① SA Source

Context Before

Source: Applied Materials

Process Flow: Packaging

Evidence

Hynix has been able to sidestep thermal compression bonding (TCB) because they have found other ways to manage warpage.

Context After

The use of force on the other hand increases the risk of causing damages to bumps. With stress applied to bumps, SK can also add more dummy bumps which also helps with thermal dissipation.

The process is also far more productive. A batch mass reflow and single over-mold step are used for joint formation, compared to a complete TCB step for joint formation for each and every layer with TC-NCF.

② Atomic Claim

Hynix 因能以其他方式管理 warpage,因此可以避開 TCB。
