I-PWB vs. PCB: Uyini Umehluko?

Emhlabeni wezinto zikagesi, amagama athi Printed Wiring Board (PWB) kanye nePrinted Circuit Board (PCB) avame ukusetshenziswa ngokushintshana, kodwa kunomehluko ocashile phakathi kwawo. Ukuqonda lo mehluko kubalulekile kochwepheshe ekwakhiweni kwe-elekthronikhi nasekukhiqizeni.

Kungakhathaliseki ukuthi idokhumenti ibiza umkhiqizo ngokuthi i-PWB noma i-PCB, iphakheji yokukhiqiza isadinga izinto ezilawulwayo, ukubekezelelana, kanye nokuhlolwa; xhumanisa amagama enziwe ekwakhiweni kwebhodi lesifunda eliphrintiwe elisebenzayo kanye nokukhethwa kwe-PCB substrate.

Iyini Ibhodi Lezintambo Eziphrintiwe (PWB)?

I-PWB isho ibhodi elihlinzeka ngoxhumano lukagesi phakathi kwezingxenye kodwa lingafaki izingxenye zangempela ngokwazo. Ngokuyinhloko iphathelene nezintambo noma iminonjana eyenziwe ngezinto zokuqhuba njengethusi. Ezigabeni zokuqala zokuklanywa kwe-elekthronikhi, igama elithi PWB lalivame ukusetshenziswa, ikakhulukazi lapho ukusebenza kwakugxile kakhulu ezintanjeni ezixhumayo kunasezinkingeni zesekethe.

Iyini Ibhodi Lesifunda Eliphrintiwe (PCB)

I-PCB ayifaki nje kuphela izintambo nezixhumi kodwa futhi ihlanganisa ukusebenza okuphelele kwedivayisi ye-elekthronikhi okuhlanganisa izingxenye ezifana nezimbangi, ama-capacitor, nama-IC. Ihlanganisa kokubili ukwakheka komzimba (izintambo kanye ne-substrate) kanye nokusebenza kukagesi (izingxenye kanye nokujikeleza). Njengoba izinto ze-elekthronikhi zishintsha ukuze zibe yinkimbinkimbi kakhulu, igama elithi PCB liye ladlanga kakhulu, libonisa isimo esihlanganisiwe sokujikeleza kanye nezingxenye.

Umehluko Oyinhloko phakathi kwe-PWB vs PCB

Ubuchwepheshe

Ama-PWB agcizelela i-substrate ebonakalayo kanye nokuhlelwa kwezintambo noma imikhondo ebhodini.Ubuchwepheshe obusetshenziswa kuma-PWB buphathelene ngokuyinhloko nezinto zebhodi (ezifana ne-FR4, uhlobo oluvamile lwe-fiberglass), inani lezingqimba zezintambo, kanye izindlela zokwendlalela lezi zintambo noma imikhondo ebhodini.Ama-PWB angase ahlanganise ubuchwepheshe obuhlukahlukene bokudala izindlela zokuqondisa, njengokunamathisela amashidi ethusi alamiwe endaweni engaphansi engaphenduki.Izinqubo zobuchwepheshe ezihilelekile ekukhiqizeni i-PWB zihloselwe ukuqinisekisa ubuqotho. yesakhiwo sezintambo, njengokuvala okulungile phakathi kwezendlalelo nokuqina kwemikhondo.

Ubuchwepheshe be-PCB budlulela ngale kwe-substrate ebonakalayo yebhodi kanye nezintambo ezihlanganisa ukukhwezwa nokuhlanganiswa kwezinto zikagesi.Ubuchwepheshe obusetshenziswa kuma-PCB abuhlanganisi nje kuphela impahla yebhodi nesakhiwo sezintambo kodwa nezindlela zokuhlanganisa izingxenye zebhodi ebhodini, njenge-Surface Mount Technology ( I-SMT) noma i-Threhth-Hole Technology (THT).Ama-PCB abandakanya ubuchwepheshe obuhlobene nokubeka ingxenye nesikhala, ukuphathwa kwe-thermal, kanye nokuqinisekisa ukuthi uxhumo lukagesi nemishini luthembekile.Ama-PCB athuthukile angase ahlanganise imiklamo enezingqimba eziningi, umzila oyinkimbinkimbi ukuze kuhlangatshezwane namasekethe ayinkimbinkimbi, nama-coatings akhethekile. noma iqedelela ukuvikela noma ukusebenza okuthuthukisiwe.

Izicelo

Ama-PWB asetshenziswa ezinhlelweni lapho kudingeka khona izintambo eziyisisekelo noxhumo lukagesi ngaphandle kokuhlanganiswa kwezinto ezisebenzayo zikagesi. Ama-PWB angasetshenziswa ezigabeni ze-prototyping ukuhlola ukwakheka kanye nezintambo zesekhethi ngaphambi kokuhlanganiswa okugcwele kwezingxenye ku-PCB.

