PCBA ndi chidule cha kusindikizidwa gulu gulu msonkhano mu English, ndiko kunena kuti, chopanda PCB akudutsa SMT Mumakonda kapena ndondomeko kuviika pulagi-mu, amene amatchedwa PCBA mwachidule Iyi ndi ambiri ntchito kulemba njira ku China, pomwe njira yodziwika bwino yolembera ku Europe ndi America ndi pcb’a yokhala ndi “’”, yomwe imatchedwa chilankhulidwe chovomerezeka. Utali wotani ndi uwu PCBA processing mankhwala akhoza kusungidwa.
Zinthu zosinthidwa za PCBA zitha kusungidwa nthawi yayitali bwanji.

PCBA amatanthauza bolodi dera ndi zigawo zosiyanasiyana welded pamwamba pake. Anthu nthawi zambiri amalabadira kudalirika kwake kwa nthawi yayitali komanso yothamanga kwambiri, ndipo nthawi zina amafunika kudziwa moyo wake wa alumali. Nthawi zambiri, moyo wosungira wa zinthu zopangidwa ndi PCBA ndi zaka 2-10, zomwe zimakhudzidwa kwambiri ndi izi:
1. Zachilengedwe
Malo achinyezi ndi fumbi mwachiwonekere sakuyenera kusungidwa kwa PCBA. Zinthu izi imathandizira makutidwe ndi okosijeni ndi dothi wa PCBA ndi kufupikitsa alumali moyo wa PCBA. Nthawi zambiri, tikulimbikitsidwa kusunga PCBA pamalo owuma, opanda fumbi ndi kutentha kosalekeza kwa 25 ℃.
2. Kudalirika kwa zigawo
Kudalirika kwa zigawo ndi mbali pa PCBAs osiyana komanso kwambiri chimatsimikizira alumali moyo wa PCBA. Zigawo ndi mbali ndi zipangizo apamwamba ndi njira ndi luso kukana chilengedwe nkhanza, ndi lonse la mphamvu ndi wamphamvu makutidwe ndi okosijeni kukana, amenenso amapereka chitsimikizo kwa bata la PCBA.
3. Njira yochizira zinthu ndi pamwamba pa bolodi ladera
Zida za bolodi lokhalokha sizimakhudzidwa mosavuta ndi chilengedwe, koma njira yake yothandizira pamwamba imakhudzidwa kwambiri ndi okosijeni wa mpweya. Chithandizo chabwino chapamwamba chimatha kutalikitsa moyo wa alumali wa PCBA.
4. PCBA bolodi kuthamanga katundu
PCBA ntchito katundu ndi chinthu chofunika kwambiri kwa moyo wake yosungirako. Opaleshoni ndi mkulu pafupipafupi ndi mkulu katundu adzakhala mosalekeza mkulu zimakhudza dera bolodi mizere ndi zigawo zikuluzikulu, amene adzakhala kosavuta oxidize mchikakamizo cha Kutentha, chifukwa cha dera lalifupi ndi lotseguka dera pa ntchito yaitali. Choncho, magawo ntchito ya bolodi PCBA ayenera kukhala mkati osiyanasiyana a zigawo zikuluzikulu ndi kupewa kukhala pafupi ndi nsonga mtengo, amene angathe kuteteza PCBA ndi kuwonjezera moyo wake yosungirako.
Alumali moyo wa mankhwala PCBA kukonzedwa ndi ntchito mabuku, amene ayenera kutsatira mfundo kamangidwe ka sayansi, specifications kupanga ndondomeko ndi specifications ntchito, kuti azipeza alumali moyo.
Zomwe zili pamwambazi ndizofotokozera ndi zinthu zomwe zingasungidwe PCBA pokonza zinthu. Ndikukhulupirira kuti ikhoza kukuthandizani.

Tsopano pali zida zambiri zamagetsi, malinga ngati zinthu zomwe zingagwiritsidwe ntchito zimafunikira PCB, opanga ambiri opanga zinthu zamagetsi sadziwa momwe angalipire PCBA processing. PCBA processing ndalama amapangidwa ndi zimenezo.
