Manufacturers of Double sided board
Among all the Chinese 2-layer board manufacturers that cooperate with ALLPCB, the one that provides the most competitive price and best lead time is JDB. The double sided prototype price of JDB is about $12-$60 with lead time of approximate 2-3 days (express service is 24 hours).
Here is the JDB capability for your reference:
Items Capabilities Remarks
Number of Layers 1-10 layers For orders above 10 layers, please contact our sales rep.
Material FR-4 (King Board) For Flex, Rigid-flex, Metal-based (Aluminum etc.,), HDI, Halogen-free, High Tg, etc., please contact sales rep.
Maximum PCB Size(Dimension) 500x1100 mm Any sizes beyond this dimension, please contact us.
Board Size Tolerance(Outline) ±0.2mm/±0.5mm ±0.2mm for CNC routing, and ±0.5mm for V-scoring.
Board Thickness 0.4-2.4mm 0.4, 0.6, 0.8, 1.0, 1.2, 1.6, 2.0, 2.4mm. Please contact us if your board exceeds these.
Board Thickness Tolerance(t≥1.0mm) ±10% Normally “+ Tolerance” will occur due to PCB processing steps such as electroless copper, solder mask and other types of finish on the surface.
Board Thickness Tolerance(t<1.0mm) ±0.1mm
Min Trace 0.1mm/4mil Minmanufacturabletrace is 4mil(0.1mm), strongly suggest to design trace above 6mil(0.15mm) to save cost.
Min Spacing 0.1mm/4mil Min manufacturable spacing is 4mil(0.1mm), strongly suggest to design spacing above 6mil(0.15mm) to save cost.
Outer Layer Copper Thickness 1oz/2oz/3oz(35μm/70μm/105μm) Also known as copper weight. 35μm=1oz, 70μm=2oz, 105μm=3oz. Please contact us if you need copper weight greater than 3oz.
Inner Layer Copper Thickness 1oz/1.5oz(35μm/50μm) Inner copper weight as per customer’s request for 4 and 6 layers. Please contact us if you need copper weight greater than 1.5oz.
Drill Sizes (CNC) 0.2-6.3mm Min drill size is 0.2mm, max drill is 6.3mm. Any holes greater than 6.3mm or smaller than 0.3mm will be subject to extra charges.
Min Width of Annular Ring (Via in Pad) 0.15mm(6mil) For pads with vias in the middle, Min width for Annular Ring is 0.15mm(6mil).
Finished Hole Diameter (CNC) 0.2mm-6.2mm The finished hole diameter will be smaller than size of drill bits because of copper plating in the hole barrels
