0. 4mm PCB thickness is the beginning of multi-layer PCB, which is almost the minimum thickness for PCB engineers to design multi-layer boards. 0. 4mm PCB thickness is the beginning of multi-layer PCB proofing

by combining different core thicknesses and prepreg sheets, a wide range of finished PCB thicknesses can be realized. However, the selection range of various laminate thicknesses provided to customers is 0. 008 inch to 0. 240 inch, including 0. 2mm (0. 0079 inch), 0. 4mm (0. 016 inch), 0. 5mm (0. 020 inch), 0. 6mm (0. 024 inch), 0. 8mm (0. 032 inch), 1. 0mm (0. 04 inch), 1. 2mm (0. 047 inch), 1. 5mm (0. 062 inch), 1. 6mm (0. 063 inch), 2. 0mm (0. 079 inch), 2. 3mm (0. 091 inch), Etc. The circuit board thickness is the measured mm thickness of the substrate, including the copper foil at the top and bottom. Therefore, the thickness of the circuit board does not represent the final thickness of the PCB, because we need to add electroplating, solder mask, etc. if you need 0. 4mm final thickness, then we will use 0. 3mm raw materials to make your PCB. /P> Rayming PCB thickness range: 0. 2mm pcb 0. 4mm pcb 0. 6mm pcb 0. 8mm pcb 1. 0mm pcb 1. 2mm pcb 1. 5mm pcb 1. 6 mm pcb 2. 0mm pcb 2. 4mm pcb 3. 0mm pcb 3. 2mm pcb 3. 6mm pcb 4. 8mm pcb 5. 6 MM PCB
