Multilayer FR4 PCB

Benefits

• Minimize the Size of the PCB: We can reduce the multilayer PCB board size with the help of inner layers as per PCB design rules.

• High Component Density: Multi layer PCB boards offer high component density.

• More Functions: As more wires and drills are placed on multilayer PCBs, more electronic component connections are made to achieve more functions. 
  
• Powerful Performance: We can place high-power components to achieve powerful performance.
  
• High Thermal Conductivity: Multi layer PCB boards provide high thermal conductivity.
  
• High mechanical Strength: It provides mechanical strength. So, we can easily handle heavy parts.
  
  
  

Disadvantage

• More Procedures: We need to get more procedures for handling them. Because the multilayer PCB manufacturing process is very lengthy.

• Higher Cost: Sometimes more costly due to the special processes required
  

• Long Manufacturing Time: It’s taking a long time to manufacture them.
