The second method is to let the designer of the circuit board factory beside a piece of copper foil around the circuit board pad, the attachment area is large, the pad is not easy to fall off, if there is no space around the pad beside the copper foil, th
With the development of the production of printed led circuit boards in the direction of high precision and high density, the production of printed boards is more energy saving, emission reduction and environmental protection.
Among the four ceramic circuit board manufacturing technologies, laser activated metallization will become the main process
With the gradual development of electronic products to fine and intelligent, more materials are applied in them. Understand the characteristics of various materials used in the product, and adopt more suitable laser processing technology and process.
Not paying attention to the packaging of products can bring immeasurable benefits.
With the development of computer technology, printed board CAD technology has made great progress, PCB production technology level also continues to multi-layer, fine wire, small aperture, high density direction rapidly improved.
Automated testing is essential to validate the manufacture of printed circuit boards. The bare board test will check that the wood-based board has good connectivity, while the ICT and fly pin tests will verify the board assembly and welded connections.
Circuit board manufacturing, circuit board design and PCBA processing manufacturers explain the original PCB high-frequency circuit board manufacturing process
PCB manufacturing, PCB design, PCBA processing manufacturer will explain the manufacturing of flexible PCB for pcb proofing
The circuit board manufacturer will explain the key points of pre manufacturing engineering design of multilayer circuit boards
The circuit board makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances.
Analysis on the causes of lead-free circuit board fabrication -------- The harm of lead
Description method is to manufacture the circuit board requires the least tools, manufacturing process is the simplest of a method, but the accuracy is not very high, suitable for beginners.
