Luluphi uvavanyo olothusayo lwe-pcba?

Inkcazo

I-Infrared PCBA (i-PCRBARD COLCIP STOCIS) Uvavanyo lwe-Thermal Olwo luvavanyo lokuthembeka. Kusetyenziswa ikakhulu ukuvavanya ukunyamezelana kwe-PCB kwindalo yokutshintsha ngokukhawuleza.

Injongo yokuvavanya

Jonga ukuthembeka okujongelayo kwiTshino: Kwinkqubo yokwenziwa kwemveliso yePCB, amalungu othumelwano uqokelele amacandelo ahlukeneyo e-elektroniki kwaye aprintiweyo. Uloyiko lwe-thermal lunokubangela ukuba umthengisi ujoyine ukuba usandiswe kunye neenkqubo zokuphatha. Ngovavanyo lothusayo lwe-shirmal, kunokwenzeka ukuba ubone ukuba ngaba i-jornent iyasebenza, iya kuqhekeza, ikhulule kunye nezinye iingxaki phantsi kotshintsho olubukhali. Umzekelo, kwi-PCBA yabathengi abathengi, njengeyona fowuni yefowuni, ukuba umgangatho wejoni odibeneyo awukaphumi, isiphaluka sinokwaphuka emva kothuso lwefowuni .

UVAVANYO UTSHINTSHO OLUFANELEKILEYO LWEENDLELA: Ukusebenza kwezixhobo ze-elektroniki kunokuchaphazeleka xa iqondo lobushushu litshintsha. Umzekelo, ixabiso lokuxhobisa le-capacitor linokutshintsha ngotshintsho olubukhali kubushushu. Uvavanyo lokukhohlakala olunokunceda ukuba la macandelo asebenza ngokufanelekileyo phantsi kweqondo lobushushu lokutshintsha imeko yokutshintsha kwaye ukuba umahluko wentsebenzo ungaphakathi kwemida evumelekileyo.

Jonga ubume bezinto ezibonakalayo: kunye nokuphumelela. Uvavanyo lokutyibilika nge-thermal lunokukhangela ulungelelwaniso phakathi kwezi zixhobo.

Inkqubo yovavanyo

Iimfuneko zezixhobo: igumbi lokuhlola i-shirt liqhele ukusetyenziswa kuvavanyo. Igumbi lokuvavanya linokutshintshela ngokukhawuleza phakathi kwamaqondo aphezulu kwaye aphantsi akwazi ukulawula ngokuchanekileyo inqanaba kunye noluhlu lotshintsho lobushushu.

Ukucwangciswa kweparamitha yovavanyo: kubandakanya ukubeka ixabiso eliphezulu lobushushu, ixabiso lobushushu esisezantsi kunye nenani lemijikelezo yokutshintsha kobushushu. Ngokubanzi, ubushushu obuphezulu bunokusetwa malunga ne-125 ° C, kwaye iqondo lobushushu elisezantsi linokusetwa malunga ne-40 ° C. Inani lemijikelezo linokusetwa kwi-cycles okanye amatye amaxesha okusebenza kunye neemfuno ze imveliso. Ixesha lomjikelo ngamnye nalo kufuneka libekwe ngokufanelekileyo, njengexesha lokuphumla phakathi kobushushu obuphakathi ukuya kubushushu obuphantsi kwaye babuyela kubushushu obuphezulu.

Ukuvavanywa kwesampulu yesampula: Isampulu yePCBA ibekwe kwindawo echaziweyo kwigumbi lokuhlola i-shirt ukuqinisekisa ukuba inokuchaphazeleka ngokupheleleyo kukutshintsha kobushushu kwaye kuthintele ukuphazamiseka phakathi kweesampulu.

Uvandlakanyo lweziphumo zovavanyo

Uvavanyo olubonakalayo: Emva kovavanyo lokutyibilika kwe-thermal, uvavanyo lwe-PCBA lwenziwe kuqala. Jonga umonakalo ocacileyo onjengeSoftware Shumition, iThuthi yeThuqu iwe

Uvavanyo lokuSebenza koMbane: Sebenzisa izixhobo zovavanyo zovavanyo, ezinjenge-Multater, i-Oscillocope, njl. Njl. Jonga ukuba isekethe ihlala iqhutywa, kwaye nokuba iiparamitha zombane zecandelo ngalinye zisekuluhlu olufanelekileyo. Umzekelo, nokuba umgca wokuhambisa amandla usenokuqhubeka ebonelelwa, nokuba kukho ukugqwetha komqondiso kumgca wokuhambisa umqondiso, njalo njalo.

Kwigama, uvavanyo lwe-PCBA lwe-PCBA lobume be-shock lubaluleke kakhulu ekuqinisekiseni umgangatho kunye nokuthembeka kweemveliso ze-PCBA. Ngokulinganisa ubushushu obuqatha ngobushushu, iziphene ezinokubakho kuyilo lwemveliso, ukhetho lwezinto ezibonakalayo okanye inkqubo yokwenziwa okanye inkqubo yokwenziwa inokufunyanwa kwangaphambili, ukuze imveliso iphuculwe kwaye isebenze ngokusesikweni. Oku kunceda ukunciphisa izinga lokusilela kwemveliso kwiNkqubo yokuSetyenziswa, kuphucule uzinzo kunye nobomi benkonzo, kunye nokomeleza ukhuphiswano lwemveliso kwintengiso. Nokuba yintsimi yombane wabathengi, intsimi yolawulo lwemizi-mveliso okanye i-automa yolawulo lwemoto kunye nezinye iinkalo ze-PCBA zenye yezona ndlela zibalulekileyo ze-elektroniki zonke, ezibeka isiseko esomeleleyo somsebenzi oqinileyo we Izixhobo ze-elektroniki.
