In the printing industry, photo platemaking is often used to produce pictures on paper. That is, by taking photos, the picture of the bottom plate, etched on the copper plate or zinc plate, with this copper plate or zinc plate, you can print a lot of pict
It is characterized by simple production process, low cost, short cycle, good wear resistance, electrical conductivity, can make the single panel to achieve high density, miniaturization, lightweight, suitable for TV, telephone, video recorder and electro
Basically, the goal of setting up the test area is to test the components on the circuit board for specification and weldability.
Integrated circuit board is the use of semiconductor production process, in a small monocrystalline silicon wafer production of many transistors and resistors, capacitors and other components, and in accordance with the multi-layer wiring or tunnel wiring
Then use the same method to separate the other pins of the integrated circuit from the circuit board, and finally you can remove the entire integrated circuit.
Denser PCBS, higher bus speeds, and analog RF circuits pose unprecedented testing challenges that require careful design, thoughtful testing methods, and appropriate tools to provide reliable test results.
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.
PCB design is based on the circuit schematic diagram to achieve the function required by the circuit designer. Excellent design can save production cost, achieve good circuit performance and heat dissipation performance.
especially since The State Council issued Several Policies to Promote the High Quality Development of the Integrated Circuit Industry and Software Industry in the New Era this year, the integrated circuit industry has become a new industry tuyere.
PCB with insulation board as the base material, at least attached with a conductive graphic, and cloth holes, used to replace the chassis of the previous device electronic components, to achieve the mutual connection between electronic components.
In PCB board design and circuit board production, engineers not only need to prevent PCB board accidental encounters during the manufacturing process, but also need to avoid design errors.
With increasing frequency, it becomes more and more difficult to control the phase consistency of printed circuit board materials. Accurately predicting the phase change of circuit board materials is not a simple or routine task.
