It is identical, thus assess industry when both it is relevant can not but say it is identical.Again for example：Because there is integrated circuit part to be loaded in circuit board
On, thus news media he be referred to as IC plates, but substantially he be also not equal to printed circuit board (PCB).The printed circuit that we generally say
Plate refers to the circuit board of bare board-i.e. no upper component.
The type of cooling of current PCB is mostly that surface is air-cooled, and overall cooling effectiveness is very slow, it is difficult to meets need
Ask.