• Ama-PCB athandwa lapho kudingeka khona ukusebenza okuthuthukile, njengokusebenza kwekhompuyutha, ezezimoto, kanye nezokuxhumana.
• I-Consumer Electronics: Ama-PCB abalulekile ezinhlobonhlobo zezinto zikagesi zabathengi njengama-smartphone, amakhompyutha, nomabonakude, lapho kudingeka khona ukujikeleza okuyinkimbinkimbi nezinto eziningi.
• Amadivayisi Ezokwelapha: Ama-PCB athuthukile asetshenziswa emishinini yezokwelapha efana nemishini ye-MRI, iziqapha zenhliziyo, namanye amathuluzi okuxilonga.
• Imboni Yezimoto: Izimoto zesimanje zisebenzisa ama-PCB kakhulu kumasistimu okulawula, amasistimu we-infotainment, nezici zokuphepha zikagesi.
• Izicelo Zezimboni: Ama-PCB asetshenziswa emishinini yokukhiqiza, izimpahla zikagesi, nasezinhlelweni zokulawula zokuzenzakalela nokuqapha.
• Ezokuxhumana: Zibalulekile ezinsizakalweni zokuxhumana, ingqalasizinda yokuxhumana nobuchwepheshe obungenawaya.
• I-Aerospace kanye Nokuvikela: Ama-PCB kule mikhakha adinga ukuhlangabezana namazinga athembeke kakhulu ukuze asetshenziswe kumasathelayithi, imikhumbi-mkhathi, nempahla yezempi.
• I-inthanethi Yezinto (IoT): Ngokukhula kwe-IoT, ama-PCB abalulekile kumadivayisi axhunyiwe, ubuchwepheshe basekhaya obuhlakaniphile, kanye nobuchwepheshe obugqokekayo.

Indlela Yokukhetha Phakathi Kwabo

Ubunkimbinkimbi beSekethe:

Uma ubhekene nesekethe elula engadingi ukuhlanganiswa kwezingxenye ze-elekthronikhi eziningi noma eziyinkimbinkimbi.
Uma iphrojekthi yethu ibandakanya amasekhethi ayinkimbinkimbi anezingxenye eziningi, njengoba ama-PCB enzelwe ukusekela ukuhlanganiswa okunjalo ngokuphumelelayo.

Ukuhlanganiswa Kwengxenye:

Uma udinga kuphela ibhodi yokubeka izintambo nezindlela zikagesi ngaphandle kokukhweza noma yiziphi izingxenye ze-elekthronikhi.
Uma udinga ukukhweza futhi udayise izingxenye ze-elekthronikhi ebhodini, ikakhulukazi kumishini kagesi yesimanje.

I-Prototype nokuhlola:

Sebenzisa i-PWB ukwenza i-prototyping yokuqala nokuhlola lapho ukugxila okuyinhloko kusekuhlelweni nasekufakeni izintambo kwesekhethi.
Ukushintshela ku-PCB uma umklamo usudlulela ngale kwesiteji futhi udinga ibhodi elisebenza ngokugcwele elinazo zonke izingxenye ezidingekayo.

Izindleko zokucatshangelwa:

Ama-PWB angase angabizi kakhulu ezinhlelweni eziyisisekelo noma izigaba zokuqala zokuklama ngenxa yobulula bawo.
Ama-PCB, nakuba ebiza kakhulu, ahlinzeka ngenani elengeziwe ezinhlelweni eziyinkimbinkimbi ngenxa yekhono lawo lokusekela imisebenzi ye-elekthronikhi eyinkimbinkimbi.

Uhlelo lokusebenza lokugcina:

Ngokusebenza okuyisisekelo kwe-elekthronikhi noma izinhlelo zokusebenza lapho kungadingeki ukuhlanganiswa kwengxenye esebenzayo, i-PWB ingase yanele.
Okwama-electronics abathengi, izinto zezokwelapha, izinhlelo zokusebenza zezimoto, ezokuxhumana, nezinye izinkambu ezithuthukile, ama-PCB ayinketho ekhethwayo ngenxa yokuhlukahluka kwawo namandla okusekela imisebenzi eyinkimbinkimbi.

Ngezinqumo zokukhiqiza ezihlobene, i-Highleap iphinde ibhale phansi ukubuyekezwa komklamo wemaski we-solder kanye nokulungiswa kwefayela le-Gerber , okungasiza ekuvimbeleni amanothi angacacile kuphakheji yesilinganiso.
