Ngaba uyawazi umsebenzi we-PCB solder mask? Zeziphi iinketho kwi-PCB solder imaski?
I-IPC iseke umgangatho wokuvavanya imaski ye-solder njengesikhokelo soshishino kubavelisi bezinto eziphathekayo, ii-OEM, kunye nabavelisi be-PCB. I-IPC SM-840D ihlela iileya zemaski ye-solder, iKlasi T kunye noHlelo H, lushwankathelwe ngolu hlobo lulandelayo:
I-T-Telecommunications: kubandakanywa iikhompyutha, izixhobo zonxibelelwano, oomatshini borhwebo abantsonkothileyo, izixhobo kunye nezicelo ezithile ezingabalulekanga zomkhosi. Uluhlu lwemaski ye-solder kulolu hlobo lwebhodi yesekethe lufanelekile kwimveliso ephezulu yorhwebo kunye nezoshishino ezifuna ubomi obude benkonzo kodwa abubeki engozini ubomi ukuba inkonzo iphazamisekile.
H - Ukuthembeka okuphezulu / umkhosi: kubandakanywa nokusebenza okubalulekileyo okuqhubekayo, ixesha lokunciphisa izixhobo ezingenakunyamezeleka, kunye / okanye izixhobo eziyiprojekthi yokuxhasa ubomi. Uluhlu lwemaski ye-solder kulolu hlobo lwebhodi yesiphaluka lufanelekile kwizicelo ezifuna ukuqinisekiswa kwezinga eliphezulu kunye nenkonzo engaphazamisekiyo.
Ngaba uyawazi umsebenzi we-PCB solder mask?
1. Ukulibazisa inkqubo yokwaluphala:Ukuthintela umonakalo kwi-PCB ebangelwa yimisebe ye-ultraviolet, nciphisa izinga lokuguga kwezinto, ngakumbi kwiibhodi zeesekethe ezivezwe kwiindawo ezikhanyayo zangaphandle okanye ezinamandla ixesha elide. Imaski ye-Solder inokwenza ifilimu yokukhusela kwi-PCB, ukukhusela isiphaluka kumonakalo wangaphandle womzimba, uthuli, umswakama, kunye nezinto zeekhemikhali, kunye nokwandisa ubomi benkonzo yebhodi yesekethe.
2. Ukukhuselwa kwe-insulation: Umaleko we-mask we-solder unomsebenzi omhle wokugquma. Ngokuyigubungela ngokuchanekileyo kwiindawo ezingenayo i-welding, imaski ye-solder inokwahlula ngokufanelekileyo iisekethe ezahlukahlukeneyo kwibhodi yesekethe, ukuphepha iisekethe ezimfutshane kunye neziphene zombane ngexesha lenkqubo yokuthengisela, ukuphepha umonakalo onokwenzeka wesiphaluka, kunye nokuphucula ukusebenza kombane kunye nokhuseleko lwemveliso.
3. Ukuphucula umgangatho we-soldering: Imaski ye-Solder inokuthintela i-solder ekutshizeni kwiindawo ezingadingi i-soldering, iqinisekisa ukucoceka kunye nokuchaneka kwendawo yokuthengisa. Oku kunceda ukuphucula umgangatho we-soldering kunye nokunciphisa iziphene zokuvelisa.
4. Phucula inkangeleko:Imaski ye-Solder yenza umphezulu ogudileyo kunye nofanayo kwi-PCB, enganqweneleki kuphela ngobuhle kodwa ikwalungele ukuleyibhelishwa okulandelayo, ushicilelo kunye nezinye iinkqubo, ukuphucula umgangatho wenkangeleko iyonke yemveliso.
5. Ukusebenza okuphuculweyo kwe-insulation:Umaleko we-mask we-solder unomsebenzi olungileyo wokugquma, onokuthi uphucule ukufakwa kombane kwePCB, ukunciphisa ukuvuza okunokwenzeka kunye nokuphazamiseka kombane, kunye nokuqinisekisa ukusebenza okuqhelekileyo kwesekethe.
6. Ukuququzelela uvavanyo:Ngexesha lenkqubo yokuvelisa i-PCB, umaleko we-mask we-solder unokukhusela isekethe kwizixhobo zoomatshini ezinjengezikhonkwane zovavanyo, ngelixa uququzelela uvavanyo lokufakwa kwepini kunye nokuhlola okubonakalayo, ukuphucula ukusebenza kovavanyo kunye nokuchaneka.
7. Ukhuseleko lokusiNgqongileyo kunye nokuThotyelwa kweMigangatho:Iimaski ze-solder zanamhlanje zihambelana ngokuqhelekileyo ne-ROHS (Ukuthintelwa kokuSetyenziswa kweeNgcaciso ezithile ezinobungozi) kunye neminye imigangatho yokusingqongileyo, inceda ukunciphisa impembelelo yenkunkuma ye-elektroniki kwindalo kunye nokuhlangabezana neemfuno zemarike yamazwe ngamazwe.
8. Lungiselela ukusebenza kokutshabalalisa ubushushu:Nangona oku kungengomsebenzi othe ngqo wemaski ye-solder, ngoyilo olufanelekileyo, olufana nokuphepha okanye ukunciphisa iileya zemaski ze-solder kwiindawo ezibalulekileyo zokuchitha ubushushu, ukusebenza kokushisa ubushushu beePCB kunokuphuculwa.
Ke ngoko, imaski ye-solder efanelekileyo kunye nekumgangatho ophezulu inokuphucula kakhulu ukuthembeka kunye nobomi benkonzo yeePCB. Ukukhethwa ngokucokisekileyo kunye nokusetyenziswa kwemaski ye-solder kwindlela yokuyila kunye nemveliso yeebhodi zeesekethe yenye yemilinganiselo ephambili yokuqinisekisa ukusebenza okuzinzile kwexesha elide kwiibhodi zeesekethe.
