根据待加工PCB所需要的电阻器的电阻值,选定方阻阻值的平面电阻材料,依据电阻材料的方阻特性,由电阻计算公式计算出电阻器长度和宽度的准确值,从而确定电阻器的图形设计。埋置碳膜电阻的制作是在PI板上旋转设计好的电阻器模板,通过丝网印刷将调制好的纪念碑油墨印刷到PI板上,经过固化得到埋置电阻。通过层压制作PI复合板,在PI复合板两个表面,印刷纳米银导电油墨制作PCB线路。再通过银浆贯孔,实现埋置电阻与PCB线路的贯通,制成埋置电阻的全印刷PCB板。
According to the resistance value of the resistor needed for the PCB to be processed, the square resistance value of the selected square resistance material is calculated according to the square resistance characteristic of the resistance material, and the exact value of the length and the width of the resistance is calculated by the resistance calculation formula so as to determine the resistance Graphic design of the device. Buried carbon film resistor is made by rotating the designed resistor template on the PI board, and printing the modulated monument ink onto the PI board through screen printing, and then curing the embedded resistor. PI laminates made by lamination, in the PI composite plate on both surfaces, printed nano-silver conductive ink production PCB circuit. And then through the silver paste through holes to achieve the penetration of embedded PCB resistors and lines, made of embedded resistors printed PCB board.
