Coppper Base:Thermal Conductivity ,Copper Structure...
Rogers / PTFE Teflon:Material Type ...
3. Layer(s):*
Number of Copper layers
4. Board type:*
The full board are by only one single board or be arrayed with the same or different PCBs
5. PCB Size(Length:MM)
the PCB length , unit is MM
6. PCB Size(Width:MM)
the PCB Width , unit is MM
7. Quanlity :*
Quantity of single or panel boards
8. Break-away Rail:
Rail at the edge of panel boards in order to fix the panel boards on assembly machine more easily
9. PCB Thickness (MM):*
Thickness for the finished PCB
10. Solder Mask Color:*
Color of the protective solder mask .
Usually green color, if you choose other color, the lead time and price will be different.
11. Silkscreen:
Color of the silkscreen
12. Finished Copper Weight:
The minimum amount of copper thickness on the external layers includes copper base and plated copper
13. Min. Trace / Space Outer:
Minimum width of any conductors/Minimum distance between any two adjacent trace
14 Min. Drilled Hole:
Minimum diameter of holes
15. Via Process :
What is the main reference to process vias by SjcEMS?
1.If you submit gerber file, then we process via exactly according to your file. The three options you chose will be ignored then.
2.For .PCB and .PCBDOC files, it is hard to confirm the via attribute, so we will process via according to the options you selected.
16. Surface Finish:*
Extra process to exposed copper to help solderability.
Usually HASL, if you choose LEAD FREE OR ENIG, the lead time and price will be different.
17. Electrical Test:
We will do 100% testing by flyingprobe and E-test machine
18. Impedance:
For designs that require tightcontrol on the circuit impedanceincluding modeling andverification testing
19. Other Special Requests:
20. Gerber files(.Zip, .rar )
Gerber files are files that all circuit design software can produce.It has the effect of assisting in improving quality by arranging production preparation, manufacturing, and testing processes.
Gerber file is the standard format of EIA and is divided into RS274-D and RS274-X. RS274-X is an extension file of RS274-D. it is better to provide the Gerber file of RS274-X.
