I-PCB yoShishino kunye noMenzi we-PCBA
I-PCBA yoShishino – Iibhodi zeeSekethe zoomatshini bolawulo lwamashishini
I-PCBA yoshishino, eyaziwa ngokuba yibhodi yolawulo lwemizi-mveliso, yibhodi yesekethe eyenzelwe ukuxhathisa ukothuka, ukungcangcazela, amaqondo obushushu agqithisileyo, ukufuma, kunye nothuli kwizixhobo zoshishino. Le PCBA isetyenziselwa ukwenza imisebenzi emininzi kushishino lolawulo lwemizi-mveliso. Yenzelwe ukuqwalasela isiphaluka seprojekthi ngendlela edibeneyo, evumela ukuba i-current ihambe ngokuchanekileyo kwindlela efunekayo kwaye ikhulise ukusebenza kwemveliso. Ezi bhodi nazo ziyinxalenye ebalulekileyo yeeprojekthi zolawulo lwamashishini kunye nezixhobo, ezinceda ukulinganisa kunye nokuqwalasela iiparitha ezininzi zomgca wendibano, kunye nokufumana ubungakanani obuchanekileyo bomzimba.

Imiba yoYilo lwePCB yoShishino
UYilo lweCandelo
Ukubekwa kwamacandelo kuyilo lwebhodi yinto ebalulekileyo ekufuneka iqwalaselwe xa kuyilwa iibhodi zePCB zolawulo lwamashishini. Ukubekwa kwecandelo elingafanelekanga kunokuchaphazela ukuthembeka kunye nokusebenza kwemveliso yokugqibela. Ngexesha loyilo lwebhodi ye-PCB, kufuneka kuthathelwe ingqalelo ekhethekileyo ukuze kuqinisekiswe ukuba amacandelo afakwe ebhodini kunye nobuncinci besithuba se-100 mils phakathi kwemiphetho yebhodi kunye namacandelo anyusiweyo. Oku kuqinisekisa ukuba imilinganiselo yebhodi kunye nemingxuma ephakanyisiweyo iyahambelana.
EMI & RFI
Kwizicelo zamashishini, kubalulekile ukunciphisa iziphumo ze-Electromagnetic Interference (EMI) kunye neRadio Frequency Interference (RFI), enokubangela ingxolo kwaye iphazamise ukusebenza kwe-PCBA. Ukuza kuthi ga ngoku, i-PCBA eSityebi ibonelela ngezicwangciso ezininzi:
Uyilo lwebhodi:Ukunciphisa umngcipheko wokudibanisa ingxolo, hlukanisa iisekethe eziphezulu ze-frequency ukusuka kwiisekethe eziphantsi kwaye ugcine iimpawu zesignali kude kumandla kunye neenqwelomoya zomhlaba. Umkhondo wophawu kufuneka ube mfutshane kangangoko, ngelixa amandla kunye neenqwelomoya zomhlaba kufuneka zibe zikhulu ngokusemandleni kwaye zihanjiswe ngoqhagamshelo lomngxuma wokuthotywa ophantsi ukuze kuncitshiswe ukuthintela kothungelwano lwamandla.
Amalungu okuhluza:Yongeza izinto zokucoca ezifana nee-capacitors kunye ne-inductors kumandla kunye nemigca yesignali ukuhluza ingxolo engafunekiyo.
IiNdlela zokuSebenza kunye nokuKhusela: Vala amacandelo abuthathaka kwiikheji zaseFaraday ukuvala i-EMI kunye ne-RFI.
Ukukhethwa kweCandelo:Khetha amacandelo ebhodi yesekethe kunye nomgangatho ophezulu wokumisa kunye nokukhusela. Sebenzisa iintambo ezikhuselekileyo ukudibanisa ibhodi kwizixhobo zangaphandle ukukhusela ukudibanisa komqondiso okungafunekiyo.
Izinto zePCB zoLawulo lwezoShishino
Ukukhethwa kwezinto zokwenziwa kwePCB kubalulekile kwaye kufuneka kusekwe kwindawo ethile yokusebenza. Izixhobo zePCB ezisetyenziswa kushishino kufuneka zikwazi ukumelana neemeko ezinzima, ezinje ngobushushu obuphezulu, amandla ombane aphezulu, ukufuma, ukungcangcazela, kunye nokuvezwa kweekhemikhali. Ezinye izinto ezisetyenziswa ngokuqhelekileyo kwii-PCB zemizi-mveliso zezi:
● Polyimide:Esi sixhobo siphezulu sinokumelana namaqondo obushushu ukuya kuthi ga kwi-400 ° C kwaye isoloko isetyenziswa kwi-aerospace, emkhosini, nakwi-high-temperature control applications.
● I-Ceramic:I-PCB ye-ceramic yenziwe nge-ceramic substrate kunye neempawu zetsimbi. Zine-conductivity egqwesileyo ye-thermal kwaye zinokubamba amaqondo aphezulu kunye neekhemikhali ezinzima. Ngokuqhelekileyo zisetyenziswa kwi-electronics yamandla kunye nezicelo eziphezulu-frequency.
● PTFE:I-PTFE okanye i-polytetrafluoroethylene yi-fluoropolymer eneempawu ezigqwesileyo zokugquma umbane ezinokumelana nobushushu obuphezulu ukuya kuma-260°C. Isetyenziswa ngokuqhelekileyo kwi-high-frequency kunye ne-microwave applications, kunye neendawo ezinobungozi bemichiza.
● FR-4:Le imathiriyeli edibeneyo eyenziwe ngelaphu elilukiweyo le-fiberglass kunye ne-epoxy resin yeyona nto isetyenziswa kakhulu kwiiPCBs ngokubanzi, kubandakanya nemizi-mveliso. I-FR4 PCB ineempawu ezilungileyo zokugquma umbane kwaye inokumelana namaqondo obushushu aphezulu kunye neekhemikhali.
