M Specialties LLC’s experience in the design and manufacturing of printed circuit boards is unmatched by anyone in the industry. Our years of experience includes work with mixed signal, high speed digital and RF applications. We design our boards to be 100% compliant with each tester manufacturer guidelines. We create all of our templates from the Tester manufacturers specifications, and have compiled a wide variety of templates over the last 35 years.

When it comes to manufacturing boards, we use only qualified partners who deliver quality products on time; while utilizing the best materials and practices.

We are committed to meeting your requirements at every stage of the process; from characterization to production.


We use the latest CAD software tools such as Cadence Allegro and Mentor PowerPCB to design and layout our boards.
