How many pads can I print with a solder paste cartridge?
A single solder paste cartridge will allow you to dispense up to 11,000 0603 solder pads.
The official shelf life of the solder paste is 10 months from the time of delivery.
Does solder paste contain lead?
No. The ink and solder wire are lead free. Elemental analysis of our solder paste alloy shows a 0.01% trace amount of lead. This is well below the maximum of 0.07% required by IPC J-STD-006-B for lead-free solder.
How many boards can I print with the ink cartridge?
A single ink cartridge will allow you to print up to 85 "Hello World" boards. This also equates to 100 m of conductive trace at 8 mil width, or 200 cm2 of solid pour. The number of boards you are able to print will depend on size and complexity of the circuits you are building.
The official shelf life of the ink is 4 months from time of delivery.
Does the ink have frequency limitations? Current limitations?
Our calculations show that it should hold up well to about 1 GHz, but we plan on characterizing the ink experimentally in the RF (hundreds of MHz), microwave (GHz), and millimeter-wave (tens of GHz) range over the next few months. We have a full article the performance of the ink under different loads
Does the ink deteriorate over time?
We've tested our printed PCBs under 100mA load for 4 months in ambient, high-temperature (60C) and low-temperature (5C) environments, with no detectable change in performance.
How does this ink compare to standard copper?
The bulk resistivity of our ink is 9.5E-7 Ohms.m and the sheet resistance under typical conditions is 12 mOhms/sq. It is among the best conductive ink on the market and while it is not as conductive as copper it is capable of handling most digital and analog applications.
