RAPID PROTOTYPE ASSEMBLY service at PCB FAB EXPRESS
RPA PCB and Assembly Specifications

Summary

Our RPA service enables ultimate speed and convenience for your Assembly prototyping.

PCB Fabrication: Instantly quote and order standard technology, rigid PCBs up to 8 layers, with standard materials and finishes. These are single lamination PCBs (i.e., no blind/ buried vias allowed). PCB Fabrication will be done to IPC-6012 Class 2 specification.

PCB Assembly: Instantly quote and order Consigned, Turnkey and Partial-Turnkey assembly though the RPA service. (Get instant BOM pricing also!). Assembly of Rigid PCBs only, not flex or rigid-flex! PCB Assembly will be done to IPC-A-610 Class 2 specification.

For PCBs: We prefer 274X Extended Gerber format. If your file is not in 274X, send an Aperture file. Please see FAQ below for what files to include.

For Assembly: You will need to upload your BOM (excel format) online for quoting. In the final package we will need Assembly Drawing and XY data also.

2,3,4,5 and 10 business days from order date. When will my boards ship if I order today?

5PM PST

From 1 PCB to 100 PCBs. Some restrictions may apply for large quantities on Quick Turns.

Maximum Area allowed for a board is 150 square inches

Maximum X or Y dimension allowed is 15.9" and minimum dimension allowed is 0.5"

FR4, FR4-06, Polyimide, FR4-Lead Free Standard materials are instantly quoted online. Exotic materials may be quoted by a Customer Service Agent offline.
Please note that RPA service is for Rigid PCBs only. For Flex or Rigid-flex PCBs, please get a custom quote directly through a PCBFabExpress sales person.

Almost all standard thicknesses including 0.125", 0.93", 0.062" and 0.031". (certain layers may be limited to certain standard thicknesses)

The tolerance for thickness in RPAs is +/- 10% of nominal thickness for boards down to 0.031 thick For boards less than 0.031 thick the Thickness Tolerance is constant at +/- 0.003 (+/- 3 mils).

Arrays are allowed in RPA product. But we will NOT create the arrays for you- your file has to have the array as a single-up image! When quoting, you will have to enter the Array dimensions, how many boards per array, and Individual board dimensions.
For PCB quotes purpose always enter the quantity of individual boards (NOT the quantity of arrays).

Arrays may have Scoring or Route and Retain.

Down to 4 mils (0.004") minimum trace/space!

Minimum air-gap of 0.004" (space between any two copper features)

Minimum annular ring 0.005" (applies to both plated and non-plated holes)

Minimum inner layer drill to copper spacing .013" (applies to both plated and non-plated holes)

Surface pattern: Nominal 1 oz./sq foot. (0.0013" to 0.002") (33 microns to 51 microns)

Surface pattern: Nominal 1 oz./sq foot. (0.0013" to 0.002") (33 microns to 51 microns)

0.0008" to 0.0012" (20 microns to 30 microns)

HASL(Solder), Lead-Free HASL, Immersion Gold.

Gold Fingers allowed on HASL finish only

Gold Finish Gold Thickness Nickel Thickness Palladium Thickness
Soft Bondable Gold 30 μin (0.76μ) - -
Immersion Gold 2-5 μin (0.05μ - 0.125μ) 125 μin - 250 μin -
Hard Gold 31.5 μin (0.80μ) - -
ENEPIG 1-2 μin (0.025μ - 0.5μ) 125 μin - 250 μin 4 μin - 8 μin

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

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

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.

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.

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)

For more details on Annular Ring requirements click here.

Not offered in RPA.

Available.

Up to 3 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")

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)

Solder Mask is available in Green color only. It is allowed on both sides. In our RPA service, we only offer LPI solder mask.

Please follow the guidelines given below.

LPI Solder Mask (Green)

Only White color legend is offered. Legend can be on both sides. Legend should have minimum 5 mils (0.005") trace width.

Only White color legend is offered. Legend can be on both sides. Legend should have minimum 5 mils (0.005") trace width.

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.

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

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: RPAs are manufactured to IPC-6012 Class 2 specifications. (RPAs are not appropriate for Mil-spec or Class 3 jobs-- please get a custom quote for those). Also, if your design has ITAR considerations, do mark the ITAR radio-button when getting quote.

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 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.

If any of these is required, such services will be quoted separately by a Customer Service Agent.

PCB FAB EXPRESS reserves the right to refuse any RPA order within 1 business day. This rarely ever happens, but may happen, say, if your board design or assembly has special complexities that are not commensurate with the price paid online.
