Ngabavelisi bendibano yePCB baqinisekisa njani umgangatho wePCB?

Njengoko iteknoloji iqhubela phambili, iibhodi zesekethe eziprintiweyo (PCBs) ziye zaba yinxalenye ebalulekileyo yezixhobo ezininzi zombane. Ukusuka kwii-smartphones ukuya kwizixhobo zonyango, iiPCB zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokufanelekileyo kwezi zixhobo. Ngoko ke, abavelisi bendibano yePCB kufuneka balandele uvavanyo olungqongqo kunye neenkqubo zokuhlola ukuqinisekisa umgangatho weemveliso zabo.Kule post yebhlog, siza kuphonononga amanyathelo ahlukeneyo kunye nemilinganiselo ethathwa ngaba bavelisi ukuqinisekisa iiPCB ezikumgangatho ophezulu.

Uhlolo oluBonakalayo lokuqala:

Inyathelo lokuqala kwinkqubo yolawulo lomgangatho luhlolo olubonakalayo lwePCB. Abavelisi bendibano yePCB bahlole ngononophelo iibhodi zesekethe kuzo naziphi na iziphene zomzimba ezifana nemikrwelo, izibonda, okanye izinto ezonakeleyo. Olu hlolo lokuqala lunceda ukuchonga nayiphi na imiba ebonakalayo enokuchaphazela ukusebenza kwePCB okanye ukuthembeka.

uvavanyo lomsebenzi:

Emva kokuba ukuhlolwa kokuqala kugqityiwe, umenzi uqhubela phambili kuvavanyo olusebenzayo. Eli nyathelo libandakanya ukuvavanya ukusebenza kombane kwe-PCB ngokwenza iimvavanyo ezahlukeneyo kwi-PCB. Ezi mvavanyo ziqinisekisa ukuba i-PCB isebenza ngokulindelekileyo kwaye ihlangabezana neenkcukacha ezifunekayo. Uvavanyo olusebenzayo lunokubandakanya iimvavanyo ezinjengokuvavanya amandla, ukufikelela kwindawo yovavanyo, uhlalutyo lwentembeko yomqondiso, kunye novavanyo lomda wokuskena.

UHlolo oluSebenzayo lwaMacho (AOI):

Ukuqinisekisa umgangatho kunye nokuchaneka kweendibano zePCB, abavelisi bahlala besebenzisa iisistim ze-automated optical inspection (AOI). I-AOI isebenzisa iikhamera ezinesisombululo esiphezulu ukuthwebula imifanekiso yeePCB ezidityanisiweyo. Isoftware eqhutywa yi-AI emva koko ithelekisa le mifanekiso kuyilo lwereferensi, ukuchonga nakuphi na ukungangqinelani njengamacandelo angekhoyo, ukungahambi kakuhle okanye iziphene ze-soldering. I-AOI iphucula ngokumangalisayo ukuchaneka kunye nesantya sokuhlola, kwaye inokubona nezona ziphene zincinci ezinokuphoswa kuhlolo lwezandla.

Ukuhlolwa kweX-reyi:

KwiiPCB ezintsonkothileyo ezinamacandelo afihlakeleyo okanye angabonakaliyo, uhlolo lwe-x-reyi lunokuba luncedo. Ukuhlolwa kwe-X-reyi kuvumela abavelisi ukuba babone ngaphaya kweemaleko zePCB kwaye bakhangele naziphi na iziphene ezinokuthi zibe khona, ezifana neebhulorho ze-solder okanye i-voids. Le ndlela yokuvavanya engonakalisiyo inceda ukuchonga imiba engenakubonwa ngokuhlolwa okubonakalayo okanye i-AOI, iqinisekisa imfezeko yesakhiwo kunye nokusebenza kwe-PCB.

Uvavanyo lwe-Intanethi (ICT):

Uvavanyo lwe-in-circuit (ICT) lelinye inyathelo elibalulekileyo kwinkqubo yokulawula umgangatho. Ngexesha lenkqubo ye-ICT, abavelisi basebenzisa izixhobo ezikhethekileyo ukuvavanya ukusebenza kwamacandelo kunye neesekethe kwi-PCB. Ngokusebenzisa i-voltages ethile kunye neempawu, umvavanyi unokubona nayiphi na into engaphumeleli, isiphaluka esifutshane okanye isiphaluka esivulekileyo. I-ICT inceda ekuchongeni amalungu angalunganga okanye imidibaniso enokubangela ukuba iPCB isilele okanye isebenze kangangoko.

Uvavanyo lokuguga:

Ukuvavanya ukuthembeka kwexesha elide kunye nokuzinza kwee-PCBs, abavelisi bahlala besenza iimvavanyo zokutshisa kuzo. Uvavanyo lokutshisa lubandakanya ukuveza i-PCB kumaqondo obushushu aphezulu (ngokuqhelekileyo ngaphezu koluhlu lwayo lokusebenza) ixesha elide. Olu vavanyo lungqongqo lunceda ukuchonga naziphi na iimpazamo okanye ubuthathaka kwicandelo kwaye iqinisekisa ukuba iPCB inokumelana neemeko zokusebenza eziqhelekileyo ngaphandle kokusilela.

Uvavanyo lokusingqongileyo:

Kuba ii-PCBs zinokuchatshazelwa ziimeko ezahlukeneyo zokusingqongileyo, kubalulekile ukuvavanya ukuqina kwazo kunye nokusebenza kwazo phantsi kweemeko ezahlukeneyo. Uvavanyo lokusingqongileyo lubandakanya ukuveza ii-PCB kubushushu obugqithisileyo, ukufuma, ukungcangcazela kunye nokothuka. Ezi mvavanyo zivavanya ukuxhathisa kwe-PCBs kwiimeko ezimbi kwaye ziqinisekisa ukuba ziyakwazi ukumelana neemfuno zezicelo zehlabathi lokwenene.

uvavanyo lokugqibela:

Phambi kokuba iiPCB zithunyelwe ngenqanawa kubathengi, ziye zihlolwe okokugqibela ukuze ziqinisekise ukuba ziyahlangabezana nazo zonke iimfuno ezikhankanyiweyo. Olu hlolo lubandakanya uhlolo olucokisekileyo lwenkangeleko yePCB, imilinganiselo, ukusebenza kombane kunye nokusebenza. Uhlolo lokugqibela olucokisekileyo lunciphisa amathuba okuba ii-PCBs ezineziphene zisiwe kubathengi, ngaloo ndlela kuqinisekisa eyona migangatho iphezulu yomgangatho.

Ukuqukumbela, abavelisi bendibano yePCB baqhuba uluhlu lweenkqubo zovavanyo kunye nokuhlola ukuqinisekisa umgangatho weemveliso zabo.Ukuhlolwa okubonakalayo, uvavanyo olusebenzayo, i-AOI, ukuhlolwa kwe-X-ray, i-ICT, uvavanyo lokutshisa, uvavanyo lokusingqongileyo kunye nokuhlolwa kokugqibela konke kudlala indima ebalulekileyo kwinkqubo yokulawula umgangatho. Ngokulandela ngokungqongqo ezi nkqubo, abavelisi banokuqinisekisa ukuba ii-PCB abazivelisayo ziyahlangabezana nemigangatho efunekayo, ngaloo ndlela bebonelela abathengi ngeemveliso ezithembekileyo nezikumgangatho ophezulu.
