Gawo la PCB palokha limapangidwa ndi zinthu zomwe zimasungidwa ndipo zimatsutsana ndi kupindika. Zida zazing’ono zomwe zimawoneka pamtunda ndizithunzi zamkuwa. Poyamba, zojambulazo zamkuwa zimaphimbidwa pa bolodi lonse la PCB, koma gawo lapakati limakhazikika pakupanga, ndipo gawo lotsalira limakhala maulamuliro a madera ang’onoang’ono.

Momwe mungapangire PCB Board

Mizere imeneyi imatchedwa oyendetsa kapena wiring ndipo amagwiritsidwa ntchito popereka kulumikizana kwamagetsi pakati pazigawo za PCB. Kawirikawiri mtundu wa bolodi PCB ndi wobiriwira kapena bulauni, ndilo mtundu wa solder kukana utoto. Kutchinjiriza kotchinjiriza komwe kumateteza waya wamkuwa ndikulepheretsa magawo kuti azimangirizidwa kumalo olakwika.

Kupanga kwa PCB kumayambira ndi “gawo lapansi” lopangidwa ndi Glass Epoxy kapena zida zofananira. Gawo loyamba ndikutenga chithunzi pakati pa magawo mwa “kusindikiza” zoyipa za bolodi ya PCB yolumikizira cholumikizira chachitsulo pogwiritsa ntchito njira yochotsera.

Chinyengo ndikufalitsa zojambulazo zazitsulo zamkuwa pamwamba pake ndikuchotsa zochulukirapo. Ngati mukupanga PCB yamagulu awiri, zojambulazo zamkuwa zidzaphimba mbali zonse ziwiri za gawo lapansi. Ndipo ndikufuna kuchita bolodi yama multilayer kuti ndikwanitse kupanga mbale ziwiri zapawiri zokhala ndi zomata zomata “press close” kuwuka kunapita.

Kenako, kuboola ndi plating zofunika kuti pulagi mu zigawo zikhoza kuchitika pa bolodi PCB. Pambuyo pokhomedwa ndi makina momwe amafunira, mabowo amayenera kukulungidwa mkati (yokutidwa ndi Tekinoloje yaukadaulo, PTH). Pambuyo popanga chitsulo mkati mwa bowo, mizere yamkati yazingwe iliyonse imatha kulumikizidwa.

Mabowo ayenera kutsukidwa ndi zinyalala asanayambe kuyala. Izi ndichifukwa choti utomoni wa epoxy umatulutsa kusintha kwamankhwala mukatenthetsa, ndipo umaphimba mkati mwa PCB, chifukwa chake uyenera kuchotsedwa kaye. Kuyeretsa ndi kuyeretsa kumachitika mothandizidwa ndi mankhwala. Chotsatira, muyenera kuphimba zingwe zakunja ndi penti ya solder (inki ya solder) kuti zingwezo zisakhudze gawo lolumikizana.

Zolemba zosiyanasiyana zimasindikizidwa pa bolodi loyang’anira posonyeza komwe gawo lirilonse lili. Sayenera kuphimbidwa ndi kachingwe kapena golide aliyense, apo ayi imatha kuchepetsa kusungika kapena kukhazikika kwa kulumikizana kwamakono. Kuphatikiza apo, ngati pali kulumikizana kwazitsulo, gawo la “chala” limakhala lokutidwa ndi golide kuti liwonetsetse kulumikizana kwapamwamba kwambiri pakulowetsedwa muzowonjezera.

Pomaliza, pali mayeso. Kuyesa PCB kwakanthawi kochepa kapena dera lotseguka, kuyesa kwamagetsi kapena kwamagetsi kungagwiritsidwe ntchito. Mayeso owoneka bwino amagwiritsa ntchito sikani kuti apeze zolakwika m’magawo, pomwe mayeso amagetsi amagwiritsa ntchito chowunikira kuti awone kulumikizana konse. Kuyesa kwamagetsi kumakhala kolondola kwambiri pakupeza maseketi afupipafupi kapena zopuma, koma kuyesa kwamawonekedwe kumatha kuzindikira mosavuta zovuta ndi mipata yolakwika pakati pa oyendetsa.
