Siziingcali ekwenzeni ii-PCB zoshishino ezineeleya ezininzi kwaye sinikezela ngeenkonzo ze-PCBA ezikwindawo enye. Inkqubo yethu iqala ngefayile okanye i-Gerber ethunyelwe ngumsebenzisi. Emva kokufumana le fayile, iinjineli zethu ziyayihlola kwaye ziseke inkqubo yokuvelisa ukuze zenze iibhodi ze-PCB kunye nezinto ze-PCBA zolawulo lwezoshishino kusetyenziswa ubuchwepheshe obahlukeneyo. I-RICHPCBA inokuhlangabezana neemfuno zabathengi kwiiprojekthi ezilula ukuya kwezintsonkothileyo, iibhetshi ezincinci ukuya kwindibano ye-PCB ephezulu, kunye neenkampani ezintsha ukuya kwiinkampani ezinkulu zezimboni. Iqela lethu leengcali liqhuba iiprojekthi ngabaphathi beeprojekthi ze-1V1, lixhaswa ngamaqela okuthenga, ubunjineli, ukuvelisa, kunye nolawulo lomgangatho.

Izinto zoYilo lwePCB yezeShishini
Uyilo lweCandelo
Ukubekwa kwezixhobo kwisakhiwo sebhodi yinto ebalulekileyo ekufuneka iqwalaselwe xa kuyilwa iibhodi zePCB zolawulo lwemizi-mveliso. Ukubekwa kwezixhobo ngendlela engafanelekanga kunokuchaphazela ukuthembeka nokusebenza kwemveliso yokugqibela. Ngexesha loyilo lwebhodi yePCB, kufuneka kuthathwe unonophelo olukhethekileyo ukuqinisekisa ukuba izixhobo zifakwe ebhodini ubuncinane isithuba se-100 mils phakathi kwemiphetho yebhodi kunye nezixhobo ezifakelweyo. Oku kuqinisekisa ukuba ubukhulu bebhodi kunye nemingxunya efakelweyo iyahambelana.
I-EMI kunye ne-RFI
Kwimisebenzi yemizi-mveliso, kubalulekile ukunciphisa imiphumo ye-Electromagnetic Interference (EMI) kunye ne-Radio Frequency Interference (RFI), enokubangela ingxolo kwaye iphazamise ukusebenza kwe-PCBA. Ngenxa yoku, i-Rich PCBA inikezela ngamaqhinga aliqela:
Uyilo lwebhodi: Ukuze unciphise umngcipheko wokudibana kwengxolo, yahlula iisekethe ezisebenzisa isandi esiphezulu kwiisekethe ezisebenzisa isandi esiphantsi kwaye ugcine imiqondiso kude neeplani zamandla kunye nomhlaba. Imiqondiso yesignali kufuneka ibe mifutshane kangangoko, ngelixa iplani zamandla kunye nomhlaba kufuneka zibe nkulu kangangoko kwaye zihanjiswe ngemibhobho ephantsi yokungenisa umoya ukunciphisa ukuxinana kwenethiwekhi yamandla.
Izinto zokucoca: Yongeza izinto zokucoca ezifana nee-capacitors kunye nee-inductors kumbane nakwimigca yesignali ukuze uhluze ingxolo engafunekiyo.
Iindlela zokuGxina nokuKhusela: Faka izinto ezinobuthathaka kwiikheyiji zeFaraday ukuvimba i-EMI kunye ne-RFI.
Ukhetho Lwezinto: Khetha izinto zebhodi yesekethe ezinesiseko esisemgangathweni kunye nesikhuselo. Sebenzisa iintambo ezikhuselweyo ukuqhagamshela ibhodi kwizixhobo zangaphandle ukuthintela ukudibana kwesignali okungafunekiyo.
Izixhobo zePCB zoLawulo lweMizi-mveliso
Ukukhethwa kwezinto zokwenziwa kwe-PCB kubaluleke kakhulu kwaye kufuneka kusekelwe kwindawo ethile yokusebenza. Izinto zokusetyenziswa kwe-PCB ezisetyenziswa kushishino kufuneka zikwazi ukumelana neemeko ezinzima, ezinje ngobushushu obuphezulu, i-voltage ephezulu, ukufuma, ukungcangcazela, kunye nokuvezwa ngamakhemikhali. Ezinye zezinto ezisetyenziswa kakhulu kwi-PCB zoshishino zezi:
● I-Polyimide: Le nto inamandla okusebenza kakuhle inokumelana namaqondo obushushu agqithisileyo ukuya kuthi ga kwi-400°C kwaye isetyenziswa rhoqo kwiindlela zokulawula i-aerospace, emkhosini, nakwiindlela zokulawula i-industrial ezisebenzisa amaqondo obushushu aphezulu.
● Iseramikhi: I-PCB yeseramikhi yenziwe nge-substrate yeseramikhi kunye neentsalela zesinyithi. Zinomoya oqhuba kakuhle kakhulu wobushushu kwaye zinokuphatha amaqondo obushushu aphezulu kunye neekhemikhali eziqatha. Zisetyenziswa kakhulu kwizixhobo ze-elektroniki ezinamandla kunye nokusetyenziswa kwamaza aphezulu.
● I-PTFE: I-PTFE okanye i-polytetrafluoroethylene yi-fluoropolymer eneempawu zokukhusela umbane ezibalaseleyo ezinokumelana namaqondo obushushu aphezulu ukuya kuthi ga kwi-260°C. Isetyenziswa kakhulu kwiindawo ezisetyenziswa rhoqo kakhulu nakwii-microwave, kunye neendawo ezinobungozi beekhemikhali.
● FR-4: Le nto idityanisiweyo eyenziwe ngelaphu le-fiberglass elukiweyo kunye ne-epoxy resin yeyona nto isetyenziswa kakhulu kwi-PCB ngokubanzi, kuquka ne-industrial. I-FR4 PCB ineempawu ezilungileyo zokukhusela umbane kwaye inokumelana namaqondo obushushu aphezulu kunye neekhemikhali.
