Mzere wamkuwa wa bolodi losindikizidwa ndiye cholinga cha kapangidwe ka dera lililonse, zigawo zina zimangothandiza kapena kuteteza madera, kapena kusintha njira yamsonkhano. Kwa Wopanga PCB yemwe akutukuka, cholinga chachikulu ndikungopeza kulumikizana kuchokera pa malo A mpaka B ndi mavuto ochepa momwe angathere.

Chingwe chamkuwa cha bolodi losindikizidwa ndichomwe chimayang’aniridwa ndi kapangidwe ka dera lililonse, zigawo zina zimangothandiza kapena kuteteza dera, kapena kuchepetsa msonkhano. Kwa Wopanga PCB yemwe akutukuka, cholinga chachikulu ndikungopeza kulumikizana kuchokera pa malo A mpaka B ndi mavuto ochepa momwe angathere.

Komabe, ndi nthawi ndi luso, opanga ma PCB amayang’ana kwambiri pa:

kufotokozera

zojambulajambula

Kugwiritsa ntchito malo

Ntchito yonse

Bokosi lotsika mtengo

Kupezeka kumabwera chifukwa cha liwiro ndi mtundu

PCB Yokha

Nthawi zambiri zimafala chifukwa chakusintha kwakanthawi

Professional PCB

Gwiritsani ntchito njira zapamwamba kwambiri kuti musinthe magwiridwe ake ntchito ndi kulolerana

L Gwiritsani ntchito njira zopangira etching ndi zida zabwinoko ndi ukatswiri

Chifukwa cha kuthekera kwakukulu kwa ukadaulo, kusiyana pakati pamakomiti amateur ndi akatswiri kudayamba kuwonekera kwambiri pomwe kulolerana kumakulirakulira

Kusiyanitsa pakati pa nyumba zotsika mtengo ndi zabwino kwaonekeranso

Masitepe PCB etching:

1. Mofanana ndi kuyika chithunziresist pachikopa chovekedwa ndi mkuwa

Photoresist imazindikira kuwala kwa ultraviolet ndipo imawumitsa pambuyo powonekera. Wojambula zithunzi ndiye amaphimbidwa ndi chithunzi cholimba chamkuwa m’mbale.

2. Kuwala kwamphamvu kwa ultraviolet kumagwiritsidwa ntchito kuwulula chivundikiro chapansi cha bolodi lazungulira

Kuwala kwamphamvu kwa ultraviolet kumalimbitsa madera omwe amayenera kutsalira mbale zamkuwa. Tekinolojeyi ndiyofanana ndi yomwe imagwiritsidwa ntchito popanga ma semiconductors okhala ndi ma nanometer makumi, kukula kwake, motero imatha kukhala ndi mawonekedwe abwino.

3. Kumiza bolodi lonselo mu yankho lochotsa chithunzi cholimbikira

4. Gwiritsani ntchito chopangira mkuwa kuti muchotse mkuwa wosafunikira

Vuto losangalatsa pamtengo wofunikira ndikufunika kupanga anisotropic etching. Mkuwawo utakhazikika pansi, m’mphepete mwake mwa mkuwa wotetezedwayo umawululidwa ndikusiya wopanda chitetezo. Kutsalako kukhale kocheperako, kumakhala kocheperako poyerekeza ndi gawo lotetezedwa kumtunda wosanjikiza.

5. Kubowola mabowo mu PCB

Kuyambira kukulira kudzera m’mabowo mpaka kubowo lokwera, mabowo awa amatha kugwiritsidwa ntchito zosiyanasiyana mu PCB. Mabowo amenewa akangopangidwa, mkuwa umayikidwa m’makoma a dzenje pogwiritsa ntchito mkuwa wosagwiritsa ntchito magetsi kuti apange kulumikizana kwamagetsi kudera lonselo.

Njira zopangira ndi kapangidwe ka PCB sizinganyalanyazidwe kapena sizinganyalanyazidwe. Ngakhale wopanga safuna zaka zakapangidwe ka PCB ndi zokumana nazo pamisonkhano, kumvetsetsa kwamomwe mungapangire zinthu izi kumakupatsani chidziwitso chakumveka bwino komanso chifukwa chake kapangidwe kabwino ka PCB kamagwira ntchito.
