So if you care about the second optical transicever bottleneck outside of EML/CW Lasers:
- $SANM (US)
- $TTMI (US)
- WUS Printed Circuit (TPE: 2316)
- Unimicron (TPE: 3037)
- Zhen Ding Tech (TPE: 4958)
- Gold Circuit Electronics (TPE: 2368)
Were winners for the optical transceiver PCB bottleneck.
There's some downstream players like FIC Global that benefits, not so much as a Fab but assembly.
Others like Unimicron are likely too large with other segments like ABF substrates to feel much of a difference.
US plays are more-so from reshoring to US supply chains, even though Chinese and Taiwanese players were main beneficaries.
$AVGO quote:
"Both Taiwanese and Chinese PCB suppliers are facing capacity limits, contributing to the delays, Ramachandran said, without naming the suppliers."
I have no open long positions in any of these right now.
I could be wrong, but I felt laser chokepoints ( $LITE, $SIVE, $MTSI, $COHR, Sumitomo) in optical supply chains to be much more compelling for structural re-rating.
