Lesi sihloko sikunikeza isingeniso esibanzi sezidingo zenqubo yokubhaka yebhodi lesifunda le-PCB kanye nezincomo zokonga amandla.Ngokukhula kwenhlekelele enkulu yamandla emhlabeni wonke kanye nokuqiniswa kwemithetho yezemvelo, abakhiqizi be-PCB babeke phambili izidingo eziphakeme zezinga lokonga amandla lezinto zokusebenza.Ukubhaka kuyinqubo ebalulekile ohlelweni lokukhiqiza lwe-PCB.Izicelo ezivamile zisebenzisa amanani amakhulu kagesi.Ngakho-ke, ukuthuthukisa imishini yokubhaka ukuze kuthuthukiswe ukongiwa kwamandla sekuphenduke enye yezindlela zabakhiqizi bebhodi le-PCB ukonga amandla nokunciphisa izindleko.
Inqubo yokubhaka icishe idlule kuyo yonke inqubo yokukhiqizwa kwebhodi lesifunda le-PCB.Okulandelayo kuzokwethula izidingo zenqubo yokubhaka zokukhiqizwa kwebhodi lesifunda le-PCB.
1. Izinyathelo zenqubo ezidingekayo zokubhaka amabhodi e-PBC
1. Ukucwenga, ukuchayeka, kanye nokubansundu ekukhiqizeni amaphaneli ongqimba angaphakathi kudinga ukungena endaweni yokomisa ukuze kubhakwe.
2. Ukuqondisa, ukuhlunga nokugaya ngemva kokulahlwa kuyadingeka ukususa umswakama, i-solvent kanye nokucindezeleka kwangaphakathi, ukuzinzisa isakhiwo nokuthuthukisa ukunamathela, futhi kudinga ukwelashwa kokubhaka.
3. Ithusi eliyinhloko ngemva kokumba idinga ukubhaka ukuze kuthuthukiswe ukuzinza kwenqubo ye-electroplating.
4. Ukwelashwa kwangaphambili, i-lamination, ukuchayeka kanye nokuthuthukiswa ekukhiqizeni ungqimba lwangaphandle konke kudinga ukushisa kokubhaka ukushayela ukusabela kwamakhemikhali ukuze kuthuthukiswe ukusebenza kwempahla kanye nemiphumela yokucubungula.
5. Ukuphrinta, ukubhaka ngaphambilini, ukuchayeka, kanye nokuthuthukiswa ngaphambi kokuba imaski ye-solder idinga ukubhaka ukuze kuqinisekiswe ukuzinza nokunamathela kwempahla ye-solder mask.
6. Ukukhetha nokuphrinta ngaphambi kokuphrinta umbhalo kudinga ukubhaka ukukhuthaza ukusabela kwamakhemikhali nokuzinza kwezinto.
7. Ukubhaka ngemva kokwelashwa okungaphezulu kwe-OSP kubalulekile ekuzinzeni nasekubambeleleni kwezinto ze-OSP.
8. Kumele kubhakwe ngaphambi kokubunjwa ukuze kuqinisekiswe ukoma kwempahla, ukuthuthukisa ukunamathela nezinye izinto, nokuqinisekisa umphumela wokubumba.
9. Ngaphambi kokuhlolwa kwe-flying probe, ukuze ugweme amaphuzu angamanga kanye nezahlulelo ezingalungile ezibangelwa ithonya lomswakama, ukucubungula ukubhaka kuyadingeka.
10. Ukwelashwa kokubhaka ngaphambi kokuhlolwa kwe-FQC ukuvimbela umswakama ongaphezulu noma ngaphakathi kwebhodi le-PCB ekwenzeni imiphumela yokuhlolwa inganembile.
2. Inqubo yokubhaka ngokuvamile ihlukaniswe izigaba ezimbili: ukubhaka okunezinga lokushisa eliphezulu nokubhaka okunezinga lokushisa eliphansi:
1. Izinga lokushisa eliphezulu lokubhaka ngokuvamile lilawulwa cishe ku-110°C, futhi ubude besikhathi cishe amahora angu-1.5-4;
2. Izinga lokushisa eliphansi lokubhaka ngokuvamile lilawulwa cishe ku-70°C, futhi ubude besikhathi buyisikhathi esingamahora angu-3-16.
