No-Clean Solder Paste

Qualitek International's 690 Delta Elite no-clean solder paste features a tack time of more than 50 hours, resulting in usable materials for several days. High tack force allows for high speed component placement without misalignment or tombstoning defects. Longer tack time and stencil life reduces waste of material by opening the process window to accommodate lags in production and batch operations.
