- Estimates are that 60-70% of printed wiring boards are tin-lead solder coated, usually by hot air solder leveling (HASL). 据估计,60-70%25的印刷线路板都带有锡-铅涂层,该涂层通常借助热空气焊料均涂(HASL)方法进行涂敷。
- Further, since the chip capacitors (20) are received in a thick core board (30), there is no possibility of thickening the printed wiring board. 另外，因为在厚的核心基板30中容纳了片状电容器20，所以印刷布线板不会变厚。
- The solder coatings are applied to the copper surfaces of the printed wiring board to preserve solderability and protect the copper conductors from environmental corrosion. 焊料涂层被涂敷到印刷线路板的铜表面上,不仅可以保持可焊性,同时还可以保护铜导体免受环境腐蚀。
- Enthone manufactures, markets and distributes its functional, decorative and electronic processes that are used in printed wiring board (PWB), semiconductor, automotive, aerospace, jewelry, and hardware and plumbing applications. 乐思生产并销售其功能性、装饰性及电子电镀工艺，这些工艺适用于印刷电路板、半导体、汽车、航空、珠宝、五金及卫浴等工业。。
- Arranging chip capacitors (20) in a printed wiring board (10) makes it possible to reduce the distance between an IC chip (90) and the chip capacitor (20) and to reduce the loop inductance. 因为在印刷布线板10内设置了片状电容器20，所以能够缩短IC芯片90与片状电容器20的距离，降低环线电感。
