Hybrid bonding is an emerging packaging technology that combines the features of inter-chip bonding and intra-chip bonding. It utilises different bonding techniques to achieve interconnections between wafers and package substrates or within wafers to meet the needs of high-performance integrated circuits with complex interconnect structures. There are two common types of hybrid bonding: W2W can
FPC Bonding (Flexible Printed Circuit Board Bonding) is a technology that electrically and mechanically connects flexible circuit boards (FPC/FPCB) to other electronic components, rigid circuit boards (PCBs), or components such as displays through a specific process. This process is widely used in consumer electronics (e.g., mobile phones, tablets, wearable devices), automotive electronics, and medical devices
Differential signal line is mainly the difference between the traditional signal line corresponds to a ground line signal transmission mode, differential signal transmission is mainly two lines on the signal transmission, the two signals are equal in amplitude and opposite in phase. Relative to the traditional single-ended signal, it has a strong anti-jamming, can effectively
There is a significant difference between FPC PCB assembly and the assembly of rigid circuit boards, the main reason is that flex board is softer and less hard, if you do not use a special carrier board, it is difficult to achieve effective fixation and handling, so as to be unable to complete the printing,
