Umkhiqizi we-PCB kanye ne-PCBA yezimboni
I-PCBA Yezimboni - Amabhodi wesekethe emishini yokulawula yezimboni
I-PCBA yezimboni, eyaziwa nangokuthi ibhodi lokulawula lezimboni, iyibhodi yesekethe eyenzelwe ukumelana nokushaqeka, ukudlidliza, amazinga okushisa aphezulu, umswakama, kanye nothuli emishinini yezimboni. Le PCBA isetshenziselwa ukwenza imisebenzi eminingi embonini yokulawula yezimboni. Yenzelwe ukumisa isekethe yephrojekthi ngendlela ehlangene, evumela ukuthi ugesi ugeleze ngokunembile endleleni edingekayo futhi ithuthukise ukusebenza komkhiqizo. Lawa mabhodi futhi ayizingxenye ezibalulekile zamaphrojekthi nemishini yokulawula yezimboni, esiza ukukala nokulungisa amapharamitha amaningi omugqa wokuhlanganisa, nokuthola inani elifanele elingokoqobo.
Inkampani ye-PCBA Yemishini Yezimboni – iRichpcba
Uma ufuna amabhodi e-PCB/PCBA okulawula izimboni asezingeni eliphezulu ngamanani angabizi, i-www.richpcba.com iyona engcono kakhulu. Yasungulwa eShenzhen, eShayina ngo-2004, singabakhiqizi be-PCB assembly abaphendukela phambili abakhonze izinkulungwane zamabhizinisi asekhaya nakwamanye amazwe eminyakeni embalwa edlule. Izinsizakalo zethu zokukhiqiza azikhawulelwe ku-PCB kanye ne-PCBA; senza futhi izidingo ezikhethekile, ukuvuselela, kanye nokuguqulwa okucelwe amakhasimende ukuze aneliseke. Ngemikhuba yethu yokusebenza yobungcweti kanye nesimo sengqondo somsebenzi esizinikele, siye saqashelwa abakhiqizi abaningi abaphambili emkhakheni wezimboni.
Singochwepheshe ekukhiqizeni ama-PCB ezimbonini anezingqimba eziningi futhi sihlinzeka ngezinsizakalo ze-PCBA ezitholakala endaweni eyodwa. Inqubo yethu iqala ngefayela noma i-Gerber ethunyelwe ngumsebenzisi. Ngemva kokuthola leli fayela, onjiniyela bethu babuyekeza futhi basungule inqubo yokukhiqiza ukuze bakhe amabhodi e-PCB nezinto ze-PCBA zokulawula izimboni besebenzisa ubuchwepheshe obuhlukene. I-RICHPCBA ingahlangabezana nezidingo zamakhasimende zamaphrojekthi alula kuya kwayinkimbinkimbi, amaqembu amancane kuya ekuhlanganisweni kwe-PCB okunomthamo omkhulu, kanye nezinkampani ezintsha kuya kuma-giants ezimboni. Ithimba lethu lochwepheshe lenza amaphrojekthi ngabaphathi bephrojekthi ye-1V1, besekelwa amaqembu okuthenga, ubunjiniyela, ukukhiqiza, kanye nokulawula ikhwalithi.

Izici Zokuklama ze-PCB Yezimboni
Ukuhlelwa Kwengxenye
Ukubekwa kwezingxenye ekwakhiweni kwebhodi kuyisici esibalulekile okufanele sicatshangelwe lapho kuklanywa amabhodi e-PCB okulawula izimboni. Ukubekwa kwezingxenye okungalungile kungathinta ukuthembeka nokusebenza komkhiqizo wokugcina. Ngesikhathi sokuklama ibhodi le-PCB, kufanele kuthathwe ukunakekelwa okukhethekile ukuqinisekisa ukuthi izingxenye zifakiwe ebhodini elinesikhala okungenani sama-mils ayi-100 phakathi kwemiphetho yebhodi kanye nezingxenye ezifakiwe. Lokhu kuqinisekisa ukuthi ubukhulu bebhodi kanye nezimbobo ezifakiwe ziyahambisana.
