Re: 'None of the actors can be taken at face value
The embeding of active/passive components can be traced to the 1980's... and IBM published a paper
( https://www.jstage.jst.go.jp/article/jiepeng/2/1/2_1_134/_pdf/-char/en )
Embedding components inside a PCB motherboard or a substrate provides literally a new dimension to achieve the needs of today’s high end electronics manufacturing. Component embedding inside a substrate is not a completely new idea, and several technology approaches have been in development over the years – the first real attempt to commercialize an embedding technology was done by GE in mid 80’s. But only now has the market evolved to accept component-embedding solutions and at the same time the infrastructure has matured to a level where component embedding becomes a commercially viable solution.
so there are no technical obstacles...
