At our PCBA facility, production quality is supported by a carefully configured SMT line that combines automated board handling, precision solder paste printing, flexible placement, controlled reflow, and automated optical inspection(AOI). From the first PCB loaded onto the line to the final OK/NG s

What is AOI Automated Optical Inspection?AOI (Automated Optical Inspection) is a non-contact visual inspection equipment widely used in SMT assembly. It acts as a critical quality checkpoint for PCBA manufacturing. It catches visual defects at early production stages to avoid defective boards flowin

What is a stencil?A stencil is a thin metal foil with laser-cut openings. It is placed over the PCB pads, and solder paste is printed through those openings. The stencil acts like a mold: it controls exactly how much paste lands on each pad. If the paste does not release cleanly, defects follow—brid
