保持焊接頭部清潔，一般自動(dòng)焊錫機(jī)在高溫工作中，容易產(chǎn)生飛塵，或者為通電的自動(dòng)焊錫機(jī)烙鐵頭長(zhǎng)期處于高溫狀態(tài)，其表面很容易氧化或燒死，使烙鐵頭導(dǎo)熱性能變差而影響焊接質(zhì)量。因此，自動(dòng)焊錫機(jī)為了能提高烙鐵頭的壽命，很多焊錫機(jī)上面設(shè)置了自動(dòng)吹氣裝置。

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.

焊錫機(jī)

焊錫機(jī)工作時(shí)間不宜過(guò)長(zhǎng)，焊接時(shí)間的恰當(dāng)運(yùn)用也是焊錫工藝的重要環(huán)節(jié)。如果是電路板插件的焊接，一般以2～3s為宜。焊接時(shí)間過(guò)長(zhǎng)，焊料中的助焊劑完全揮發(fā)，失去助焊作用，使焊點(diǎn)表面氧化，造成焊點(diǎn)表面粗糙、發(fā)黑、不光亮、帶毛刺等缺陷。助焊劑的作用就是使錫絲在接觸高溫狀態(tài)中的烙鐵頭后快速地使焊盤鋪滿錫，錫絲中的助焊劑含量越高，融化后的錫鋪滿焊盤的速度越快。自動(dòng)焊錫機(jī)的同行之中，對(duì)錫絲助焊劑含量要求都在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%.

自動(dòng)焊錫機(jī)出現(xiàn)虛焊的解決方法，總的來(lái)說(shuō)就是烙鐵頭接觸焊盤，盡量壓到，方便導(dǎo)熱。 焊接的溫度要適當(dāng)，不能過(guò)高、也不能過(guò)低（控制溫度很重要）焊點(diǎn)凝固的過(guò)程中，切記不要用手觸碰焊點(diǎn)。焊點(diǎn)在未完全凝固前，即使有很小的震動(dòng)也會(huì)使焊點(diǎn)變形，引起虛焊。因此，在烙鐵頭撤離之前對(duì)焊接件要予以固定，預(yù)留焊點(diǎn)凝固的時(shí)間。

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.
