- LHD Technology produce multilayer PCB with advance capacity and high quality for more than 15 years. Multilayer PCB have some advantages than Single&Double side PCB,such as :
- 1.Higher assembly density.
- 2.Smaller size (considerable savings on space).
- 3.Increased flexibility,Easier incorporation controlled impedance features.
- 4.EMI shielding through careful placement of power and ground layers.
- 5.Reduces the need for interconnection wiring harnesses (reduces overall weight).
