The main aspect to consider here is the PCB complexity. A wide variety of pcb material racks options are available to you, such as use, type, and certification. When the line is in operation no open flame or light is allowed in the vicinity. AGS Limited (Adalin Global Sales Limited) offers Printed Circuit Boards and Electronics components sourcing solutions with a highly developed network of technical manufacturing resources. A basic PCB consists of a flat sheet of insulating material and a layer of copper foil, laminated to the substrate. PCB board material can use many kinds of materials, such as FR1, FR2, FR3, FR4, and so on, but the common PCB board material is FR4.
