Gucukumbura ibipimo ntarengwa bya voltage yo gukora byihuse PCB

Intangiriro:

Mwisi yihuta cyane yisi ya elegitoroniki, hakenewe serivisi zinganda zumuzunguruko zikora neza, byihuse cyane kuruta mbere hose. Ibigo nka Capel, bifite uburambe bwimyaka 15 mubikorwa byubuyobozi bwumuzunguruko, byujuje iki cyifuzo gikura. Mugihe wubaka PCB, ikintu cyingenzi ugomba gusuzuma ni igipimo ntarengwa cya voltage. Igipimo ntarengwa cya voltage kigena urwego rwa voltage PCB ishobora gukemurwa neza nta byangiritse cyangwa ibibazo byimikorere.Muri iyi blog, tuzareba neza ibipimo ntarengwa bya voltage kubikorwa byihuse bya PCB nuburyo Capel itanga ibisubizo byizewe kugirango ihuze ibyifuzo byabakiriya neza kandi bihendutse.

Menya voltage ntarengwa yagenwe:

Igipimo ntarengwa cya voltage nigisobanuro gikomeye mugihe cyo gushushanya no gukora imbaho ​​zumuzunguruko. Yerekeza kuri voltage ndende ikibaho cyumuzunguruko gishobora gukemura neza nta cyangiritse cyangwa cyatsinzwe. Ibi bisobanuro bifite uruhare runini muguhitamo imikorere rusange nubwizerwe bwibikoresho bya elegitoroniki.

Ubwa mbere, ni ngombwa kumva ko igipimo ntarengwa cya voltage ya PCB atari agaciro gahamye ahubwo biterwa nibintu byinshi. Ibi bintu birimo ibikoresho byakoreshejwe, ubunini bwurwego rwumuringa, intera iri hagati yimiterere, hamwe nigishushanyo mbonera cyumuzunguruko. Buri kimwe muri ibyo bihinduka kigira uruhare runini mukumenya urwego rwumutekano wa PCB rushobora gukora.

Guhindura Byihuse PCB Ibihimbano na Voltage Ibipimo:

Guhindura byihuse PCB, nkuko izina ribigaragaza, ishimangira umusaruro wihuse utabangamiye ubuziranenge. Iyo bigeze ku ntera ntarengwa ya voltage, umuvuduko nukuri bigomba kuringanizwa kugirango uruziga rushobore guhangana n’ingutu ziteganijwe n’amashanyarazi. Iyo bigeze ku gukora byihuse PCB, igihe ni cyo kintu. Kubwibyo, inzira yo gukora irashobora gukomeza vuba, ariko ni ngombwa kutabangamira ubuziranenge n’umutekano. Mubikorwa byihuta byinganda, biba ngombwa cyane gusuzuma igipimo ntarengwa cya voltage, kuko intera yamakosa yo kwemeza PCB kwizerwa ishobora kuba nto.

Guhitamo Ibikoresho:

Ikintu cyingenzi ugomba gusuzuma mugihe ukora PCBs hamwe na voltage nini cyane ni uguhitamo ibikoresho. Ibikoresho bihebuje bifite ibikoresho byiza byamashanyarazi, nka FR-4, mubisanzwe bikunzwe. FR-4 ni flame-retardant fiberglass yongerewe imbaraga epoxy ibikoresho bikoreshwa cyane mubikorwa bya PCB kubera ibikoresho byiza bya mashini n'amashanyarazi. Umuvuduko wacyo wa voltage ni 40 kugeza 150 kV / mm (kV / mm), bigatuma bikenerwa mubikorwa bitandukanye.

Ubuhanga bwa Capel mubikorwa byihuse bya PCB:

Nuburambe bunini bwinganda, Capel yumva akamaro ko guhaza ibyo umukiriya akeneye neza mugukomeza ubudakemwa bwibicuruzwa. Itsinda ryabo ryinzobere zifite ubuhanga bukoresha ibikoresho nubuhanga bugezweho bwo gukora nubuhanga kugirango batange amakuru yizewe kandi yizewe yumuzunguruko wa prototyping numusaruro mwinshi.

