What is special specification PCB? How to calculate the weight of PCB?
In Fully Hong, the normal specification PCB refers to FR4, 1.6 mm board thickness, HOZ basic copper thickness, >0.25 mm aperture, >0.15 mm the line width, HASL lead free. Different from above specifications are special specifications.
On average, the weight of 1.6 mm, FR4 PCB is 3.3kg~3.8kg per square meter, depending on the board structure.
In some cases, to avoid transportation damage, weight may be increased for single packed board. Anyway, we will always use the lightest and smallest packaging to save customer's transportation costs.
