Umehluko phakathi komhlangano we-PCB ne-PCB

Yini i-PCBA

I-PCBA isifinyezo sokuthiumhlangano webhodi lesifunda onyathelisiwe.Kusho ukuthi, ama-PCB angenalutho adlula kuyo yonke inqubo ye-SMT ne-DIP plug-in.

I-SMT ne-DIP zombili izindlela zokuhlanganisa izingxenye ebhodini le-PCB.Umehluko omkhulu wukuthi i-SMT ayidingi ukubhoboza izimbobo ebhodini le-PCB.Ku-DIP, udinga ukufaka i-PIN embobeni ebhojwe.

Iyini i-SMT (Surface Mounted Technology)

I-Surface Mounted Technology ikakhulukazi isebenzisa umshini wokukhweza ukukhweza izingxenye ezithile ezincane ebhodini le-PCB.Inqubo yokukhiqiza yile: Ukuma kwebhodi le-PCB, ukunamathisela i-solder yokuphrinta, umshini wokukhweza ogibele, isithando somlilo sokugeleza kabusha kanye nokuhlola okuphelile.Ngokuthuthuka kwesayensi nobuchwepheshe, i-SMT ingaphinda ikhweze izingxenye ezithile ezinosayizi omkhulu, njengokuthi: ezinye izingxenye zemishini ezinosayizi omkhulu zingafakwa ebhodini lomama.

Umhlangano we-SMT PCBukuhlanganisa kuyazwela ekumeni kanye nosayizi wengxenye.Ngaphezu kwalokho, ikhwalithi ye-solder paste kanye nekhwalithi yokunyathelisa nayo idlala indima ebalulekile.

I-DIP “i-plug-in”, okusho ukufaka izingxenye ebhodini le-PCB.Ngenxa yobukhulu bezingxenye zinkulu futhi ayifanele ukukhwezwa noma uma umenzi engakwazi ukusebenzisa ubuchwepheshe bokuhlanganisa i-SMT, futhi ipulaki isetshenziselwa ukuhlanganisa izingxenye.Njengamanje, kunezindlela ezimbili zokubona i-plug-in ye-manual kanye ne-robot plug-in embonini.Izinqubo zokukhiqiza eziyinhloko yilezi: ukunamathisela i-glue emuva (ukuvimbela ukunamathisela kwe-tin endaweni okungafanele ihlanganiswe), i-plug-in, ukuhlolwa, i-wave soldering, ukuxubha ipuleti (ukususa amabala asele ngesikhathi sokudlula kwesithando somlilo) futhi kuqediwe. ukuhlola.

Yini i-PCB

I-PCB isho ibhodi lesifunda eliphrintiwe, elibizwa nangokuthi ibhodi lezintambo eziphrintiwe.I-PCB iyingxenye ebalulekile ye-elekthronikhi, futhi isekela izingxenye ze-elekthronikhi kanye nomthwali wokuxhuma ngogesi kwezingxenye ze-elekthronikhi.Ngenxa yokuthi yenziwe ngokuphrinta nge-elekthronikhi, futhi ibizwa ngokuthi ibhodi lesifunda eliphrintiwe.

Ngemuva kokusebenzisa i-PCB kumishini kagesi, ngenxa yokungaguquguquki kohlobo olufanayo lwe-PCB, iphutha le-wiring lingagwenywa, futhi izingxenye ze-elekthronikhi zingafakwa noma zinamathiselwe ngokuzenzakalelayo, zidayiswe ngokuzenzakalelayo, futhi zitholakale ngokuzenzakalelayo, ukuze kuqinisekiswe ikhwalithi. wemishini kagesi, kanye nokwenza ngcono ukukhiqizwa kwabasebenzi, kunciphise izindleko futhi kube lula ukulondolozwa.

I-PCB ingasetshenziswa kabanzi nangokwengeziwe, ngoba inezinzuzo eziningi ezihlukile:

