Should I choose a GigE camera or USB camera solution for wafer inspection?

It depends on deployment and budget: choose GigE when transmission distance is long, complex networking is required, or jumbo frame / RDMA high bandwidth is needed; choose USB when workstations are concentrated, camera count is high, and lowest total cost with plug-and-play is preferred. Both deliver frame-loss-free inspection.

What practical value do jumbo frames and RDMA bring to wafer inspection?

Jumbo frames enlarge per-frame payload to cut frame processing overhead, raising image throughput at the same bandwidth. RDMA lets image data bypass the CPU and land directly in memory, lowering latency and CPU load while supporting concurrent multi-camera capture. Together they serve the hard requirement of zero frame loss. LR-LINK RDMA frame grabbers are currently in development.

How do I balance 2.5G, 5G and 10G bandwidth against cost?

First calculate total camera throughput (resolution x frame rate x bit depth) and plan for 70% of theoretical bandwidth as headroom: a single camera at gigabit rates fits 1G/2.5G; mainstream 5-megapixel multi-camera setups choose 5G; high-resolution, high-frame-rate multi-camera concurrency chooses 10G.

Why use fiber for lithography data transfer?

Mask layout data is huge and transmission spans workshop or even cross-plant distances. Fiber preserves signal integrity and resists electromagnetic interference far better than copper over long runs. Paired with a 2x100G fiber NIC and RDMA, it meets high-rate, low-latency, high-reliability requirements.

How should I understand 'In Production' vs 'In Development' in the selection table?

In Production products can be ordered normally. In Development products follow official release announcements - register your need via the form below and we will notify you first when released. For end-of-life products, please consult us for replacement options.

How do I scale a multi-camera setup with multi-port NICs?

Prefer multi-port frame grabber cards: each port carries independent bandwidth with no contention. Choose port count by summing camera bandwidth needs (e.g. 8-port 5G, 4-port 10G); add more cards when one card is not enough.

The vision stations across the packaging line

Wafer dicing needs alignment vision to cut along scribe lines. Die attach uses vision to place chips with micron accuracy. Wire bonding inspects each bond for broken, sagging or bridged wires. Final test scans for chip contamination, scratches and edge chipping. Every station has at least one camera, most have several — and all of them need reliable, low-cost image acquisition.

Why gigabit multi-port fits packaging

Packaging stations typically run 1-megapixel to 5-megapixel cameras at moderate frame rates — comfortably within gigabit bandwidth per port. Multi-port cards let one NIC serve several cameras or several stations from a single slot, expanding I/O without adding hosts. Simple cabling and fewer components keep the packaging line easy to maintain and quick to deploy.

Reliability in an aggressive environment

Packaging floors are full of vibration, heat and EMC noise from molding presses and test handlers. NICs for this environment need stable, well-tested controllers, robust PCB design and consistent performance under sustained load. LR-LINK cards in this line use production-proven controllers (Intel, Realtek, AQC) with jumbo frame support and are validated for 24/7 operation.

Rate ladder: 1G / 2.5G / 5G

Most packaging vision fits 1G; stations with higher-resolution or faster cameras step up to 2.5G (PoE+ frame grabbers) or 5G. The ladder keeps bandwidth and cost balanced: buy only what each station needs, and standardize cabling and software across the line.
