Custom PCB Assembly Solutions

TJM Electronics is a leading PCB assembly manufacturer in the northeastern United States, offering turnkey custom printed circuit board assembly services.

Using both automated and manual techniques for placing PCB components, we are able to meet the most rigorous and specialized design requirements for industries such as Aerospace and Defense, Medical, Industrial, LED lighting, and Non-commodity consumer electronic products. 

Our PCBA’s are known for advanced functionality and long-lasting reliability, which is crucial for electronic products that perform in extreme or critical conditions. State-of-the-art surface mount technology and thru-hole soldering equipment give us the speed, accuracy, and flexibility to process virtually any printed circuit assembly project. Whether high density or low-to-high volume, we have the ability to deliver quick-turn mass production assemblies.

TJM Electronics can assemble printed circuit board assemblies up to 1200mm (47.24″) in length for short or long runs. Our larger boards are typically used for LED lighting applications manufactured through our lighting brand, TemitroniK.

High-Quality Manufacturing and PCB Assembly

At our facility in Warminster, PA, we run smart, automated electronic assembly lines that include pick and place machines with mounting speeds to 45,300 cph and fine pitch down to 0.3mm.

We also have various reflow ovens, a selective soldering system, 3D paste inspection machines, and 3D automatic optical and x-ray inspection systems. In addition, we provide environmentally safe board cleaning with de-ionized water recycling, ROSE testing, and humidity-controlled storage for moisture-sensitive devices.

Understanding the challenging and demanding needs specific to the Aerospace and Defense industries, we cater our PCBA efforts to withstand harsh conditions imposed by extreme temperatures, moisture, shock/vibration, mechanical abuse, or any other hazardous conditions that can defect the finalized product.

TJM services customers in various industries. Due to our growth in the Aerospace and Defense industry, we have decided to pursue AS9100D as our primary Quality Management System to create standard operating procedures across all business segments. This allows us to enhance the quality of our product while increasing efficiencies and alleviating undue price increases to our customers.

Whether your technology includes Surface Mount (SMT), Through-hole, or a mixed technology for single or double-sided boards in small quantities, prototypes, or large production runs, TJM has the ability to provide for all of your contract electronics manufacturing needs.
