Production Process Flow
Overall Process: PCB incoming inspection → Solder paste printing → SMT mounting → Reflow soldering → AOI optical inspection → Plug-in component welding → Board cleaning → Program burning → Functional testing → Aging test → Final inspection → Packaging and delivery
IQC Incoming Inspection
Check the appearance, silk screen, holes and circuits of PCBs to ensure no short circuit or open circuit. Verify that the model, specification, package and batch of electronic components are consistent with BOM standards. Reject all oxidized, damaged, wrong and mixed materials strictly.
SMT Mounting Process
Adopt fully automatic solder paste printing with stencil openings matching conventional 0603 and 0805 packages. Ensure precise component mounting without offset, tombstoning or cold solder joints. The reflow soldering temperature curve is set in accordance with civil control board standards.
Through-Hole Welding Process
Complete manual welding for plug-in components such as digital tubes, function keys, charging ports, buzzers and sensor sockets. Ensure full and firm solder joints without cold solder, false solder or excessive tin. Trim component pins neatly without burrs and residues.
Board Cleaning Process
Clean all flux residues on the board surface after welding. Ensure the board is free from yellowing, oil stains and residual flux to prevent moisture-induced leakage, circuit corrosion and subsequent functional failures.
Program Burning Process
Burn unified mass production programs and calibrate standard alcohol detection parameters for each board. Mark production batches after burning to prevent unprogrammed, incorrect or outdated program boards from flowing out of the factory.
Functional Testing Process
Conduct full-functional inspection for every single board, including power-on self-test, screen display, key triggering, charging function, low battery reminder, alcohol concentration identification and multi-level audio-visual alarm. Isolate and mark defective products independently.
Aging Test Process
Perform power-on aging test for more than 2 hours at room temperature. Simulate repeated power on/off, standby and detection working conditions to screen out unqualified boards with parameter drift and abnormal operation.
Quality Inspection Standards
Appearance Standard
- Board surface is clean and tidy with clear silk screen printing
- All solder joints are uniform and full without bridging, cold solder, missing solder or solder explosion
- No skewed, damaged or reversely installed components
- Board is free from scratches, stains and copper foil peeling
Electrical Performance Standard
- No circuit short circuit or open circuit
- Normal charging and power-off protection functions
- Sensitive key response and clear screen display
- Stable detection data and accurate graded alarm without garbled characters, crash or abnormal restart
Stability Standard
- No abnormal heat generation or parameter drift during continuous power-on test
- All functions remain normal after simple high and low temperature tests
- Meeting the long-term service requirements of civil products
Defect Judgment and Processing Rules
- Severe defects (failure to power on, no display, key failure, charging failure): Rework or scrapping required
- Functional defects (detection data drift, alarm disorder, occasional crash): Isolated for rework
- Slight appearance defects without functional impact: Downgraded delivery or delivered after customer negotiation
- All defective products shall be stored in separate areas with recorded batch information and defect causes to realize quality traceability
Packaging and Delivery Standards
- Each single board is independently packed with an anti-static bag
- All products are placed in anti-static cartons with partition boards
- Mark product model, quantity, batch number and production date on outer cartons
- Provide quality inspection reports and delivery lists with goods to support batch inspection
Factory Production Capacity
We support fast sampling, small-batch trial production and stable mass production. The whole industrial chain is independently completed in-house, including PCB design, component procurement, SMT mounting, program development and aging testing.
Customized services for board size, functions, parameters and program interfaces are available, providing one-stop PCBA processing and customization solutions for breathalyzers.
