Gold Fingers

Gold Fingers allowed on HASL finish only

Standard Gold Thickness

Minimum Hole size

Down to 6 mils (0.006") finished hole size allowed.

Maximum Hole size

Plated holes: 246 mils (.246"). Non-plated holes: 199 mils (0.199").

Maximum Hole Density

Instant quote may not be available if hole density exceeds 100 holes/sq inch (Total holes on a board/Area of board) Our Customer Service Agent may ask for more details before quoting designs with such high hole-density.

Via-in-Pad features

We allow via-in-pad features on your board. The turn time for such jobs will be minimum 7 days (for Turnkey).

All vias in such boards will be filled with non-conductive filling.

Minimum width of annular rings

6 mils (0.006") (We need this minimum annular ring width on your design to ensure there are no "breakouts" on the pads in the manufactured board)

Controlled Dielectric

In our RPS offering, we don't allow you to specify dielectric thicknesses. However, you can get controlled impedance features using our standard stackups.

Controlled Impedance

This means in your design, you are specifying the width of certain traces and spacing to achieve a specific resistance.

In your impedance modeling, use the Dk for material 370HR.

We expect that in your fab drawing, you will have a Impedance table that CLEARLY identifies the Target Impedance(s), the Layer(s) on which they exist and the specific Trace Widths / Spaces to be controlled. See a sample format for Impedance Table.

Do note that in this online service, our Controlled Impedance offering has certain limitations:

• Only offered for boards up to 6 layers
• Only available with +/- 10% tolerance
• You can have controlled impedances on up to 4 different layers on your board
• On any layer you can have up to two different controlled impedances
• Our engineers will meet your controlled impedance requirements using our own stackup.
  (All we need is your controlled impedance info. We do not need and may not use any specific controlled dielectric information you provide)

If your Controlled Impedance requirements exceed this spec, please ask for a Custom Quote.

Counter bores/ Counter sinks

Available.

Internal Cutouts/Slots and Notches

Up to 10 plated slots allowed per board

Up to 10 non-plated slots allowed per board

Up to 10 cutouts allowed per board

Up to 10 notches allowed per board

(If any of the above allowances are exceeded in your design, we can still process it for a minimum $100 extra lot charge on your order. We will get your approval before doing so.)

Minimum Inside Radius (for any notch, cutout or slot) = 20 mil (0.02")

Minimum Width (of any notch, cutout or slot) = 40 mil (0.04")

Multiple Parts

We expect to see a single image of a single PCB, and the vast majority of the orders we see comply with this. However if your files do have more than one part on it, we will charge you $100 extra on the order.($100 Lot charge)

Soldermask process

Silkscreen/ Legend

Legend Colors available: White, Black, Yellow. Both sides allowed.(Legend should have minimum 5 mils (0.005") trace width).

Logo

Allow Vendor Markings on board: Vendor markings include Company Logo, UL marking, Flammability, etc. Such vendor markings will be put in Silkscreen.

Electrical Testing

Electrical testing is mandatory for all boards. This is the only way for any PCB manufacturer to ensure the product shipped has zero shorts or opens.

Visual inspection can never be 100% effective. Especially, if the defect is under the solder mask, electrical test is the only way to catch it.

Shipping options

FedEx, UPS, Will Call. You can use your own Fedex/UPS Account number. International Shipments allowed. All duties/customs are responsibility of the customer. See shipping charges here.

Payment terms

Credit Card (Purchase Order allowed only for select customers who have set up credit terms)

Additional requirements

For 4 Layer or more orders, please include stack-up information. Please be available to clarify any discrepancies by providing your 24 hour contact number. IMPORTANT NOTE: RPS are manufactured to IPC-6012 Class 2 - No Coupon specifications. (RPS are not appropriate for ITAR, Mil-spec, Class 3 jobs-- please get a custom quote for those).

RESTRICTIONS (for some special boards, instant pricing is not available, we will send you a custom Quote instead)

For PCBs, special features like Milling, Blind/Buried vias, Mixed Copper layers, etc., cannot be instantly priced online. However, please use the online price matrix anyway and press the CLICK HERE link. A Customer Service Agent will contact you and get you a quote as needed.

For Assembly, our online labor quote is for RIGID boards only with below specifications.

• Minimum passive component size allowed is 0201.
• Minimum pitch allowed is 0.4 mm for regular SMT devices (For BGA the minimum pitch allowed is 0.5 mm).
• Maximum number of thru hole components (per board) is 20.
• Minimum component pad size must be 8 mil X 8 mil or 8 mil diameter.

Furthermore, it does not include the following:

1. Assembly of Flex or Rigid-Flex boards.
2. Assembly of special items like PEM nuts, Turrets Terminals, Rivets, and Press-Fit connectors.
3. Special assembly processes like: Wire-Bonding, Conformal Coating, Underfills, Staking, POP assembly, wires & cables assembly.
4. Assembly Rework like cutting traces, soldering wire jumpers & cables onto the boards.

This Rapid Prototype Service(RPS) works for most of boards and assemblies typically prototyped.
If you know that your boards have special features (buried vias, metal core, special materials etc) that do not meet the RPS restrictions, you can ask for a custom quote here

OUR RIGHT TO REFUSE AN ORDER

PCB FAB EXPRESS reserves the right to refuse any RPS order within 1 business day. This is a rare occurrence, but may happen, say, if your board design or assembly has special complexities that are not commensurate with the price quoted online.
