About Electro Soft

With an operating history spanning over 30 years, ESI is one of the largest independent contract manufacturers for circuit boards and wire harnesses in the Philadelphia Tri-State area. Electro Soft's experienced team focuses on creating custom electronics manufacturing solutions for clients in aviation, rail, transit, OEM, defense, and more.

We build custom wiring harnesses, cable assemblies, printed circuit boards (PCBs), cabinet assemblies, and military electronics. We’ve become one of the largest independent manufacturers of our kind in the local market. Located just outside of Philadelphia, we employ 32 full-time skilled professionals and occupy over 16,000 square feet of office and warehouse space. All work is done by our diverse staff of assemblers – always in-house, never outsourced.

When you partner with ESI for custom electronics manufacturing solutions, our relationship always includes on-staff engineering support, flexible run sizes, ISO 9001 certification, and just-in-time delivery. Think of our facility as an extension of yours — you’re always welcome here, and we’ll always keep you in the loop. What’s more, we maintain records and drawings for three years for your convenience.

Our Mission

We strive to lead in the Philadelphia Tri-State area for electrical and mechanical contract manufacturing. Electro Soft specifically focuses on electronic components; assembly services for wave and surface mount soldering of circuit boards; and manufacturing of wire harnesses, cable assemblies, and panel assemblies. With this as our specific focus, we will implement the highest standards of integrity and professionalism in every facet of our business.

Our goal is to competitively position your company in today’s market. We can build any benchtop electronic product to your specifications — just provide a blueprint or schematics. As the value leader in electronics contract manufacturing, our strategy is to provide quality and service at competitive prices, yet profitable rates, to exceed our clients’ expectations.

Value, quality, and service are the fundamental force behind our historical and future growth.

Beth DiStefano

Production Supervisor

"I worked for a company that manufactured the boards that went into the bags of money for the banks. The board would explode if anyone opened the bag of money that was loaded onto a truck that was en route to a bank. This was 40 years ago. Ever since then I have been working in the electronics world. "

Karla Trotman

Karla Trotman, Electro Soft’s CEO, has been with the company in one form or another since its founding in 1986. She started out cutting wire by hand and earned 25 cents an hour for sitting at a bench and using a ruler to mark the various lengths she had to make for her father. She graduated to stripping the wires, and eventually to helping operate the wave soldering machine.

Later, in college, Karla was able to put her skills — and business sense — to use. “I noticed that there was one phone in the room for two people to share. On top of that, the cord was too short. Because I grew up around electronics, I had a little business of splitting the phone’s jack and making longer cords so that roommates could each have phones at their bedside.”

She holds a Master’s of Business Administration from Drexel University and a Bachelor of Science in Business Logistics from Penn State University, where she graduated with a minor in the Legal Environment of Business and also received a Purchasing Management Certificate.

Karla lives in Ambler, Pa., with her husband and two boys, along with a 4-year old Shichon named Snickers.
