Shenzhen Sunsoar Tech Co.,Ltd

Flexible printed circuit, also known as flex circuits, is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates, such as polyimide, transparent conductive polyester film. Additionally, flex circuits can be screen printed silver circuits on polyester. Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use.ItemsSpecificationsLAYERS1-6 LAYERSBOARD THICKNESSMIN.:10x45MMMAX.:250x1200MMAVAILABLE LAMINATES MATERIALSPI.PET,FR4-PIFINISHED BOARD THICKNESS TOL.±0.01MMFINISHED HOLE DIAMETER(MIN.)0.1MMFINISHED HOLE DIAMETER(MAX)0.6MMNPTH HOLE DIAMETER TOLERANCE±0.025MMPTH HOLE DIAMETER TOLERANCE±0.050MMCOPPER FOIL THICKNESS12UM,18UM,35UM,70UMCIRCUIT WIDTH/SPACING(MIN.)≥0.065MM(1/2OZ)≥0.05MM(1/3OZ)SURFACE FINISHED TYPEOSP.GOLD PLATING,ENIG,TIN PLATING(LEAD-FREE),ETC.FOLD FLASH NI/AUTHICKNESSNI:2.54-9UM  AU:0.025-0.5UMIMMERSION TIN THICKNESS0.7-1.2UMTIN PLATING THICKNESS3-15UMDRILL HOLE POSITION TOLERANCE±0.05MMPUNCHING DIMENSION±0.05MMCERTIFICATESROHS,UL,ISO9001 ETC.A)We have many special material as rogers, teflon, taconic, FR-4 High TG, Ceramic in stock. B)We also provide sourcing components, PCB design, PCB copy, PCB drawing, PCB assembly and so on.C)Stiffeners are applied to flex circuits where additional support is needs such as the areas of component assembly or underneath exposed traces that will be plugged in for connection. Common stiffeners are FR4 and polyimide.Welcome to your inquiry at any time .1.What’s the quality standard your comply with?
