SPECIAL OFFER: With every Barebones PCB purchase, you will receive a $50 discount code via email that you can apply to your next 2, 4, or 6 Layer Instant Quote order.
Barebones PCBs are ideal prototype boards.
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.

|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 size must be less than 22.5 inches in height and 16.5 inches in width (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.|
|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.|
|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.|
|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. Traces 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||Controlled Impedance, Blind/Buried Vias, Countersinks/Counterbores, Arrays, Scoring, and Beveled Edges are NOT available with this product option. When required, please request a custom quote here.|

Very fast turn; sent more boards than I had actually ordered; always very high quality; reasonable price...what's not to love!

I always use BAC for quick prototypes. The one day turnaround is the best out there, especially for the price.

I submitted my gerber files for a simple, 2 layer PCB on a Monday and had 3 finished boards on Wed. Not bad! Quite a nice service.

These guys are the best. You really can't beat their prices and turn times. The proto boards work great and are ready in 24 hours. Their customer service and support is top-notch. Thanks for another great experience!

the board design was great but the traces were only slightly less heat conductive than solder, it was easy to melt off a trace if I were not careful.
