Copper-board
Como fabricante de PCB. Alcanta PCB company offer tablero de cobre. Sobre el espesor del cobre. hay algunos tipos diferentes. el primero: PCB de cobre pesado. en la superficie de los materiales base FR4. el cobre se hará con 2 onz(70uno) a 6 onz(210uno). Algunos tableros multicapa. the inlayer will make the heavy copper too.
the second types. like a two layer copper pcb. it will be made with the fine copper base. we call it PCB metálico too. you can see the below pictures.we can produce the two layer copper base pcb thick from 0.2mm to 1.6mm. the core will be copper. not FR4 base.
the third type. Alguno multilayer boards. p.ej. 8 Layer FR4 PCB. from L3 to L6 layer. it needs to make 1.2mm thick copper. top and bot side use FR4 base. PCB total fnished thick is 1.57mm. or some PCB rígido-flexible will make the Copper core.
Si tienes alguna pregunta. please check with our engineer. we produce PCB from 2 capa a 90 capas. alta calidad, More cheaper price.and fast lead time.our company has made the PCB with IPC Class II and IPC Class III. muchas gracias!
