- Do the printed wiring boards have to be lead-free? 印刷線(xiàn)路板必須是無(wú)鉛的嗎?
- In the multilayer printed circuit boards (PCBs), the through-hole via transitions are always utilized to link the signal traces between different layers. 在多層印刷電路板當中,連通柱結構總是被用來(lái)連結位于不同層的傳輸線(xiàn)。
- Estimates are that 60-70% of printed wiring boards are tin-lead solder coated, usually by hot air solder leveling (HASL). 據估計,60-70%25的印刷線(xiàn)路板都帶有錫-鉛涂層,該涂層通常借助熱空氣焊料均涂(HASL)方法進(jìn)行涂敷。
- In dielectrics are available on the electrical connections between components of conducting a graphic that is referred to as printed wiring. 在絕緣基材上提供元器件之間電氣連接的導電圖形,稱(chēng)為印制線(xiàn)路。

- 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,因為在厚的核心基板30中容納了片狀電容器20,所以印刷布線(xiàn)板不會(huì )變厚。
- 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. 焊料涂層被涂敷到印刷線(xiàn)路板的銅表面上,不僅可以保持可焊性,同時(shí)還可以保護銅導體免受環(huán)境腐蝕。
- It is easier to print wire services dispatches than have a reporter on the beat. 刊登通訊社的電訊稿比派記者到現場(chǎng)采訪(fǎng)要容易。
