Q: What placement-machine accuracy does this LED require?
A: This product uses a 3227 package (3.2×2.7mm) with relatively large pads. Ordinary high-speed placement machines meet its needs, with no special equipment accuracy requirements. Its multiple-pad structure requires each stencil aperture to align with its corresponding pad. Supports lead-free reflow soldering (peak ≤260℃/≤3s).
