FAQ
HASL inorevei mukugadzira PCB?
HASL zvinoreva Kupisa Air Solder Kuenzana. Inopfekedza nzvimbo dzePCB ne solder. Izvi zvinodzivirira mhangura uye zvinobatsira ne soldering panguva yegungano.
Inotungamira HASL inogona kushandiswa mumagetsi emazuva ano here?
Hongu, asi mune mamwe minda chete. Inotungamira HASL inoshandiswa mumauto, aerospace, uye maindasitiri mapurojekiti. Nzvimbo idzi hadziteveri mitemo yakasimba senge RoHS. Asi kune zvemagetsi zvevatengi kana maturusi ekurapa, inotungamira-yemahara kupera inowanzodiwa.
Sei HASL isina lead ichidhura kupfuura LEad HASL?
LEad-isina HASL inoshandisa alloys anodhura serata-silver-copper. Inoda kupisa kwakawanda kwekutengesa nekuda kwekunyungudika kwayo kwepamusoro. Mafekitari angangodawo maturusi matsva ekutungamirira-isina maitiro, kukwidza mitengo.
Ini ndinotora sei pakati peHASL isina lead uye inotungamira?
Funga nezvezvido zvepurojekiti yako. Kune eco-hushamwari mitemo kana yakakwirira-kupisa kusimba, tora lead-isina HASL. Kune mapurojekiti akachipa kana mitemo isina kusimba, inotungamira HASL inogona kushanda zvirinani.
Inotungamira-isina HASL inoita kuti maPCB agare kwenguva refu?
Hungu, zvinodaro. LEad-isina HASL inodzivirira kupisa uye ngura zviri nani. Aya maficha anobatsira maPCB kugara kwenguva refu, kunyanya munzvimbo dzakaoma semafekitori kana mota.
