I don't know if we have enough solder to finish these circuit boards.

我们好像没有足够焊料来焊住这些电路板。

But that only measures the temperature at the surface of the solder, rather than throughout the material.

但这只测量了焊料表面，而不是整个材料。

Oh, they went to the store to get solder, which is metal you melt to make science things.

他们出去买焊料了，就是那种能用火熔化做科学东西金属。

The boys had to drive all the way to San Bernardino for the solder and got a flat.

他们俩为了焊料一路开到圣贝纳迪诺，结果在路上爆胎了。

How can you call yourself a scientist and run out of solder?

你怎么好意自称科学家 结果没焊料？

That makes sense. Do you think the solder we're using could be a problem?

答：这是有道理。您认为我们使用焊料会有问题吗？

If the actual temperatures deviate from these ranges, it can cause incomplete solder fusion, leading to weak joints.

如果实际偏离这些范围，可能会导致焊料熔合不完全，从而导致接头脆弱。

If it's too high or too low, it can affect the solder deposition and joint formation.

如果它太高或太低， 都会影响焊料焊缝形成。

Clogged nozzles can cause uneven solder flow, and an improper wave height can result in insufficient or excessive soldering.

堵塞喷嘴会导致焊料流动不均匀，而不适当波高会导致焊接不足或过。

Tin's comeback is thanks in part to a European Union regulation that banned lead in solder, meaning tin became ubiquitous in electronic circuits.

锡卷土重来部分归功于欧盟禁止焊料中使用铅法规，这意味着锡在电子电路中变得无处不在。

Also important would be to store food and drink in preferably glass containers, certainly to not store food in tins that can have solder inside them containing lead.

同样重要是，将食物饮料存放在首选玻璃容器中，绝对不要将食物存放在可能含有含铅焊料锡罐内。

10. Question: Name one advantage of using lead - free solder in PCBA. Answer: It is more environmentally friendly as it reduces the release of toxic lead into the environment.

10. 问题：说出在 PCBA 中使用无铅焊料一个优点。答： 它更环保，因为它减少了有毒铅释放到环境中。

21. Question: What is the purpose of a solder mask in PCBA? Answer: It prevents solder from bridging between pads, protects the PCB from environmental factors, and helps in component identification.

21. 问题： PCBA 阻焊层用途是什么？答案： 它可以防止焊料在焊盘之间架桥，保护 PCB 免受环境因素影响，并有助于识别元件。

72. Question: How can we reduce the risk of solder spatter during the soldering process in PCBA? Answer: By controlling the solder volume, using proper soldering techniques, and adjusting the soldering temperature and time.

72. 问题：如何降低 PCBA 焊接过程中出现焊料飞溅风险？答： 通过控制焊料量，使用适当焊接技术，并调整焊接时间。

56. Question: In PCBA, how can we prevent solder wicking? Answer: By controlling the solder volume, optimizing the component lead length, and adjusting the soldering temperature and time to avoid excessive solder climbing up the leads.

56. 问题：在 PCBA 中，我们如何防止芯吸？答案： 通过控制焊料量，优化元件引线长，调整焊接时间，以避免过多焊料爬上引线。

51. Question: How does the cleanliness of the PCB surface impact the soldering process in PCBA? Answer: A dirty PCB surface can prevent proper wetting of the solder, leading to poor solder joints, increased resistance, and possible electrical failures.

51. 问题：PCB 表面清洁如何影响 PCBA 中焊接过程？答案： 肮脏 PCB 表面会妨碍焊料适当润湿，从而导致焊点不良、电阻增加可能电气故障。
