Momwe mungapezere dzenje lakhungu mu bolodi la PCB?Pazinthu zopanga zamagetsi, PCB (Pulogalamu Yosindikizidwa ya Circuit Board, bolodi losindikizidwa) imagwira ntchito yofunika kwambiri, imagwirizanitsa ndikuthandizira zipangizo zosiyanasiyana zamagetsi, kuti zipangizo zamagetsi zigwire ntchito bwino.Mabowo akhungu ndi chinthu chodziwika bwino pakupanga kwa PCB kuti alumikizane ndi mabwalo osiyanasiyana, koma nthawi zambiri amakhala ovuta kupeza ndikuwunika.Nkhaniyi ifotokoza mmene bwino kupeza mabowo akhungu PCB matabwa kuonetsetsa khalidwe ndi kudalirika kwa bolodi.
1. Gwiritsani ntchito njira zowunikira maso
Momwe mungapezere dzenje lakhungu mu bolodi la PCB?Kuwunika kwa kuwala ndi njira yodziwika bwino yomwe imagwiritsidwa ntchito popeza mabowo akhungu m'ma board a PCB.Pogwiritsa ntchito maikulosikopu yokwera kwambiri, akatswiri amatha kuyang'ana kwambiri pa PCB pamwamba pa mabowo omwe angathe.Pofuna kuwonetsetsa bwino, gwero lapadera la kuwala, monga kuwala kwa ultraviolet, lingagwiritsidwe ntchito kuthandizira kuzindikira malo a dzenje lakhungu.
Kuonjezera apo, ma microscopes a digito ndi makamera apamwamba angagwiritsidwe ntchito kusunga zowonera mu mawonekedwe a digito kuti afufuze ndi kujambula.Njirayi ndiyoyenera kupanga magulu ang'onoang'ono komanso magawo a kafukufuku ndi chitukuko, koma imatha kutenga nthawi komanso kuvutikira pakupanga kwakukulu.
2. Gwiritsani ntchito kuzindikira kwa X-ray
X-ray kuyendera ndi njira yamphamvu kwambiri yomwe ingagwiritsidwe ntchito kupeza mabowo akhungu okwiriridwa m'mabodi a PCB.Imazindikira malo a dzenje lakhungu powunikira bolodi la PCB ndikujambula chithunzi cha X-ray.Chifukwa cha kuloŵa kwa X-ray, n’zotheka kuzindikira mabowo akuya osati pamwamba chabe.
Kuwunika kwa X-ray ndikwabwino kwambiri komanso koyenera kumalo opangira zinthu zazikulu.Komabe, pamafunika zida ndi maphunziro a ogwira ntchito odziwa zambiri, kotero pakhoza kukhala zolepheretsa malinga ndi mtengo ndi zofunikira zaukadaulo.
3. Gwiritsani ntchito luso lozindikira kutentha
Ukadaulo wodziwikiratu kutentha ndi njira yogwiritsira ntchito zowunikira kutentha kuti mupeze mabowo akhungu okwiriridwa m'mabodi a PCB.Mwa njira iyi, kupezeka kwa kuyatsa kwakhungu kumatha kudziwika mwa kuyika gwero la kutentha kumbali imodzi ya bolodi la PCB ndikuwunika kusintha kwa kutentha mbali inayo.Chifukwa kuikidwa m'manda akhungu kumakhudza kuyendetsa kutentha, kumasonyeza kuyankha kosiyanasiyana kwa kutentha panthawi yozindikira.
Momwe mungapezere dzenje lakhungu mu bolodi la PCB?Kusankha njira yoyenera kumadalira kukula kwa kupanga, bajeti ndi zofunikira zaukadaulo.Ziribe kanthu njira ntchito, m'pofunika kuonetsetsa khalidwe ndi kudalirika kwa bolodi PCB kukwaniritsa zofunika zida zamagetsi.Pakupanga kwa PCB, kusaka kwabwino kwa mabowo akhungu ndikofunikira kuti muwonetsetse kuti gulu ladera likuyenda bwino komanso lodalirika.
