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, e outros.
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 polegada), 0.4 mm (0.016 polegada), 0.6 mm (0.024 polegada), 0.8 mm (0.032 polegada), 1.0 mm (0.04 polegada), 1.2 mm (0.047 polegada), 1.5 mm (0.062 polegada), 1.6 mm (0.063 polegada), 2.0 mm (0.079 polegada), 6.5 mm (0.26polegada), 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. Portanto, boards with a high number of layers can reduce their overall thickness by using these thinner core options.
A escolha de uma espessura de PCB muito fina pode limitar a escolha dos acabamentos de superfície disponíveis. Cada acabamento superficial possui um processo de fabricação diferente com base nas propriedades do material e no método de produção. Nosso acabamento de superfície dourado de imersão padrão suporta PCB de espessura mínima de 0,1 mm,Alta qualidade e prazo de entrega rápido. the price will be great!
