Kutheni u-Fr4 esetyenziselwa ibhodi ye-PCB

Yintoni i-Fr-4?

I-Fr-4 yezinto ezifudusa ilaphu ye-fiber yeglasi, luhlobo lweBhodi yeBhodi eluhlaza kunye nezinto ezisezantsi, igama le-resin elinganyangekiyo kufuneka likwazi ukuzicime emva kokutsha . Ukucaciswa kwezinto. Eyona nto isetyenziswa rhoqo kwi-PCB (iBhodi yeSekethe eprintiweyo), ngokuBanzi ngokuNinzi, iBhodi yePakethi ye-PCB yenziwa ngoku! Ngenxa yamandla ayo aphezulu kunye nokubuyiswa kwedayaki, uninzi lweebhodi zesekethe ziya kukhetha uFr-4 njengezinto ezisisiseko.

2. Yintoni i-PCB kunye nokuqulunqwa kwayo?

I-PCB sisifinyezo sebhodi yesekethe esiprintiweyo ngesiNgesi. Igama lesiphaluka lesiTshayina liprintwe kwiBhodi yeSiphaluka eliPrintwe, ekwabizwa ngokuba yiBhodi yeSiphako eprintiweyo kwaye iprintwe iprintiweyo. Yinxalenye ebalulekileyo ye-elektroniki. Ngumnikezeli wonxibelelwano lombane kwizinto ze-elektroniki.

I-PCB iqala ngeyona ndawo ibalulekileyo: Ikhubalo, elinamacandelo aliqela, ngalinye lidlala indima ebalulekileyo ekusebenzeni kwe-PCB yokugqibela. Ezi ngxelo zokutshintsha zibandakanya:

• I-subtate: Olu sisiseko se-PCB. Yenza i-PCB ingqongqo.

• Ubhedu: Yongeza umaleko omncinci we-foil ye-foil esebenzayo kwicala ngalinye le-PCB-kwelinye icala ukuba yi-PCB esecaleni, okanye kumacala omabini ukuba yi-PCB esecaleni. Lo ngumkhondo wobhedu.

• Imaski yomthengi: Phezu kwe-copper diser yimaski yejoni, enika i-PCB nganye ye-PCB iluhlaza iluhlaza. Izisa i-Copper Pround ikhutshelwe ngaphandle kokudibana nezinye izinto ezisebenzayo ezinokubangela isiphaluka esifutshane. Ngamanye amagama, umthengisi ugcina yonke into ikhona. Imingxunya kwi-Maskr mask kulapho i-joni isetyenziswa khona ukudibanisa icandelo kwiBhodi. Imaski yomthengi linyathelo elibalulekileyo lokwenza imveliso yePCBA egudileyo njengoko kuthintela ukuthengisa kwiindawo ezingafunekiyo kwaye kuthintela imijikelezo emfutshane.

I-Silkscreen: I-Silkscreen emhlophe yindawo yokugqibela kwi-PCB. Lo mthetho wongeza iileyibhile kwi-PCB ngohlobo lweempawu kunye neesimboli. Oku kunceda ukunika isalathiso somsebenzi wecandelo ngalinye ebhodini.

Izibonelelo kunye neempawu zeFr-4.

Ngokubanzi omnye-ngqo-jikelele, iBhodi yeSekethi yePCB ye-PCB yenziwa ngoFr-4, fr kwi-Fr-4 kuthetha ukukhunjulwa idangatye, kwaye inani le-4 liye lahlula izinto ezivela kolu luhlu. Fr-4 yi-ficlass eqinisa i-epobeds e-Epopxy ejongeka ngathi yiphaneli ecekeceke. Ikota kaFr-4 ikwamele iBanga elisetyenziselwa ukwenza la magama. Ulwakhiwo lweFigberglass lubonelela ngokuzinza kwezezixhobo. Ii-fiberglass zee-fiberg zigutyungelwe nge-Eposurment ye-Eposer. Oku kuzisa ukuqina kunye neepropathi zoomatshini omeleleyo kwizinto. Zonke ezi mpawu zenza i-Fr-4 yeebhodi zesekethe eziprintiweyo eziprintiweyo ziphakathi kwabavelisi bezivumelwano ze-elektroniki.

Iimpawu zayo zobuchwephesha zilala ikakhulu: Ukufakwa kombane, ukuSebenza okuZinzileyo, indawo entle, i-fits, i-pits, i-picks, i-PCB yokuSebenzisa i-FPC yokutsalwa, i-PCB iqhuba iBhodi yeFCC, i-fiber yokutsalwa kwe-FPB I-Meshon, i-Pobon yeFobhothi yeFayile yeFayile, iBhodi yePlanethi ichanekile , njl.

Iphepha le-FR-4 lisetyenziswe ngokubanzi kwiimveliso ze-elektroniki ezinjengeshishini, unxibelelwano, ikhompyutha, isiphaluka sedijithali, isiphaluka sedijithali, isiphaluka sezixhobo, kwaye zonke izalathisi zomsebenzi sinokuhlangabezana neemfuno ze-elektroniki yemizi-mveliso. Kukho umyinge wokusebenza kakuhle kakhulu.

Umzekelo: Ibhodi yesekethe yebhetri yebhetri
