About the Minimal thickness PCBs. Minimum thickness PCB is a term used to describe that the thickness of a printed circuit board is much thinner than normal PCB. The standard thickness of a circuit board is currently 1.2mm to 1.6mm. The minimum thickness is 0.2 mm to 0.3mm for the majority of circuit boards. Due to the market demand for continually thinner devices, there is a demand for minimum thickness PCB boards such as 0.2 mm, 0.4 mm, 0.5 mm board, ecc. These circuit boards can be used in sensor cards, SIM cards, e altri.
A PCB is an assembly of several layers including di-electric cores, epoxy prepeg and copper, with solder resist coating. A variety of finished board thicknesses can be achieved by combination of various core thicknesses and sheets of prepeg. The different laminate thickness alternatives are given to the customers in the range of 0.008 inches to 0.240 inches and they are 0.2 mm (0.0079 pollice), 0.4 mm (0.016 pollice), 0.6 mm (0.024 pollice), 0.8 mm (0.032 pollice), 1.0 mm (0.04 pollice), 1.2 mm (0.047 pollice), 1.5 mm (0.062 pollice), 1.6 mm (0.063 pollice), 2.0 mm (0.079 pollice), 6.5 mm (0.26pollice), ecc. For a very thin board, it is necessary to only use one layer of core, which limits the number of copper layers to two. we will use 3um or 5um thick copper base to produce the PCBs. maybe 8um on the core. when the PCB finished. the total copper thick is about 8 um to 15um. and More copper layers are only possible by alternating more core and prepeg layers. To produce boards which are mechanically sound, layers should be evenly distributed with an even number of copper layers and an odd number of di-electric layers. Perciò, boards with a high number of layers can reduce their overall thickness by using these thinner core options.
La scelta di uno spessore PCB molto sottile può limitare la scelta delle finiture superficiali disponibili. Ogni finitura superficiale ha un processo di produzione diverso in base alle proprietà del materiale e al metodo di produzione. La nostra finitura superficiale standard in oro a immersione supporta PCB con spessore minimo di 0,1 mm,Tempo di consegna di alta qualità e rapidi. the price will be great!
