自动点胶机焊接过程中，会遇到焊接不良的问题，这些问题具体首要体现有漏焊、虚焊、连焊、焊点不光滑、堆锡、拉尖等现象的，针对这些焊接不良问题，认真观察，找对形成这些不良的原因，然后在有针对性的去处理。

　　In the welding process of automatic dispensing machine, there will be problems of poor welding. These problems are mainly manifested in the following aspects: leak welding, virtual welding, continuous welding, non-smooth solder joints, tin-surfacing and tightening. In view of these problems, we should observe carefully, find out the causes of these defects, and then deal with them pertinently.

　　1、漏焊。漏焊一般是指在焊接过程中，焊盘上没有锡的现象。自动点胶机呈现这种状况的原因大致有两点，一是烙铁头没有接触到焊点，这个时候咱们就要调整该点的坐标，使烙铁头接触到焊点，这样就不会呈现漏焊;在一个就是焊盘表面氧化比较严重，锡根本粘不在上面。

　　1. Leakage welding. Leakage welding generally refers to the phenomenon that there is no tin on the pad during the welding process. There are two reasons for this situation in automatic dispensing machine. One is that the soldering head does not touch the solder joint. At this time, we need to adjust the coordinates of the spot so that the soldering head touches the solder joint, so that there will be no leakage soldering; the other is that the surface of the soldering pad is oxidized seriously and the tin is not adhered to it at all.

　　2、虚焊。虚焊一般是指在焊接过程中看上去焊点还可以，实际上焊接时不捞的或是透锡量不行。形成这种状况的原因首要是烙铁头在焊盘上的停留时间不行或是温度过低形成的。因而咱们只需延伸烙铁头的停留时间或是升高温度就可以处理的

　　2. Virtual welding. Virtual soldering generally refers to the solder joint can be seen in the process of welding, in fact, it is not fished or tin penetration is not good. The main reason for this situation is that the retention time of the soldering head on the pad is not good or the temperature is too low. So we only need to extend the residence time of the soldering head or raise the temperature to deal with it.

　　3、连焊。连焊一般是指紧邻的几个两个焊点或是几个焊点的焊盘链接在一起的现象。形成此种现象的原因要么是送锡量太多或是两个点之间的空隙太小所形成的。遇到这种状况，应该削减锡量，然后在看是否是烙铁头的方位是否正确，如不正确，应及时进行调整

　　3. Continuous welding. Continuous welding generally refers to the phenomenon that several adjacent solder joints or pads of several solder joints are linked together. The reason for this phenomenon is either too much tin feeding or too small gap between the two points. In this case, first of all, tin should be reduced, and then to see if the position of the iron head is correct, if not correct, timely adjustments should be made

　　4、堆锡。堆锡一般是指焊点时一个球形，管脚腿没有漏出来的现象。自动点胶机呈现此种现象的原因主要的是由于送锡量太大形成的，此时只需削减锡量就可以处理的，还有一种原因是指管脚腿太短，没有显露焊盘所形成的。

　　4. Tin heap. Tin stacking generally refers to a spherical solder joint, which does not leak out of the leg. The main reason for this phenomenon in automatic dispensing machine is that the tin feeding amount is too large, which can be handled by reducing the tin content. Another reason is that the leg of the pipe is too short and the solder pad is not exposed.

　　5、焊点不光滑、拉尖。焊点不光滑、拉尖是指焊过之后焊点成型欠好或是有毛刺并有拉尖的现象。此种原因首要是由于锡的流动性欠好形成的，这个有时候也和咱们参数的设置欠好也是有一定原因的，要么就是停留时间过长，形成助焊剂蒸发过快，在烙铁头的抬起过程中就会形成拉尖的现象。这个假如通过参数的设置无法处理的话，咱们就要考虑锡丝的问题。

　　5. The solder joint is not smooth and sharp. Non-smooth solder joints and pointed solder joints refer to the phenomenon of poor solder joint formation or burr and pointed solder joints after soldering. The main reason for this is that the fluidity of tin is not good. Sometimes this is also due to the poor setting of our parameters. Either the residence time is too long and the flux evaporates too fast, which will lead to the phenomenon of tightening during the lifting process of the soldering head. If this can not be handled by setting parameters, we should consider the problem of tin wire.

　　当然在焊接过程中，假如是因为烙铁头该换而没有及时更换的话，呈现这种不良焊点的几率也是很大的，因而除了是该更换烙铁头的原因之外，其他的咱们一定要对症下药的。

　　Of course, in the welding process, if it is because the soldering head should be replaced and not replaced in time, the probability of showing such bad solder joints is also very large, so in addition to the reason for replacing the soldering head, we must take appropriate medicine.
