摘要:
A method of manufacturing a printed circuit board with a polymer thick-film (PTF) resistor (30) whose dimension can be defined with an improved precision by providing a circuit board (10) construction having a planar surface where the resistor is to be deposited. To achieve the desired board construction, the interconnect for the resistor (30) is pattern plated using a permanent photodielectric layer (18) as a plating mask instead of a sacrificial plating resist. The interconnect can be patterned before or after the (PTF) resistor is printed. The x and z dimensions (width and thickness, respectively) of the resistor are determined by the deposition process, while the y dimension (electrical length) is accurately determined by copper termination (26).

一种制造具有聚合物厚膜(PTF)电阻器(30)的印刷电路板的方法,其尺寸可以通过提供具有要沉积电阻器的平坦表面的电路板(10)结构而以更高的精度限定 。 为了实现所需的电路板结构,使用永久光致电介质层(18)作为电镀掩模而不是牺牲电镀抗蚀剂来对电阻器(30)的互连进行图案电镀。 可以在打印(PTF)电阻器之前或之后对互连进行图案化。 电阻器的x和z尺寸(分别为宽度和厚度)由沉积过程确定,而Y尺寸(电长度)由铜端接(26)精确确定。
