Inzuzo ye-SMTreflow oveninkqubo kukuba ubushushu kulula ukulawula, i-oxidation inokuphetshwa ngexesha lenkqubo yokuthengisela, kunye neendleko zemveliso yokuvelisa kwakhona kulula ukulawula.Kukho iseti yombane yokufudumeza iisekethe ngaphakathi kwesi sixhobo, esifudumeza initrogen kubushushu obuphezulu ngokwaneleyo kwaye uyivuthele kwibhodi yesekethe apho amacandelo afakwe khona, ukuze i-solder kumacala omabini amacandelo anyibilike kunye neebhondi kunye neyona nto iphambili. ibhodi.I-TYtechizakwabelana ngenye yendlela yokuphucula ye-SMT reflow inkqubo yokuphinda ithengiselwe apha.
1. Kuyimfuneko ukuseta i-SMT yesayensi ye-reflow soldering curve kwaye uqhube uvavanyo lwexesha langempela kwi-curve yeqondo lokushisa rhoqo.
2. I-Solder ngokuhambelana ne-reflow soldering direction ngexesha loyilo lwe-PCB.
3. Ngexesha lenkqubo ye-SMT reflow soldering, ibhanti lokuhambisa kufuneka lithintelwe ukuba lingangcangcazeli.
4. I-reflow soldering effect yebhodi yokuqala eprintiweyo kufuneka ihlolwe.
5. Ingaba i-SMT i-reflow soldering yanele, ingaba i-solder joint solder igudile, ingaba imilo ye-solder ye-solder yi-half-moon, imeko yeebhola ze-solder kunye neentsalela, imeko ye-solder eqhubekayo kunye ne-solder virtual.Khangela kwakhona izinto ezifana nokutshintsha kombala kumphezulu we-PCB.Kwaye ulungise ijika lobushushu ngokweziphumo zokuhlola.Ngexesha lenkqubo yokuvelisa ibhetshi, umgangatho we-welding kufuneka uhlolwe rhoqo.
6. Gcina i-SMT reflow soldering rhoqo.Ngenxa yokusebenza kwexesha elide lomatshini, izinto ezingcolisayo eziphilayo okanye ezingabonakaliyo ezifana ne-rosin eqinisiweyo ziqhotyoshelwe.Ukuze kuthintelwe ungcoliseko lwesibini lwe-PCB kwaye kuqinisekiswe ukuphunyezwa kwenkqubo kakuhle, ukugcinwa rhoqo kunye nokucoca kuyadingeka.
