Double layer PCB countersunk head halogen free material
Double-sided PCBs are the same as single-sided PCBs, but the difference is they have two sided traces with a top and undermost caste. Double-sided PCBs can mount conductive bull and factors on both sides of the published circuit board so that the traces can cross over each other. So it leads to a advanced density of boards without the need of point-to- point soldering. So it’s delicate to fabricate the double-sided PCBs because they are more complex than single-sided PCBs. Still, it’s better to use the double-sided PCBs compared to single-sided PCBs. https://www.ymspcb.com/cheap-pricelist-for-china-high-quality-countersink-pcb-prototype-copper-printed-circuit-board-good-technology-board.html Parameters Layers 2 Double sided PCB Thickness1.6 mm Base Material S1150G Halogen Free Mininum Hole Size ：0.2 mm Minimum Line Range/ Concurrence ：0.15 mm/0.15 mm Size ： 250 mm × 180 mm Aspect Rate ： 8 1 Face treatment ： ENIG Special Fashion Co...
