Full service Electronic Contract Manufacturing and Test

TJM Electronics Associates with locations in Arizona and Pennsylvania, specializes in contract manufacturing and custom automation, testing, and fixturing equipment. Our design team is a “complete package”, offering customer’s software design, hardware design, mechanical design, functional test system design and systems integration. With our broad range of expertise there is no job we can not do. From the simplest test fixture to the fully automated system, we can do it all. We have designed for various market segments such as Telecommunications, Military, Automotive and Semiconductor.

TJM Electronics East employs over 50 dedicated engineering, assembly, machine operator and quality control personnel. TJM East provides engineering and purchasing along with unsurpassed service and quality in electronic packaging handling quantities from as low as 1 to more than 5,000 assemblies per month. TJM provides engineering prototypes and low to medium volume assembly of many high visibility products.

TJM Electronics West is a family owned and operated company which introduced its Arizona facility in 1993 in support of a high tech semiconductor corporation and its development of ISA and MCI Bus Digital video cards. These high exposure digital video cards showcased the company's RISC and Pixel Processors. Services consisted of fast turn prototype assembly, modifications and diagnostics on both the IBM PC and PS2 platforms. By 1994 TJM Electronics West started providing electronics assembly services to many other high tech electronics companies in the Phoenix area. In June of 2000, TJM expanded into its third and current location in Tempe.

TJM Electronics Associates is a highly technical state of the art electronic contract manufacturer, diversified in its service support of over 70 customers. We are a family owned and operated business whose primary goal and focus has always been to insure the success of our customers. We have grown to two facilities and over 80 people specializing in the field of robotic surface-mount electronic assembly. While working in engineering support at the David Sarnoff Research Center, we became involved in the development of this process and the component standardization for building today’s printed circuit boards. TJM was a founder of the Surface-Mount Technology Association promoting the equipment and processes used to build the sub assemblies used in all electronic instruments.

TJM Electronics Associates, by the nature of the new processes it utilizes, has always attracted potential customers. An approach was taken early on to project a match between the customer requirements and our own capabilities. Since the beginning we have focused on serving customers who needed support in doing development prototypes and pilot runs on new products & processes we could grow with. Our advanced technology labs work in support of many of today’s largest semi-conductor manufacturer profiling processes for new packages.

TJM Electronics Associates worked with AT&T engineers over fifteen years ago is early development of BGA packages. Today we’re involved with OnSemi and Motorola in the process requirement for the new QFN packages. Some assemblies we build for Defense Systems have over 4000 components with 36 BGA’s mounted on both sides.

Besides advance reflow profiling and solder stencil designs, TJM Electronics Associates is equipped with Ionic contamination testers, and X-Ray inspection. Our sixteen pick/place machines not only puts us in position for fast turn short runs (2 to 3 days), but also gives us the depth to support runs in the tens of thousands per month.
