The board is very beautiful, perfect, customer service is awesome, the general problems can be solved, and very patient, to give a thumbs up! Anti-collision package taking into account anti-scattered anti-oxidation, very beautiful. . .
Two days ago to do the board, the quality is quite good, delivery speed, good quality, no reason to not choose here ah.
The board is very fine, the product packaging is also very good, each is an independent packaging, customer service attitude is also very good, very thoughtful service, website pricing system is also very easy to use, very user-friendly design, delivery speed Very fast, very satisfied.
This is the use of proofing materials are made of FR-4, a look that is a good plate, the manufacturer's production process is not to say, done very well, the speed is very fast, on-time delivery, online pricing The system is also very easy to use, you can calculate the price directly to complete the funding orders
Okpcb.net is a professional quick turn PCB prototyping and low-volume production manufacturer located in Shenzhen China. Currently we only accept 4 PCB files format( gerber file, .pcb, .pcbdoc or .cam file format) for PCB fabrication.
In order for us to keep our products and services competitive, we constantly are updating our equipments to better serve our customers. Please send email to firstname.lastname@example.org if your boards are beyond the capabilities listed below.
Click above to order your PCB prototype or low-volume orders online, and you will be asked to upload your PCB files in ( gerber file, .pcb, .pcbdoc or .cam file format) before check out.
|Number of Layers||1-10 layers||For orders above 10 layers, please contact our sales rep.|
|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||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 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.|
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.|
HASL with lead
HASL lead free
|The most popular three types of PCB surface finish. Please 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.
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.
Thanks for reviewing our PCB capabilities. Please upload your PCB files in the format of gerber file, .pcb, .pcbdoc or .cam file when you go through our online purchase procedures. You can also send your Gerber via email (email@example.com), but we strongly suggest you order online on the webpages.
