如何解决自动焊锡机虚焊的问题

保持焊接头部清洁，一般自动焊锡机在高温工作中，容易产生飞尘，或者为通电的自动焊锡机烙铁头长期处于高温状态，其表面很容易氧化或烧死，使烙铁头导热性能变差而影响焊接质量。因此，自动焊锡机为了能提高烙铁头的寿命，很多焊锡机上面设置了自动吹气装置。

Keep welding head clean, general automatic solder machine in high temperature work, easy to produce flying dust, or for the power of automatic solder machine soldering iron head long in high temperature state, its surface is easy to oxidize or burn to death! The heat conduction performance of soldering iron head is worse and the welding quality is affected. Therefore, in order to improve the life of soldering iron head, the automatic solder machine has set up an automatic blowing device on the top of the solder machine.

焊锡机

焊锡机工作时间不宜过长，焊接时间的恰当运用也是焊锡工艺的重要环节。如果是电路板插件的焊接，一般以2～3s为宜。焊接时间过长，焊料中的助焊剂完全挥发，失去助焊作用，使焊点表面氧化，造成焊点表面粗糙、发黑、不光亮、带毛刺等缺陷。助焊剂的作用就是使锡丝在接触高温状态中的烙铁头后快速地使焊盘铺满锡，锡丝中的助焊剂含量越高，融化后的锡铺满焊盘的速度越快。自动焊锡机的同行之中，对锡丝助焊剂含量要求都在3%左右。

The working time of solder machine should not be too long, and the proper application of welding time is also an important link of solder process. If it is the circuit board plug-in welding, generally to 2~3s is appropriate. Welding time is too long, solder in the flux completely volatile, loss of welding effect, so that the surface of the solder joint oxidation, resulting in rough surface of the solder joints, blackening, not bright, with burrs and other defects. The function of the flux is to make the solder in contact with the high temperature state of the soldering iron head quickly make the pad covered with tin, the higher the flux content in the tin wire, the faster the melting tin is covered with pads. Automatic solder machine in the peer, the solder flux content requirements are around 3%.

自动焊锡机出现虚焊的解决方法，总的来说就是烙铁头接触焊盘，尽量压到，方便导热。 焊接的温度要适当，不能过高、也不能过低（控制温度很重要）焊点凝固的过程中，切记不要用手触碰焊点。焊点在未完全凝固前，即使有很小的震动也会使焊点变形，引起虚焊。因此，在烙铁头撤离之前对焊接件要予以固定，预留焊点凝固的时间。

Automatic solder machine appears virtual welding solution, in general, is soldering iron head contact pad, as far as possible pressure, convenient thermal conductivity. Welding temperature should be appropriate, can not be too high, can not be too low (control temperature is very important) welding point solidification process, remember not to touch the solder joint with the hand. Before the solder joint is completely solidified, even if there is a small vibration will make the solder joint deformation, causing virtual welding. Therefore, the welding parts should be fixed before the soldering iron head is evacuated, and the time of solidification of the solder joints should be reserved.
