Micro-Mechanics (Holdings)

Given these few points, my thinking is MMH had not been breaking thru in sub-10nm space aka non of the sub-10nm chips are using MMH's products.

Similar thoughts.  I just started looking at the semicon space, and am trying to figure out what this company does.  

What I can gather is that it is involved in 2 ways of packaging chips: wire-bonding (very old) and die-attach (probably flip-chip - currently used for older chips).  Are they  involved in 2.5D or 3D packaging used for newer chips?  (A good description of 2.5D and 3D packaging is at https://www.fabricatedknowledge.com/p/se...ng-history).

So I get the impression they only handle low level chips (eg: household appliances) or mid-level chips (eg: automobiles), but not the high-end chips used for servers or iphones.  Is this true?  Their 2019 revenue breakdown: 63% of revenue was from countries that don't produce high end chips (China/M'sia/Sg/Philippines).

This might not be a bad thing, as there could be a long-term shortage of lower-end chips due to EVs and IOT (see 'Old chips cost More' https://www.fabricatedknowledge.com/p/th...iconductor).
