How to Order

We encourage customers to initiate their projects via our online inquiry system. You can complete the process in four simple steps.

Step 1: Submit Your Inquiry Click the “Get a Quote” button on our home page, upload your Gerber file, and input the full details of your specification requirements.

Step 2: Engineering Audit Your inquiry will be sent directly to our internal system for an engineering review. Our team will evaluate the files and contact you to ensure all technical specifications are met.

Step 3: Quote Confirmation & Payment Once the audit is complete, we will send the formal quotation and payment instructions via email. You can complete the payment in the “Awaiting Payment” zone or confirm with us directly by replying to the email. (For payment inquiries, please contact: info@pcbonline.com)

Step 4: Track Your Progress After the order is placed, you can track its production progress online at any time. Our engineers will perform a final review before production and notify you of any discrepancies.

Before payment, you can inform our online customer service on the right of every page to change the quantity and price.

For the placed order, we will arrange the production for the first time, so the quantity cannot be modified, but if you want to add quantity, you can place another order. We will try to arrange delivery to you together.

To avoid any unnecessary delays, please ensure the following information is provided before submitting your order:

1. PCB Material
   Please specify the material to be used, including but not limited to FR-4, aluminum, FPC, or rigid-flex PCB.

2. PCB Layer Count
   Please confirm the number of layers required, such as single-sided, double-sided, 4-layer, 6-layer, or 8-layer PCB.

3. Board Thickness
   Please specify the board thickness, for example: 0.8mm, 1.0mm, 1.2mm, 1.6mm, or 2.0mm.

4. Copper Thickness
   Please confirm the copper weight/thickness required, such as 1oz, 2oz, or 3oz.

5. Surface Finish
   Please specify the preferred surface finish, including HASL Lead-Free, ENIG (Immersion Gold), Immersion Tin, Immersion Silver, or OSP.

6. Solder Mask Color
   Available colors include green, red, black, white, and others upon request.

7. Silkscreen Color
   Available colors include white, black, green, red, and others upon request.

Manufacturing & Engineering Notes

1. All holes without electrical connection, including holes equal to or larger than pad size and holes without pads, will be manufactured as NPTH holes by default. Any conflicting hole requirements in other documents will be ignored.

2. The minimum non-plated slot width is 0.8mm, and the minimum plated slot width is 0.4mm.
   If the design is smaller than these specifications:

• NPTH slots will be automatically enlarged to 0.8mm.

• PTH slots below specification will require engineering confirmation.

3. For vias used only for electrical conduction, if spacing limitations exceed manufacturing capability and the vias cannot be moved, we may reduce the hole size by less than 0.1mm.

4. Boards with castellated holes (half-holes) may have slight copper burrs or minor copper pulling at the board edge.
   Requirements:

• Minimum hole size: 1.0mm

• Maximum panel quantity per unit: 5 pcs

5. If a plated hole has a pad on only one side, we will add an annular ring of +0.127mm on the opposite side when space allows, unless the hole is designed on the GKO/GM1 layer, in which case it will be treated as NPTH.

6. Incomplete same-net connections or traces connected with widths below 4mil may cause open circuits during production. Please ensure all same-net traces are fully connected.

Solder Mask

7. If solder mask openings conflict with paste/opening layers:

• Larger solder mask openings will be produced according to the solder mask layer directly.

• Smaller solder mask openings will require engineering confirmation.

8. If only one side of a PTH hole has solder mask opening, we will add a solder mask dam on the opposite side to prevent ink entering the hole.

9. For AD/Protel files, VIA treatment follows the software settings.
   For PADS, Gerber, and other formats, VIA treatment follows the Gerber/file design only. Any additional written requirements inside PCB files may be ignored unless specifically noted.

10. Via plugging without special requirements will follow standard green-light-visible plugging specifications.

Silkscreen & Marking

11. Production marks and internal tracking numbers may be added to the panel or board area for identification purposes unless otherwise specified.

12. Silkscreen limitations:

• Line width below 6mil or text height below 36mil: HD silkscreen not guaranteed.

• Line width below 5mil or text height below 30mil: complete clarity not guaranteed.

• Line width below 4mil or text height below 28mil: blurred text acceptable.

13. Text placed on pads may be clipped or partially removed during production.

14. Mirrored/reversed text caused by original design files will not be accepted as a manufacturing issue.

Surface Finish Upgrade

15. Surface finish may be automatically upgraded during production integration:

• HASL → Lead-Free HASL → ENIG
  Higher-grade finishes may replace lower-grade finishes to improve production efficiency.

Board Outline & Panelization

16. Milling edges and slots must maintain at least 0.25mm clearance from pads.
    V-CUT clearance requirements:

• ≤0.8mm board thickness: 0.3mm

• 0.8–1.0mm: 0.35mm

• 1.0–1.6mm: 0.4mm

• 1.6–2.0mm: 0.5mm

Copper near the edge may be automatically removed to avoid exposed copper unless otherwise specified.

17. Boards with V-CUT crossing milled areas may have slight burrs on the board edge.

18. Small boards should be panelized:

• Single V-CUT direction: panel dimension >75mm

• Dual V-CUT directions: >75×75mm

• Ultra-small boards (≤20mm side): >100×100mm

19. Sharp internal panel corners with openings below 0.8mm may produce unavoidable burrs.

20. Orders with process rails may include:

• 4 × 2.0mm NPTH tooling holes

• 4 × 1.0mm fiducial marks

Single-board shipments will not include tooling holes or fiducials.

21. Only GKO and GM1 layers are recognized as outline/mechanical routing layers unless otherwise specified.

22. Square slots may include corner relief holes:

• Standard relief hole: 0.5–0.8mm

• Slots narrower than 1.2mm may not include relief holes.

Stackup

23. For multilayer boards, please provide the stackup sequence clearly.
    Priority:
    Order notes → Gerber naming → factory standard.

24. Unless stackup confirmation is specifically requested, production will follow our standard stackup.
    Impedance compensation within ±2mil trace adjustment may be processed directly without confirmation.

Design Software

25. PADS copper filling will default to Hatch mode.

26. If both PCB source files and Gerber files are provided, Gerber files take priority.
    Priority order:
    Production files → Gerber files → PCB source files.

27. Supported PCB software:

• Protel series

• Altium Designer (AD)

• PADS

For AD designs, Gerber export is strongly recommended to avoid compatibility issues.

28. PADS files may require internal layer redefinition before Gerber generation. Any discrepancies caused by layer remapping will not be considered manufacturing responsibility.

Ordering Requirements

29. Any requirements written inside ZIP packages, Gerber comments, or internal documents are considered invalid.
    All manufacturing requirements must be clearly stated in the order remarks.

Board Thickness

30. For single/double-sided boards, internal core thickness may be produced as X-0.1mm. Boards without copper balancing may have thinner finished thickness.

Gold Fingers

31. Gold fingers may contain routing lead marks by default.
    If lead marks are not acceptable, please clearly specify:
    “No routing lead marks allowed on gold fingers.”
