What Is Build-to-Print Test System Manufacturing and When Is It the Right Choice?
Testing…testing…is this thing on? All joking aside,...
Founded in Central Indiana, Ball Systems partners with global manufacturers to build, replicate, and support custom electrical test systems.
Our execution-first approach blends decades of practical engineering experience with manufacturing discipline to keep systems running and simplify the lives of the engineers we serve.


Ball Systems builds and delivers custom electrical test systems and build-to-print assemblies for production-critical environments.
A universal test platform replaces fragmented, one-off testers with a more maintainable, production-ready approach. By standardizing test infrastructure and reducing unnecessary complexity, engineers gain systems that are easier to support and scale, making their lives easier in the process.
