Enqubweni yokukhiqiza ye-PCB, inqubo yokwelashwa engaphezulu yisinyathelo esibaluleke kakhulu. Akunandaba kuphela ukubukeka kwe-PCB, kepha futhi kuhlobene ngqo nokusebenza, ukuthembeka nokuqina kwe-PCB. Inqubo yokwelashwa engaphezulu inganikeza ungqimba lokuvikela ukuvikela ukuwohloka kwethusi, uthuthukise ukusebenza kwe-soldering, futhi unikeze izakhiwo ezinhle zokufakelwa kukagesi. Okulandelayo ukuhlaziywa kwezinqubo eziningana zokwelashwa ezijwayelekile ekukhiqizeni i-PCB.
一 .hasl (umoya oshisayo)
Ukuhanjiswa komoya okushisayo (i-hasl) ubuchwepheshe be-PCB be-PCB engaphezulu kwe-PCB esebenza ngokufaka i-PCB ku-tin ye-tin / lead exten bese usebenzisa umoya oshisayo ukuze udale umhlanga wensimbi. Inqubo ye-hasl ibiza kakhulu futhi ilungele ukukhiqiza okuhlukahlukene kwe-PCB, kepha ingahle ibe nezinkinga ngamaphabhu angalingani kanye nokuqina kwensimbi okungahambelani.
二 .enig (amakhemikhali amakhemikhali)
I-Electroel Pickel Gold (Enig) iyinqubo ebeka i-nickel ne-learl ungqimba ngaphezulu kwe-PCB. Okokuqala, indawo yethusi iyahlanzwa futhi yasebenza, bese ungqimba oluncanyana lwe-nickel lufakwa ekuphendukelweni kabusha kwamakhemikhali, bese ekugcineni ungqimba lwegolide lugcwele ngaphezulu kwesendlalelo se-nickel. Inqubo ye-Enig ihlinzeka ngokumelana kahle nokungamelana nalokhu futhi i-Wear Resignance futhi ilungele izinhlelo zokusebenza ezinezidingo eziphezulu eziphezulu, kepha izindleko ziphakeme kakhulu.
三, igolide lamakhemikhali
Igolide lamakhemikhali lifaka ungqimba oluncane lwegolide ngqo kwi-PCB engaphezulu. Le nqubo ivame ukusetshenziswa kuzinhlelo zokusebenza ezingadingi ukuthengisa, njengemvamisa yeRadio (Rf) kanye ne-Microwave Circuits, ngoba igolide lihlinzeka ngokuvuselelwa okuhle nokuqina. Igolide lamakhemikhali libiza okungaphansi kwe-enig, kepha aligqokile njengo -nig.
四, i-osp (ifilimu evikela i-organic)
Ifilimu elivikelayo le-organic (i-OSP) liyinqubo eyakha ifilimu elincanyana elenziwa yi-organic phezulu yethusi ukuvikela ithusi kusuka ku-oxidizing. I-OSP inenqubo elula nezindleko eziphansi, kepha ukuvikelwa okuhlinzeka kubuthakathaka futhi kufanelekile ukugcina isikhathi esifushane nokusetshenziswa kwama-PCB.
五, igolide eliqinile
I-Hard Gold yinqubo ebeka ungqimba olubanzi lwegolide ku-PCB ebusweni ngokusebenzisa i-electroplating. Igolide elinzima liyavimbela ukwedlula igolide lamakhemikhali futhi lilungele izixhumi ezidinga ukuxhumeka njalo kanye noma ama-PCB asetshenziswa ezindaweni ezinokhahlo. Izindleko zegolide ezinzima ngaphezu kwegolide lamakhemikhali kodwa zinikeza ukuvikela okungcono kwesikhathi eside.
六, isiliva lokucwilisa
Isiliva sokucwilisa yinqubo yokufaka isendlalelo sesiliva ngaphezulu kwe-PCB. Isiliva linokuvuka okuhle nokuvezwa, okwenza kube lulungele izinhlelo zokusebenza ezibonakalayo nezingezinhle. Izindleko zenqubo yesiliva yokucwilisa zilinganiselwe, kepha ungqimba wesiliva ubuvuselelwa kalula futhi kudinga izindlela ezengeziwe zokuvikela.
七, i-tin yesibeletho
I-tin yokucwilisa inqubo yokufaka ungqimba lwe-tin phezu kwePCB. Isendlalelo se-tin ihlinzeka ngezakhiwo ezinhle zokuthengisa kanye nokuphikiswa kokugqwala. Inqubo yokucwilisa eshibhile, kepha isendlalelo se-tin sisebenza kalula futhi sivame ukudinga ungqimba olwengeziwe wokuvikela.
八, i-hadl ehambisanayo ye-hadl
I-Healing-free Halll inqubo ye-hasl evumelana ne-ROHS esebenzisa i-tin-free tin / sesiliva / yethusi i-alloy ukuze ifake i-tin yendabuko yendabuko / ukuhola. Inqubo ye-hall yamahhala ye-lead-free ihlinzeka ngokusebenza okufanayo kwe-hasl yendabuko kepha ihlangabezana nezidingo zemvelo.
Kunezinqubo ezahlukahlukene zokwelashwa komhlaba ekukhiqizeni i-PCB, futhi inqubo ngayinye inezinzuzo zayo ezihlukile nezimo zohlelo lokusebenza. Ukukhetha inqubo efanele yokwelashwa komhlaba kudinga ukucubungula imvelo yohlelo lokusebenza, izidingo zokusebenza, isabelomali sezindleko kanye namazinga okuvikela ezemvelo we-PCB. Ngokuthuthukiswa kobuchwepheshe be-elekthronikhi, izinqubo ezintsha zokwelashwa komhlaba ziyaqhubeka nokuphuma, ukuhlinzeka abakhiqizi be-PCB ngezinketho eziningi zokuhlangabezana nezidingo zemakethe.