Ngaba uyazi ukuba zeziphi iinketho PCB solder imaski?
Umaleko we-solder ohlaza
Imaski ye-solder eluhlaza ibisoloko ithandwa kakhulu kwi-PCB solder mask kuba ivumela yonke into ukuba ibonakale ngokucacileyo. Umaleko we-solder oluhlaza unomahluko olungileyo phakathi kweendawo ezinobhedu kunye nangaphandle kobhedu ngaphantsi kwe-solder mask layer. Ungawabona ngokulula amanqaku ngamehlo akho, kodwa kwimaski emnyama ye-solder - awazi.
Umaleko wemaski emhlophe
Ukusetyenziswa kwemaski emhlophe ye-solder kuya kuthandwa kakhulu kuba umhlophe unokwenza ii-PCB zibukeke zintle kakhulu kwindawo ecocekileyo. Nangona kunjalo, umaleko we-mask solder omhlophe ufihla ngokufanelekileyo umkhondo. Kwezinye iimeko, uhlolo olubonakalayo alunakwenzeka, ngakumbi ukuba ukwigumbi elinokukhanya okuphezulu kuphela.
Umaleko we-mask solder emnyama
Xa kuthelekiswa nokhetho olumhlophe, umaleko wemaski omnyama we-solder unika ii-PCBs isiphelo esiphezulu kunye nenkangeleko yobuchwephesha, ebonelela ngokubonakalayo ixabiso elinamandla lobuchwephesha kunye nobuhle kwiimveliso, ezilungele kakhulu iimveliso zombane zabathengi ezineemfuno zembonakalo ephezulu.
Kuyafaneleka ukuba uqaphele ukuba umaleko we-black solder mask nawo ubeka imingeni ethile. Ngenxa yokufunxa ukukhanya okuphezulu, iiPCB ezimnyama zinokuthi zithande ukufunxa ubushushu ngexesha lenkqubo yokuvelisa, nto leyo enokukhokelela kuxinzelelo lobushushu kwiimeko ezithile kwaye ifune ulawulo ngexesha loyilo kunye nenkqubo yokuvelisa. Ukongeza, umaleko we-mask we-solder emnyama unamandla amakhulu okufihla iziphene zangaphakathi kwii-PCB, ngoko ke imigangatho ephezulu kunye nemilinganiselo engqongqo yokulawula umgangatho kufuneka yamkelwe kwiinkqubo zemveliso kunye nokuhlola.
Umaleko we-mask solder obomvu
Ukukhetha umaleko we-solder ebomvu kufuna ukuqwalaselwa kwezinye izinto. Umaleko we-mask obomvu we-solder unokubonakalisa ngokuthe ngqo iinkcukacha zamanqaku e-welding kunye neesekethe, okwenza kube lula ukuchonga iingxaki ekuhlolweni kwemveliso kunye nokugcinwa kamva. Imibala yayo eqaqambileyo ikwanceda ekuphuculeni izinga lokubona impazamo kwiinkqubo zokuhlolwa kwe-optical (AOI). Ngokomzekelo, xa kuthelekiswa nemigangatho yemaski emnyama (efana nomnyama kunye nohlaza), obomvu unokuba namandla kancinane okufihla iziphene zangaphakathi kwezinye iimeko, ezinokuthi zibe nempembelelo ethile kwimbonakalo yobuhle beebhodi zesekethe. Ngexesha elifanayo, kwiindawo ezithile zesicelo, abasebenzisi nabo kufuneka baqwalasele izinto ezifana nokuzinza komzimba kunye neekhemikhali zemaski ye-solder.
Umaleko wemaski eblue solder
Ibhodi yesekethe eneelebhile ezinzima kufuneka icinge ngokusebenzisa i-blue solder mask layer, njengoko yenza ukuchasana okucacileyo kunye nokuprintwa kwesikrini. Ukuba akukho sibane sifanelekileyo kunye nokwandiswa, amanqaku aphantsi kwe-solder imaski eluhlaza kuya kuba nzima ngakumbi ukuwabona. Xa kuthelekiswa neminye imibala, ithanda kakhulu ukungcola.
Umaleko wemaski wesolder omfusa
Imibala emininzi emitsha iyavela, kodwa kunokuba nzima ukuyilawula. Ngamanye amaxesha, iibhetshi ezahlukeneyo zemveliso zinokubonisa umahluko ofihlakeleyo. Umthubi kunye neorenji yimibala emnandi, kodwa umahluko wabo ekushicileleni isikrini kunye nomkhondo ufana nedama. Umaleko we-solder ongwevu uthathwa njengesiqhelo kwiibhodi zesekethe eziprintiweyo ze-LED / iiprojekthi ze-PCB ze-aluminium.
Umaleko wemaski we-Crystal ocacileyo wombala we-solder
Imibala eyahlukeneyo iya kulungelelanisa iimfuno ezahlukeneyo, njengokucoceka, ukubonakala, kunye nesimbo. Phambi kokuba uqale ukuveliswa ngobuninzi bemibala emitsha, unokuhlala uzama iisampuli kunye nathi.
Phambi kokuzama uyilo olulandelayo lwePCB, siyakwamkela ngokufudumeleyo ukuba uqhagamshelane nabasebenzi bethu abathengisayo ukuze ufumane iisampulu zasimahla - ungazisebenzisa njengereferensi. Ababoneleli bethu abaphambili be-inki yemaski ye-solder baquka iTaiyo Japan, iTaiyo USA, kunye neTaiyo Suzhou.
