Our MiniBoard Service is our least expensive PCB option. These are the same high quality PCBs as our other manufacturing services, but with a fixed size and quantity. By standardizing the size and number, we can offer these boards at a very low price.
Cutoff Time for all services is 2 PM Eastern Time. We only manufacture orders placed via our ExpressPCB Software.
MiniBoardPro boards are two layer boards with all holes plated through. They include the solder mask layers giving the boards a green color and a very professional look. Printed on the top surface is a white silkscreen layer showing the component outlines and text.
- MiniBoardPro boards are 2 layer PCBs that include the solder mask and silkscreen layers.
- For a fixed price of $71, you will receive 3 identical boards.
- The board’s size must be 3.8 x 2.5 inches.
- Orders submitted Monday through Friday by 2:00pm ET are shipped in 2 business days.
|Lead Time||2 day|
|Maximum Board Size||Boards are cut in a rectangle 3.8 x 2.5 inches.|
|Minimum Board Size||Boards are cut in a rectangle 3.8 x 2.5 inches.|
|Panelize Muliple Boards||Multiple circuits can be pasted together on a single board, but we do not cut them apart. The perimeter of a board cannot include long slots as they can cause manufacturing problems. We are not responsible for any defects that are a result of routing multiple circuits on a single board.|
|Minimum Trace and Space||Etching resolution is: 0.006″ minimum trace width, 0.006″ minimum space width.|
|Inner Layers||No Inner Layers|
|Solder Mask||Top and Bottom|
|Solder Mask Pad Tolerance||Pads on the solder mask layers are grown by 0.003″ on all sides. As a result, very fine pitch surface mount components may not include any solder mask between the pins.|
|Material||Our 2 layer laminate is .059" FR-4 epoxy glass which includes .0007" copper on each side (industry standard 1/2 ounce copper base). We plate an additional .001" copper on the surface after drilling and imaging, resulting in a copper thickness on the surface of ~0.0017″.|
|Dielectric Constant||The dielectric constant of our FR-4 laminate ranges from 4.2 to 5.0.|
|Plated Holes||Boards are manufactured double-sided with all holes plated-through.|
|Maximum Hole Count||The maximum number of holes allowed in a MiniBoard is 350.|
|Holes||Twenty-three hole sizes are available: 0.014″, 0.020″, 0.025″, 0.029″, 0.033″, 0.035″, 0.040″, 0.043″, 0.046″, 0.052″, 0.061″, 0.067″, 0.079″, 0.088″, 0.093″, 0.100″, 0.110″, 0.125″, 0.141″, 0.150″, 0.167″, 0.192″, 0.251″. Hole sizes other than those listed are not offered.|
|Hole Tolerance||These sizes are the finished hole diameters after plating. The 0.014″ hole may be filled with solder and can only be used as via. The tolerance for the 0.020″ hole is +0.003 / -0.005. The tolerance for the other hole sizes are +/- 0.004″.|
|Hole Location Tolerance||Our hole location tolerance is +/- 0.005”. As such, the tolerance between two holes would be +/- 0.010”.|
|Minimum Hole Distance||A minimum of 0.021″ space must remain between adjacent holes. For example, the center-to-center distance between two pads with 0.020″ holes must be 0.041″ or greater.|
|Internal Slots and Cutouts||None|
|Perimeter Slots||No Perimeter Slots|
|Perimeter Routing||The edges of the board are cut with an accuracy of +/- 0.015″. A minimum of 0.020″ blank space is recommended between the perimeter and all features on the board. Traces placed closer than 0.015″ to the board’s edge may be routed off.|
|Temperature||The maximum operating temperature is 125 degrees C.|
