PCB Forum Understand What You Need

January 2, 2018 0:00:28 Reply

You could look at other aspects of developing with Arduino such as Printed Circuit Boards (PCB), design a circuit, develop using a breadboard/prototype board , experiment with the circuit, fine tune the design, draw circuit using a CAD program, design a PCB, send files to PCB manufacturer, solder components, test PCB with components, tweak if necessary, share your experience with others. have a look at this PCBindex's PCB Forum!

3Thickness Tolerance( t≥1.0mm)± 10%+10% will occur for the technologies like electroless copper, solder mask and pad plating.
4Thickness Tolerance( t<1.0mm)±0.1mm+0.1mm will occur for the technologies like electroless copper, solder mask and pad plating.

7Max. Dimension550x650mmStandard dimension is 550*650mm
8Dimension Tolerance(Outline)±0.15mm±0.15mm for CNC routing, and ±0.5mm for V-scoring
9Min. Trace4mil(0.1mm)Min. trace is 4 mil. More than 6 mil is recommended to save cost.
10Min. Spacing4mil(0.1mm)Min. spacing is 4 mil. More than 6 mil is recommended to save cost.
11Finished Outlayer Copper35um/75um(1 OZ/2 OZ)Also known as copper weight. 35μm=1oz, 70μm=2oz
12Finished Inerlayer Copper35um35μm=1oz
13Drill Size0.25--6.3mmMin. drill size is 0.25mm, Max. drill size is 6.3mm. Any holes greater than 6.3mm will charge extra fee.
14Annular Ring≥0.153mm(6mil)Annular ring surrounded by traces should be equal to or larger than 0.153mm(6mil).
15Finished Hole Size0.25--6.5mmFor the plated hole wall, the finished hole size is smaller than the one in file.
16Hole Size Tolerance±0.075mmeg. For the 0.6mm hole, the finished hole size between 0.525mm to 0.675mm is acceptable.
17Solder MaskLPILiquid Photo-Imageable Solder Mask
18Min. Character Width≥0.15mmCharacters width less than 0.15mm will be unidentifiable.
19Min. Character Height≥0.8mmCharacters height less than 0.8mm will be unidentifiable.
20Character Width to Height Ratio1:51:5 is the best ratio for producation.
21Trace to Outline≥0.3mm(12mil)Rounting: Trace to Outline≥0.3mm; V-scoring: Trace to Outline
22Panelization without space0For V-scoring panelization, set the space between boards to be 0.
23Panelization with space1.6mmFor Rounting panelization,set the space between boards to be ≥1.6mm.
24Polygon Pour with PadsHatchPlease attention that we will apply Hatch to do Polygon Pour if your PCBs designed with Pads.
25Slot Drawing with PadsDrill Drawing LayerWith many unplated grooves, please draw them in Drill Drawing Layer.
26Protel/dxp Override LayerSolder LayerDo not mistake the Paste Layer as Solder Layer.
27Protel/dxp Keepout LayerKeepout Layer/Mechanical LayerChoose one from Keepout Layer or Mechanical Layer as outline.
28Min. Half Hole Diameter0.6mmHalf hole is a special technology, so half hole diameter should be greater than 0.6mm.
29Soldermask Bridge0.1mmSolderbridge is available but it will charge extra fee.
