Ultra-small Size Package Substrate Design Reference Guide
Designing ultra-small size package substrates requires meticulous attention to detail and a deep understanding of the materials and processes involved. The following sections provide an overview of the essential aspects of designing and applying these substrates.
Several key considerations must be addressed during the design phase:
Impedance Control: Precise impedance control is essential for maintaining signal integrity, especially at high frequencies. This involves careful design of the signal traces and the use of controlled impedance materials.
Gestione termica: Effective thermal management is crucial for high-performance applications. The design must incorporate thermal vias, dissipatori di calore, or other techniques to efficiently dissipate heat generated by high-power components.
Stabilità meccanica: The substrate must provide robust mechanical support to withstand thermal cycling and mechanical stresses during operation.
Affidabilità: Long-term reliability is ensured through the use of high-quality materials and precise manufacturing processes, preventing issues such as delamination and warping.
What Materials are Used in Ultra-small Size Package Substrates?
Materials used in ultra-small size package substrates are selected for their complementary properties to enhance the overall performance of the substrate:
Dielectric Material: High-performance dielectric materials, such as polyimide, LCP, or modified epoxy resins, provide electrical insulation and support high-frequency signal transmission.
Copper: Ultra-thin copper layers are used for the conductive traces, providing excellent electrical conductivity and allowing for fine-line patterning.
Prepreg and Core Materials: High-quality prepreg and core materials are used to form the multilayer structure of the substrate, offering electrical insulation and mechanical stability.
Solder Mask: A thin, high-precision solder mask protects the underlying circuitry and prevents solder bridging during assembly, withstanding the high temperatures of reflow soldering.
Advanced Adhesives: Specialized adhesives bond the layers together, providing mechanical stability and minimizing signal loss.
What Size are Ultra-small Size Package Substrates?
The size of ultra-small size package substrates varies depending on the application and specific design requirements:
Thickness: The overall thickness of ultra-small size package substrates can range from a few hundred micrometers to several millimeters, depending on the number of layers and the application requirements.
Dimensions: The length and width of the substrates are determined by the size of the components and the layout of the system. They can range from extremely small form factors for compact devices to larger substrates for more complex electronic systems.
The Manufacturing Process of Ultra-small Size Package Substrates
The manufacturing process of ultra-small size package substrates involves several precise and controlled steps to ensure high quality and performance:
High-quality base materials, such as copper-clad laminates and dielectric materials, are selected and prepared for processing. I materiali vengono puliti e trattati per rimuovere eventuali impurità e garantire una superficie liscia.
The dielectric material is applied to the substrate in multiple layers, con ciascuno strato che viene modellato e polimerizzato per formare i modelli di circuito desiderati. Questo processo viene ripetuto per creare il numero richiesto di strati, garantendo interconnessioni ad alta densità e prestazioni elettriche eccellenti.
Microvie e fori passanti vengono praticati nel substrato per creare connessioni elettriche tra gli strati. Questi passaggi vengono quindi placcati in rame per garantire una conduttività elettrica affidabile e un robusto supporto meccanico.
La superficie del substrato è rifinita con una maschera di saldatura ad alta precisione per proteggere i circuiti sottostanti e fornire una superficie liscia per il montaggio dei componenti. This step also includes the application of surface finishes, such as ENIG (Oro per immersione in nichel chimico) o OSP (Conservante organico di saldabilità), to enhance solderability and corrosion resistance.
Dopo la fabbricazione, i substrati sono assemblati con componenti elettronici. Vengono condotti test rigorosi per garantire che i substrati soddisfino tutte le specifiche di progettazione e i requisiti prestazionali. Ciò include test elettrici, Ciclismo termico, e prove di stress meccanico per verificare l'affidabilità e la durabilità dei substrati.
