Dual Magazine PCB Unloader for Continuous End-of-Line Collection
Two magazines work in parallel so one can keep collecting boards while the other is changed out. This avoids the small but costly line interruptions common with single-magazine unloaders.
| Model | SLD-3 |
| Magazine Configuration | Dual parallel magazines |
| PCB Size | 50 × 50 – 460 × 460 mm |
| Magazine Swap | One side active while the other side is replaced |
| Interface | SMEMA compatible |

Who This Unloader Fits Best
High-Volume SMT Lines
Best where even brief magazine-swap stoppages create measurable throughput loss over long production runs.
Continuous Shift Production
Dual magazines reduce how often operators must intervene and help keep collection from becoming the line bottleneck.
Compared with Single-Magazine Unloaders
Choose this model when collection uptime matters more than the lower cost and simpler structure of inline or side-exit unloaders.
Compared with OK/NG Unloader
This model increases collection capacity; OK/NG models separate boards by quality signal instead of maximizing uninterrupted capacity.
