BEST PCB circuit trace repair kit gives you the tools you need for fast repair and modification of circuit traces. These materials, packaged together and designed by one of premier PCB repair companies, BEST Inc, allows you to meet original PCB quality standards.

The method for repairing damaged circuit traces, which are, supplied in this kit employees the use of copper circuit tracks which are epoxied to the circuit board. These replacement conductors are the same size as the original. This IPC-recommended technique is preferable to making circuit repairs with jumper wires because it most closely duplicates the original fabrication process.

There are (7) different circuit tracks included in this kit making sure you have the track that you need when you need it. Each of the traces as well as the pre-mixed epoxy packs can be purchased separately.

Each Circuit Trace Repair Kit includes the following:

  • Epoxy and Dry Film Circuit Frames - you have the choice!

    Dry Film Adhesive System- A Clean Way Damaged pads and traces can be replaced without the mess of liquid epoxy. The BEST replacement circuit frames with dry-film adhesive backing make this repair process clean and neat. Simply trim out the circuit you need and bond it to the circuit board surface using heat and pressure.

    The BEST dry film is superior to others as it is very clear making it easy for the repair technician to see what is going on to align the pad or trace to the PCB. In addition the BEST dry film is thinner than others making it sit on the PCB post repair closer in height to the original pads or traces making for a neater repair!

    If you are already using a dry film epoxy system see our competitive cross-reference chart here.
  • Epoxy Adhesive System- Proven Reliability BEST testing has shown by using both backside micro etched circuit frames (a BEST standard) and the BEST 2-part electronics adhesive system that the bond strength of repair traces, pads and lands can approach that of the original lands, pads and traces. Even under thermal air-air shock conditions from -50°C to 85°C at a 30 minute dwell time over 200 cycles this adhesive system performed well. In a study summarizing a variety of adhesion techniques for the repair of printed circuit board traces, the 2 part resin-hardner epoxy system has been shown to yield the best results. Furthermore, another study demonstrated that the epoxy method yielded a greater part-pad shear strengths.
