Pcb Fab

SI Electronics provides printed circuit board manufacturing services in addition to PCB assembly with superior quality and a cost-effective price. We are capable of meeting the ever-increasing demands of customers, from fabricating a single board, to a small quantity of prototypes, to a high-volume production requirement by using all types of materials and modern technologies. We are capable of manufacturing single, double-sided, multi-layer and flex PCBs to the customer's specifications. The following data is a detailed description of SI Electronics's PCB manufacturing capabilities:
