PCB bolodi kudula ndizofunikira pakapangidwe ka PCB. Koma chifukwa chimaphatikizapo kugaya sandpaper (ndi ntchito yovulaza), kutsatira mzere (wa ntchito yosavuta yobwerezabwereza), opanga ambiri safuna kuchita nawo ntchitoyi. Ngakhale opanga ambiri amaganiza kuti kudula kwa PCB si ntchito yaukadaulo, opanga mapulani achichepere omwe amaphunzitsidwa pang’ono atha kukhala odziwa ntchitoyi. Lingaliro ili lili paliponse, koma monga ntchito zambiri, pali maluso ena pakucheka kwa PCB. Ngati opanga adziwa maluso awa, amatha kusunga nthawi yambiri ndikuchepetsa kuchuluka kwa ntchito. Tiyeni tikambirane za chidziwitsochi mwatsatanetsatane.

Choyamba, lingaliro la PCB bolodi kudula

Kudulira kwa board ya PCB kumatanthauza njira yopangira zojambula ndi zojambula (PCB zojambula) kuchokera pagulu loyambirira la PCB. Cholinga chake ndikupanga chitukuko chamtsogolo. Kukula kwakanthawi kumaphatikizanso kukhazikitsa kwa zida, kuyesa kwakukulu, kusintha kwa dera, ndi zina zambiri.

Awiri, PCB bolodi kudula ndondomeko

1. Chotsani zida zomwe zili pa bolodi loyambirira.

2. Jambulani bolodi loyambirira kuti mupeze mafayilo azithunzi.

3. Dulani malo osanjikiza kuti mupeze wosanjikiza wapakati.

4. Jambulani wosanjikiza wapakati kuti mupeze fayilo yazithunzi.

5. Bwerezani masitepe 2-4 mpaka magawo onse atakonzedwa.

6. Gwiritsani ntchito mapulogalamu apadera kuti musinthe mafayilo azithunzi kukhala mafayilo amtundu wamagetsi -Zithunzi za PCB. Ndi pulogalamu yoyenera, wopanga amatha kungofufuza graph.

7. Chongani ndi malizitsani mamangidwe.

Atatu, PCB bolodi kudula luso

PCB bolodi kudula makamaka multilayer PCB bolodi kudula ndi ntchito yambiri komanso yotopetsa, yomwe imaphatikizapo kugwira ntchito mobwerezabwereza. Okonza ayenera kukhala oleza mtima komanso osamala mokwanira, apo ayi ndikosavuta kulakwitsa. Chinsinsi chodulira mapangidwe a PCB ndi kugwiritsa ntchito mapulogalamu oyenera m’malo molemba mobwerezabwereza, yomwe ndi nthawi yopulumutsa komanso yolondola.

1. Sikana iyenera kugwiritsidwa ntchito pokonza kachidutswa

Okonza ambiri amagwiritsidwa ntchito kujambula mizere mwachindunji pamakina opanga ma PCB monga PROTEL, PADSOR kapena CAD. Chizolowezi ichi ndi choyipa kwambiri. Mafayilo owonera sikuti ndi maziko okhawo osinthira mafayilo a PCB, komanso maziko oyendera pambuyo pake. Kugwiritsa ntchito makina opangira makina opangira sikani kumatha kuchepetsa zovuta komanso kukula kwa ntchito. Sizokokomeza kunena kuti, ngati sikani ikhoza kugwiritsidwa ntchito mokwanira, ngakhale anthu omwe alibe luso lakapangidwe amatha kumaliza ntchito yodula PCB.

2, umodzi malangizo umapezeka mbale

Mofulumira, ena opanga mapulani amasankha mbale yolowera mbali ziwiri (kutanthauza, kuyambira kutsogolo ndi kumbuyo mpaka pakati). Izi ndizolakwika kwambiri. Chifukwa mbali ziwiri zopera ndizosavuta kuvala, zomwe zimawononga zigawo zina, zotsatira zake zitha kuganiziridwa. Mzere wakunja wa bolodi la PCB ndiwovuta kwambiri ndipo wosanjikiza wapakati ndi wofewa kwambiri chifukwa cha ndondomekoyi ndi zojambulazo zamkuwa ndi pedi. Chifukwa chake pakatikati, vutoli limakhala lalikulu kwambiri ndipo nthawi zambiri silingathe kupukutidwa. Kuphatikiza apo, bolodi ya PCB yopangidwa ndi opanga osiyanasiyana sikofanana pamtundu, kuuma, kukhathamira, ndizovuta kugaya molondola.

3. Sankhani mapulogalamu abwino otembenuka

Kutembenuza mafayilo azithunzi osinthidwa kukhala mafayilo a PCB ndichinsinsi cha ntchito yonse. Muli ndi mafayilo abwino otembenuka. Okonza amangoti “mutsatireni” ndikujambula zojambulazo kamodzi kuti amalize ntchitoyi. EDA2000 ikulimbikitsidwa apa, zomwe ndizosavuta.
