Materials Used in ISOLA 370HR PCB
ISOLA 370HR PCBs are made from a specific blend of materials designed to provide superior thermal, электрический, и механические свойства:
The 370HR uses a high-performance epoxy resin system that provides excellent thermal stability, механическая сила, и химическая стойкость.
The laminate uses a woven glass fabric reinforcement that contributes to the material’s dimensional stability and mechanical strength.
High-quality copper foil is used for the conductive layers, обеспечение превосходной электропроводности и надежности.
The prepreg material, which is the uncured version of the laminate, is used to bond the layers of the PCB together during the lamination process.
Manufacturing Process of ISOLA 370HR PCB
The manufacturing process of ISOLA 370HR PCBs involves several precise steps to ensure high quality and performance:
Сырье, including the epoxy resin system, стеклянная ткань, и медная фольга, are prepared and processed into sheets or rolls.
The laminate is created by bonding layers of copper foil and glass fabric impregnated with the epoxy resin system. This process involves applying heat and pressure to cure the resin and form a solid, stable laminate.
Узоры схем создаются с помощью фотолитографических процессов.. Светочувствительная пленка (фоторезист) is applied to the laminate, подвергается воздействию ультрафиолета (УФ) свет через маску, и разработан для выявления желаемых схем схем. The laminate is then etched to remove unwanted copper.
Vias are drilled into the laminate to create vertical electrical connections between different layers. Эти отверстия затем покрываются медью, чтобы создать проводящие пути..
Multiple layers of the laminate are stacked and bonded together using prepreg material. The stack is then laminated under heat and pressure to form a multi-layer PCB.
A solder mask is applied to protect the copper traces and vias, и отделка поверхности, например HASL, Соглашаться, или ОСП, is applied to the exposed copper pads to enhance solderability and protect against oxidation.
The finished PCBs undergo rigorous testing and inspection to ensure they meet the required specifications for electrical performance, целостность сигнала, и надежность.
