Isicelo

Isilinganiso somlilo sebhodi lesifunda eliphrintiwe libhekisela esilinganisweni somlilo sebhodi.Amabhodi esekethe aphrintiwe ngokuvamile enziwa nge-glass fiber material enesilinganiso somlilo esingu-FR-4.Lesi sici sinesilinganiso somlilo esiphezulu futhi singavimbela imililo ngezinga elithile.Yiqiniso, ngokuya ngezici ezifana nezidingo zohlelo lokusebenza kanye nezidingo zokuphepha, isilinganiso somlilo samabhodi esekethe aphrintiwe singasebenzisa nezinye izinto ezihlukile kanye namazinga.

Izinga elithile le-UL94v0 liwukuthi ibhodi lesifunda selifinyelele izinga lokuvimbela umlilo.Isivivinyo sokushiswa kwemishini ye-UL94 nezinto zikagesi zepulasitiki, ezinegama elijwayelekile, ububanzi bokusebenza, ukuhlukaniswa kwezigaba, izindinganiso ezihlobene, njll. Ukuhlolwa kokusha kwe-Plastiki ye-UL94 - Ukwahlukaniswa:

1) Izinga le-HB: Ukuhlolwa Okushisayo Okuvundlile

2) Izinga le-V0-V2: Isivivinyo Sokushiswa Okuqondile Ukuhlolwa kokushiswa okuqondile

Ibanga lamapulasitiki abushelelezi ilangabi liyakhuphuka lisuka ku-HB, V-2, V-1 liye ku-V-0 isinyathelo ngesinyathelo:

I-UL 94 (Ukuhlolwa kokuvutha kwezinto zepulasitiki)

I-HB: Ibanga eliphansi kakhulu le-flame retardant ku-UL94 ejwayelekile.Kumasampula awugqinsi obungu-3 kuya ku-13 mm, shisa ngenani elingaphansi kuka-40 mm ngomzuzu futhi kumasampula ubukhulu obungu-3 mm, shisa ngenani elingaphansi kuka-70 mm ngomzuzu noma ucime ngaphambi kophawu luka-100 mm.

I-V-2: Ilangabi licime phakathi kwamasekhondi angu-30 ngemva kokuhlolwa kokuvutha kwemizuzwana eyi-10 kwesampula.Ingathungela ukotini ongu-30cm.

I-V-1: Ilangabi licime phakathi kwamasekhondi angu-30 ngemva kokuhlolwa kokuvutha kwemizuzwana eyi-10 kwesampula.Ungabasi ukotini ongu-30cm.

I-V-0: Ilangabi liyacima phakathi nemizuzwana eyi-10 ngemuva kokuhlolwa kokuvutha kwemizuzwana eyi-10 kusampula

Ngokwezinga lebanga ukusuka phansi kuya ekuhlukaniseni okuphezulu kanje: 94HB/94VO/22F/CIM-1/CIM-3/FR-4, izici ezivimba ilangabi zokuhlukaniswa kwebanga zingahlukaniswa zibe yi-94V-0 / V- 1 /V-2, 94-HB izinhlobo ezine;I-94HB: ibhodi elivamile, akukho mlilo (izinto ezisezingeni eliphansi kakhulu, i-die punching, ayikwazi ukwenza ibhodi lamandla) 94V0: ibhodi elibushelelezi ilangabi (i-die punching) 22F: ibhodi elilodwa lengilazi yengilazi enguhhafu (i-die punching) CIM-1: i-single- ibhodi lefibre yengilazi eseceleni (kumele kube yi-computer drilling, ayikwazi ukufa ngokushaya) I-CIM-3: Ibhodi lefayibha yengilazi enezinhlangothi ezimbili FR-4: ibhodi yengilazi enezinhlangothi ezimbili

Okugcizelelwa ngokukhethekile wonke amabhodi e-Shenzhen Lianchuang Electronics Co.,Ltd, isilinganiso somlilo sihlangabezana ne-94v-0!

Amabhodi angenawo ama-halogen amabhodi esekethe aphrintiwe abhekisela ezintweni ezingenazo i-halogen ezisetshenziswa ekwenzeni amabhodi esekethe aphrintiwe.Izinto ezingenayo i-halogen zibhekisela ezintweni ezingenayo izakhi ze-halogen njenge-chlorine ne-bromine.Lezi zinto zinobungani bemvelo futhi ziphephe kakhulu kunezinto zendabuko eziqukethe i-halogen, futhi zinganciphisa ukulimala kwemvelo nomzimba womuntu.Kwamanye amazwe nezifunda, ukusetshenziswa kwezinto ezingenazo i-halogen ukwenza amabhodi esekethe aphrintiwe sekuyisidingo esingokomthetho noma indinganiso yezimboni ukukhuthaza intuthuko esimeme nokuvikelwa kwemvelo.

Imibuzo Evame Ukubuzwa

1.Siyini isilinganiso sokuvutha kwe-PCB?

Iningi lama-PCB ahlukaniswa njenge-FR-4, okubonisa ukuthi ahlangabezana nemibandela ethile yokusebenza, kanye nezimfuneko ze-V0 ze-UL (Underwriters Laboratories) 94 izinga lokuhlola ukuvutha.

2.Yini ubukhulu obuncane be-UL 94 v0?

I-UL 94 isetshenziselwa ukukala izinga lokushiswa nezici ngokusekelwe kumasampuli ajwayelekile.Usayizi wesampula ngu-12.7mm ngo-127mm, nogqinsi luhluka ukusuka ku-0.8mm kuya ku-3.2mm.

3.Iyini i-PCB yamahhala ye-halogen?

I-PCB yamahhala ye-halogen iyibhodi lesifunda eliphrintiwe elinezici ze-halogen ezilinganiselwe.Izakhi eziyinhloko ze-halogen ezibulala ukuphila i-chlorine, i-fluorine, i-bromine, i-astatine, ne-iodine.I-PCB yamahhala ye-halogen ine-bromine noma i-chlorine engaphansi kuka-900 ppm.Futhi, ibhodi lingaphansi kwe-1500 ppm yezinto ze-halogen.

4.Kungani ama-halogen engalungile emvelweni?

Ngaphezu kwalokho, ama-halogen ehlisa izinga lomoya ngokukhuthaza ukwakheka kwe-ozone engaphezulu.Ezingeni eliphansi, i-ozone iwukungcola (negesi ebamba ukushisa) futhi ukuchayeka isikhathi eside kungaholela ezifweni zokuphefumula, okuhlanganisa isifuba somoya, futhi kulimaza izitshalo.

5.Kungani ama-halogen engekho mahhala emvelweni?

Izinsimbi ze-alkali nama-halogen azenzeki mahhala emvelweni ngoba zisebenza kakhulu.Zenzeka esimweni esihlangene.
