Product Description

Barebones PCBs are ideal prototype boards. 

Barebone PCB (Prototype PCB)

They are our most basic printed circuit boards available and are great for testing out your designs without spending a ton of money. These prototype boards are best for using with a hot soldering iron and lots of solder!

These prototype boards come with FR-4 fiberglass (the all-natural yellow color), copper traces, and plated holes with just a little bit of tin over the copper.

When calculating the price, select one size larger than your required board dimensions.

Manufacturing Specifications

Quantity Customer Specified. Larger quantities are quoted here.
Layers 2 (or 1, if desired)
Lead Time 1 Business Day. 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 1 inch. Total board area must be greater than 1 square inch (i.e. smallest square board allowed is 1 x 1 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 None
Silkscreen None
Surface Finish Tin (over 1Oz Cu). Learn more about Surface Finishes.
Soldermask Pad Tolerance N/A
Material Dielectric material is FR-4 with a glass transition temperature of 135 degrees Celsius. However, if a RoHS compliant surface finish is selected, then FR-4 with a glass transition temperature of 180 degrees Celsius will be used. 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 Not Available.
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. Quit Turn for Essential Services during COVID 5 Star Review

    Posted by on 30th Aug 2020

    I tested Bay Area Circuits 30 days into Covid and they delivered. I was then able to steer my customer in that direction 4 months later (instead of going overseas).

    Bay Area Circuits turned my order in the 24hrs quoted and everything arrived right on schedule with no issues. I did not even have to talk to a human, just submitted my Gerber files and on Monday my boards arrived before 9AM.

    If I had to ask for more... it would be an affordable service with solder mask and silk screen. The bare bones boards are ... what they are. With some Mask and Silk they could be a whole lot more.

    But the price and turn sure is great! $8 PCB's in 24hrs, while supporting a local business. That is the win.

  2. Good, solid PCBs 5 Star Review

    Posted by on 2nd Jul 2020

    Good prototyping option, only challenge was UPS shipping, whereas for our location Priority Mail is better

  3. Quick turnaround. Good value. 5 Star Review

    Quick turnaround. Good value.

  4. Great boards 5 Star Review

    Posted by on 26th May 2020

    The boards came out looking great. Being bare tinned boards without soldermask, I had a few spots where I bridged solder and had to be heavy-handed with the iron (because I was an idiot and put way too much ground pour in close proximity to pads -- hint: don't do pours unless you explicitly need it...). The board stood up to that abuse instead of lifting copper as has happened with cheaper boards from elsewhere.

    The one caveat is that the "1 day turn" for any job submitted in the evening ends up being two effective days until it ships.

  5. Great results, as always 5 Star Review

    Posted by on 28th Nov 2019

    Bay Area Circuits is one vendor who I know I can depend on for dependable quality and fast turn around every time.