1. Ukuminyana okuphezulu: Amashumi eminyaka, ukuminyana okuphezulu kwe-PCB kungathuthuka ngokuthuthukiswa kokuhlanganiswa kwe-IC nobuchwepheshe bokufaka.
2. Ukuthembeka okuphezulu.Ngochungechunge lokuhlola, ukuhlolwa nokuhlolwa kokuguga, i-PCB ingasebenza ngokwethembeka isikhathi eside (iminyaka eyi-20 ngokuvamile).
3. ŸUkuklama.Ngezidingo zokusebenza kwe-PCB (ezogesi, ezomzimba, zamakhemikhali, ezomshini, njll.), ukwakheka kwe-PCB kungenziwa ngokuklama 4. Ukumisa, ukumisa, njll., ngesikhathi esifushane nokusebenza kahle okuphezulu.
5. Ukukhiqiza.Ngokuphathwa kwesimanjemanje, ukulinganisa, isikali (ubuningi), okuzenzakalelayo nokunye ukukhiqizwa kungenziwa ukuze kuqinisekiswe ukuhambisana kwekhwalithi yomkhiqizo.
6. Ukuqina.Kusungulwe indlela yokuhlola ephelele uma kuqhathaniswa, amazinga okuhlola, amathuluzi okuhlola ahlukahlukene namathuluzi okuthola nokuhlonza ukufaneleka komkhiqizo we-PCB nempilo yesevisi.
7. ŸUkuhlangana.Imikhiqizo ye-PCB ayilungele kuphela ukuhlanganiswa okujwayelekile kwezingxenye ezahlukahlukene, kodwa futhi nokukhiqizwa kwenqwaba okuzenzakalelayo nokukhulu.Ngesikhathi esifanayo, i-PCB nezingxenye ezihlukahlukene zokuhlanganisa izingxenye zingahlanganiswa ukuze zakhe izingxenye ezinkulu, amasistimu, ngisho nomshini wonke.
8. ŸUkugcineka.Imikhiqizo ye-PCB kanye nezingxenye ezihlukahlukene zomhlangano wengxenye yakhelwe futhi ikhiqizwa ngokuvumelana nezindinganiso, lezi zingxenye nazo zilinganiselwe.Ngakho-ke, uma uhlelo luhluleka, lungashintshwa ngokushesha, kalula futhi ngokuguquguqukayo, futhi uhlelo lungabuyiselwa ngokushesha.Yebo, kunezibonelo ezengeziwe.Njengokwenza i-miniaturization yesistimu, ingasindi, idlulise isignali enesivinini esikhulu nokunye.

Uyini umehluko phakathi kwe-PCB ne-PCBA

1. I-PCB ibhekisela ebhodini lesifunda, kuyilapho i-PCBA ibhekisela ekuhlanganisweni kwe-plug-in yebhodi lesifunda, inqubo ye-SMT.
2. Ibhodi eliqediwe kanye nebhodi elingenalutho
3. I-PCB iyibhodi lesifunda eliphrintiwe, elenziwe nge-epoxy glass resin.Ihlukaniswe yaba izingqimba 4, 6 kanye 8 ngokuvumelana izingqimba ezahlukene signal.Okuvame kakhulu amabhodi angu-4 no-6-layer 4.I-chip nezinye izinto zokuchibiyela zinamathiselwe ku-PCB.
5. I-PCBA ingaqondwa njengebhodi lesifunda eliqediwe elingemva kokuqedwa kwenqubo ebhodini lesifunda futhi lingabizwa ngokuthi i-PCBA.
6. PCBA=Ibhodi Lesifunda Eliphrintiwe +Umhlangano
7. Ama-PCB angenalutho adlula kuyo yonke inqubo ye-SMT kanye ne-plug-in ye-dip, ibizwa nge-PCBA ngamafuphi.

I-PCB isifinyezo sebhodi lesifunda eliphrintiwe.Ngokuvamile kubizwa ngokuthi isekethe ephrintiwe eyenziwe ngesekethe ephrintiwe, izingxenye eziphrintiwe noma iphethini yokuqhuba eyakhiwe inhlanganisela yebhodi lesifunda eliphrintiwe kanye nebhodi lesifunda eliphrintiwe.Iphethini ye-conductive ehlinzeka ngoxhumano lukagesi phakathi kwezingxenye ze-insulating substrate ibizwa ngokuthi isekethe ephrintiwe.Ngale ndlela, isifunda esiphrintiwe noma ibhodi eliqediwe lesifunda esiphrintiwe libizwa ngokuthi ibhodi lesifunda eliphrintiwe, elibizwa nangokuthi ibhodi lesifunda eliphrintiwe noma ibhodi lesifunda eliphrintiwe.

Azikho izingxenye ku-PCB evamile, evame ukubizwa ngokuthi “ibhodi lezintambo eziphrintiwe (PWB)”

Ingabe ufuna ukuthola i-turnkey ethembekileUmkhiqizi womhlangano we-PCB?

Umgomo we-PCBFuture ukuhlinzeka imboni ngemishini ethembekile ethuthukisiwe yokwenziwa kwe-PCB kanye nezinsizakalo zokuhlanganisa kusukela ku-prototype kuye ekukhiqizeni ngendlela eyongayo.Inhloso yethu ukusiza umsebenzisi ngamunye abe umsebenzi ophelele, owenza imikhakha eminingi ongaletha ngokuzethemba imibono emisha, esezingeni eliphezulu ezobhekana nanoma iyiphi inombolo yemisebenzi efanele, izinkinga, nobuchwepheshe.
