RPA PCB and Assembly Specifications


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?


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)
