    • PURPOSE: A PCB manufacturing method is provided to fill up a solder resist effectively into a sunken part like a blind via hole. CONSTITUTION: A solder resist is covered on a blind via hole(30) exposed by a window screen(40). In a time, the solder resist could not be filled up to inside of the blind via hole because of inside left air. So a PCB(20) coated by the solder resist is carried to a low pressure like 1/10 of atmospheric pressure for 1-2 min. to suck out the inside air. The vacant space of the air is replaced by the solder paste. Then the solder paste is sprayed again on overall space of the PCB to flatten the PCB surface. In next, dry and hardening processes are performed, so a damage caused by a thermal difference between air and solder paste is prevented.
    • 目的:提供PCB制造方法,以有效地将阻焊剂填充到诸如盲孔的凹陷部分中。 构成:在由窗户(40)暴露的盲孔(30)上覆盖阻焊剂。 在一段时间内,由于内部的左侧空气,阻焊剂不能填充到盲孔的内部。 因此,由阻焊剂涂覆的PCB(20)被承载为大气压力的1/10的低压,持续1-2分钟。 吸出内部空气。 空气的空隙由焊膏代替。 然后将焊膏再次喷涂在PCB的整个空间上以使PCB表面变平。 接下来,进行干法和硬化处理,从而防止由空气和焊膏之间的热差引起的损伤。

    • PURPOSE: A manufacturing method of a PCB(Printed Circuit Board) is provided to form a carrier layer on a base substrate, thereby improving the planarity of a circuit layer, thinning the thickness of the PCB, and forming a fine circuit pattern. CONSTITUTION: A manufacturing method of PCB comprises the following steps of: preparing a base substrate(110); forming a carrier layer on the base substrate; forming a through via hole passing through the carrier layer and the base substrate; forming a plating layer on the top of the carrier layer and the inner wall of the through via hole; charging conductive paste in the though via hole; removing the plating layer formed on the carrier layer; removing the carrier layer; and forming a circuit layer(150) on the base substrate.
    • 目的:提供PCB(印刷电路板)的制造方法,以在基底基板上形成载体层,从而提高电路层的平面度,减薄PCB的厚度,形成精细电路图案。 构成:PCB的制造方法包括以下步骤:制备基底(110); 在基底基板上形成载体层; 形成穿过所述载体层和所述基底的通孔; 在载体层的顶部和通孔的内壁上形成镀层; 在通孔中充电导电膏; 去除形成在载体层上的镀层; 去除载体层; 以及在所述基底基板上形成电路层(150)。
