Kodi pali kusiyana kotani pakati pa matabwa a PCB amitundu yosiyanasiyana

TheZithunzi za PCBnthawi zambiri timawona ali ndi mitundu yambiri.M'malo mwake, mitundu iyi imapangidwa ndi kusindikiza inki zosiyanasiyana za PCB solder.Mitundu Common mu PCB dera bolodi solder kukana inki ndi wobiriwira, wakuda, wofiira, buluu, woyera, wachikasu, etc. Anthu ambiri chidwi, pali kusiyana kotani pakati pa matabwa dera mitundu yosiyanasiyana?
Kaya ndi bolodi yozungulira pa chipangizo chamagetsi, bolodi ya foni yam'manja kapena bolodi yamakompyuta, onse amagwiritsa ntchito ma board a PCB.Kuchokera pamawonekedwe, matabwa a PCB ali ndi mitundu yosiyanasiyana, zobiriwira ndizofala, zotsatiridwa ndi buluu, zofiira, zakuda, zoyera ndi zina zotero.
Mabodi okhala ndi gawo lomwelo ali ndi ntchito yofanana mosasamala kanthu za mtundu wanji.Ma board amitundu yosiyanasiyana amawonetsa mitundu yosiyanasiyana ya inki yokanira yogwiritsidwa ntchito.Ntchito yaikulu ya solder kukana inki ndikuyiyika pa solder resist layer kuti iphimbe mawaya otsekemera komanso kupewa maulendo afupikitsa.Green nthawi zambiri zimawonedwa, chifukwa aliyense ntchito ntchito wobiriwira solder kukana inki kupanga matabwa dera, ndi opanga solder kukana inki zambiri kutulutsa mafuta obiriwira, ndipo mtengo adzakhala wotsika kuposa inki mitundu ina.pafupifupi zonse zilipo.Zoonadi, makasitomala ena adzafunikanso mitundu ina, monga yakuda, yofiira, yachikasu, ndi zina zotero, zomwe ziyenera kusindikizidwa ndi solder kukana inki zamitundu ina.

Inki pa bolodi la dera la PCB, kunena zambiri, ziribe kanthu mtundu wa inki wotsutsa ndi wotani, zotsatira zake sizosiyana kwambiri.Chifukwa chachikulu ndi kusiyana kwa masomphenya.Pokhapokha kuti zoyera zimagwiritsidwa ntchito pazitsulo za aluminiyamu ndi kuwala kwambuyo, padzakhala kusiyana kwina kwa kuwala kowala, ndipo mitundu ina imagwiritsidwa ntchito poteteza ndi kuteteza.
Solder kukana inki zamitundu yosiyanasiyana amasindikizidwa pa bolodi dera.Ngakhale kuti palibe kusiyana kwakukulu mu ntchito, pali kusiyana pang'ono.Choyamba, zikuwoneka mosiyana.Mosasamala, ndikumva kuti zakuda ndi zabuluu ndizokwera kwambiri, ndipo zofunikira zidzakhala zapamwamba.Komabe, matabwa ozungulira ntchito wobiriwira solder kukana inki ndi wamba kwambiri, kotero amaona wamba kwambiri.Ma board ambiri ambali imodzi amagwiritsa ntchito inki yobiriwira ya solder.Poyerekeza ndi wakuda, sikophweka kuona mzere wa mzere, ndipo ntchito yophimba idzakhala yabwino, yomwe ingalepheretse anzawo kuti asatengere bolodi pamlingo winawake.Choyera chimawunikira bwino ndipo chimagwiritsidwa ntchito powunikira kapena kuyatsanso.
Inki yokaniza ya solder yomwe imagwiritsidwa ntchito m'mabokosi ambiri ndi yobiriwira, ndipo inki yokaniza yomwe imagwiritsidwa ntchito pama board osinthika amafoni am'manja imakhala yakuda ndi yoyera.The chingwe bolodi ndi kamera module board makamaka ntchito yellow solder kukana inki, ndi kuwala Mzere bolodi amagwiritsa woyera kapena matte woyera solder kukana inki.

Nthawi zambiri, mtundu wa solder kukana inki ntchito pa PCB makamaka zimadalira zofuna za makasitomala a fakitale gulu gulu.Sindikizani filimuyo.Pa matabwa flexible dera, white solder kukana inki ndi zochepa kugonjetsedwa ndi kupinda kuposa mitundu ina.
Palinso ma inki ena a solder pamagulu ozungulira okhala ndi mitundu yapadera.Ma inki ambiri a solder amakana mtundu wapaderawu amapangidwa ndi opanga inki, ndipo ena amasakanizidwa ndi inki ziwiri zotsutsana ndi solder mu gawo linalake.Sakanizani (m'mafakitale ena akuluakulu a board board, akatswiri amafuta mkati amatha kupaka utoto)
Ziribe kanthu mtundu wa mtundu wa PCB solder kukana inki, uyenera kukhala ndi kusindikiza kwabwino ndi kusamvana, kuti ukwaniritse zofunikira zosindikizira za fakitale ndi zofunikira zopanga.
