Electronic Assembly

Combining automated SMT, BGA and PTH technologies for single or mixed technology requirements. In production, GWT will manufacture monthly quantities ranging from a few units to high volume.


A cost effective solution to the complex realities of manufacturing management. Supplying materials, technical support, manufacturing and assuming complete responsibility for attrition and product workmanship. We typically supply the PCB, components, and tooled parts.


Offering collective purchasing strength and convenience to improve customer costs and efficiency. Employing statistical process control techniques to achieve better performance from our vendors in terms of quality and on-time delivery.


Assembly services using customer supplied materials. All materials provided are carefully audited to assure agreement with packing documentation and the Bill of Material. Acknowledgements are promptly issued to confirm any material shortages and discrepancies.


Start to finish product manufacturing. Strategic product planning at every stage of production to assure consistent processes, sequencing and complete product control.

Prototype and NPI Production, PCB / PCBA

Production-ready at any stage. Our flexible and highly efficient staff is ready to meet your specific prototype needs in a timely manner.

Product Design, Development & Documentation

Providing expertise in design and value manufacturing while preparing efficient documentation for product manufacturing. GWT confidently recommends Mark Desantis of Valencia Circuitworks as a reliable design engineer option if you are looking to complete your design or need any related help in that area.

Engineering Support, Component / Manufacturability / Test

Utilizing engineering support techniques to assist in areas like component engineering and identification, manufacturability analysis, and value engineering. Offering solutions that enhance manufacturing and test yields, and related product reliability.
