As with any chemical system, compatibility with the substrate must be determined on a non-critical area before use. That’s why understanding the best rework and repair methods and materials is so important for those who manufacture, maintain, or repair printed circuit boar. Use it as an economical alternative to nickel or silver paints where extreme conductivity is not required.

Higher currents cause joule heating and a subsequent drop in resistance due to sintering the particles (up to around 8x decrease in resistance if controlled). Photo paper also has other benefits: you can erase ink by scratching a trace away, and you also get the highest conductivity on this surface (<2 ohms/cm). Remove the tip assembly and drop in into a small container of Flux-Off Heavy Duty or another suitable solvent.Import restrictions may apply to certain countries for these products, please check with your local customs office. Engineers, repair technicians, and manufacturers will find that the Circuit Works conductive pen speeds project completion, cuts down rework time and has excellent compatibility with materials used in printed circuit board fabrication. CW220 is used in repairing circuit boards, making prototypes, and reworking by repairing broken traces, joining components, and making smooth jumpers.

If the material needs to be applied in bulk, brushing, banding, or an automatic dispensing equipment may be used. TraceTech board repair system allows technicians of any level to quickly perform quality board repairs in-house, and without using either expensive equipment or time-consuming and unsightly jumpers.Robot Operating System (ROS) is a collection of software frameworks for robot software development, providing operating system-like functionality on a heterogeneous computer cluster.

The CircuitWorks ® Conductive Pen makes high conductivity silver traces on circuit boards instantly. The TraceTech board repair system allows any level of technician to quickly perform quality board repairs in-house without the use of expensive equipment or time-consuming and unsightly jumpers. Techspray offers TraceTech Conductive Pen, which contains highly conductive silver suspended in a liquid polymer. The grey super shield 841AR from MG Chemicals is a nickel conductive paint that protects your electronic devises from EMI and RFIs issues.Chemtronics offers CircuitWorks Conductive Pens which contain a highly conductive material like silver or nickel suspen. As dried polymer dissolves you may see a fine dust of silver collect on the bottom of the soaking container. I've seen a few videos and heard suggestions of people using conductive ink pens to fix traces on a PCB but I've also seen people using a wire to bypass the affected area on the trace.

If the drawn trace must be soldered to, we recommended that tin/lead solder containing 2% silver be used and that the trace is heat-cured at 150 °F (66 °C) for five minutes to produce the most durable trace possible. For functional use, photo paper performs the best because the ink is able to form a continuous film on a smooth surface.Engineers, repair technicians, and manufacturers will find that the CircuitWorks ® Conductive Circuit Pen speeds project completion and cuts rework time. The heavy silver particles tend to settle to the bottom of the pen after sitting for more than 24 hours but will easily redisperse when shaken lightly, used for a few minutes, or simply carried in your pocket. The valved pen tip allows smooth flow with normal writing pressure and is spring loaded to prevent clogging. Once the tip has been cleared of ink, remove it from the solvent and let it drain on a paper towel and stand in the air for 10 minutes to allow the cleaning solvent to evaporate.
