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.

When USB beats GigE for wafer inspection

GigE is the right choice for long transmission distances, complex networking and maximum bandwidth. But on a dense inspection floor, where cameras sit within a few meters of the host, USB frame grabbers remove most of the network complexity: no switch configuration, no IP planning, no jumbo-frame setup across infrastructure. Plug the card in, connect the cameras, and capture.

Independent bandwidth: cameras never fight

A shared bus is the classic failure mode of cheap multi-camera capture. LR-LINK USB frame grabber cards give each port its own dedicated bandwidth, so one camera bursting at full rate cannot starve its neighbors. Multi-camera concurrent capture runs without dropouts — the same frame-loss-free guarantee as our GigE line, in a simpler form factor.

Cost model that favors the operation

USB cameras and accessories are widely available at controlled cost, and the card itself needs no managed switch, no trained network engineer on site, and no complex network configuration. For concentrated, multi-camera workstations, total cost of ownership is hard to beat.

Tier roadmap: 5G, 10G, 20G

The USB frame grabber line is rolling out in tiers: 5G cards in dual-channel 4-port and quad-channel 8-port variants, 10G dual-channel 4-port, and 20G in development. As products launch they will appear on the semiconductor solutions page — register your requirement via the form and we will notify you at release.
