Njengoko sonke sisazi, i-PCB “yibhulorho” yokudibanisa zonke izinto zombane kwaye yeyona nto iphambili kwiimveliso ze-elektroniki. Inezicelo ezahlukeneyo, kubandakanya izixhobo ze-elektroniki zabathengi, izixhobo ze-elektroniki zeemoto, unxibelelwano, amayeza, iprojekthi yomkhosi, i-aerospace njalo njalo. Kule mihla, izixhobo ze-elektroniki zabathengi kunye nezixhobo ze-elektroniki zeemoto zifumana uphuhliso olukhawulezayo kwaye ziba ziintsimi eziphambili zesicelo. Okwangoku, ukuwelda kwe-PCB kutsale ingqalelo enkulu kubavelisi be-PCB. Ngoko ke, zeziphi iintlobo ze-PCB ezinokusetyenziswa kumatshini wokuwelda nge-laser? Makhe sijonge ngezantsi.
1. Into kufuneka inyibilikiswe
Kuthetha ukuba phantsi kobushushu obufanelekileyo, isinyithi esiza kunyibilikiswa kunye netin yokunyibilikisa zinokudibana ukuze zibe nomgangatho olungileyo we-alloy. Ayizizo zonke isinyithi ezinokudityaniswa kakuhle. Ukuphucula ukudityaniswa kwesinyithi, abasebenzisi banokwenza ukutywina ngetin okanye ukutywina ngesilivere kwisinyithi ukuthintela ukuxinana komphezulu wesinyithi.
2. Le nto kufuneka icoceke phezu komphezulu
Ukuze kudityaniswe i-soldering tin kunye nezinto eziza kunyibilikiswa, umphezulu wento kufuneka ucoceke. Nokuba kwizinto ezilungele ukunyibilikiswa, ifilimu ye-oxidation okanye i-oil stain inokwenzeka kumphezulu wento. Ke ngoko, ukuqinisekisa umgangatho wokunyibilikisa, umphezulu wento kufuneka ucoceke.
3. Sebenzisa i-powder yokukala efanelekileyo
Injongo ye-scaling powder kukususa ifilimu ye-oxidation kwinto eza kudityaniswa. Iindlela ezahlukeneyo zokuwelda kufuneka zisebenzise i-scaling powder eyahlukileyo. Kwi-welding ngokuchanekileyo kwe-elektroniki efana ne-PCB, i-rosin kufuneka isetyenziswe njenge-scaling powder ukuqinisekisa ukuthembeka kwe-welding.
4. Into kufuneka ifudunyezwe ukuya kubushushu obufanelekileyo
Ukuba ubushushu bokuwelda buphantsi kakhulu, i-alloy ayinakwenzeka. Kwaye ukuba ubushushu bokuwelda buphezulu kakhulu, i-welding flux iya kuhlala ikwimeko engeyiyo eutectic, nto leyo eya kunciphisa umgangatho we-welding flux kwaye kwimeko embi kakhulu, i-pad kwi-PCB iya kuwa.
5. Ukuwelda kufuna ixesha elifanelekileyo
Ixesha lokuwelda lithetha ixesha elichithwa kwimpendulo yamakhemikhali kunye neyomzimba kwinkqubo yokuwelda. Emva kokugqiba ubushushu bokuwelda, abasebenzisi kufuneka bagqibe ixesha elifanelekileyo lokuwelda ngokusekelwe kwimilo, umgangatho kunye neempawu zezinto eziza kuwelda. Ukuba ixesha lokuwelda lide kakhulu, izinto okanye iindawo eziweldayo kulula ukonakala. Ngokubanzi, indawo nganye akufuneki ithathe ngaphezu kwemizuzwana emi-5 ngexesha.
Ukuze umatshini wokuwelda we-laser we-PCB ugcine usemgangathweni wawo, kufuneka upholiswe ngokufanelekileyo yi-industrial chiller. I-S&A Teyu ibisoloko izinikele kwi-industrial chiller kangangeminyaka eli-19 kwaye inokubonelela ngee-industrial chillers kwiintlobo ezahlukeneyo zee-laser welding machines. Ii-recirculating chillers zilula ukuzisebenzisa, azinakugcinwa ixesha elide, zisebenza ixesha elide, kwaye azinakuthembeka. Amandla okupholisa aqala kwi-0.6KW ukuya kwi-30KW, nto leyo enokwanelisa iimfuno zokupholisa ezivela kubasebenzisi abahlukeneyo. Ukuba awuqinisekanga ukuba yeyiphi i-recirculating chiller mode onokuyikhetha, sithumelele i-imeyile ku marketing@teyu.com.cn