3. Ngesikhathi senqubo yokubhaka yebhodi lesifunda le-PCB, le mishini elandelayo yokubhaka nokomisa idinga ukusetshenziswa:
Ihhavini yomhubhe emile, ewonga amandla, ulayini wokukhiqiza wokubhaka ozenzakalelayo ozenzakalelayo, uhhavini we-infrared tonnel kanye nezinye izinto eziphrintiwe zebhodi lebhodi lebhodi le-PCB.
Izinhlobo ezahlukene zemishini kahhavini ye-PCB zisetshenziselwa izidingo ezihlukene zokubhaka, njengokuthi: I-PCB board hole plugging, ukubhaka kwesikrini semaski ye-solder, okudinga ukusebenza okuzenzakalelayo kwevolumu enkulu.Ohovini bomhubhe owonga amandla bavame ukusetshenziselwa ukonga inqwaba yabasebenzi kanye nezinsizakusebenza ngenkathi kufezwa ukusebenza kahle okuphezulu.Ukusebenza kahle kokubhaka, ukusebenza kahle kokushisa okuphezulu kanye nezinga lokusebenzisa amandla, ukonga kanye nemvelo, lisetshenziswa kabanzi embonini yebhodi lesifunda ukubhaka imaski ye-solder kanye nokubhaka okuthunyelwe kwamabhodi e-PCB;okwesibili, isetshenziselwa kakhulu ukubhaka nokomisa umswakama webhodi le-PCB nokucindezeleka kwangaphakathi.Kuyihhavini yokuhambisa komoya oshisayo eqondile enezindleko eziphansi zemishini, izinyawo ezincane futhi ifanele ukubhaka okuvumelana nezingqimba eziningi.
4. Izixazululo zokubhaka zebhodi lesifunda le-PCB, izincomo zemishini kahhavini:
Ukufingqa, kuwumkhuba ongenakugwenywa ukuthi abakhiqizi bebhodi lesifunda le-PCB banezidingo eziphakeme neziphakeme zamazinga okonga amandla wemishini.Kuyisiqondiso esibaluleke kakhulu sokuthuthukisa amazinga okonga amandla, ukonga izindleko kanye nokuthuthukisa ukusebenza kahle kokukhiqiza ngokuthuthukisa noma ukufaka esikhundleni semishini yenqubo yokubhaka.Ohovini bomhubhe owonga amandla anezinzuzo zokonga amandla, ukuvikelwa kwemvelo, nokusebenza kahle okuphezulu, futhi njengamanje asetshenziswa kabanzi.Okwesibili, amahhavini omoya oshisayo anezinzuzo eziyingqayizivele kumabhodi e-PCB aphezulu adinga ukubhaka okunembayo nokuhlanzeka okufana namabhodi e-IC carrier.Ngaphezu kwalokho, banemisebe ye-infrared.Iziko lomhubhe nezinye izinto zokusebenza zikahhavini ziyizixazululo zokomisa ezivuthiwe kanye nezixazululo.
Njengomholi kwezokongiwa kwamandla, i-Xinjinhui iqhubeka nokusungula izinto ezintsha futhi yenza izinguquko ngendlela efanele.Ngo-2013, inkampani yethula i-PCB yesizukulwane sokuqala sombhalo we-PCB owuhlobo lwesikrini sokuphrinta kuhhavini kahhavini, othuthukise ukusebenza okonga amandla ngo-20% uma kuqhathaniswa nemishini yendabuko.Ngo-2018, inkampani yaphinde yethula uhhavini wesizukulwane sesibili we-PCB wombhalo wokubhaka ngemuva kokubhaka, ozuze ukuthuthukiswa kwe-leapfrog ngama-35% ekongeni amandla uma kuqhathaniswa nesizukulwane sokuqala.Ngo-2023, ngocwaningo oluyimpumelelo nokuthuthukiswa kwenani lamalungelo obunikazi bokusungulwa kanye nobuchwepheshe obusha, izinga lokonga amandla lenkampani lenyuke lafika ku-55% uma liqhathaniswa nesizukulwane sokuqala, futhi selithandwe yizinkampani eziningi eziphezulu eziyi-100 ku-PCB. imboni, okuhlanganisa i-Jingwang Electronics.Lezi zinkampani zimenywe ngu-Xin Jinhui ukuthi zivakashele futhi zixhumane namaphaneli okuhlola efekthri.Ngokuzayo, i-Xinjinhui izophinde yethule imishini yobuchwepheshe obuphezulu.Sicela uhlale ubukele, futhi wamukelekile futhi ukusishayela ucingo ukuze nibonisane futhi wenze isikhathi sokusivakashela ukuze nixhumane ubuso nobuso.
