Electrical connection or signal transmission between 70 pieces of hyphae. Under the trend of large-scale development and functional requirements, I two = elephants and its _ are the components of circuit surface adhesion components The demand for printed circuits has increased sharply, but the distance between adjacent components in the aforementioned trend circuits has been shortened, and the probability of listening to gangsters has increased significantly, which directly affects the stability of circuit work. Rise and fall signals may have to pass through the M core and the transmission wheel (such as electrical connection through the through hole or ^ tiger transmission), which increases the situation of line impedance mismatch and line noise reduction printed by the Central Standard Staff Consumer Cooperative of the Ministry of Economic Affairs 3 and = / € ^ Increase in the number of pieces' will reduce the production yield relatively and thus increase the manufacturing cost. Table 2: The increase in the number of components 'is not less than the printed circuit board can know' the various problems derived from high density printed circuits.

Therefore, the drawing company has different (resistance coefficient) / tf # #, (extent degree) 'and Use L (length), W (width) to produce the required resistance (R). And with the current multi-layer printed circuit manufacturing technology that is used very often, the resistors are made in the structure of the printed circuit board to form a built-in resistor, and the resistor built in the structure of the printed circuit board can effectively replace the printed circuit board table / jin. The required resistive element can therefore reduce the number of components and the area occupancy of the surface of the printed circuit board. Existing built-in resistance, capacitors are often formed in other ways. For existing multilayer printed circuit boards, they often make two power supply layers with different potentials (such as VCC and GND) look up > + „W, ^ Sin is near, using the large copper surface produced by the two of them to adjust the voltage. IX adjust the voltage. The formula is as follows: C (capacitance) = (dielectric coefficient) x Α (area) mm), because !, "Dielectric constant" is controlled by the change of material characteristics ^ (area) and d (distance), which can restrain the required capacitance.乂 Control the production of brush ==, embed the passive components such as resistors and capacitors in the printed circuit board * to effectively reduce the number of surface components and release the irresistible ...: The resistors and embedded capacitors are built in °, such as 'Failed to complete in the same process, causing (please read the precautions on the back before filling this page)
