Pcb itunganya prototype ikibaho 94v-0 Ikibaho cyumuzunguruko wa Halogen

Igipimo cyumuriro cyicapiro cyumuzunguruko cyerekanwe kurwego rwumuriro wubuyobozi. Ikibaho cyumuzunguruko cyacapwe mubusanzwe bikozwe mubirahuri bya fibre hamwe numuriro wa FR-4. Ibi bikoresho bifite umuriro mwinshi kandi birashobora gukumira umuriro kurwego runaka. Birumvikana ko, ukurikije ibintu nkibisabwa ibisabwa nibisabwa kugirango umutekano ubeho, igipimo cyumuriro cyibibaho byumuzunguruko byanditse birashobora kandi gukoresha ibindi bikoresho bitandukanye.

Igipimo cyihariye cya UL94v0 nuko ikibaho cyumuzunguruko cyageze ku gipimo cyo kuzimya umuriro. ul94 ibikoresho nibikoresho byo gutwika ikizamini cyibikoresho bya pulasitike, hamwe nizina risanzwe, urugero rwo gusaba, gushyira mu byiciro, ibipimo bifitanye isano, nibindi. UL94 Ikizamini cyo gutwika ibikoresho bya plastike - Ibyiciro:

1) Urwego rwa HB: Ikizamini cyo Gutwika Horizontal

2) Urwego V0-V2: Ikizamini cyo gutwika Vertical Ikizamini cyo gutwika

Urwego rwa flame retardant ya plastike yiyongera kuva HB, V-2, V-1 kugeza kuri V-0 intambwe ku yindi:

UL 94 (Ikizamini cyo gutwika ibikoresho bya plastiki)

HB: Urwego rwohejuru rwa flame retardant murwego rwa UL94. Kuburugero rwa mm 3 kugeza kuri 13, gutwika ku gipimo kiri munsi ya mm 40 kumunota naho kuburugero rwa mm 3 z'ubugari, gutwika ku gipimo kiri munsi ya mm 70 kumunota cyangwa kuzimya mbere yikimenyetso cya mm 100.

V-2: Umuriro wazimye mu masegonda 30 nyuma y'ibizamini bibiri byo gutwika 10-isegonda. Irashobora gutwika ipamba 30cm.

V-1: Umuriro wazimye mu masegonda 30 nyuma y'ibizamini bibiri byo gutwika 10-isegonda. Ntugatwike ipamba 30cm.

V-0: Umuriro uzimya mumasegonda 10 nyuma yikizamini cya kabiri cyamasegonda 10 kuri sample

Ukurikije urwego rwamanota kuva hasi kugeza murwego rwo hejuru kuburyo bukurikira: 94HB / 94VO / 22F / CIM-1 / CIM-3 / FR-4, ibiranga flame retardant biranga kugabana amanota birashobora kugabanywa muri 94V-0 / V- 1 / V-2, 94-HB ubwoko bune; 94HB: ikibaho gisanzwe, nta muriro (ibikoresho byo mu rwego rwo hasi, gupfa gukubita, ntibishobora gukora ikibaho cyamashanyarazi) 94V0: ikibaho cya flame retardant (gupfa gukubita) 22F: uruhande rumwe igice cyikirahure cya fibre fibre (gupfa gukubita) CIM-1: umwe- Ikibaho cyibirahure byuruhande (bigomba kuba gucukura mudasobwa, ntibishobora gupfa gukubita) CIM-3: Ikibaho cyibice bibiri byikirahure cyibibaho FR-4: ikibaho cyibirahure

Byibanze cyane ku mbaho ​​zose za Shenzhen Lianchuang Electronics Co., Ltd, igipimo cy’umuriro cyujuje 94v-0!

Ikibaho kitarimo Halogen kubibaho byacapishijwe byerekanwa ibikoresho bidafite halogene bikoreshwa mugukora imbaho ​​zicapye. Ibikoresho bitarimo Halogene bivuga ibikoresho bitarimo ibintu bya halogene nka chlorine na bromine. Ibi bikoresho byangiza ibidukikije kandi bifite umutekano kuruta ibikoresho bisanzwe birimo halogene, kandi birashobora kugabanya kwangiza ibidukikije numubiri wabantu. Mu bihugu bimwe na bimwe, gukoresha ibikoresho bitarimo halogene mu gukora imbaho ​​z’umuzunguruko byaciwe byemewe n'amategeko cyangwa amahame y’inganda hagamijwe guteza imbere iterambere rirambye no kurengera ibidukikije.
