KART provides efficient one-stop circuit board prototype services to clients who are looking for a total "all under one roof" solution for their outsourcing requirements. We see ourselves as partner and act as an extension to your own manufacturing facility, working closely with your staff to help you save the cost and time.

Our high-tech assembly facility offers both surface mount (SMT) and conventional (through-hole) PCB Assembly methods, both of which can be combined to create mixed-technology PCB assemblies.

We have specialized in providing contract electronics manufacturing services to companies operating in a wide variety of market leading, high technology business sectors including Oil & Gas, Medical, Audio, Automotive, and LED, security, GPS. 

With Partial Turn-Key, you provide the blank PCB’s and we assemble according to your requirements. You have the option of providing some or all of the components, and KART dedicated Procurement team will assist with any remaining parts.
