Kuphatikiza apo, makulidwe onse a bolodi amawonjezeka kwambiri ndi mkuwa wolemera pa zigawo zingapo, zomwe zingakhudze njira zopangira zinthu monga kuboola ndi kuyika mabowo odutsa.
Kodi ma PCB olemera a mkuwa angagwiritsidwe ntchito ndi ukadaulo wopangira pamwamba (SMT)?
Inde, ma PCB olemera a mkuwa amatha kupangidwira zigawo za SMT. Komabe, zinthu zofunika kuziganizira mwapadera pakugwiritsa ntchito solder phala, kuyika zigawo, ndi ma profiles obwezeretsanso chifukwa cha kuchuluka kwa kutentha kwa zigawo zolemera za mkuwa. Zigawo za SMT zopyapyala zingafunike makulidwe wamba a mkuwa m'malo omwe zimayikidwa.
Kodi nchiyani chomwe chimaonedwa ngati "mkuwa wolemera" popanga ma PCB?
Kawirikawiri, makulidwe aliwonse a mkuwa opitilira 3 oz (105 µm) amaonedwa ngati mkuwa wolemera. Komabe, tanthauzo lake lingasiyane kutengera momwe ntchito ikuyendera komanso mafakitale ake. Opanga ena angaganize kuti 3 oz ndiye poyambira kugwiritsa ntchito mkuwa wolemera, pomwe ena angaike malire pa 4 oz kapena kupitirira apo.
Kodi mtengo wa ma PCB olemera a mkuwa umafanana bwanji ndi ma PCB wamba?
Ma PCB olemera a mkuwa nthawi zambiri amakhala okwera mtengo kuposa ma PCB wamba chifukwa cha zinthu zingapo: Kukwera mtengo kwa zinthu zopangira (mkuwa wambiri) Nthawi yayitali yokonza, makamaka podula Zida zodula kwambiri panthawi yopanga Njira zovuta zopangira zinthu Zitha kukhala zochepa chifukwa cha kulekerera kwa kupanga zinthu molimbika Komabe, mtengo wokwerawu ukhoza kuchepetsedwa ndi magwiridwe antchito abwino, kudalirika, komanso kuthekera kochepetsa kuchuluka kwa zigawo m'mapangidwe ena.
Kodi mumasankha bwanji makulidwe a mkuwa wa PCB?
Malinga ndi kagwiritsidwe ntchito kosiyanasiyana ka PCB, makulidwe a mkuwa ofunikira ndi osiyana. Monga ma PCB azinthu zogwiritsidwa ntchito ndi ogula komanso zolumikizirana, makulidwe a mkuwa a 0.5oz, 1oz, ndi 2oz amafunikira; pazinthu zamagetsi zomwe zimakhala ndi mphamvu yamagetsi yapamwamba, monga zinthu zamagetsi, ma board amagetsi, ndi zinthu zina, ma PCB nthawi zambiri amafunikira mkuwa wokhuthala woposa 3oz. Mwachidule, sankhani makulidwe oyenera a mkuwa malinga ndi zofunikira za chinthucho.
Kodi mu PCB muli zigawo zingati za mkuwa?
Pali gawo limodzi la mkuwa mu PCB yokhala ndi mbali imodzi. Pali zigawo ziwiri za mkuwa mu PCB yokhala ndi mbali ziwiri. Pali zigawo zoposa ziwiri za mkuwa mu PCB yokhala ndi zigawo zambiri. Mwachitsanzo, pali zigawo zinayi za mkuwa mu PCB yokhala ndi zigawo zinayi.
Kodi pali kusiyana kulikonse pakati pa bolodi lozungulira la mkuwa wolemera ndi ma PCB a mkuwa wokhuthala?
Palibe kusiyana pakati pa mawu awiriwa, onse amatanthauza ma circuit board osindikizidwa okhala ndi makulidwe a 3oz kapena makulidwe a mkuwa wokhuthala. Ma PCB a mkuwa wokhuthala kapena ma board a mkuwa wolemera amagwiritsidwa ntchito kwambiri m'ma board amagetsi amphamvu kwambiri.
Kodi kulemera kwa mkuwa kwa Heavy Copper PCBs ndi kotani?
Kulemera kwa mkuwa kwa ma PCB olemera amkuwa kumaposa ma ounces awiri (70um). Koma tikhozanso kupanga makulidwe apamwamba a mkuwa monga 4 oz copper PCB, 10 oz copper PCB ndi 20 oz copper PCB.
Ndi zipangizo ziti zomwe zimagwiritsidwa ntchito mu Heavy Copper PCBs?
Mkuwa wa RTF uyenera kugwiritsidwa ntchito.
Zinthu zabwino zodzaza mu lamination
Ma substrates amphamvu kwambiri otenthetsera kutentha
Kodi pali zinthu zina zomwe muyenera kuganizira popanga zinthu pogwiritsa ntchito Heavy Copper PCBs?
Ikani malo akuluakulu a mkuwa m'malo a mkuwa
Sungani mkuwa wotsala bwino
Wonjezerani m'lifupi ndi malo ofufuzira
Konzani kapangidwe ka pad ka mkati mwa chipindacho
Kodi ubwino wogwiritsa ntchito Heavy Copper PCBs ndi wotani?
Pitirizani ndi mafunde ambiri komanso ma voltages ambiri
Kudalirika kwambiri
Kupirira kutentha, kuzizira, ndi dzimbiri
Mzere wautali wa moyo
Kodi bolodi lozungulira losindikizidwa la mkuwa wa 2oz PCB?
Mu Richfulljoy, ma circuit board osindikizidwa okhala ndi makulidwe a 0.33oz, 0.5oz, 1oz ndi 2oz ndi makulidwe a mkuwa wamba. Chifukwa chake timaganiza kuti 2oz PCB si circuit board yolemera ya mkuwa, ndipo timaona ma PCB okhala ndi makulidwe a mkuwa a 3oz kapena kupitirira apo ngati ma board olemera a mkuwa.
