Ulwazi lomugqa wokuhlanganisa we-SMT/PCB

I-Shenzhen Chengyuan Industrial Automation Equipment Co., Ltd. ihlinzeka ngezisombululo zobungcweti nemishini ezishintshayo yemigqa yokukhiqiza yasefekthri ehlakaniphile ye-SMT.

I-SMT mounter, i-lead-free reflow soldering, i-wave soldering engenamthofu, umshini wokumboza ngopende ohlelekile we-PCB, umshini wokunyathelisa, i-ovini yokwelapha.

Akungabazeki ukuthi ibhodi lesifunda eliphrintiwe (PCB) liyithuluzi eliyingqopha-mlando kubuchwepheshe babantu.

Ama-PCB asephenduke indlela yokuthuthukisa inqubo yokukhiqiza yezinto zikagesi.Esikhathini esedlule, lezi zinto zika-elekthronikhi ezakhiwe ngesandla kwakufanele zishintshwe amabhodi esekethe aphrintiwe.Lokhu kungenxa yokuthi imisebenzi eminingi izohlanganiswa ebhodini.

Qhathanisa ibhodi lesifunda lesibali sango-1968 nebhodi lomama lekhompyutha yesimanje.

1. Umbala.

Ngisho nakwabanye abantu abangazi ukuthi i-PCB ngeyani, ngokuvamile bayazi ukuthi i-PCB ibukeka kanjani.Okungenani abukeka sengathi anesitayela esisodwa sendabuko, esiluhlaza.Lokhu okuluhlaza empeleni umbala osobala we-solder mask glass paint.Nakuba igama le-mask solder liyi-solder mask, umsebenzi walo oyinhloko ukuvikela isifunda esimboziwe kusuka kumswakama nothuli.

Ngokuqondene nokuthi kungani imaski ye-solder iluhlaza, isizathu esiyinhloko ukuthi okuluhlaza yizinga lokuvikela ezempi.Ngokokuqala ngqa, ama-PCB emishini yezempi asebenzise imaski ye-solder ensimini ukuvikela ukwethembeka kwesifunda.

Amamaski e-solder manje atholakala ngemibala eyahlukene, okuhlanganisa emnyama, ebomvu, ephuzi, neminye.Phela, okuluhlaza akuyona indinganiso yezimboni.

2. Ngubani owasungula i-PCB?

Amabhodi esekethe okuqala aphrintiwe angalandelelwa emuva kunjiniyela wase-Austria uCharles Ducas ngo-1920, owaphakamisa umqondo wokuqhuba ugesi ngoyinki (izintambo zethusi zokunyathelisa epuletini elingezansi).Wasebenzisa ubuchwepheshe be-electroplating ukwenza izintambo ngqo phezu kwesivikelo futhi wenza i-PCB prototype.

Izintambo zensimbi emabhodini esekethe ekuqaleni zaziyithusi, ingxubevange yethusi ne-zinc.Lokhu okusungulwe okuphazamisayo kuqeda inqubo eyinkimbinkimbi yezintambo zamasekethe kagesi, okuqinisekisa ukwethembeka kokusebenza kwesifunda.Le nqubo ayizange ingene esigabeni sokufaka isicelo kwaze kwaba sekupheleni kweMpi Yezwe II.

3. Maka.

Kunamamaki amaningi amhlophe ebhodini lesekethe eliluhlaza.Iminyaka eminingi, abantu babengaqondi ukuthi kungani lawa maphrinti amhlophe ayebizwa “ngezingqimba zesikrini sikasilika”.Ngokuyinhloko zisetshenziselwa ukukhomba ulwazi lwengxenye ebhodini lesifunda nokunye okuqukethwe okuhlobene nebhodi lesifunda.Lolu lwazi lungasiza onjiniyela besifunda ukuthi bahlole amaphutha ebhodini.
