Manufacturing Specifications

Quantity 3
Layers 2 (or 1, if desired)
Lead Time 5 Business Days. To learn more about how lead time is calculated, read this.
Maximum Board Size Up to 50 square inches per board (for this specific offer). Maximum board dimension is 22.5 inches (maximum manufacturing capability).
Minimum Board Size Minimum dimension in height or width is 0.35 inches. Total board area must be greater than 0.4 square inches (i.e. smallest square board allowed is 0.64 x 0.64 inches).
Minimum Trace and Space Etching resolution is 0.005” minimum trace width, 0.005” minimum space width.
Inner Layers N/A. There are no inner layers for this product.
Soldermask Color = Green. Top and Bottom
Silkscreen Color = White. Top and Bottom
Surface Finish HASL (Lead). Learn more about Surface Finishes.
Soldermask Pad Tolerance Pads on the soldermask layers are grown by 0.003” on all sides. As a result, very fine pitch surface mount components may not include any soldermask between the pins.
Material Dielectric material is FR-4 with a glass transition temperature of 135 degrees Celsius. Outer layers begin with 0.5 ounces of copper, then during through hole plating, up to 1 ounce of copper may be added to the outer layers. Thus, the total outer layer copper is between 0.0017" and 0.0021". If the board is 1 layer or does not have plated through holes, then the outer layer copper may be as low as 0.0014”, since less plating is required. The total board thickness will be 0.062".
Dielectric Constant The dielectric spacing 0.057” with a dielectric constant of 4.58 +/-0.2.
Annular Ring Minimum annular ring must be at 0.005” or greater.  Calculate annular ring by subtracting the diameter of the via hole from the diameter of the via pad and dividing by two.
Plated Holes Boards are manufactured with 2 (or 1) copper layers. All holes with copper pads on the top and bottom are plated through, while holes without a copper pad on the top or bottom layer are non-plated. Holes with a copper pad on one outer layer but not on the other are not accepted.
Hole Sizes & Quantity All hole sizes between and including 0.010” and 0.247” are available, up to tolerance. Limit number of holes to less than 50 per square inch.
Hole Tolerance These sizes are the finished hole diameters after plating. Holes 0.014” or smaller may be filled with solder and can only be used as via. The tolerance of 0.015” to 0.020” holes is +0.003 / -0.005. The tolerance for the other hole sizes are +/-0.003”.
Hole Location Tolerance Hole location tolerance is +/-0.003”.
Minimum Hole Distance The distance between plated holes of different nets is dictated by annular rings and trace/space. Plated holes of the same net and non-plated holes should be at least 0.005” apart.
Internal Slots and Cutouts Not Allowed
Perimeter Slots Board perimeters are cut to shape using a 0.078” router bit. Slots in the perimeter must be 0.100” or wider. Narrower slots may not be cut correctly.
Perimeter Routing The edges of the board are cut with an accuracy of +/-0.010”. A minimum of 0.020” blank space is recommended between the perimeter and all features on the board. Copper features, vias, and any other design element placed closer than 0.010” to the board’s edge may be routed off.
Temperature All boards can survive standard reflow, while RoHS compliant boards are able to survive RoHS reflow. The maximum operating temperature is 125 degrees C.
Electrical Test Optional
Other Arrays (Tab Rout, Breakaway Tabs, Mouse Bites, etc), Beveled Edges, Blind/Buried Vias, Castellated Edges, Countersinks/Counterbores, Controlled Impedance, Edge Plating, and Scoring are NOT available with this product option. When required, please request a custom quote here.

  1. The Best Service and Product around!! 5 Star Review

    Posted by on 20th Jan 2021

    This was my 4th or 5th order from BAC using this 2 layer special. Somehow, they seem to look better each time. The quality is top notch, the price is great, and their service is excellent! Even during COVID slowdowns, I got my PCBs very quickly. For USA made PCB's, this is the place to go!!
    I have tried others and BAC is head and shoulders above the rest.
    Highly recommended.


  2. No complaints 5 Star Review

    Posted by on 18th Sep 2020

    I've done a few boards with Bay Area Circuits. I've always had a pleasant experience in terms of quality and speed. The PCBs even finishes earlier than expected sometime.


  3. Good boards, only one gripe... 4 Star Review

    Posted by on 22nd Jul 2020

    Pricing could be a bit more competitive. With that said, BAC still does a nice job. They're the ones to talk to if you don't want to risk shipping delays from China (due to the COVID nastiness).


  4. superb 5 Star Review

    Posted by on 7th May 2020

    2 day turnaround instead of 5. No problems with boards. Excellent quality.


  5. Great value and great service 5 Star Review
