Mechanical Assembly

Mechanical assembly plant and skillful workers are the basic requirements for a printed circuit board EMS manufacturer. Mechanical assembly is a vital requirement after system integration assembly. Mechanical assembly involves riveting, drilling screw holes, tightening nuts and bolts, washers and mechanical locks to assemble core functional components inside final housing. 

Assembling simple products with no sub-components are far efficient as compared to assembling products with more than two sub-components. In theory, higher the sub-components, the more labor-hours are required for assembly process. While some EMS PCB manufacturers are unable to provide high quality mechanical assembly services, FS tech has expertise in this field also.
