- Facilitating shift and new configuration jump contact wiring board, cuddle inserts system of line, motherboard. 便于移动和重新配置跳接点的接线板、搂插线、底板系统。
- 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。
