ { "id": "1423020172595298314", "name": "Mod", "color": null, "position": 4 } ], "avatarUrl": "2025-10_media/67bd670a335a2f955fb2ded57088a2cb-675B3.png" }, "attachments": [ { "id": "1426219400008040593", "url": "2025-10_media/image-D4250.png", "fileName": "image.png", "fileSizeBytes": 153920 } ], "embeds": [], "stickers": [], "reactions": [], "mentions": [ { "id": "378788837452677120", "name": "asc9742", "discriminator": "0000", "nickname": "asc", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-10_media/3-FB033.png" }, { "id": "169786952432746498", "name": "mithro_", "discriminator": "0000", "nickname": "Tim 'mithro' Ansell", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-10_media/9679bb77da48d47c905b398d98a83780-75B68.png" }, { "id": "596068704471482370", "name": "246tnt", "discriminator": "0000", "nickname": "tnt", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-10_media/88d17af9d19ab43565b0c46751ef7d12-DFEE5.png" } ], "inlineEmojis": [] }, { "id": "1426224298988671170", "type": "Default", "timestamp": "2025-10-10T15:06:10.845+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "I'd definitely avoid 1.27 headers, they're a pain.", "author": { "id": "596068704471482370", "name": "246tnt", "discriminator": "0000", "nickname": "tnt", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-10_media/88d17af9d19ab43565b0c46751ef7d12-DFEE5.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [], "inlineEmojis": [] }, { "id": "1426224923856211978", "type": "Default", "timestamp": "2025-10-10T15:08:39.825+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "I prefer mezzanine, HCTL seems to have quite a few 70~100 pin options if using 2 conectors is not acceptable.\nAlso instead of castellated, you can do just plain LGA with just 0.5 mm pitch pads on the bottom to be reflowed on a host PCB.", "author": { "id": "596068704471482370", "name": "246tnt", "discriminator": "0000", "nickname": "tnt", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-10_media/88d17af9d19ab43565b0c46751ef7d12-DFEE5.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [ { "emoji": { "id": "", "name": "\uD83D\uDC9C", "code": "purple_heart", "isAnimated": false, "imageUrl": "2025-10_media/1f49c-71A75.svg" }, "count": 1, "users": [ { "id": "756011607603019777", "name": "anfroholic", "discriminator": "0000", "nickname": "Andrew Wingate", "color": null, "isBot": false, "avatarUrl": "2025-10_media/67bd670a335a2f955fb2ded57088a2cb-675B3.png" } ] } ], "mentions": [], "inlineEmojis": [] }, { "id": "1426227628049829908", "type": "Reply", "timestamp": "2025-10-10T15:19:24.555+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "Thanks.

But I do not think we are unique in the \"need for pins\". I did a quick area estimate planning exercise yesterday -- see below -- and we have tons and tons of spare area and could put in a lot of functions, but just need more pins ... That is in part due the nature of our MOSbius design, but is true for many designs by starting designers where you want a good number of pins for debug.

It took us over a year to establish a flow that didn't break most of our assemblies :( This was a combination of company negotiation time and lots of surprise temperature incompatibilities. \n* You will likely find wirebond/COB houses and SMT assembly houses who will each want to do their process first on a bare PCB. I have set up prototyping runs in both situations, and only once found a company that could do both (at higher cost than the two phases individually, unfortunately). I have not gone back to that company because initial project setup took months and over 150 emails. Then that sales engineer retired and I loathed the idea of explaining our assembly to another person. I think they contracted out the COB portion but at least they were responsible for ensuring order of operations.\n* Advantages to SMT going first: get the high temperature steps out of the way. We were using transparent epoxy that swelled in high temperature, ripping off bondwires. As others have already mentioned, opaque epoxies can generally withstand high solder temperatures.\n* Advantages to COB going first: wirebond heads work easiest when the bonding surface is flat and there's nothing for the bond head to crash in to. Also they are often attached via vacuum chuck which cannot seal if there are parts on the backside of the board. Custom chucks can be fabricated to enable vacuum seal, at increased NRE cost.\n* We had some designs packaged QFN but the hassle and cost wasn't ultimately worth it.

And given the most I’ve seen for passing bond layouts has been glorified napkin sketches. We don’t want to be doing this all the time. \nThe overall layout here has 74 bondpads and 70 pins that can be brought through the mezzanine connector. \nAgain, it’s my suspicion, but keeping things the same will pay in dividends. \nI think the process looks something like this. \n\n### COB PCB \nPCB houses already deal with variety, I don’t see why this would be different. The current layout is a 7x6 grid (42) dies per panel. 25 panels is 1050 COB. We will likely share a few basic designs and all most would do is change the silkscreen to their liking. \nFrom @Tim 'mithro' Ansell side, he is looking at purchasing 10s of thousands of these connectors making for happy conversations with suppliers. With Crowd Supply’s connections with Mouser, there may be a way to get them to stock the mating components. \n\n### Glue and Die Placement\nAll the die are the same size. If there is a mechanical solution for adding the glue (I believe there is) having the same layout for everything will make them very happy. Cost is inversely proportional to happy.

I think that's been pretty solidified. \n\nI am looking for anything else, and what we think people would want. @Tholin you seem to be the only other one who has expressed interest in another--that being a dip version. Is this what you want? Would you be opposed to having a dip version that looks like these versions above, where the actual dip layout is in fact a carrier? https://discord.com/channels/1361349522684510449/1408134567491145728/1431637886314352834\n\nIf we're looking for some other version that would be lower cost, what would you all think of a 50pin mezzanine, this could have 55pads or so? The cost difference from 40pin to 50pin is basically 0, so real difference is offers from wirebonder. \n\nSharing the source and production files will already be done. But also have a relationship to Mouser through CS so if we wanted them to stock panels of DIP carrier boards that fit our *to be determined standard* I'm sure this is something that can happen if we think there will be some kind of demand. \n\n@Leo Moser (mole99) I'm pretty sure there are some other files somewhere that map the [config](https://github.com/wafer-space/gf180mcu-project-template/blob/main/librelane/config.yaml) to the actual pad locations.
