PCB bolodi amagwiritsidwa ntchito kwambiri mu zamagetsi, makompyuta, zida zamagetsi, zida zamakina ndi mafakitale ena. Ndizothandizira zigawo zikuluzikulu ndipo zimagwiritsidwa ntchito makamaka kugwirizanitsa zigawo kuti zipereke magetsi. Pakati pawo, 4-wosanjikiza ndi 6-wosanjikiza matabwa ozungulira ndi ambiri ndi ambiri ntchito. , Milingo yosiyanasiyana ya zigawo za PCB zitha kusankhidwa malinga ndi ntchito zamakampani.

Njira yakuwonongeka kwa board ya PCB:

Njira etching ya bolodi yosindikizidwa nthawi zambiri imamalizidwa mu thanki ya dzimbiri. Zomwe zimagwiritsidwa ntchito ndi ferric chloride. The njira (FeCL3 ndende 30% -40%) ndi wotchipa, ndi dzimbiri anachita liwiro ndi wosakwiya, ndondomeko n’zosavuta kulamulira, ndipo ndi ntchito Kuwononga limodzi ndi awiri amaganiza mkuwa atavala laminates.

Njira yowonongeka nthawi zambiri imapangidwa ndi ferric chloride ndi madzi. Ferric chloride ndi yolimba yachikasu, ndipo ndiyosavuta kuyamwa chinyezi mumlengalenga, motero iyenera kusindikizidwa ndikusungidwa. Pokonzekera njira yothetsera ferric chloride, 40% ferric chloride ndi 60% madzi amagwiritsidwa ntchito, ndithudi, ferric chloride, kapena madzi ofunda (osati madzi otentha kuti ateteze utoto kuti asagwe) angapangitse kuti ferric chloride isagwe. ndi zowononga. Yesetsani kuti musakhudze khungu lanu ndi zovala zanu. Gwiritsani ntchito beseni lapulasitiki lotsika mtengo lachotengeracho, ingokwanira bolodi yozungulira.

Yambani dzimbiri PCB dera bolodi kuchokera m’mphepete. Pamene zojambulazo za mkuwa zosapentidwa zawonongeka, bolodi la dera liyenera kuchotsedwa nthawi yake kuti penti zisawonongeke mabwalo othandiza. Panthawiyi, tsukani ndi madzi oyera, ndikuchotsani utoto ndi tchipisi tansungwi mwa njira (panthawiyi, utoto umatuluka mumadzimadzi ndipo umakhala wosavuta kuchotsa). Ngati sichapafupi kukanda, ingotsukani ndi madzi otentha. Kenako pukutani ndi kupukuta ndi sandpaper, kuwululira zojambulazo zonyezimira zamkuwa, ndipo bolodi losindikizidwa lakonzeka.

Pambuyo pa bolodi losindikizidwa lawonongeka, chithandizo chotsatirachi chiyenera kuchitidwa pambuyo poti gulu losindikizidwa lawonongeka.

1. Pambuyo pochotsa filimuyo, bolodi losindikizidwa losindikizidwa lomwe latsuka ndi madzi oyera limanyowa m’madzi otentha kwa nthawi ndithu, ndiyeno filimu yophimbidwa (pasted) ikhoza kuchotsedwa. Malo osapukutidwa amatha kutsukidwa ndi woonda kwambiri mpaka atayera.

2. Chotsani filimu ya okusayidi. Pamene filimu yophimbidwa (yoikidwa) imachotsedwa, pambuyo pa bolodi losindikizidwa losindikizidwa, pukutani bolodi mobwerezabwereza ndi nsalu yoviikidwa mu ufa wa decontamination kuti muchotse filimu ya oxide pa zojambula zamkuwa, kuti dera losindikizidwa ndi soldering The bright mtundu wamkuwa umawonekera pa disk.

Tiyenera kuzindikira kuti popukuta zojambulazo zamkuwa ndi nsalu, ziyenera kufufuzidwa motsatira njira yokhazikika kuti zojambulazo ziwonetsedwe mofanana, zomwe zimawoneka zokongola kwambiri. Muzimutsuka bolodi losindikizidwa lopukutidwa ndi madzi ndikuwumitsa.

3. Kugwiritsa ntchito flux Kuti muthe kuyendetsa soldering, onetsetsani kuti ma conductivity a bolodi losindikizidwa losindikizidwa ndi kupewa dzimbiri, gulu la dera losindikizidwa litatha, chingwe cha flux chiyenera kugwiritsidwa ntchito pazitsulo zamkuwa za bolodi losindikizidwa kuti muteteze mpweya.
