1. What is a Traffic Boards OEM Multi-layer PCBA?

A Traffic Boards OEM Multi-layer PCBA refers to a multi-layer PCB assembly solution specifically designed for use in traffic management equipment, with design, manufacturing, assembly, and testing services provided by OEM/ODM manufacturers.

Typical applications include:

Intelligent Traffic Signal Controllers
LED Traffic Signs
Highway VMS (Variable Message Sign) Display Systems
Intelligent Parking Management Equipment
AI Traffic Camera Systems
Vehicle-to-Everything (V2X) Communication Devices
Radar Speed Measurement and Traffic Monitoring Systems
Smart City Traffic Control Terminals

2. Key Features of Traffic Boards OEM Multi-layer PCBA

High-Reliability Design

Traffic PCBAs typically incorporate:
Automotive-grade components
Industrial-grade PCB materials
Conformal coating
High-reliability soldering processes
AOI + X-Ray inspection
For critical traffic equipment, the requirement for the PPM defect rate is extremely low. Consequently, multi-layer PCB inspection and quality control have become a key focus within the industry.

Multi-layer High-Speed Signal Architecture

This necessitates that the PCB possess:
A higher layer count
Enhanced signal integrity
Impedance control
High-speed differential routing
EMI suppression capabilities
HDI (High-Density Interconnect) and micro-via/buried-via technologies are being widely adopted.

High Power and Thermal Dissipation Capabilities

Therefore, the following are frequently employed:

Thick-copper PCBs
Metal-core PCBs
Multi-layer thermal management designs
Thermal simulation optimization
Thermally conductive materials

Intelligence and Networking Capabilities

As a result, Traffic Boards have begun to integrate:

MCUs/MPUs
ARM platforms
Linux operating systems
AI Edge Computing
Wireless communication modules

5.BQC Core Value

Be Honest: Don't cheat customers, Don't cheat colleagues, Don't cheat suppliers
Share: share profit with all employees, and welcome excellent management staff to hold share of the company.
Feedback: Take carbon peaking and carbon neutrality as the goal, powered by innovation and based on energy storage to feed back the country and society.
Customer-first: Opposing taking the boss, R&D, and manufacturing as the center. Taking customers representative as the center internally, and taking customers as the center externally.

6.RFQ

Q1:What is the point of having multiple layers on the PCB board?

A1:PCBs have multiple layers primarily to increase circuit density, improve signal integrity, and reduce overall size and weight. By stacking conductive copper layers separated by insulating substrates, designers can route complex circuitry, create dedicated power and ground planes, and significantly reduce electromagnetic interference (EMI) compared to single-layer boards.

Q2: what's your test capacity?

A2:We conduct 100% AOI test, visual inspection and function test; we also have ICT tester.
