Yikuphi ukuhlolwa okushaqisayo kwe-PCBA?

Isichasiso

I-PCBA E-Infrared PCBA (Ephrintiwe IBHODI EBHODI EBHODI) Ukuhlolwa Okushaqisayo Ukuhlolwa Okuthembekile. Isetshenziselwa ikakhulukazi ukuhlola ukubekezelela kwe-PCB emvelweni esheshayo yokushisa yokushisa.

Inhloso yokuhlola

Hlola ukuthembeka okuhlangene okuhlangene: Ehlelweni lokukhiqiza le-PCB, amalunga we-soler axhumeka amabhodi ahlukahlukene we-elekthronikhi namabhodi wesifunda aphrintiwe. Ukushaqeka okushisayo kungadala ukuthi i-soler sihlanganiswe ukuba ikhishwe izinqubo nezinqubo zokulwa. Ngokuhlolwa okushaqisayo okushisayo, kungenzeka ukubona ukuthi ngabe i-solder ehlanganisiwe izokwehla, ukukhulula nezinye izinkinga ngaphansi koshintsho olubukhali lokushisa. Isibonelo, e-PCBA yemikhiqizo ethile yabathengi, efana nekhwalithi yefoni ephathekayo, uma ikhwalithi ye-solerge ye-sole akwamukeleki, umjikelezo ungaphulwa ngemuva kokushaqeka okushisayo, okuholela ekwehlulekeni kweminye imisebenzi yefoni ephathekayo .

Hlaziya izinguquko zokusebenza kwezonto: ukusebenza kwezinto ze-elekthronikhi kungathinteka lapho izinga lokushisa lishintsha. Isibonelo, inani le-capacitance le-capacitor lingashintsha ngoshintsho olubukhali lokushisa. Ukuhlolwa okushaqisayo okushisayo kungasiza ekuboneni ukuthi ngabe lezi zingxenye zingasebenza kahle ngaphansi kwezimo zokushisa zokushisa ngokweqile nokuthi ngabe ukuhlukahluka kokusebenza kungaphakathi kwemingcele evunyelwe.

Hlola ukuhambisana kwezinto ezibonakalayo: I-PCBA yakhiwa ngezinto ezahlukahlukene zokwakha, kufaka phakathi izinto zokwakha zesekethe ze-elekhronikhi, njll. Izinto ezihlukile zinezinkinga ezihlukile zokunwebeka, njengokuhleliwe nokuqhuma. Ukuhlolwa okushaqisayo kungabheka ukuhambisana phakathi kwalezi zinto zokwakha.

Inqubo yokuhlola

Izidingo zemishini: Igumbi lokuhlola elishisayo le-Thermal livame ukusetshenziselwa ukuhlola. I-Test Chamber ingashintsha ngokushesha phakathi kwamazinga okushisa aphezulu futhi aphansi, futhi ingalawula ngokunembile izinga nobubanzi bezinguquko zokushisa.

Ukuhlelwa kwepharamitha yepharamitha: kufaka phakathi ukusetha inani eliphakeme lokushisa, inani lokushisa eliphansi kanye nenombolo yemijikelezo yokushintsha lokushisa. Ngokuvamile, izinga lokushisa eliphakeme lingasetwa ku-125 ° C, futhi izinga lokushisa eliphansi lingasetwa cishe ku-40 ° C. Inani lemijikelezo lingasethelwa inqwaba noma ngisho namakhulu amahlandla ngokusho kwemvelo yokusebenzisa kanye nezidingo ze umkhiqizo. Isikhathi somjikelezo ngamunye sidinga ukusethwa ngendlela efanele, njengokuphumula kwesikhathi phakathi kokushisa okuphezulu kuya emazingeni aphansi bese ubuyela ekushiseni okuphezulu.

Ukubekwa kwesampula yokuhlola: Isampula ye-PCBA ibekwa esimweni esibekiwe egumbini lokuhlola elishisayo le-Thermal ukuqinisekisa ukuthi lingathinteka ngokugcwele izinguquko zokushisa futhi ligweme ukuphazamiseka phakathi kwamasampula.

Ukuhlolwa kwemiphumela yokuhlola

Ukuhlolwa okubukwayo: Ngemuva kokuphothulwa kokushaqeka kwe-thermal, ukuhlolwa okubukwayo kwe-PCBA kwenziwa kuqala. Funa ukulimala okusobala ngokomzimba okufana nokuthuthwa kwengxenye, okuhlangene okuhlangene okuwela, kanye nokuhleleka kwebhodi lesekethe.

Ukuhlolwa kokusebenza kukagesi: Sebenzisa imishini yokuhlola engochwepheshe, efana ne-multimeter, i-Oscilloscope, njll., Ukuhlola ukusebenza kukagesi kwe-PCBA. Bheka ukuthi umjikelezo ungaqhutshwa ngokujwayelekile, nokuthi amapharamitha kagesi engxenye ngayinye asaphakathi kobubanzi obufanele. Isibonelo, noma ngabe umugqa wokuhambisa amandla usengahlinzekwa ngokujwayelekile, noma ngabe kukhona ukuhlanekezela kwesiginali emugqeni wokuhambisa wesiginali, njalonjalo.

Kumagama, ukuhlolwa okushaqisayo kwe-PCBA kubaluleke kakhulu ukuqinisekisa ikhwalithi nokuthembela kwemikhiqizo ye-PCBA. Ngokulingisa imvelo yokushisa okushisa kakhulu, amaphutha angenzeka kumklamo womkhiqizo, ukukhethwa kwezinto ezibonakalayo noma inqubo yokukhiqiza kungatholakala kusengaphambili, ukuze umkhiqizo uthuthuke futhi ulungiswe ngaphambi kokuthi usetshenziswe ngokusemthethweni. Lokhu kusiza ukunciphisa izinga lokuhluleka komkhiqizo kwinqubo yangempela yokusebenzisa, thuthukisa ukuqina kanye nempilo yenkonzo yomkhiqizo, futhi uthuthukise ukuncintisana komkhiqizo emakethe. Noma ngabe emkhakheni we-elekthronikhi yabathengi, insimu yokulawula izimboni noma ama-elekthronikhi wezimoto, ezinye izinkambu, ukuhlolwa okuthembekile kwe-PCBA Thermal kungenye yezixhumanisi eziphambili zokuqinisekisa ukusebenza okujwayelekile kohlelo oluqinile lwe imishini ye-elekthronikhi.
