Ndiyakholwa ukuba abantu abaninzi abaqhelananga neebhodi zesekethe PCB, kwaye unokuviwa rhoqo kubomi bemihla ngemihla, kodwa basenokungazi kakhulu malunga PCBA, kwaye basenokubhidaniswa PCB.Ke yintoni iPCB?I-PCBA yavela njani?Yintoni umahluko phakathi kwePCB kunye nePCBA?Makhe sihlolisise.
Malunga PCB
I-PCB sisishunqulelo seBhodi yeSekethe eShicileleyo, eguqulelwe kwisiTshayina ibizwa ngokuba yibhodi yesekethe eprintiweyo, kuba yenziwa ngoshicilelo lwe-elektroniki, ibizwa ngokuba "yibhodi yesekethe eprintiweyo".I-PCB licandelo le-elektroniki elibalulekileyo kushishino lwe-elektroniki, inkxaso yamacandelo e-elektroniki, kunye nomphathiswa woqhagamshelo lombane lwamacandelo e-elektroniki.I-PCB isetyenziswe ngokubanzi kakhulu ekwenzeni iimveliso zombane.Iimpawu ezizodwa zePCB zishwankathelwa ngolu hlobo lulandelayo:
1. Ubuninzi be-wiring ephezulu, ubungakanani obuncinci kunye nobunzima obulula, obufanelekileyo kwi-miniaturization yezixhobo zombane.
2. Ngenxa yokuphindaphinda kunye nokuhambelana kwemizobo, iimpazamo kwi-wiring kunye nendibano ziyancitshiswa, kunye nokugcinwa kwezixhobo, ukulungiswa kunye nexesha lokuhlola ligcinwa.
3. Kukulungele umatshini kunye nokuveliswa ngokuzenzekelayo, okuphucula imveliso yabasebenzi kunye nokunciphisa iindleko zezixhobo zombane.
4. Uyilo lunokulungelelaniswa ukuze luququzelele ukuguquguquka.
MalungaPCBA
I-PCBA sisishunqulelo seBhodi yeSekethe eShicileleyo + neNdibano, nto leyo ethetha ukuba i-PCBA idlula kuyo yonke inkqubo yokwenziwa kwe-PCB engenanto yebhodi ye-SMT kwaye emva koko i-plug-in ye-DIP.
Qaphela: Zombini i-SMT kunye ne-DIP ziindlela zokudibanisa iindawo kwi-PCB.Umahluko omkhulu kukuba i-SMT ayifuni gqobhoza imingxuma kwi-PCB.Kwi-DIP, izikhonkwane ze-PIN zamacandelo kufuneka zifakwe kwimingxuma egrunjiweyo.
I-SMT (i-Surface Mounted Technology) itekhnoloji yokuxhoma umphezulu ikakhulu isebenzisa izixhomi ukuxhoma iindawo ezincinci kwi-PCB.Inkqubo yemveliso yile: PCB board positioning, solder paste printing, mounting mounting, kunye reflow Furnace kunye nokuhlolwa okugqityiweyo.
I-DIP ithetha "iplagi-in", oko kukuthi, ukufaka iinxalenye kwibhodi yePCB.Oku kukuhlanganiswa kwamacandelo ngendlela yeeplagi-in xa ezinye iindawo zikhulu ngobukhulu kwaye azifanelekanga kwiteknoloji yokubeka.Eyona nkqubo iphambili yemveliso yile: ukuncamathelisa okuncamathelayo, iplagi-in, uhlolo, i-wave soldering, ukuprintwa kunye nokuhlolwa okugqityiweyo.
*Umahluko phakathi kwePCB kunye nePCBA*
Ukususela kwintshayelelo engentla, siyakwazi ukuba i-PCBA ibhekisela ngokubanzi kwinkqubo yokucubungula, enokuthi iqondwe njengebhodi yesekethe egqityiweyo, oku kuthetha ukuba i-PCBA ingabalwa kuphela emva kokuba iinkqubo zebhodi ye-PCB zigqityiwe.I-PCB ibhekisa kwibhodi yesekethe engenanto eprintiweyo engenazo iindawo kuyo.
Ngokubanzi: I-PCBA yibhodi egqityiweyo;I-PCB yibhodi engenanto.
