Uvavanyo kunye neenkqubo zokulawula umgangatho zidlala indima ebalulekileyo ekuchongeni nasekulungiseni nayiphi na imiba enokubakho ngaphambi kokuba ezi zijikelezo eziguquguqukayo zihlanganiswe kwimveliso yokugqibela. Kule post blog, siza kuxubusha ezinye iindlela ezisebenzayo zokuvavanya kunye nokulawulwa komgangatho weebhodi zeesekethe eziguquguqukayo.
Iibhodi zesekethe eziguquguqukayo, ezaziwa ngokuba ziiPCB eziguquguqukayo, ziye zafumana ukuthandwa ngokubanzi kushishino lwe-elektroniki ngenxa yokuguquguquka kwazo kunye nokukwazi ukuziqhelanisa neemilo kunye nobukhulu obahlukeneyo. Ezi zijikelezo eziguquguqukayo zisetyenziswa kwiinkqubo ezahlukeneyo ezibandakanya i-aerospace, i-automotive, i-electronics yabathengi, izixhobo zonyango, kunye nokunye. Nangona kunjalo, ukuqinisekisa umgangatho kunye nokuthembeka kwezi bhodi zeesekethe eziguquguqukayo kubalulekile ekuphunyezweni kwazo ngempumelelo.
1. Ukuhlolwa okubonakalayo:
Isinyathelo sokuqala kwinkqubo yokulawula umgangatho kukuhlola okubonakalayo. Umsebenzisi oqeqeshiweyo kufuneka ahlole ngocoselelo ibhodi yesekethe nganye ebhetyebhetye ukuze abone naziphi na iziphene ezibonakalayo okanye ezingaqhelekanga. Oku kubandakanya amacandelo okuhlola ukungahambi kakuhle, iziphene ze-welding, imikrwelo, i-delamination, okanye nawuphi na omnye umonakalo obonakalayo. Iikhamera zesisombululo esiphezulu kunye nesofthiwe ye-imaging ephezulu iyafumaneka ukuphucula ukuchaneka kunye nokuthembeka kokuhlolwa okubonakalayo.
2. Ubungakanani bovavanyo:
Uvavanyo lwe-Dimensional luqinisekisa ukuba iibhodi zeesekethe eziguquguqukayo zihlangabezana neenkcukacha ezifunekayo kunye nemida yokunyamezela. Oku kubandakanya ukusebenzisa izixhobo zokulinganisa ezichanekileyo ukulinganisa ubukhulu, ububanzi, kunye nobude besekethe ye-flex. Kubalulekile ukuqinisekisa ukuba le milinganiselo iphakathi koluhlu oluchazwe kwangaphambili ukuphepha nayiphi na imiba enokubakho ngexesha lokudibanisa okanye ukudibanisa.
3. Uvavanyo lombane:
Uvavanyo lombane lubalulekile ukuvavanya ukusebenza kunye nokusebenza kweebhodi zeesekethe eziguquguqukayo. Le nkqubo ibandakanya ukujonga iiparamitha ezahlukeneyo zombane ezifana nokuchasana, amandla, impedance, kunye nokuqhubeka. Izixhobo zovavanyo oluzenzekelayo (ATE) zingasetyenziselwa ukulinganisa ngokuchanekileyo nangokufanelekileyo kunye nokuhlalutya ezi mpawu zombane.
4. Uvavanyo lokuguquguquka:
Ekubeni inzuzo ephambili yeebhodi zeesekethe eziguquguqukayo kukuguquguquka kwazo, kuyimfuneko ukuvavanya amandla abo okumelana nokugoba, ukujija okanye nayiphi na enye ingcinezelo yomatshini. Abavavanyi be-bend abakhethekileyo bangasetyenziselwa ukulinganisa ukunyakaza okugoba okuhlukeneyo kunye nokumisela ukuguquguquka kwesekethe, ukuqinisekisa ukuba inokumelana neemeko zokusingqongileyo zesicelo esicetywayo.
5. Uvavanyo lokusingqongileyo:
Uvavanyo lokusingqongileyo lubandakanya ukubeka iibhodi zeesekethe eziguquguqukayo kwiimeko ezinzima ukuvavanya ukuqina kwazo kunye nokuthembeka. Oku kunokubandakanya ukukhwela ibhayisekile, uvavanyo lokufuma, ukothuka kobushushu, okanye ukuba sesichengeni kwimichiza. Ngokuhlalutya indlela isiphaluka esiguquguqukayo esenza ngayo phantsi kwezi meko zinzima, abavelisi banokuqinisekisa ukuba kufanelekile kwisicelo esithile.
6. Uvavanyo lokuthembeka:
Uvavanyo lokuthembeka lwenzelwe ukuvavanya ixesha elide kunye nokuzinza kweebhodi zeesekethe eziguquguqukayo. Uvavanyo olukhawulezileyo lobomi lunokwenziwa ukulinganisa inkqubo yokuguga ngokubeka iisekethe kwiimeko zoxinzelelo olukhawulezileyo ixesha elide. Oku kunceda ukuchonga ubuthathaka obunokwenzeka kwaye kwenza ukuba abavelisi baphucule uyilo okanye izinto ezisetyenziswa kwinkqubo yokuvelisa.
7. Ukuhlolwa kweX-reyi:
Ukuhlolwa kwe-X-ray yindlela yokuvavanya engonakalisi evumela uhlalutyo olunzulu lwesakhiwo sangaphakathi seebhodi zeesekethe eziguquguqukayo. Iyakwazi ukubona iziphene ezifihliweyo ezifana nokuqhekeka, i-voids okanye i-delamination enokuthi ingabonakali ngokuhlola okubonakalayo. Ukuhlolwa kwe-X-ray kuluncedo ngokukhethekileyo ekuchongeni iingxaki ezinokuthi zibe khona kwi-solder joints okanye ukuqinisekisa ukuba amacandelo ahambelana ngokufanelekileyo.
Isishwankathelo
Ukuqhuba uvavanyo olucokisekileyo kunye nenkqubo yokulawula umgangatho kubalulekile ekuqinisekiseni ukuthembeka, ukusebenza, kunye nexesha elide leebhodi zeesekethe eziguquguqukayo. Ngokudibanisa ukuhlolwa okubonakalayo, uvavanyo lwe-dimensional, uvavanyo lombane, uvavanyo lokuguquguquka, ukuvavanywa kokusingqongileyo, uvavanyo lokuthembeka kunye nokuhlolwa kwe-X-ray, abavelisi banokunciphisa kakhulu ingozi ehambelana nezi zijikelezo eziguquguqukayo. Ngokuthobela ezi nkqubo zokulawula umgangatho, abavelisi banokubonelela abathengi ngeebhodi zeesekethe ezithembekileyo kunye neziphezulu eziguquguqukayo ezifanelekileyo kwiinkqubo ezahlukeneyo.
