Precision in the Sub-Millimeter World

Driven by the demand for smaller, lighter, and more powerful devices (wearables, medical sensors, 5G modules), PCBA manufacturing is rapidly moving towards micro-miniaturization. This trend means adopting tiny, passive components like the 0201 (0.6mm*0.3mm) and the even smaller 01005 (0.4mm*0.2mm).

These components are barely visible to the naked eye. Handling and placing them successfully is the ultimate test of a PCBA supplier’s precision equipment, process control, and engineering expertise. This article details the three critical factors necessary to achieve high-yield Surface Mount Technology (SMT) for ultra-fine-pitch components.
