Custom-made PCB board with UL and ROHS certification. 
Our pricing structure is transparent and has no hidden cost in it. Our price is one of the most competitive in the world, and is just a fraction of what other American or European fabricators normally charge you. Even many price-sensitive customers like students and hobbyists largely rely on us for their PCB prototype and fabrication orders. We try our utmost to save your money and time.

2.Company information

With 10+ years in the field of PCB prototype and fabrication, we are promised to meet the requirements of our customers from different industries in terms of quality, delivery, cost-effectiveness and any other demanding requests. As leading PCB manufacturers in China, we pride ourselves to be your best business partners as well as good friends in the every aspect of your PCB needs.


3.Production process
First, is expected to open
1)is expected to open in the process picking - Cut
2)a material purpose
The large size of the incoming cut to produce the desired
3)is expected to open Precautions
① check is expected to open the first pieces of the first pieces of size
② Note aluminum surface scratches and copper surface scratches
③ Note tiered plate edge and burr

Second, drilling
1)the drilling process
Hit the pin - Drilling - check plate
2)the purpose of drilling
Drilling on the plate positioned for subsequent production processes and customer assembly provide assistance
3)drilling Precautions
① check the number of drill holes , empty size
② Avoid scratches sheet
③ Check the aluminum surface of the burr hole position deviation
④ timely inspection and replacement drill bits
⑤ drilling in two phases , a drill : After cutting and drilling tools for the peripheral holes
Two drill : Unit within the tool hole after solder

Third, the dry / wet film imaging
1)the dry / wet film imaging process
Grinding plate - film - exposure - developing
2)dry / wet film imaging purposes
On sheet showing a part of the production line needed
3)dry / wet film imaging Precautions
① Check whether there is an open line after developing
② developing counterpoint is biased to prevent the generation of dry chopped
③ poor attention caused by the plate surface scratch lines
④ can not have the air to prevent the exposure of residual adverse exposure
⑤ After exposure to developing still more than 15 minutes to do

Fourth, the acid / alkaline etching
1)acid / alkaline etching process
Etching - Stripping - drying - Inspection Board
2)acid / alkaline etching object
The dry / wet film imaging portion of the reserved line needed to remove the excess part of the outside line
3)acid / alkaline etching Notes
① Note etching without a net, over- etching
② Note the fine line width and line  
③ Copper surface does not allow oxidation, scratches phenomenon
④ Back to back clean and dry

Fifth, solder printing characters
1)screen printing solder , character flow
Screen - Pre- bake - exposure - development - Character
2)screen printing solder , characters
① solder : do not need to solder circuit protection to prevent a short circuit caused by tin into
② characters: the role played mark
3 )note printing solder , characters
① To check the board if there is garbage or foreign
② Check the stencil cleanliness
③ After printing to pre- bake for 30 minutes or more to avoid the line to see bubbles
④ attention to the thickness and uniformity of the screen
⑤ After pre- baking sheet to cool completely , to avoid damage to the ink stick film or surface gloss
⑥ When placed under the ink -oriented development

Sixth , V-CUT, gongs board
1)V-CUT, gongs board process
V-CUT - gong - tear protective film - Deburring
2)V-CUT, gongs board
① V-CUT: The single- line and the entire PCS PNL leaving a small portion of the plate is connected to the cutting and removal easy to use package
② gong board: the removal of the excess part of the circuit board
3)V-CUT, gongs board Precautions
① V-CUT V process should pay attention to the size , incomplete edges , burrs
② gong board attention cause glitches , gongs knife skewed, timely inspection and replacement gong knife
③ Finally, when Deburring To avoid scratching board

Seventh, OSP
1)the test , OSP process
Line test - withstanding voltage test - OSP
2)test , OSP purpose
① line test : detecting the completed line is working
② withstand voltage test: whether the detection is complete line can withstand the specified voltage environment
③ OSP: Let the line better soldered
3)testing , OSP 's
① How to store after after testing how to distinguish between qualified and unqualified
② OSP finish after placing
③ avoid line damage

Eighth , FQC, FQA, packaging, shipping
1 )the flow
FQC - FQA - packaging - shipping
2 )the purpose of
① FQC full inspection to confirm the product
② FQA verification sampling
③ packaging and shipping to customers on request
3 )attention
① FQC note confirmation of the appearance of the visual inspection process, make a reasonable distinction
② FQA really FQC test standards for sampling to verify
③ To confirm Packing , avoid mixing board , wrong plates and damaged packaging

4.Packaging & shipping
Packaging: standard package.


DHL,UPS, EMS,etc. are the most popular way for shipping, besides we can ship by sea or customer's forwarder.
