PCB is the printed circuit board, also known as printed circuit board. It is not only the carrier for the interconnection of electronic components, but also the backbone of the platform supporting electronic components. It is the most basic component of electronic products.
Since mankind entered the electronic age, the importance and technical level of PCB have been continuously enhanced. Now, in the stage of intelligent informatization, new applications have been born continuously. 5g, wearable devices, automotive central control screen, service robots and other new fields refresh our cognition day by day, and the technical requirements of PCB are becoming higher and higher. In this case, it is the best stage for laser technology to show its skills.
Compared with the past, PCB processing changes are most obvious in two days: 1. Higher requirements for processing precision and 2. Higher requirements for processing intelligence.
The first is machining precision. From mobile phones to watches, from computers to VR, smart devices are getting smaller and smaller, but their functional performance is getting stronger and stronger. PCB becomes smaller and thinner, but more and more electronic components need to be accommodated. Therefore, the requirements for machining precision are naturally higher and higher.
The traditional processing methods such as cutting tool, milling cutter and Gong cutter have unavoidable disadvantages such as burr, dust and mechanical stress, which will inevitably affect and damage PCB. In the increasingly high precision requirements, laser technology stands out and becomes a new solution.
As a laser for non-contact processing, precision processing and one-time forming can reach the micron level, with no burr, no stress, smooth edge and clear line. It is a natural choice for PCB processing.
On the other hand, intelligent processing is also the unique advantage of laser. Electronic products have fast iteration speed and many product tests and small-scale changes, which requires the equipment to have the ability of rapid response. Laser equipment equipped with intelligent control system usually only needs to import corresponding drawings to start a new round of processing. The process does not need manual supervision, and it can adapt to rapid changes.
At the same time, the modern supply chain system has a set of complete and strict requirements for traceability. There should be complete records at every step from warehousing to production, to detection and delivery. In this process, laser marking can give products unique identity. This marking method has the advantages of low cost, no pollution, difficult to change and no wear after marking. It is the most ideal solution for the traceability system.
