Design Considerations for Flip Chip (ABF) Substrats
Designing Flip Chip (ABF) Substrates involves several critical considerations:
Choosing the right materials with appropriate dielectric properties, conductivité thermique, and mechanical strength is crucial for optimal performance.
Efficient thermal management is essential to prevent overheating and ensure reliable operation. This includes the incorporation of thermal vias, dissipateurs de chaleur, and other cooling mechanisms.
Le maintien de l'intégrité du signal à hautes fréquences nécessite un contrôle minutieux de l'impédance de trace, minimiser la diaphonie, and implementing effective grounding and shielding techniques.
The substrate must have sufficient mechanical strength and stability to withstand manufacturing processes and operational conditions, including thermal cycling and mechanical stress.
The surface finish must be smooth and defect-free to ensure proper adhesion and alignment of components and to minimize signal loss and reflection.
Materials Used in Flip Chip (ABF) Substrats
Several materials are commonly used in the manufacturing of Flip Chip (ABF) Substrats:

Ceux-ci sont appliqués sur les plages de contact pour améliorer la soudabilité et protéger contre l'oxydation..
Dans certains cas, ceramics such as alumina (Al2O3) or aluminum nitride (AIN) may be used for their excellent thermal conductivity and mechanical properties.
Manufacturing Process of Flip Chip (ABF) Substrats
The manufacturing process of Flip Chip (ABF) Substrates involves several precise steps:
Les matières premières, dont ABF, feuille de cuivre, and epoxy resins, are prepared and processed into sheets or rolls.
Plusieurs couches du matériau de substrat sont stratifiées ensemble pour former une structure de construction. Ce processus consiste à appliquer de la chaleur et de la pression pour lier les couches.

Un film photosensible (photorésist) est appliqué sur le support, exposé aux ultraviolets (UV) lumière à travers un masque, et développé pour révéler les modèles de circuits souhaités. Le substrat est ensuite gravé pour éliminer les matériaux indésirables.
Des vias sont percés dans le substrat pour créer des connexions électriques verticales entre les différentes couches. Ces trous sont ensuite plaqués de cuivre pour établir des chemins conducteurs.
A smooth, defect-free surface finish is applied to the contact pads to ensure proper adhesion and alignment of components, as well as to minimize signal loss and reflection.
