STC Electronics recently installed equipment for a new circuit-assembly line, enabling the company to better meet the continuing transition to surface-mount printed circuit boards. The line is housed in a new room with positive-pressure hepa air filtering.
The mid-volume assembly equipment includes a stencil printer, pick-and-place machine, lead-free reflow oven, and low-discharge deflux system.
Due to the size and weight advantages, Surface-Mount Technology (SMT) has become the preferred method for assembling small PCBs with high connection density. Not surprisingly, the demand for surface-mount assembly has increased in proportion to the number of small devices in electronics markets. In fact, about 90 percent of new PCB assemblies manufactured by STC Electronics are made using surface-mount placement. The new equipment allows STC to more effectively manufacture these types of small components.
