Comprehensive Automation Solutions for the Electronics and Electrical Industry
Applicable to enterprises in the following sectors: consumer electronics, home appliance electronic control, PCBs, SMT, connectors, wire harnesses, power supplies, motors, sensors, relays, and photovoltaic/energy storage electrical components.
The core focuses on: high-precision manufacturing, high-reliability inspection, end-to-end traceability, flexible mixed-line production, and dust-free, electrostatic-safe operations.
 

I. Core Pain Points of the Industry
● Miniaturization and high precision of products make manual assembly challenging.
● Numerous processes, including SMT, component insertion, soldering, dispensing, fastening, and testing, with extremely stringent quality requirements.
● Multiple product varieties, small batch sizes, and frequent changeovers make production scheduling complex.
● Electrostatic discharge, dust, and temperature/humidity have a significant impact on yield.
● Critical processes must be fully traceable (materials, equipment, parameters, personnel, and test data).
● Manual inspection is inefficient, inconsistent, and carries a high risk of missed defects.
 

II. Overall Solution Architecture
1. Top-Level Design: Digitalized Electrical and Electronic Workshop
● Raw Material Storage → SMT Workshop → Component Insertion and Soldering → Coating/Encapsulation → Precision Assembly → Functional Testing → Visual Inspection → Aging → Packaging and Warehousing
2. Core Software System
● ERP: Orders, Procurement, Costs, Delivery
● MES (Core): Work Orders, Traceability, Error-proofing, SPC, OEE, Electronic Kanban, ESD Monitoring
● WMS: First-In, First-Out material management, batch management, and sensitive component control
● QMS: IQC/IPQC/FQC/OQC, 8D Reports, Defect Analysis

● FCT functional testing: voltage, current, power, communication, and logic
● Aging tests: automated monitoring of high- and low-temperature testing, energized aging, and cyclic aging
● Safety compliance testing: withstand voltage, insulation, and grounding resistance
● Automatic upload of test data; automatic diversion of non-conforming results
6. Full Coverage of Visual Inspection
● AOI: solder joints, appearance, missing parts, and incorrect parts
● Visual positioning: High-precision assembly guidance
● Appearance defects: scratches, dirt, deformation, color variation
● Character recognition: model number, batch number, barcode, and QR code reading
7. Cleanroom and ESD Electrostatic Control

● Material-loading error-proofing: scan-based matching of materials, workstations, and material-station tables
● JIT material delivery to reduce line-side inventory
 

V. Quality Traceability System (Mandatory Requirement for the Electronics Industry)
● Each PCB / each product is assigned a unique serial number for traceability:
● Material batches (ICs, capacitors, PCBs, wires, etc.)
● Equipment parameters (pick-and-place machine, reflow oven temperature, dispensing, and screw-locking torque)
● Test data (ICT/FCT/ Safety Compliance/Aging)
● Operator, time, process, and environmental data
● Compliance: IATF 16949, ISO 9001, and regulatory requirements for medical devices and automotive electronics
 

VI. Typical End-to-End Process Flow (Using a Controller/Power Supply as an Example)
