mmene kupanga iwiri mbali pcb kunyumba

Pamagetsi, bolodi losindikizidwa (PCB) ndiye msana wa zida zambiri zamagetsi.Ngakhale kupanga ma PCB apamwamba nthawi zambiri kumachitidwa ndi akatswiri, kupanga ma PCB a mbali ziwiri kunyumba kungakhale njira yotsika mtengo komanso yothandiza nthawi zina.Mubulogu iyi, tikambirana njira yaposachedwa yopangira PCB yokhala ndi mbali ziwiri m'nyumba mwanu.

1. Sonkhanitsani zofunikira:
Musanayambe kudumphira pakupanga, ndikofunikira kusonkhanitsa zida zonse zofunika.Izi zikuphatikizapo laminates copper-clad, zolembera zokhazikika, makina osindikizira a laser, ferric chloride, acetone, zobowola, waya wokutidwa ndi mkuwa, ndi zipangizo zotetezera monga magolovesi ndi magalasi.

2. Konzani masanjidwe a PCB:
Pogwiritsa ntchito mapulogalamu a PCB, pangani dongosolo lamagetsi omwe mukufuna kupanga.Chiwembu chikatha, pangani masanjidwe a PCB, kuyika magawo osiyanasiyana ndi mawonekedwe ngati pakufunika.Onetsetsani kuti masanjidwewo ndi oyenera PCB ya mbali ziwiri.

3. Sindikizani mawonekedwe a PCB:
Sindikizani mawonekedwe a PCB papepala lonyezimira pogwiritsa ntchito chosindikizira cha laser.Onetsetsani kuti mwayang'ana chithunzicho mopingasa kuti chisamukire ku bolodi lovala zamkuwa.

4. Masanjidwe otumizira:
Dulani mawonekedwe osindikizidwa ndikuyika pansi pa bolodi lovala zamkuwa.Chitetezeni pamalo ake ndi tepi ndikuwotcha ndi chitsulo pa kutentha kwakukulu.Kanikizani mwamphamvu kwa mphindi pafupifupi 10 kuti muwonetsetse kugawa kwa kutentha.Izi zidzasamutsa inki kuchokera papepala kupita ku mbale yamkuwa.

5. Kuyika mbale:
Chotsani mosamala pepalalo pa bolodi lovala zamkuwa.Tsopano muwona mawonekedwe a PCB atasamutsidwa kumtunda wamkuwa.Thirani ferric chloride yokwanira mu pulasitiki kapena chidebe chagalasi.Lumikizani bolodi mu ferric chloride solution, kuonetsetsa kuti yatsekedwa kwathunthu.Pang'onopang'ono yambitsani njira yofulumizitsa etching.Kumbukirani kuvala magolovesi ndi magalasi panthawiyi.

6. Yeretsani ndi kuyang'ana bolodi yozungulira:
Pambuyo pa etching ndondomeko yatha, bolodi imachotsedwa mu yankho ndikutsuka ndi madzi ozizira.Chepetsani m'mbali ndikupukuta bolodilo ndi siponji kuti muchotse inki yochulukirapo ndi zotsalira.Yamitsani bolodi kwathunthu ndikuwunika zolakwika kapena zovuta zilizonse.

7. Kubowola:
Pogwiritsa ntchito kubowola ndi pang'ono pokha, mosamala kubowola mabowo pa PCB pa malo osankhidwa kwa chigawo makhazikitsidwe ndi soldering.Onetsetsani kuti dzenjelo ndi loyera komanso lopanda zinyalala zamkuwa.

8. Zida zowotcherera:
Ikani zida zamagetsi kumbali zonse za PCB ndikuziteteza ndi tatifupi.Gwiritsani ntchito chitsulo chosungunula ndi waya wa solder kuti mugwirizane ndi zigawozo ndizitsulo zamkuwa.Tengani nthawi yanu ndikuwonetsetsa kuti ma solder ndi oyera komanso olimba.

Pomaliza:
Potsatira malangizo awa tsatane-tsatane, mukhoza bwinobwino kupanga iwiri-mbali PCB kunyumba.Ngakhale kuti ndondomekoyi poyamba ingaphatikizepo kuyesa ndi zolakwika, ndikuchita komanso kusamala mwatsatanetsatane, mukhoza kupeza zotsatira za akatswiri.Kumbukirani kuti nthawi zonse muziika chitetezo patsogolo, valani zida zoyenera zodzitchinjiriza ndikugwira ntchito pamalo olowera mpweya wabwino.Chifukwa chake tsegulani luso lanu ndikuyamba kupanga ma PCB anuawiri!
