Thanks @Andrew Wingate , this is a great start though it would be ideal to have it for our bondhouse.
Can you share what they are called ?

They don't have a guide like this

Sad, nothing you can do about that. 
Can you share the wirehouse is called ?


[2026-08-10 10:39 p.m.] anfroholic
I can't read chinese

I think knowing what machine it is would be more useful?


[2026-08-10 10:52 p.m.] namibj
Assuming it's a standard machine that has specifications on e.g. it's toolhead's clearance and the general principles of it's guidance/alignment system, etc.?

That and the wire dimension and material would be a golden trio.

I don't have a model number

Man the packaging house pictures always look so cool. 😍


[2026-08-10 11:02 p.m.] essen__
Can you confirm it is gold wire?


[2026-08-10 11:02 p.m.] anfroholic
Aluminum iirc

Hum, looks like I missed something then 🤔


[2026-08-10 11:23 p.m.] namibj
yeah it's like 0.8 mil or such, a lil thinner than what's more-standard, but something about these chips dictated the pick. mithro had posted a pic of it a few months ago.

The only gold in the Run1 COBs as they get shipped is at the mezzazine and the ENIG of the PCB.

awww that optical system looks like it could track not just the die but also the board.... 🙁


[2026-08-11 2:05 a.m.] essen__
Looks like I need to go look for that pic.


[2026-08-11 2:06 a.m.] essen__
Hum, interesting.
I wonder if the TT chip also used Al. 🤔


[2026-08-11 2:07 a.m.] namibj
I thought that was part of W.S. Run1?


[2026-08-11 2:11 a.m.] essen__
It was. You do fingers differently between Au and Al, and the bonding looks like it followed the Au rules. Though the Au rules might be more constraining so they could also have gone with the worst case.

I'm pondering purchasing one of these machines that we can then replace the automation system with something that captures images of the bonds as they are created.
