mmene kupanga pcb dera

A PCB (Printed Circuit Board) ndiye maziko a zida zamagetsi, kulola kulumikizana ndikuyenda kwa magetsi pakati pa magawo osiyanasiyana.Kaya ndinu katswiri wazokonda zamagetsi kapena katswiri, kudziwa kupanga mabwalo a PCB ndi luso lofunikira lomwe lingalimbikitse mapulojekiti anu aukadaulo.Mu blog iyi, tipereka kalozera wagawo ndi sitepe wamomwe mungapangire dera la PCB.

1. Kupanga ndi kupanga masinthidwe:

Gawo loyamba pakupanga dera la PCB ndikupanga ndi kupanga schema.Pogwiritsa ntchito pulogalamu yopangira schema, monga Eagle kapena KiCad, jambulani chithunzi chozungulira.Kuyika mosamala kwa zigawo, kuyika bwino kwambiri komwe kumatsimikizira kuyenda kwa ma sigino ndi njira yabwino ndikofunikira.

2. Kapangidwe ka PCB:

Chiwembu chikatha, sitepe yotsatira ndikupanga masanjidwe a PCB.Izi zimaphatikizapo kusamutsa zigawo ndi zolumikizira kuchokera ku schema kupita ku kapangidwe ka bolodi.Gwirizanitsani zigawo ndi mapaketi awo, kuwonetsetsa kuti zikuyenda bwino ndikusunga malo oyenera kuti musasokonezedwe.

3. Kuyika mbale:

Pamene PCB masanjidwe wathunthu, ndi nthawi etch bolodi.Choyamba sindikizani mapangidwe a board board papepala lapadera losinthira pogwiritsa ntchito chosindikizira cha laser.Ikani chosindikizira pa PCB yamkuwa ndikuwotcha ndi chitsulo kapena laminator.Kutentha kumasamutsa inki kuchokera papepala kupita ku bolodi, kupanga chophimba chotetezera pazitsulo zamkuwa.

4. Njira yolumikizira:

Kusamutsa kwatha, ndi nthawi yoti muyike bolodi.Konzani chidebe chokhala ndi njira yoyenera yolumikizira (monga ferric chloride) ndikuviikamo bolodi.Pang'onopang'ono yambitsani njira yothetsera kuchotsa mkuwa wochuluka kuchokera kumadera osatetezedwa, ndikusiya zizindikiro zomwe mukufuna.Panthawiyi, onetsetsani kuti mukutsatira njira zodzitetezera monga kuvala magolovesi ndi magalasi, chifukwa njira yothetsera vutoli ikhoza kukhala yoopsa.

5. Kubowola:

Pambuyo pa etching, mabowo amafunika kubowola kuti aike zigawo zake.Gwiritsani ntchito kubowola ndi kachidutswa kakang'ono komwe kamafanana ndi kukula kwa chigawocho.Boolani mosamala magawo omwe mwasankhidwa ndikuwonetsetsa kuti mabowowo ndi aukhondo komanso opanda zinyalala.

6. Kuwotcherera:

Pambuyo bolodi wakhala anazikika ndi mabowo mokhomerera, ndi nthawi solder zigawo zikuluzikulu pa PCB.Yambani ndikulumikiza zigawozo m'mabowo ake, kuonetsetsa kuti zakhala bwino.Tembenuzani bolodi ndikugulitsa chigawo chilichonse, kugwiritsa ntchito kutentha kusungunula waya wa solder ndikupanga mgwirizano wamphamvu.Gwiritsani ntchito chitsulo chosungunula chabwino komanso chotuluka kuti mukwaniritse zolumikizira zoyera komanso zodalirika.

7. Mayeso:

Pambuyo pa soldering zigawo zonse, ntchito ya dera iyenera kuyesedwa.Gwiritsani ntchito ma multimeter kuti muwone kupitiliza ndikutsimikizira kulumikizana koyenera.Komanso, yang'anani zowona kuti muwonetsetse kuti palibe milatho ya solder kapena malo ozizira.

Pomaliza:

Kupanga mabwalo a PCB kungawoneke ngati kovuta poyamba, koma ndi chidziwitso choyenera ndi zida, zitha kukhala ntchito yotheka.Potsatira kalozera wa tsatane-tsatane woperekedwa mubulogu iyi, mutha kupanga mabwalo a PCB molimba mtima pama projekiti anu amagetsi.Kumbukirani, kuchita masewera olimbitsa thupi kumapangitsa kukhala kwangwiro, kotero musataye mtima ngati zimatenga zoyesayesa zingapo kuti mumvetsere.Ndi nthawi ndi zinachitikira, mudzatha kupanga bwinobwino zovuta ndi mkulu-ntchito mabwalo PCB.