Igisubizo cyizewe cya Capel:

Capel kabuhariwe mugutanga ibisubizo byizewe kugirango ihuze abakiriya ba voltage ikenewe cyane. Bashyira imbere gusobanukirwa ibyifuzo bya buri mushinga, harimo ningufu za voltage zisabwa nimpamvu ziterwa numuriro. Muguhuza ubuhanga nubuhanga bugezweho, Capel yemeza ko imbaho ​​zumuzunguruko zikora zujuje ibipimo bya voltage bikenewe.

Inganda zikora neza, zujuje ubuziranenge, zubukungu:

Capel yishimira guha abakiriya ibisubizo byiza, byujuje ubuziranenge kandi bihendutse. Mugukoresha uburyo bwabo bworoshye nibikoresho bigezweho, birashobora kubyara byihuse imbaho ​​zujuje ibyangombwa bya voltage bikenewe. Uku gukora neza gutezimbere bivamo kuzigama ibiciro no guhinduka byihuse utabangamiye ubuziranenge bwibicuruzwa byanyuma.

Uzuza ibyifuzo byabakiriya:

Capel izi ko buri mushinga ufite ibyo ukeneye byihariye. Byaba aribisabwa kurwego rwihariye rwa voltage, imbogamizi zingana cyangwa ibindi bisobanuro, bafite ubuhanga bwo gutanga ibisubizo byabigenewe neza. Itsinda ryabo ryinzobere ryita cyane kubisobanuro birambuye, byemeza ko buri kibaho cyumuzunguruko cyakozwe kugirango abakiriya babone neza.

Ingaruka ya voltage ntarengwa yagenwe kumikorere yumuzunguruko:

Igipimo ntarengwa cya voltage cyumuzunguruko ni ikintu cyingenzi muguhitamo imikorere no kuramba mubikorwa bitandukanye. Gutegura no gukora PCBs hamwe nu gipimo cya voltage cyujuje cyangwa kirenze ingufu ziteganijwe n’amashanyarazi ni ngombwa mu kwirinda kunanirwa, guhungabanya umutekano, n’imikorere yangiritse.

Ubwitange bwa Capel kumutekano wabakiriya no kunyurwa:

Capel ishyira umutekano wabakiriya no kunyurwa mbere kumushinga wose bakora. Mugukurikiza byimazeyo amahame yinganda no gukoresha ubumenyi bwabo bwinshi, baremeza ko imbaho ​​bakora zishobora kwihanganira imashanyarazi iteganijwe. Uku kwiyemeza ubuziranenge bituma abakiriya bakira PCBs zizewe, zifite umutekano zujuje ibyangombwa byihariye bya voltage.

Mu gusoza:

igipimo ntarengwa cya voltage kubikorwa byihuse PCB ninganda zingenzi mugutekereza kubikorwa byizewe kandi byizewe byibikoresho bya elegitoroniki.Ibintu nko gutoranya ibikoresho, uburebure bwumuringa, intera yumwanya, hamwe nigishushanyo mbonera byose bifasha kumenya igipimo ntarengwa cya voltage ya PCB. Mugihe uhisemo ibicuruzwa byihuta, umuvuduko nubwiza bigomba gushyirwa imbere bitabangamiye umutekano wingenzi. Mu isi yihuta cyane mu gukora PCB, Capel igaragara hamwe nuburambe bwimyaka 15 nubushake bwo gutanga ibisubizo byiza, byujuje ubuziranenge nubukungu. Kumenya igipimo ntarengwa cya voltage yikibaho cyumuzunguruko ni ngombwa kugirango wizere kandi ukore neza ibikoresho bya elegitoroniki. Ubuhanga bwa Capel mukuzuza ibyifuzo byabakiriya, hamwe nubwitange bwabo mumutekano no kunyurwa, bituma bahitamo neza kubikenerwa byihuse PCB ikenera nibisabwa na voltage neza.
