Compared with other types of circuit boards, the requirements of power circuit boards are high reliability and special copper thickness requirements. And these two points are difficult to control for circuit board manufacturers, so how to produce high-reliability power circuit boards?Next, author from qihe smt pick and place machine will take you to understand described from the following four aspects:<\/p>\n\n\n\n

a. In terms of material selection: the power circuit board requires high stability, so in terms of material selection, attention should be paid to the selection of medium and high TG plates.<\/p>\n\n\n\n

b. Control of copper thickness: Under the same line width design, the thicker the copper (that is, 2OZ thicker than 1OZ), the greater the current it can carry, so the power circuit board has special requirements for copper thickness, according to the application of the power circuit board. Different fields have different copper thickness requirements.<\/p>\n\n\n\n

c. Control of ink thickness: For thick copper power circuit boards, the circuit is easy to expose copper and turn red, so it is necessary to do two solder masks to thicken the thickness of the green oil.<\/p>\n\n\n\n

d. Quality control: The high reliability of power circuit boards requires stricter quality control, including AOI of the inner layer, copper thickness test of electroplating, AOI of the outer layer, electrical performance test, reliability test, etc. The management and control of a link are interlinked and indispensable.<\/p>\n\n\n\n
