Uvavanyo olubonakalayo olwenziwa ngesandla kukuqinisekisa ukufakwa kwamacandelo kwiPCB ngeumbono womntu kunye nothelekiso, kwaye obu buchwepheshe yenye yezona ndlela zisetyenziswa kakhulu zovavanyo lwe-intanethi.Kodwa njengoko imveliso isanda kwaye iibhodi zeesekethe kunye namacandelo ayancipha, le ndlela iba ngaphantsi kwaye ingasebenzi.Iindleko eziphantsi zangaphambili kwaye akukho luvavanyo lokuvavanywa ziinzuzo zalo eziphambili;Ngexesha elifanayo, iindleko eziphezulu zexesha elide, ukufumanisa isiphene esingapheliyo, ubunzima bokuqokelela idatha, akukho vavanyo lombane kunye nokulinganiselwa okubonakalayo nazo ziyizinto ezingalunganga zale ndlela.
1, uHlolo oluSebenzayo lokuHlola (AOI)
Le ndlela yovavanyo, ekwabizwa ngokuba luvavanyo oluzenzekelayo lokujonga, idla ngokusetyenziswa ngaphambi nasemva kwe-reflux, kwaye yindlela entsha yokuqinisekisa iziphene zokuvelisa, kwaye inesiphumo esingcono sokukhangela kwi-polarity yamacandelo kunye nobukho bamacandelo.Yiteknoloji engeyiyo yombane, i-jig-free kwi-intanethi.Iinzuzo zayo eziphambili zilula ukulandela ukuxilongwa, kulula ukuphuhlisa inkqubo kwaye akukho ukulungiswa;Eyona nto ingathandekiyo kukungaqondwa kakuhle kweesekethe ezimfutshane kwaye ayilulo uvavanyo lombane.
2. Uvavanyo olusebenzayo
Uvavanyo olusebenzayo ngowona mgaqo wokuqala wovavanyo oluzenzekelayo, eyona ndlela yovavanyo olusisiseko lwendlela ethilePCBokanye iyunithi ethile, kwaye inokugqityezelwa ngezixhobo ezahlukeneyo zovavanyo.Kukho iintlobo ezimbini eziphambili zovavanyo olusebenzayo: Uvavanyo lokugqibela lweMveliso kunye ne-Hot Mock-up.
3. I-Flying-Probe Tester
Umatshini wokuvavanya inaliti ebhabhayo, okwaziwa ngokuba ngumatshini wovavanyo lokuhlola, ukwayindlela yovavanyo esetyenziswa ngokuqhelekileyo.Ngombulelo kwinkqubela phambili yokuchaneka koomatshini, isantya kunye nokuthembeka, ifumene ukuthandwa ngokubanzi kwiminyaka embalwa edlulileyo.Ukongezelela, imfuno yangoku yenkqubo yokuvavanya kunye nokuguqulwa ngokukhawuleza kunye nekhono le-jig-free elifunekayo kwi-Prototype yokuvelisa kunye nokuveliswa kwevolumu ephantsi kwenza uvavanyo lwenaliti ebhabhayo lube lolona khetho lungcono.Iingenelo eziphambili zomatshini wokuvavanya inaliti endizayo kukuba sesona sixhobo sikhawulezayo sokuya kwiNdawo yokuThengisa, ukuveliswa kovavanyo oluzenzekelayo, akukho ndleko yokulungisa, ukuxilongwa kakuhle kunye neprogram elula.
