  • Prototype as quick as one day
  • Paypal accepted for low-volume

Start with prototype quantities and continue with us to ramp up production level quantities

For PCB prototyping, we are able to manufacture low volume single and double-sided PCBs to complex multilayer PCBs with blind and buried vias at affordable prices.

We supply the fast prototyping service with 24 hours(2 layers) /48 hours(4 layers).
Prototyping stage is the most critical period of time for engineers, students and hobbyists. We not only makes your boards quick, but also makes your job right as well as cost-effective. This greatly reduces your cost and shorten the time for developing your electronic products.
The economical solution for circuit board prototypes with 1, 2, 4, 6, 8 or 10 layers, and a small overall area.

PCB Capabilities - Quick-turn PCB

Items Manufacturing Capabilities Remarks
Number of Layers 1-10 layers For orders above 10 layers,please view the below "Standard PCB" or contact our sales rep.
Material FR-4,Aluminum For Flex, Rigid-flex, Metal-based (Aluminum etc.,), HDI, Halogen-free, High Tg, etc.,please view the below "Standard PCB" or contact sales rep.
Maximum PCB Size(Dimension) 500*1100mm (min 5*6mm) Any sizes beyond this dimension, please view the below "Standard PCB" or contact sales rep.
Board Size Tolerance(Outline) ±0.2mm/±0.5mm ±0.2mm for CNC routing, and ±0.5mm for V-scoring.
Board Thickness   0.2-2.4mm 0.2,0.4, 0.6, 0.8, 1.0, 1.2, 1.6, 2.0, 2.4mm. Please view the below "Standard PCB" or 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 Min manufacturable trace is 4mil(0.1mm), strongly suggest to design trace above 6mil(0.15mm) to save cost.
Min Spacing 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 view the below "Standard PCB" or 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   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
Finished Hole Size Tolerance(CNC) ±0.08mm For example, if the drill size is 0.6mm, the finished hole diameter ranges from 0.52mm to 0.68mm will be considered acceptable.
Solder Mask   LPI Liquid Photo-Imageable is the mostly adopted. Thermosetting Ink is used in the inexpensive paper-based boards.
Minimum Character Width(Legend)   0.15mm Characters of less than 0.15mm wide will be too narrow to be identifiable.
Minimum Character Height (Legend) 0.8mm Characters of less than 0.8mm high will be too small to be recognizable.
Character Width to Height Ratio (Legend) - 1:5 In PCB silkscreen legends processing, 1:5 is the most suitable  ratio
Minimum Diameter of Plated Half Holes 0.6mm Design Half-Holes greater than 0.6mm to ensure better connection between boards.
Surface Finishing   HASL with lead
HASL lead free
Immersion gold,OSP
The most popular three types of PCB surface finish. Please view the below "Standard PCB" or contact us for other finishes.
Solder Mask   Green ,Red, Yellow, Blue, White ,Black

No extra charge (Green, Red, Yellow, Blue)

Silkscreen   White, Black, None No extra charge.
Panelization   V-scoring,
Tab-routing,
Tab-routing with Perforation (Stamp Holes)
Leave min clearance of 1.6mm between boards for break-routing. For V-score panelization, set the space between boards to be zero.
Others Fly Probe Testing (Free) and A.O.I. testing(free), ISO 9001:2008 ,UL Certificate No extra charge.


Testing Procedures

We perform multiple quality assurance procedures before shipping out any PCB board. These include:

  • Visual Inspection
  • Flying probe
  • Bed of nails
  • Impedance control
  • Solder-ability detection
  • Digital metallograghic microscope
  • AOI (Automated Optical Inspection)

Quick turn lead times

For single and double-layer prototype board , we can provide 24 hour turn around times. For multilayer PCBs, the fastest turnaround time depends on the number of layers and quantity.

Service Guarantee:

We make sure to serve each customer professionally, truthfully and friendly to the best of our ability.  We will gladly re-work your project if your project isn’t 100% satisfactory.
