SpaceX’s in-house packaging plant hit a production yield bottleneck! Executives reportedly plan an April visit to Taiwan to strengthen the supply chain, and three Taiwan-based companies are expected to benefit

Musk pushes for vertical integration in semiconductor manufacturing, but Texas’s in-house FOPLP packaging plant and PCB plant are both facing yield bottlenecks, causing both mass-production schedules to be delayed. Taiwan’s supply chain not only is difficult to replace in the short term, but also stands a strong chance of receiving an additional 2+ years of extra orders because SpaceX continues to place releases. Market rumors say that SpaceX’s senior leadership plans to visit Taiwan at the end of April to hold in-depth meetings with packaging and PCB supply-chain companies.

SpaceX’s Texas in-house plants are stuck; FOPLP mass production pushed to mid-2027

DigiTimes reports that in the first phase of a new plant for fan-out panel-level packaging (FOPLP) in Texas, where SpaceX’s operations are located, although equipment handover work has largely been completed, the yield performance is far worse than expected. The core engineering team consists of only about 10 people, and severe talent shortages have led to lower efficiency. As a result, the formal mass-production schedule has been pushed back significantly—from the originally planned Q3 2026 to mid-2027.

The plant’s Phase 1 plan targets monthly production capacity of 2,000 units, with packaging dimensions of 700mm×700mm, which is the largest specification among currently mass-produced products in the industry. Each unit can package up to 100k chips. The plan also calls for building another 2 to 3 plants and continuously expanding cooperation with Taiwan-based equipment and materials suppliers.

As for the PCB plants, the problems are also substantial. SpaceX’s Texas PCB production line currently has a yield of only about 60%. Compared with the common benchmark of over 90% among Taiwan peers, the gap is stark, and the short-term inability to resolve capacity shortfalls remains difficult.

Technology transfer relies on Singapore’s PEP; a dual-track supply model diversifies risk

To quickly enter the packaging sector, SpaceX mainly conducts technology licensing and transfer through Singapore’s PEP Innovation. PEP, many years ago, also collaborated with China Resources Micro to establish Chongqing Silicon Board Microelectronics, giving it extensive experience in technology transfer for advanced packaging. At present, its cooperation partners include STMicroelectronics (STMicroelectronics), Innolux, and China’s panel-level packaging ecosystem. This model is similar to the authorization-service framework that Powerchip assisted India’s Tata Group in building a wafer fab.

On the supply strategy, SpaceX adopts a dual-track parallel model to spread risk: the external supply chain is handled by STMicroelectronics for wafer supply and packaging, while GlobalFoundries (GlobalFoundries) is responsible for contract manufacturing, together with Innolux taking on the packaging business; internally, it continues to advance its Texas in-house plant plan, aiming to gradually reduce reliance on external suppliers.

Senior SpaceX leadership will visit Taiwan at the end of the month; Taiwan suppliers continue to benefit

Because the yields and capacity of SpaceX’s in-house Texas plants are not as expected, SpaceX continues to release orders to external parties, making Taiwan supply-chain companies the most direct beneficiaries. Reporting estimates that order momentum from companies such as Innolux (3481), Walsin (2313), and LEOCH (2367) can continue for another 2+ years.

Starlink’s low-Earth-orbit satellite service is the core engine driving ongoing demand expansion. Semiconductor companies estimate that globally, Starlink adds more than 20k users per month. Applications range from personal communications to vehicle connectivity, aviation, military use, and infrastructure development in remote areas. In addition, with conflicts continuing across countries in recent years, military communications demand continues to rise.

A source said that SpaceX-related senior executives are expected to visit Taiwan at the end of April. They are expected to hold talks with Taiwan supply-chain makers such as PCB and packaging firms to further solidify cooperation.

Terafab’s ambition remains undiminished, but in the short term it’s still hard to break away from Asia’s supply chain

Looking long term, Musk’s semiconductor end-to-end blueprint has not wavered due to real-world challenges. Its Terafab plan is backed by funding from Tesla, SpaceX, and xAI. It combines the three companies’ huge in-house chip demand to fill capacity, and also brings in Intel as a fab-building partner to provide process technology transfers and service support.

However, semiconductor industry players say that Texas’s talent gap and the supply-chain cluster have not yet taken shape, which will become Musk’s biggest obstacle to achieving full vertical integration. Within the next few years, it will still be difficult to shake reliance on Asia’s supply chain. Even so, with abundant capital and support from major firms such as Samsung Electronics, the possibility that Musk could build a “new force in wafer manufacturing” outside of TSMC is gradually moving from imagination to reality.
