Ubona izendlalelo eziyisishiyagalombili zokwakha kufayela le- PCB

Kubalulekile ukuqonda nokuhlukanisa izingqimba ze-PCB. Ukuze uqonde kangcono ukushuba ngqo kwe-PCB, kudingeka ukuhlukaniswa okuhle ukuze kuqinisekiswe ukuthi i-PCB isebenza kahle kakhulu. Izendlalelo ezilandelayo zivame ukubonwa kuma-PCBS afakiwe. Lokhu kungahluka, kuye ngenani lezendlalelo, umklami, nomklamo uqobo.

L ungqimba lwemishini

Lona ungqimba oluyisisekelo lwe-PCB. Isetshenziswa njengohlaka lwebhodi lesifunda. Lolu uhlaka lomzimba oluyisisekelo lwe-PCB. Lolu ungqimba futhi lwenza umklami akwazi ukuxhumana nendawo ngqo yemigodi nokusikeka kwayo.

L gcina ungqimba

Lesi sendlalelo sifana nesendlalelo semishini ngoba singasetshenziswa futhi njengontaba. Kodwa-ke, umsebenzi wesendlalelo sokubamba ukuchaza ubungako bokubeka izinto zikagesi, i-wiring yesifunda, njll. Akukho ngxenye noma isekethe engabekwa ngaphandle kwalomngcele. Lesi sendlalelo sinciphisa ukuxhunywa kwamathuluzi we-CAD ezindaweni ezithile.

L umzila wokuhambisa

Isendlalelo somzila sisetshenziselwa ukuxhuma izingxenye. Lezi zingqimba zingatholakala ngapha nangapha kwebhodi lesifunda. Ukubekwa kwezendlalelo kuya kumklami, owenza izinqumo ngokususelwa kuhlelo lokusebenza nezinto ezisetshenzisiwe.

L Indiza eyisisekelo nendiza yamandla

Lezi zingqimba zibalulekile ekusebenzeni kahle kwe-PCB. Ukugxila phansi nokusatshalaliswa kwesisekelo kulo lonke ibhodi lesifunda nezinto zalo. Isendlalelo samandla, ngakolunye uhlangothi, sixhunywe kwesinye sezilinganiso ezise-PCB uqobo. Zombili lezi zingqimba zingavela phezulu, phansi, nangamapuleti e-PCB.

L Indiza yokuhlukanisa

Indiza ehlukanisiwe empeleni iyindiza yamandla ehlukanisiwe. Isibonelo, indiza yamandla ebhodini ingahlukaniswa kabili. Ingxenye eyodwa yendiza yamandla ingaxhunywa ku- + 4V kanti enye ingxenye iye ku -4V. Ngakho-ke, izingxenye ebhodini zingasebenza ngama-voltages amabili ahlukene ngokuya ngokuxhumana kwazo.

L Isendlalelo sekhava / sesikrini

Isendlalelo sesilkisi sisetshenziselwa ukwenza omaka bombhalo bezinto ezibekwe ngaphezulu kwebhodi. Imbondela yenza umsebenzi ofanayo ngaphandle kwaphansi kwepuleti. Lezi zingqimba zisiza enqubweni yokukhiqiza nokulungisa iphutha.

L ukumelana Welding ungqimba

Izintambo zensimbi nezimbobo zokungena emabhodini wesifunda kwesinye isikhathi kubhekiswa kuzo njengezimbozo zokuvikela izingqimba zokumelana ne-solder. Lesi sendlalelo sigcina uthuli, uthuli, umswakama nezinye izinto zemvelo kude nebhodi.

L ungqimba lwe-solder paste

Sebenzisa ukunamathisela kwe-solder ngemuva kokufakwa kwendawo yomhlangano. Kuyasiza ukuhlanganisa izingxenye ebhodini lesifunda. Iphinde ikusize ukugeleza kwamahhala kwe-solder ku-PCB equkethe izinto ezifakwe ngaphezulu.

Zonke lezi zingqimba kungenzeka zingabi khona ku-PCB eyodwa-ungqimba. Lezi zingqimba zisuselwa ekwakhiweni kwebhodi lesifunda eliphrintiwe. Lezi zingqimba zokuklama zisiza ukulinganisa ubukhulu be-PCB ephelele lapho ubukhulu be-micron ngayinye bubalwa. Le mininingwane izokusiza ugcine ukubekezelelana okuqinile okutholakala kumiklamo eminingi ye-PCB.
