PCBA Assembly Process
1. SMT Assembly Process
‑ Fully‑automatic solder paste printing with SPI solder paste inspection;
‑ High‑speed mounter for BGA main controller, Flash memory IC, QFN chips, SMD resistors & capacitors and MOSFETs;
‑ 10‑zone reflow oven with segmented temperature control to avoid thermal deformation of high‑power boards;
‑ Automatic AOI optical inspection to detect cold solder, insufficient solder, component offset and tombstoning defects.
2. DIP Through‑hole Insertion Process
‑ Manual & automatic insertion for electrolytic capacitors, common‑mode toroidal inductors, high‑frequency transformers, fuses, varistors and connectors;
‑ Wave soldering for through‑hole components.
3. Post‑processing Procedures
‑ Manual rework soldering, component shaping and board cleaning;
‑ High‑voltage insulation test, power‑on functional test and burn‑in aging test;
‑ Full visual inspection, connector check and full‑channel function verification;
‑ ESD‑protected finished‑product packaging.
> Assembly Features: Hybrid process combining high‑density SMT chips and high‑power DIP components. Layout separates high‑voltage and low‑voltage circuits with isolation design to meet safety and EMC electromagnetic‑compatibility requirements.
Product Advantages
1. Multi‑mode Power Compatibility: Supports POE, AC24V and DC36V power supplies. Adapts to diverse on‑site cabling conditions for security projects and reduces power‑system renovation costs.
2. Outdoor Lightning & Surge Resistance: Two‑stage lightning‑protection circuit built with varistors and gas discharge tubes, paired with common‑mode inductors for EMI filtering. Effectively withstands lightning strike, static electricity and grid surges to enhance long‑term reliability in field deployment.
3. Integrated Binocular AI Audio‑video Solution: Dual‑channel image acquisition powered by NT98539 AI chip for intelligent analytics such as perimeter intrusion detection and line‑crossing detection. Two‑way audio intercom is integrated for monitoring scenarios in parks, construction sites and road surveillance.
4. Rich Peripheral Driver Integration: Onboard drivers for lens low‑temperature anti‑fog heating and IR night‑vision supplement light; ALM dry‑contact alarm output for external audible‑visual alarm devices; CVBS analog video port facilitates production debugging.
5. Dual‑storage Recording Solution: On‑board NAND Flash plus expandable TF‑card slot for dual backup of local video and snapshots. Video files can still be saved even under network outage.
6. Mature Process for Complex Components: Precise BGA mounting, mechanical locking & reinforcement for high‑power POE transformers and large‑size common‑mode inductors, plus heat‑sink assembly. Strictly controls typical defects including BGA cold solder, lifted through‑hole parts and PCB warpage to satisfy anti‑vibration requirements of outdoor equipment.
Application Fields
Outdoor Binocular AI Network Bullet Cameras, Binocular PTZ Dome Cameras, Park Surveillance Cameras, Intelligent Construction‑site Monitoring Equipment, Substation Monitoring, Road‑side Security IPC, Industrial On‑site Audio‑video Acquisition Devices.
