Kugwiritsa ntchito
Chiwerengero cha moto cha bolodi losindikizidwa chimatanthawuza chiwerengero cha moto cha bolodi.Ma board ozungulira osindikizidwa nthawi zambiri amapangidwa ndi zinthu zamagalasi zokhala ndi moto wa FR-4.Zinthuzi zimakhala ndi mtengo wapamwamba wamoto ndipo zimatha kuteteza moto pamlingo wina wake.Zachidziwikire, malingana ndi zinthu monga zofunikira pakugwiritsa ntchito komanso zofunikira zachitetezo, kuchuluka kwamoto pama board ozungulira osindikizidwa kumathanso kutenga zida ndi miyezo ina.
Muyezo weniweni wa UL94v0 ndikuti bwalo loyang'anira dera lafika pamlingo wa retardant moto.Zida za ul94 ndi zida zoyatsira zida za pulasitiki zokhala ndi dzina lokhazikika, kuchuluka kwa ntchito, gulu lamagulu, milingo yofananira, ndi zina. UL94 Mayeso oyatsa pulasitiki - Gulu:
1) Mulingo wa HB: Mayeso Oyatsa Chopingasa
2) V0-V2 mlingo: Vertical Burning Test Vertical burning test
Kuchuluka kwa mapulasitiki oletsa moto kumawonjezeka kuchokera ku HB, V-2, V-1 mpaka V-0 sitepe ndi sitepe:
UL 94 (Kuyesa kwamphamvu kwazinthu zapulasitiki)
HB: Gawo lotsika kwambiri lamoto wamoto mu UL94 muyezo.Kwa zitsanzo za 3 mpaka 13 mm wandiweyani, itentheni pa mlingo wochepera 40 mm pa mphindi imodzi ndi zitsanzo za 3 mm zokhuthala, zitentheni pa mlingo wosakwana 70 mm pa mphindi kapena kuzimitsa pamaso pa 100 mm chizindikiro.
V-2: Lawi lamoto linazimitsidwa mkati mwa masekondi a 30 pambuyo pa mayesero awiri a 10-sekondi imodzi ya chitsanzo.Imatha kuyatsa thonje 30cm.
V-1: Lawi lamoto linazimitsidwa mkati mwa masekondi a 30 pambuyo pa mayesero awiri a 10-sekondi imodzi ya chitsanzo.Osayatsa thonje 30cm.
V-0: Lawi lamoto lizimitsidwa mkati mwa masekondi 10 pambuyo pa mayeso awiri a 10-sekondi imodzi pa chitsanzo.
Malinga ndi kalasi mlingo kuchokera pansi mpaka magawano mkulu motere: 94HB/94VO/22F/ CIM-1 / CIM-3 /FR-4, lawi retardant makhalidwe a magawano kalasi akhoza kugawidwa mu 94V-0 / V- 1 /V-2, 94-HB mitundu inayi;94HB: bolodi wamba, palibe moto (zotsika kwambiri kalasi, kufa kukhomerera, sangathe kuchita bolodi mphamvu) 94V0: lawi retardant bolodi (kufa kukhomerera) 22F: single mbali theka galasi fiber bolodi (kufa kukhomerera) CIM-1: single- mbali ya galasi fiber board (ayenera kukhala kubowola pakompyuta, sangafe kukhomerera) CIM-3: Pawiri mbali ziwiri theka galasi fiber bolodi FR-4: pawiri mbali galasi CHIKWANGWANI bolodi
Kutsimikiza kwapadera ndi matabwa onse a Shenzhen Lianchuang Electronics Co., Ltd, amakumana ndi 94v-0!
Ma board opanda halogen a matabwa osindikizira amatanthawuza zinthu zopanda halogen zomwe zimagwiritsidwa ntchito popanga matabwa osindikizira.Zida zopanda halogen zimatanthawuza zinthu zomwe zilibe zinthu za halogen monga chlorine ndi bromine.Nkhaniyi ndi yochezeka komanso yotetezeka kuposa zida zachikhalidwe zomwe zimakhala ndi halogen, ndipo zimatha kuchepetsa kuwononga chilengedwe komanso thupi la munthu.M'mayiko ndi zigawo zina, kugwiritsa ntchito zipangizo zopanda halogen kupanga mapepala osindikizira osindikizira kwakhala chofunikira mwalamulo kapena muyeso wamakampani kuti apititse patsogolo chitukuko chokhazikika ndi kuteteza chilengedwe.
FAQs
Ma PCB ambiri amasankhidwa kukhala FR-4, kusonyeza kuti amakwaniritsa zofunikira zina, komanso zofunikira za V0 za UL (Underwriters Laboratories) 94 kuyesa kuyesa moto.
UL 94 imagwiritsidwa ntchito kuyeza kuchuluka kwa kuyaka ndi mawonekedwe kutengera zitsanzo wamba.Kukula kwachitsanzo ndi 12.7mm ndi 127mm, ndi makulidwe osiyanasiyana kuchokera ku 0.8mm mpaka 3.2mm.
PCB yaulere ya halogen ndi bolodi losindikizidwa lokhala ndi zinthu zochepa za halogen.Zinthu zazikulu za halogen zomwe zimapha moyo ndi chlorine, fluorine, bromine, astatine, ndi ayodini.PCB yaulere ya halogen ili ndi zosakwana 900 ppm za bromine kapena klorini.Komanso, bolodi ili ndi zosakwana 1500 ppm za zida za halogen.
Kuphatikiza apo, ma halogen amawononga mpweya wabwino polimbikitsa mapangidwe a ozoni.Pansi, ozoni ndi woipitsa (& mpweya wowonjezera kutentha) ndipo kuwonekera kwanthawi yayitali kungayambitse matenda opumira, kuphatikiza mphumu, ndipo kumawononga mbewu.
Zitsulo za alkali ndi ma halojeni sizichitika mwaulere m'chilengedwe chifukwa zimakhala zotakataka.Iwo amachitika mu chikhalidwe chophatikizana.