PCBA chigamba processing mtengo kupanga
1. Ndalama za PCB (ngati mutazipereka nokha, sizidzaperekedwa);
2. chindapusa chogulira (ngati muperekanso izi nokha, zilinso zaulere);
3. SMT pokonza ndalama (SMD chip + dip positi kuwotcherera);
4. Malipiro a mayeso a PCBA ndi malipiro a msonkhano.
Mtengo wowerengera wa PCBA patch processing
1, PCB board amalipiritsa
Ngati mukufuna kupeza PCBA purosesa kukuthandizani pokonza, muyenera kupereka PCB owona ndi BOM mndandanda. Purosesa ya PCBA idzakuthandizani kupanga matabwa a PCB molingana ndi mafayilo anu a PCB. Panthawiyi, gawo loyamba la mtengo, malipiro a bolodi la PCB, lidzaperekedwa. Mtengo wa bolodi PCB zimadalira ndondomeko zovuta gulu. Mwachitsanzo, mitengo ya 4-wosanjikiza bolodi, 8-wosanjikiza bolodi, zotayidwa gawo lapansi ndi carbon inki bolodi ndi osiyana. Kumene, mukhoza kupeza PCBA bolodi fakitale kwa processing. Mtengo wake siwotsika mtengo. Kupatula apo, payenera kukhala kuchotsera kwa mgwirizano wanthawi yayitali wa ena. Chonde khalani omasuka kukhala wankhanza mdera lanu.
2, chigawo mtengo wogula
PCBA chigamba processing gawo II mtengo, chigawo mtengo kugula. Wopanga makina amagula zigawo ndi magawo omwe mukufuna malinga ndi BOM. Pogula zigawo ndi zigawo, chifukwa cha disk loading monga resistors ndi capacitors ndi SMT chip imfa (monga kulumpha bolodi molakwika, osati kuchotsa koyilo tepi mu nthawi, etc.), pafupifupi 5% ya kutaya zinthu ayenera kuphimbidwa; Opanga amakhala ndi mgwirizano wautali ndi opanga zigawo, kotero mtengo udzakhala wotsika.
3, chindapusa cha SMT (SMD chip + dip post kuwotcherera)
Powerengera ndalama zolipirira za SMT, choyamba muyenera kuwona kukula kwake. Ngati ndi yayikulu kuposa 2000pic, palibe chifukwa cholipiritsa chindapusa cha uinjiniya, apo ayi padzakhala ndalama zowonjezera zaukadaulo. Kenaka, werengerani chiwerengero cha mfundo zochulukitsidwa ndi mtengo wamtengo wapatali wa mfundo. Mtengo wapatch point uli pakati pa 0.01-0.015 yuan. Chiwerengero cha mfundo chimawerengedwa molingana ndi ma pin awiri a SMT patch material ndi pini imodzi ya dip plug-in. Chulukitsani ziwirizo. Kuwongolera kungagawidwe mu:
Chigawo cha 1.0402 chimawerengedwa ngati 0.015 pa dothi * ndalama 0603-1206 zigawo zimawerengedwa ndi 0.015 pa mfundo * ndalama
2. pini imodzi ya pulagi-mu zakuthupi ndi mfundo; Imawerengedwa ngati 0.015 pa point * ndalama.
3. mapini anayi amtundu wa slot ndi mfundo imodzi; Imawerengedwa ngati 0.015 pa point * ndalama.
4. wamba IC, mapini 4 ndi mfundo imodzi; Imawerengedwa ngati 1 pa point * ndalama.
5. wandiweyani pini IC, mapini awiri ndi mfundo imodzi; Imawerengedwa ngati 0.015 pa point * ndalama.
6. miyendo iwiri ya BGA ndi mfundo imodzi; Imawerengedwa ngati 0.015 pa point * ndalama.
7. makina opakidwa zinthu zambiri adzawerengedwa ndi kuwirikiza kawiri kuchuluka kwa zigawo.
8. ndalama zowonjezera zimawerengedwa ngati 20 yuan * pa ola limodzi
9. mawuwo samaphatikizapo chindapusa choyesa, chindapusa, msonkho, ndi zina.
4, chindapusa cha mayeso a PCBA ndi chindapusa cha msonkhano
Ndalama zoyeserera za PCBA nthawi zambiri zimawerengedwa kuti ndi 2 yuan pa mbale, kuphatikiza mtengo wa PCBA wophatikizira ndi kuyika, womwe nthawi zambiri ndi 0.8 yuan pa mbale. Ili ndi gawo lachinayi la malipiro.
Onjezani magawo anayi omwe ali pamwambawa amtengo, womwe ndi mtengo wopangira chigamba cha PCBA.
Pamwambapa ndi momwe kulipira kwa PCBA chigamba processing? Kuyamba kwa zikuchokera PCBA chigamba processing ndalama, ine ndikuyembekeza kungakuthandizeni, ndipo ine ndikufuna kudziwa zambiri za PCBA pokonza zambiri.
