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, etc. These circuit boards can be used in sensor cards, SIM cards, and others.
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 inch), 0.4 mm (0.016 inch), 0.6 mm (0.024 inch), 0.8 mm (0.032 inch), 1.0 mm (0.04 inch), 1.2 mm (0.047 inch), 1.5 mm (0.062 inch), 1.6 mm (0.063 inch), 2.0 mm (0.079 inch), 6.5 mm (0.26inch), etc. 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. Therefore, boards with a high number of layers can reduce their overall thickness by using these thinner core options.
Choosing a very thin PCB thickness may limit the choice of surface finishes available. Each surface finish has a different manufacturing process based on the material properties and production method. Our standard immersion gold surface finish does support 0.1mm minimum thickness PCB,High quality and fast lead time. the price will be great!
