Application
Iyo yedunhu bhodhi HASL maitiro anowanzo inoreva pad HASL maitiro, ari kupfekedza tini panzvimbo yepadhi pamusoro pebhodhi redunhu.Inogona kutamba basa rekudzivirira-corrosion uye anti-oxidation, uye inogonawo kuwedzera nzvimbo yekubatana pakati pedhi uye soldered device, nekuvandudza kuvimbika kwekutengesa.Iyo chaiyo inoyerera inoyerera inosanganisira akawanda matanho akadai sekuchenesa, makemikari deposition yetin, kunyura, uye rinsing.Zvadaro, mune imwe nzira yakadai semhepo inopisa solder, ichaita kuti iite chisungo pakati peti uye splice device.Kupfapfaidza tini pamabhodhi edunhu inzira inowanzoshandiswa uye inoshandiswa zvakanyanya muindasitiri yekugadzira magetsi.
Lead HASL uye lead-isina HASL maviri epamusoro ekurapa matekinoroji ayo anonyanya kushandiswa kuchengetedza zvikamu zvesimbi zvemabhodhi edunhu kubva mukuora uye oxidation.Pakati pavo, kuumbwa kwemutobvu HASL inoumbwa ne63% tin uye 37% lead, nepo HASL isina lead inoumbwa netin, mhangura uye zvimwe zvinhu (senge sirivheri, nickel, antimony, nezvimwewo).Kuenzaniswa neHASL ine lead, musiyano uripo pakati peHASL isina lead-isina ndewekuti ishamwari yezvakatipoteredza, nekuti mutobvu chinhu chinokuvadza chinoisa mungozi nharaunda uye hutano hwevanhu.Pamusoro pezvo, nekuda kwezvinhu zvakasiyana zviri muHASL isina lead-isina, solder yayo nemagetsi zvimiro zvakasiyana zvishoma, uye inoda kusarudzwa zvinoenderana nezvinodiwa zvekushandisa.Kazhinji, mutengo weHASL isina lead wakakwira zvishoma pane weHASL yemutobvu, asi kuchengetedza kwayo kwezvakatipoteredza uye kugona kwayo kuri nani, uye inofarirwa nevazhinji vashandisi.
Kuti uteedzere kuraira kweRoHS, zvigadzirwa zvemabhodhi edunhu zvinofanirwa kusangana neanotevera mamiriro:
1. Zvinyorwa zvemutobvu (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), polybrominated biphenyls (PBB) uye polybrominated diphenyl ethers (PBDE) inofanira kuva shoma pane yakatarwa muganhu kukosha.
2. Zviri mukati mesimbi dzinokosha sebismuth, sirivha, goridhe, palladium, uye platinamu zvinofanira kunge zviri mukati memiganhu inonzwisisika.
3. Hurukuro hwehalogen hunofanirwa kunge huri pasi pemutengo wakatarwa, kusanganisira chlorine (Cl), bromine (Br) uye iodine (I).
4. Bhodhi redunhu uye zvikamu zvaro zvinofanirwa kuratidza zvirimo uye kushandiswa kwezvinhu zvine chepfu uye zvinokuvadza.Izvo zviri pamusoro ndeimwe yemamiriro makuru ekuti mabhodhi edunhu atevedzere kuraira kweRoHS, asi izvo zvinodikanwa zvinofanirwa kutariswa zvinoenderana nemirairo yenzvimbo nezviyero.
FAQs
HASL kana HAL (yemhepo inopisa (solder) leveling) imhando yekupedzisa inoshandiswa pamabhodhi edunhu akadhindwa (PCBs).Iyo PCB inowanzonyudzwa mubhavhu rekunyungudusa solder kuitira kuti ese ari pachena mhangura akafukidzwa nesolder.Yakawandisa solder inobviswa nekupfuura PCB pakati pemhepo inopisa mapanga.
HASL (Standard): Kazhinji Tin-Lead - HASL (Lead Free): Kazhinji Tin-Copper, Tin-Copper-Nickel, kana Tin-Copper-Nickel Germanium.Yakajairika ukobvu: 1UM-5UM
Iyo haishandise Tin-Lead solder.Pane kudaro, Tin-Copper, Tin-Nickel kana Tin-Copper-Nickel Germanium inogona kushandiswa.Izvi zvinoita kuti Lead-Yemahara HASL ive yehupfumi uye RoHS inoenderana sarudzo.
Hot Air Surface Leveling(HASL) inoshandisa lead sechikamu cheiyo solder alloy, iyo inonzi inokuvadza kuvanhu.Nekudaro, Lead-isina Kupisa Mhepo Yepamusoro Yepamusoro (LF-HASL) haishandise lead seyakagadzirwa solder alloy yayo, zvichiita kuti ive yakachengeteka kuvanhu uye nharaunda.
HASL ine hupfumi uye inowanikwa zvakanyanya
Iyo ine yakanakisa solderability uye yakanaka sherufu hupenyu.
