PRODUCT DETAILS

Before learning double sided PCB fabrication, we can take a view on its composition. Commonly speaking, for double sided PCBs, coppers are applied to both sides of the substrate. When we say a double sided or 2-layer board we are referring to the number of copper layers. The copper thickness can vary and is specified by weight, in ounces per square foot. Most PCBs have 1 ounce of copper per square foot but some PCBs that handle very high power may use 2 or 3 ounce copper. As for the carrier material, or substrate, is usually fiberglass. Generally, the most common designator for the fiberglass is “FR4”, which gives the PCB its rigidity and thickness.



Manufacturing process

How about the double sided PCB fabrication? Briefly speaking, the board is fabricated through the lamination with insulating material. Perhaps we can learn more by a diagram of manufacture process:
