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

我们好像没有足够料来电路板。

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

但只测量了料表面的温度，而是整个材料的温度。

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

他们出去买料了，就是那种能用火熔化做科学东西的金属。

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 结果没料？

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

答：是有道理的。您认为我们使用的料会有问题吗？

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

如果实际温度偏离范围，可能会导致料熔合完全，从而导致头脆弱。

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， 都会影响料沉积和缝形成。

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

堵塞的喷嘴会导致料流动均匀，而适当的波高会导致足或过度。

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

锡的卷土重来部分归功于欧盟禁止料中使用铅的法规，意味着锡在电子电路中变得无处在。

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.

同样重要的是，将食物和饮料存放在首选的玻璃容器中，绝对要将食物存放在可能含有含铅料的锡罐内。

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 中使用无铅料的一个优点。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 阻层的用途是什么？答案： 它可以防止料在盘之间架桥，保护 PCB 免受环境因素的影响，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 过程中出现料飞溅的风险？答： 通过控制料量，使用适当的技术，并调整温度和时间。

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： 通过控制料量，优化元件引线长度，调整温度和时间，以避免过多的料爬上引线。

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 表面的清洁度如何影响 PCBA 中的过程？答案： 肮脏的 PCB 表面会妨碍料的适当润湿，从而导致点良、电阻增加和可能的电气故障。
