TJM Electronics ( offers both SMT and through-board quality-certified PCB assembly, as well as electro-mechanical assembly, and electronics prototyping for the most demanding industries, such as aerospace and defense, medical, industrial, led lighting and prototype electronics needs. It has been AS9100D certified since 2020.

TJM Electronics offers high quality PCB assemblies at automated pick and place speeds of up to 45,300 cph (components per hour), and fine pitch down to 0.3mm. “Our smart automated assembly lines give us speed, accuracy, and flexibility to meet the most rigorous and specialized PCB requirements,” the company’s website said.

TJM Electronics, based in Warminster, Pennsylvania, offers PCB assembly in short and long runs, full production, cable assembly and complete box builds. In addition to defense and aerospace, it builds for the non-commodity consumer electronics markets.

“We strive to provide responsiveness and accuracy by utilizing modern process methodology, real-time communication, and employee empowerment and training to better help our customers succeed,” the company’s website said.

For its electro-mechanical assembly customers, TJM technicians source and install cables and sub-assembly components into a customized enclosure to meet a customer’s requirements. They will then test the assembly to confirm best performance.

“Our smart automated equipment allows us to manufacture simple to complex PCB assemblies up to 460mm wide and 1,200mm long in low to high volumes with precision, high reliability, and quick turnaround,” the website said. “We have a vast knowledge of PCB capabilities, including rigid, flex, rigid/flex, surface mount & thru-hole processing, and mixed technology.”

That includes the ability to assemble a single or double-sided board. TJM has the technology and expertise to deliver any electrical and mechanical assembly.

Its box builds include sourcing and installing cables, sub-assembly components, installing PCBAs, AC and DC power units, digital interfaces, audio/video, insulation displacement and other electrical systems and routing cable and wire harness assemblies into a single box enclosure.
