A Printed Circuit Board (PCB) Interconnection System refers to the complete network of electrical pathways and structural interfaces that enable signals, power, and control data to flow between electronic components within and across one or more PCB boards. It includes copper traces, vias, pads, connectors, backplanes, cables, and inter-board communication interfaces that collectively ensure reliable electrical continuity. In modern electronic equipment—such as industrial controllers, elevator systems, medical devices, and power modules—the interconnection system determines signal integrity, system stability, and long-term reliability.

Взаимосвязь между системой межсоединений печатной платы и услугой обратного проектирования печатных плат является как прямой, так и технической. При выполнении обратного проектирования печатных плат наши инженеры должны восстановить не только принципиальную схему, но и полную топологию межсоединений. Это включает в себя извлечение списка соединений, анализ трассировки медных проводников, определение параметров структуры слоев и сопоставление выводов разъемов. Точное восстановление системы межсоединений гарантирует, что восстановленные файлы Gerber и файлы CAD точно воспроизводят исходное электрическое поведение. Без точного восстановления межсоединений дублированная печатная плата может выглядеть идентично, но функционально выйти из строя из-за неправильной трассировки сигналов или путей распределения питания. Кроме того, понимание системы межсоединений печатной платы позволяет нашей услуге обратного проектирования выйти за рамки простого дублирования. В процессе восстановления мы можем анализировать пропускную способность по току, временные характеристики сигналов, риски электромагнитных помех и тепловые пути. Это позволяет контролируемо модифицировать, оптимизировать или восстанавливать печатную плату, сохраняя при этом совместимость системы. Для устаревших или недокументированных плат восстановление системы межсоединений часто является наиболее важным шагом для достижения надежного воспроизведения.
At the single-board level, the PCB interconnection system consists of trace routing, multilayer stack-up configuration, power and ground planes, impedance-controlled lines, and via structures. These elements form the internal electrical architecture of the board. Proper interconnection design ensures minimal signal loss, controlled impedance for high-speed circuits, stable power distribution, and effective electromagnetic compatibility (EMC) performance. Poor interconnection layout can result in noise coupling, voltage drops, overheating, or intermittent system faults. Therefore, the PCB interconnection system is not merely wiring—it is a carefully engineered electrical infrastructure.
Printed Circuit Board Interconnection System refers to the entire electrical path from the transmitter to the receiver on the PCB board, including chip package, connector, transmission line, via, connector, etc. The signal integrity problems caused by the interconnection effect are:

PCB 상호 연결 시스템과 PCB 역설계 서비스는 직접적이고 기술적인 관계를 가지고 있습니다. PCB 역설계를 수행할 때, 당사 엔지니어는 회로도뿐만 아니라 전체 상호 연결 토폴로지까지 재구성해야 합니다. 여기에는 넷리스트 추출, 구리 배선 분석, 레이어 스택업 파라미터 식별, 커넥터 핀 배치 매핑 등이 포함됩니다. 상호 연결 시스템을 정확하게 복구하면 재생성된 Gerber 파일과 CAD 파일이 원래의 전기적 동작을 충실하게 재현할 수 있습니다. 상호 연결 시스템을 정확하게 재구성하지 않으면 복제된 PCB는 겉보기에는 동일해 보일지라도 신호 배선이나 전력 분배 경로가 잘못되어 기능적으로 제대로 작동하지 않을 수 있습니다. 또한, PCB 상호 연결 시스템에 대한 이해는 당사의 역설계 서비스를 단순한 복제 이상의 단계로 끌어올립니다. 복구 과정에서 전류 용량, 신호 타이밍, EMI 위험, 열 경로 등을 분석할 수 있습니다. 이를 통해 시스템 호환성을 유지하면서 PCB를 제어적으로 수정, 최적화 또는 재제조할 수 있습니다. 단종되었거나 관련 문서가 없는 보드의 경우, 상호 연결 시스템을 복원하는 것이 안정적인 복제를 달성하는 데 가장 중요한 단계인 경우가 많습니다.
1, The delay signal is transmitted at a limited speed on the printed circuit board pattern track, and it takes a certain time for the signal to propagate from the transmitting end to the receiving end, which is the transmission line delay. When the transmission line is too long, the signal delay will affect the system timing. In high-speed digital systems, the delay of the transmission line depends on the dielectric constant of the dielectric material, the length of the transmission line, and the geometry of the cross section of the transmission line.
2, When the characteristic impedance of the Printed Circuit Board Interconnection System does not match the termination impedance of the source or the load, the signal will be reflected back along the transmission line at the transmitting end and the receiving end, causing distortion of the waveform and even overshoot and undershoot. Multiple reflections of the signal back and forth will produce ringing. The geometry of the wiring, incorrect line termination, discontinuity of the power plane, etc. will cause reflections.
3, The problem caused by the discontinuity of the interconnect is essentially a reflection. The discontinuity of the interconnect is the discontinuity of the impedance. When the signal is transmitted to it, it will cause reflection. In actual PCB board layout, discontinuities such as vias, cross-segments, corners, etc. are often encountered in Printed Circuit Board Interconnection.

A relação entre o sistema de interconexão de PCBs e o serviço de engenharia reversa de PCBs é direta e técnica. Ao realizar a engenharia reversa de PCBs, nossos engenheiros devem reconstruir não apenas o diagrama esquemático, mas também a topologia completa de interconexão. Isso inclui extrair a netlist, analisar o roteamento de cobre, identificar os parâmetros de empilhamento de camadas e mapear a pinagem dos conectores. A recuperação precisa do sistema de interconexão garante que os arquivos Gerber e CAD regenerados reproduzam fielmente o comportamento elétrico original. Sem uma reconstrução precisa da interconexão, uma PCB duplicada pode parecer idêntica, mas apresentar falhas funcionais devido ao roteamento incorreto de sinais ou caminhos de distribuição de energia. Além disso, a compreensão do sistema de interconexão da PCB permite que nosso serviço de engenharia reversa vá além da simples duplicação. Durante o processo de recuperação, podemos analisar a capacidade de condução de corrente, o sincronismo dos sinais, os riscos de EMI e os caminhos térmicos. Isso possibilita a modificação, otimização ou remanufatura controlada da PCB, preservando a compatibilidade do sistema. Para placas obsoletas ou sem documentação, a restauração do sistema de interconexão geralmente é a etapa mais crítica para se obter uma reprodução confiável.
4, Crosstalk is caused by the electromagnetic coupling between the wires. The mutual capacitance causes the current to be combined, and the mutual inductance causes the coincidence voltage. The traces in modern circuits are very dense, so the clutter between the trace itself and the electromagnetic field generated by the traces around it is very serious. When the crosstalk voltage is large enough, it may cause serious functional problems of the circuit. On Printed Circuit Board Interconnection System, crosstalk is related to the length of the trace, the spacing of the lines, the direction of the transmitted signal in the line, and the termination mode and the condition of the reference ground plane.
