Apple iPhone 18: TSMC’s WMCM Packaging Capacity Suggests Future iPhone Strategies

Recent analyses have revealed insights into Apple’s distinctive launch strategy for the anticipated iPhone 18 lineup, which is expected to feature a staggered release between fall 2026 and spring 2027. A critical factor behind this approach is the planned expansion of TSMC’s WMCM packaging capacity, which signals significant developments for Apple’s next-generation smartphones.

TSMC to Ramp Up WMCM Packaging Capacity to 120, 000 Wafers Monthly by 2027

A recent report indicates that TSMC’s WMCM packaging capacity is set to increase significantly from 60, 000 wafers per month in 2026 to an impressive 120, 000 wafers by 2027. This growth will be supported by enhancements to existing equipment at TSMC’s Longtan facility, known for its advanced InFO packaging technology, alongside the establishment of a new WMCM production line at AP7 in Chiayi. Additionally, TSMC is collaborating with partners ASE and Xintec to streamline wafer sorting and final testing processes.

For those unfamiliar, Apple aims to equip the iPhone 18 models with the cutting-edge A20 chip, built on TSMC’s 2nm process. This will mark a transition from traditional InFO packaging to WMCM, which allows multiple components—such as the CPU, GPU, and Neural Engine—to be integrated into a single package. This integration, facilitated by Redistribution Layers (RDLs), greatly enhances design flexibility while optimizing space for components, potentially allowing for larger batteries. The benefits of this packaging approach include:

Reducing the requirement for discrete components by embedding RAM directly into the module.
Eliminating the necessity for conventional interposers or substrates through the use of RDLs.
Incorporating Molding Underfill (MUF), which minimizes material usage and manufacturing processes.

In a related vein, Bloomberg’s Mark Gurman reported in November 2025 that Apple plans to introduce the iPhone 18 Pro, iPhone 18 Pro Max, and the much-anticipated iPhone Fold in the fall of 2026. Subsequently, the standard iPhone 18, the iPhone 18e, and potentially the iPhone Air 2 are expected to be released in spring 2027. It’s worth noting that some sources suggest the possibility of launching the iPhone Air 2 as early as spring 2026 or concurrently with the other variants in spring 2027.

With TSMC prepared to double its WMCM packaging capability by 2027, coinciding with the anticipated release of Apple’s more affordable iPhone 18 models—which are expected to drive considerable sales volume—Gurman’s insights into Apple’s staggered launch strategy are becoming increasingly substantiated.
