Design And Manufacturing Of Printed Circuit Boards

SEA Company provides services in designing and manufacturing of printed circuit boards (PCB).

 

Our designers develop PCB routing in accordance with client’s requirements and specifications. We design single-layer, double-layer and multilayer PCBs (up to 20 layers) with dead or hidden vias; metal core PCBs; flexible and flexibly-rigid PCBs; radio frequencies and super-high frequencies PCBs, etc.

 

Our staff develop PCBs of any complexity as promptly as practicable. One should e-mail us technical specification to start the ball rolling. After approval for details we start up PCB development in strict accordance with the specifications and SOW.
