An online AOI inspection machine only pays back when it matches the line it sits in, and the T7 AI AOI inspection machine is configured around the four constraints that decide that fit: board size and thickness, single- or dual-track flow, 2D versus 3D defect classes, and whether the station runs after reflow or after wave soldering.
An online AOI inspection machine is the optical inspection station that checks component presence, position, polarity and solder joints while boards are still moving on the line conveyor. It normally sits directly after the reflow oven, catching placement and solder defects before any further value is added. On mixed-technology lines, a second AOI station after wave soldering inspects through-hole joints on the same conveyor path.
Work through these in order. Each answer narrows the configuration rather than the brand, so by the fourth question you should have a model name and a reason for it.
Published T7 data covers 0.3–6 mm board thickness, and the standard board format can be customized — the exact panel envelope is confirmed with sales during quotation. If your largest panel or your thinnest board falls outside the standard range, fix that number before you compare anything else.
Recommended T7 / T7D
Reason: the board envelope decides whether you are buying inside a standard range or configuring a custom format.
Single-track T7 or double-track T7D is selected based on production capacity. A single lane suits high-mix production where changeover matters more than raw throughput; a double-track machine suits lines running two products in parallel or where cycle time is the bottleneck.
Recommended T7 (single-track) or T7D (double-track)
Reason: the track choice in the T7 series is made on capacity, not on board size.
The T7 platform inspects in 2D as standard, with 3D detection available as an option. Pull the 3D lever when height-dependent features such as solder volume appear in your escape list; start from a native 3D platform instead when three-dimensional inspection is the main requirement rather than an occasional check.
Recommended T7 with 3D option, or T9D
Reason: 3D as an option covers occasional height checks; 3D as a platform covers a 3D-first inspection strategy.
The T7 series is stated as applicable to post-wave soldering scenarios as well as the standard post-reflow position, so one platform can cover a second inspection point after the wave solder station on mixed-technology boards.
Recommended T7 / T7D
Reason: a post-wave station changes the defect mix you are hunting, not necessarily the machine you need.
Side-by-side comparison of the configurations discussed above. Published figures come from the T7 product page; anything marked “confirm with sales” is configuration-dependent and is quoted against your board data.

The T7 is a digital AI AOI optical inspection platform for online SMT inspection. Here is the configuration detail that usually decides the purchase, followed by the three benefits buyers ask about first.
AI programming is stated at about five minutes with no CAD file required — one good-quality board is enough to teach the model. In high-mix production that removes the offline programming session that normally sits between a new board arriving and its first inspection.
The self-learning AI adapts as it operates, and the page states that false alarms can fall by up to 80% after two to three operating cycles. Fewer false calls means fewer boards pulled off the line for manual re-check — which is where AOI usually consumes operator time.
Inspection runs locally, keeping board data inside the factory, and operators are stated to reach working speed in around 30 minutes. Automated calibration and an intuitive interface support that ramp, and the platform is described as overcoming the colour and character interference that trips up conventional AOI.
Four configuration levers carry most of the cost difference between quotations, and one operating metric carries most of the return.
Single-track T7 versus double-track T7D is the largest configuration decision on the table. The track is chosen from production capacity, so it should be justified by throughput or takt time — not by future-proofing alone.
2D inspection is standard on the T7 platform and 3D detection is an option. Pay for it when height-dependent defects sit in your escape list; if they dominate the list, start from a 3D platform such as the T9D instead of adding 3D to a 2D machine.
The stated 5 μm resolution and 100+ mm/s inspection speed already cover 0201 components as standard, with 01005 available as an option. Step up only when your smallest component or your takt time genuinely demands it.
Barcode scanning, MES connection and 3D detection are optional extras. Each one adds cost, so decide at quotation which of them your traceability requirement actually needs rather than carrying all three by default.
Every false alarm costs a manual re-check. The self-learning model is stated to reduce false alarms by up to 80% after two to three operating cycles, and operators are stated to be productive in about 30 minutes. Multiply those two numbers against your shift pattern and your re-check time to size the benefit before you compare quotations on price alone.
Send your board envelope — largest and smallest panel plus the 0.3–6 mm thickness range — your lane count, the reflow and wave station positions, and the defect classes you need to catch. Sales returns a configuration and the latest quote. Custom board formats, power and air pressure conditions, packaging and post-supply services are confirmed directly during quotation, and OEM/ODM, bulk-order and distributor enquiries are handled the same way.

View productthey are two configurations of the same ai aoi series. t7 is the single-track machine and t7d is the double-track machine, and the product page states that the choice is made based on production capacity.
the t7 platform inspects in 2d as standard, with 3d detection available as an option. choose the 3d option when height-dependent defects are part of your escape list; start from a native 3d platform such as the t9d dual-track machine when three-dimensional inspection is the main requirement rather than an occasional check.
yes. the t7 series is stated as applicable to post-wave soldering scenarios, so it can serve as the inspection point after the wave solder station on mixed-technology lines in addition to the standard post-reflow position.
board thickness is stated as 0.3–6 mm. the standard board format can be customized, and the exact panel envelope should be confirmed with sales during quotation so the configuration matches your largest and smallest production panels.
ai programming is stated at about five minutes with no cad file required — one good-quality board is enough to teach the model. operators can be brought up to working speed in around 30 minutes.
workshop space is stated at 1 × 1.5 × 1.6 m with a 1000 kg load-bearing requirement, and power is ac 100–240v, 50/60hz. power and air pressure conditions are confirmed with sales before installation.