I-EMI kanye ne-RFI
Ezisetshenzisweni zezimboni, kubalulekile ukunciphisa imiphumela ye-Electromagnetic Interference (EMI) kanye ne-Radio Frequency Interference (RFI), okungadala umsindo futhi kuphazamise ukusebenza kwe-PCBA. Ngenxa yalokhu, i-Rich PCBA inikeza amasu amaningana:
Ukuhlelwa kwebhodi: Ukuze unciphise ingozi yokuxhumanisa umsindo, hlukanisa amasekethe anemvamisa ephezulu kumasekethe anemvamisa ephansi futhi ugcine ama-trace signal kude namandla kanye nezindiza zomhlaba. Ama-trace signal kufanele abe mafushane ngangokunokwenzeka, kuyilapho ama-power kanye nezindiza zomhlaba kufanele abe makhulu ngangokunokwenzeka futhi aqondiswe ngokuxhumeka kwemigodi ye-inductance ephansi ukuze kuncishiswe ukuvinjelwa kwenethiwekhi yamandla.
Izingxenye zokuhlunga: Faka izingxenye zokuhlunga ezifana nama-capacitor nama-inductor kumandla kanye nemigqa yesignali ukuze uhlunge umsindo ongafuneki.
Amasu Okumisa Nokuvikela: Faka izingxenye ezibucayi emakhejini eFaraday ukuze uvimbele i-EMI ne-RFI.
Ukukhethwa Kwezingxenye: Khetha izingxenye zebhodi lesifunda ezinesisekelo kanye nesivikelo sekhwalithi ephezulu. Sebenzisa izintambo ezivikelwe ukuxhuma ibhodi kumadivayisi angaphandle ukuvimbela ukuhlanganiswa kwesignali okungafuneki.
Izinto ze-PCB zokulawula izimboni
Ukukhethwa kwezinto zokwakha i-PCB kubalulekile futhi kufanele kusekelwe endaweni ethile yokusebenza. Izinto zokwakha ama-PCB asetshenziswa embonini kumele zikwazi ukumelana nezimo ezinzima, njengokushisa okuphezulu, i-voltage ephezulu, umswakama, ukudlidliza, kanye nokuchayeka kumakhemikhali. Ezinye izinto ezivame ukusetshenziswa kuma-PCB ezimboni yilezi:
● I-Polyimide: Le nto esebenza kahle kakhulu ingamelana namazinga okushisa aphezulu afinyelela ku-400°C futhi ivame ukusetshenziswa ezindleleni zokulawula izindiza, ezempi, kanye nezimboni ezisebenzisa amazinga okushisa aphezulu.
● I-Ceramic: I-PCB yobumba yenziwe nge-substrate yobumba kanye nezinsimbi ezisele. Ine-conductivity enhle kakhulu yokushisa futhi ingaphatha amazinga okushisa aphezulu kanye namakhemikhali aqinile. Ivame ukusetshenziswa kuma-electronics anamandla kanye nezinhlelo zokusebenza zemvamisa ephezulu.
● I-PTFE: I-PTFE noma i-polytetrafluoroethylene iyi-fluoropolymer enezakhiwo ezinhle kakhulu zokuvimbela ugesi ezingamelana namazinga okushisa aphezulu afinyelela ku-260°C. Ivame ukusetshenziswa ezindaweni ezivame kakhulu ukusetshenziswa kanye ne-microwave, kanye nasezindaweni zamakhemikhali ezinzima.
● FR-4: Le nto ehlanganisiwe eyenziwe ngendwangu ye-fiberglass elukiwe kanye ne-epoxy resin iyinto esetshenziswa kakhulu kuma-PCB ajwayelekile, kufaka phakathi izimboni. I-FR4 PCB inezakhiwo ezinhle zokuvikela ugesi futhi ingamelana namazinga okushisa aphezulu kanye namakhemikhali.
