Electronics Assembly / SMT · Multi-Brand Device Data Acquisition & Correlation Analysis
For multi-brand, multi-protocol equipment on the SMT line, a protocol gateway connects printers, SPI, placement machines, reflow ovens and AOI data, while the G220 adds screen-level tuning and OCR verification — supporting SPC and yield improvement.
Core solution for this scenario

The SMT line is a tightly coupled process chain of "printer → pick-and-place machine → reflow oven → AOI", where a parameter drift at any single stage is amplified downstream. Solder-paste thickness from the printer, placement-coordinate accuracy from the pick-and-place machine, and the reflow oven temperature profile must be data-linked to locate the root cause of defects — collecting a single stage in isolation has limited value. This is precisely why SMT yield optimization must rely on "line-wide data acquisition + cross-device correlation" rather than single-machine monitoring.
I. Industry Pain Points
Typical challenges for Electronics Manufacturing / SMT Surface Mount in equipment O&M and data acquisition.
- SMT-line equipment brands are highly mixed (printers, SPI, placement machines, reflow ovens, AOI from different vendors) with disparate protocols, so data is naturally siloed and hard to correlate end-to-end.
- Key parameters such as reflow temperature profiles and placement offsets are scattered across equipment HMIs; manual aggregation is lagging and error-prone, so SPC is hard to truly implement.
- AOI defect results cannot be quickly correlated with upstream / downstream process parameters to locate root cause; quality traceability is difficult.
- Legacy equipment has no network port and exposes no protocol, becoming a blind spot in data acquisition.
II. Solution
Build a "screen layer + protocol layer" dual-source data closed loop with the AIXOT non-intrusive gateway combination.
- AIS-G160 Industrial Protocol Gateway uses its 500+ protocol library to unify access to printers, SPI, placement machines and reflow ovens, performing data cleaning and anomaly pre-screening at the edge, and reporting standard protocols to MES / SPC.
- APM-G220 Non-intrusive Smart Tuning Gateway non-intrusively takes over the IPC-controlled device screen for parameter review and OCR text records, bringing the “screen layer” judgement into the quality closed loop.
- Continuous variables — reflow temperature profile, placement coordinates, SPI solder-paste thickness — are correlated with AOI defect results on a timeline, supporting SPC and yield root-cause analysis.
- For legacy protocol-less devices, G220 + AIS-T100 Video OCR Data-Collection Gateway OCR provides fallback capture of key screen parameters, eliminating data blind spots.
III. Deployment Steps
An executable path from interface inventory to a standardised closed loop.
- Inventory each SMT-line equipment vendor / model and communication interface (Ethernet / RS485 / OPC UA)
- Configure the corresponding G160 protocol template and acquisition period; compute temperature / offset anomaly pre-screening at the edge
- The G220 takes over the AOI industrial PC, records a tuning script and adds OCR verification, bringing it into the quality closed loop
- Correlate device data on a timeline by board ID / batch; build an SPC dashboard and defect traceability chain
- Set threshold alarms for key processes; on anomaly, auto-correlate upstream / downstream parameters to locate root cause
IV. System Integration & Data Connectivity
Standardised connection points with MES / SCADA / PLC / quality systems.
- Connect to MES / SPC: device continuous variables reported via OPC UA / Modbus TCP
- Connect to the electronic batch record: board ID–parameter–defect correlation supports traceability
- Complement with AIS-T100 Video OCR Data-Collection Gateway OCR: fallback capture of protocol-less device screen parameters
V. Value & Quantified Metrics
Measurable benefits from the non-intrusive solution.
VI. Deployment Boundaries & Compliance Red Lines
Compliance & applicable boundaries
General electronics manufacturing in a non-sensitive industry may use the 4G public network for non-sensitive commissioning, but for customers involving core process parameters a private / intranet network is recommended. The G220 applies only to PC-controlled devices; pure controller protocol acquisition is handled by AIS-G160 Industrial Protocol Gateway.
VII. FAQ
High-frequency questions for the Electronics Manufacturing / SMT Surface Mount scenario.
What if different brands' equipment protocols are incompatible?
The G160 has a built-in 500+ industrial-protocol library covering mainstream printers, placement machines and reflow ovens; less common brands can be connected via a custom protocol / register mapping.
How to improve SMT yield?
G160 collects entire-line process parameters; reflow temperature profile, placement coordinates and SPI solder-paste thickness are correlated with defects on a timeline, supporting yield root-cause analysis via SPC dashboards.
How is the reflow temperature profile used for SPC?
The G160 continuously acquires oven temperature and belt speed, aligned on the board-ID timeline, and feeds the SPC dashboard for trend and breach analysis.
Can legacy devices without a network port be acquired?
Yes. Screen-class parameters are covered by G220 + AIS-T100 Video OCR Data-Collection Gateway OCR fallback; devices with a serial port are acquired by the G160 via RS485.
In the 'Electronics Manufacturing / SMT Surface Mount' scenario, which CNC, PLC and injection-molding brands can G160 connect to?
AIS-G160 ships a 500+ industrial-protocol driver library, verified for CNC systems from FANUC, Siemens, Mitsubishi, SYNTEC; PLCs from Siemens, Mitsubishi, OMRON, Delta, Inovance; and injection machines from Techmation, Keqiang, Mediatek, Chen Hsong. See the 'Device Compatibility' list on this page for specific models; some legacy devices require on-site confirmation of network/extension-module conditions.
