Manufacturing Process of ISOLA 370HR PCB
The manufacturing process of ISOLA 370HR PCBs involves several precise steps to ensure high quality and performance:
Malighafi, including the epoxy resin system, kitambaa cha kioo, na foil ya shaba, 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.
Mifumo ya mzunguko imeundwa kwa kutumia michakato ya Photolithographic. Filamu ya picha (Mpiga picha) is applied to the laminate, wazi kwa ultraviolet (UV) mwanga kupitia mask, na kukuzwa kufunua mifumo inayotaka ya mzunguko. The laminate is then etched to remove unwanted copper.
Vias are drilled into the laminate to create vertical electrical connections between different layers. Shimo hizi huwekwa na shaba ili kuanzisha njia za kusisimua.
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, and a surface finish, kama vile HASL, KUBALI, au OSP, 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, Uadilifu wa ishara, na kuegemea.
