This illustration distinctly shows the importance of using a fume extraction system, even when soldering only once in a while or for just a few hours a day. The captured particles are primarily condensed residues from flux. Without a filter system these particles ill be partly inhaled the operator with the remainder spread over the work object and workplace. In contrast, a proper filter system will eliminate not only the particles, but will also catch and eliminate dangerous gases created in the soldering process.

烟尘过滤（净化）原理:

用风机将烟雾抽入机箱，通过内置的滤芯进行过滤，主要能够起到过滤粉尘

、异味、有毒气体和杀灭部分细菌的作用。滤网又分：集尘滤芯、玻纤滤芯、

HEPA滤芯、活性炭滤芯等。其中最关键就是活性炭滤芯，它能起到分解有毒气体

和杀菌作用，特别是抑制二次污染。产品的特点是风机功能以及滤芯的质量决定

净化效果，机器的放置以及室内布局影响净化是否完全，室内净化效果是否均衡

。滤芯需定期更换。

烟雾组成成分及危害:
通常在焊接烟雾中有95％是焊料及助焊剂在高温下挥发出的微粒，这些微粒

飘浮在空气中在一定的光线照射下人眼可以观察到，即我们能够看到的烟雾。而

另外有5％是以气体方式散发在空气中，我们的肉眼是看不到的，而这些气体中

含有大量的一氧化碳、二氧化碳、甲醇、乙醇、甲烷、甲醛等有害性成分。
操作者长时间在以上环境下工作，吸入过量有毒物质，将会引起头痛、恶心、哮

喘、慢性支气管炎等症状，严重影响身体健康，同时也影响正常生产。
Hazardous smoke and fumes, harmful to your health if inhaled, are

present in many workplace environments. Operations using lead-free

solder, lasers, solvents, and glues are especially at risk.

Overexposure can lead to serious – and possibly long term – medical

problems.Health difficulties such as nosebleed, eye irritation, and

sore throat are occurring with increasing frequency in the workplace,

as are incidences of dermatitis, occupational asthma, and, in some

cases, permanent lung damage.

OCCUPATIONAL ASTHMA
“Occupational Asthma is a disease characterized by variable air flow

limitation and/or airway hyper-responsiveness due to causes and

conditions attributable to a particular occupational environment and

not to stimuli encountered outside the workplace.” (Bernstein et al

1993)

Fumes and gases in industrial areas are often dangerous to the people

working in those areas. Some of these substances are readily visible

or have a distinct odor; others are invisible and odorless. Many are

toxic and can lead to allergic reactions, sometimes progressing to occupational asthma.

Occupational asthma is a major issue in electronics manufacturing

because when a worker develops occupational asthma, they must be

removed from the working area, sometimes permanently. In some

countries, cases of occupational asthma due to flux fumes and/or

isocyanates have already lead to legal claims against employers.

Occupational asthma is often indicated by symptoms common to hay

fever – an itchy, blocked, or runny nose, often accompanied by

sneezing and glazed, itchy, or watering eyes.
LEAD-FREE SOLDER

The transition to lead-free soldering has reduced strain on the

environment, but for the operator, the hand soldering process has

become more dangerous. The lead in the solder is gone, but to get the

solder wire to flow properly, substantially more flux must be used.

The temperature needed to create a good solder joint using lead-free

solder is also higher, causing a stronger reaction within the flux and

creating more solder smoke with a greater number of particles. Lead-

free soldering produces up to 250 % more particles between 0.5 and 1.0

microns in diameter, the size that is the most dangerous to inhale. In

addition to particles, solder smoke can contain isocyanates,

aldehydes, and other unhealthy substances.
Lead-free soldering causes up to 250 % more particles in the breathing

zone … roughly 20 million particles between 0.3 and 1.0 microns in

diameter per cubic foot, or about 700 million particles per cubic

meter.

How particles of different size get caught in different parts of the

human respiratory system:
