Makhalidwe a PCB
1. Solderresistant inki (Solderresistant/SolderMask): Sikuti malo onse amkuwa amayenera kudya malata, kotero malo osadyedwa amasindikizidwa ndi zinthu zosanjikiza (nthawi zambiri epoxy resin) zomwe zimalekanitsa mkuwa kuti usadye malata. pewani kusagulitsa. Pali kagawo kakang'ono pakati pa mizere yamalata. Malingana ndi njira zosiyanasiyana, zimagawidwa kukhala mafuta obiriwira, mafuta ofiira ndi mafuta a buluu.
2. Dielectric wosanjikiza (Dielectric): Amagwiritsidwa ntchito kusunga kusungunula pakati pa mizere ndi zigawo, zomwe zimadziwika kuti gawo lapansi.
3. Chithandizo chapamwamba (SurtaceFinish): Popeza kuti pamwamba pa mkuwa ndi oxidized mosavuta m'madera ambiri, sungapangidwe (osasunthika bwino), kotero kuti mkuwa wotsekedwa udzatetezedwa. Njira zodzitetezera zimaphatikizapo HASL, ENIG, Immersion Silver, Immersion TIn, ndi organic solder preservative (OSP). Njira iliyonse ili ndi ubwino wake ndi zovuta zake, zomwe zimatchulidwa pamodzi ngati chithandizo chapamwamba.

Ma board athu a PCBA adapangidwa kuti akwaniritse zofuna zomwe zikukula izi popereka mayankho ochita bwino kwambiri omwe amaphatikiza liwiro, magwiridwe antchito, komanso kusungirako / kusinthanitsa kwanzeru. Kaya ndinu opereka chithandizo pakompyuta pamtambo, wosanthula deta wamkulu kapena nsanja yapa media, ma board athu a PCBA ndi abwino kwa inu.
Gulu la PCBA limapangidwa ndi zinthu zapamwamba kwambiri za Fr-4 kuti zitsimikizire kulimba komanso kudalirika. Lili ndi zigawo 14, zomwe zimapereka malo okwanira a zigawo zikuluzikulu ndikuthandizira kugwirizanitsa dera lapamwamba. Ndi makulidwe a 1.6mm, yakwaniritsa bwino pakati pa kuphatikizika ndi magwiridwe antchito.
Timamvetsetsa kufunikira kwa kulondola kowerengeka, ndichifukwa chake timapanga matabwa a PCBA okhala ndi mawonekedwe ocheperako / danga lakunja la 4/4mil. Izi zimatsimikizira kutumiza kwazizindikiro kosalala ndikuchepetsa chiopsezo chosokoneza. pa malire otsika kwambiri. Kukula kwa 0.25mm pobowola kumatsimikizira kugwirizana kwakukulu kwa ntchito, ndikupangitsa kuti ikhale yoyenera pazochitika zosiyanasiyana zamakompyuta.
Kuti tiwongolere magwiridwe antchito ndikuteteza bolodi, timagwiritsa ntchito mahema kudzera munjira yomwe imalepheretsa chinyezi chilichonse kapena zowononga kulowa mu PCB. Izi zimatsimikizira kudalirika kwakukulu komanso moyo wautali pakompyuta yanu.
Kupereka kulumikizana kwapamwamba komanso kukana kwa dzimbiri, ma board athu a PCBA amakhala ndi kumaliza kwa ENIG komwe kumakhala ndi golide wocheperako kuposa faifi tambala. Izi zimathandizira kulumikizana mwamphamvu ndikuwonjezera magwiridwe antchito onse a board.
Mapulogalamu athu apakompyuta ndi zotumphukira za PCBA ndiye njira yothetsera zosowa zanu zamakompyuta. Ndi mawonekedwe ake apamwamba komanso mtundu wamtengo wapatali, imatsimikizira magwiridwe antchito odalirika komanso kusinthana kwa chidziwitso mwachangu. Khalani patsogolo pakusintha kwa digito ndi ma board athu apamwamba kwambiri a PCBA.
