Umurongo umwe na PCBs nyinshi - Bitandukaniye he?

Inzira imwe PCB Vs Igice kinini PCB - Ibyiza, Ibibi, Igishushanyo nuburyo bwo gukora.

Mberegushushanya ikibaho cyacapwe, ugomba guhitamo niba wakoresha umurongo umwe cyangwa ibice byinshi PCB. Ubwoko bwibishushanyo byombi bikoreshwa mubikoresho byinshi bya buri munsi. Ubwoko bwumushinga ukoresha ikibaho uzagena icyakubera cyiza. Ikibaho kinini kirasanzwe kubikoresho bigoye, mugihe ikibaho kimwe gishobora gukoreshwa kubikoresho byoroshye. Iyi ngingo izagufasha kumva itandukaniro no guhitamo ubwoko bukwiye kumushinga wawe.

Ukurikije amazina yizi PCBs, birashoboka ko ushobora gukeka itandukaniro. Ikibaho kimwe gifite igipande kimwe cyibikoresho fatizo (bizwi kandi nka substrate), mugihe imbaho ​​nyinshi zirimo ibice byinshi. Iyo ubisuzumye neza, uzabona itandukaniro ryinshi muburyo izo mbaho ​​zubatswe n'imikorere.

Niba ushishikajwe no gusoma byinshi kuri ubu bwoko bubiri bwa PCB, komeza usome!

Umurongo umwe na PCBs nyinshi - Bitandukaniye he (1)

PCB imwe imwe ni iki?

Ikibaho cyuruhande rumwe kizwi kandi nkikibaho kimwe. Bafite ibice kuruhande rumwe nuburyo bwo kuyobora. Izi mbaho ​​zifite urwego rumwe rwibikoresho (mubisanzwe umuringa). Ikibaho kimwe kigizwe na substrate, ibyuma bitwara ibyuma, ibyuma birinda ibicuruzwa, hamwe na ecran ya silike. Ikibaho kimwe kiboneka mubikoresho byinshi byoroshye bya elegitoroniki.

Ibyiza bya Layeri imwe PCB

1. Ntibihendutse

Muri rusange, PCB imwe igizwe na PCB ntabwo ihenze cyane kubera igishushanyo cyayo cyoroshye. Ibyo ni ukubera ko bishobora gutezwa imbere muburyo bukoresha igihe bidashingiye ku mubare munini waIbikoresho bya PCB. Byongeye, ntibisaba ubumenyi bwinshi.

2. Byakozwe vuba

Hamwe nigishushanyo cyoroshye kandi gishingiye kumikoro make, PCBs imwe irashobora gukorwa mugihe gito! Nibyo, ibyo nibyiza cyane, cyane cyane niba ukeneye PCB vuba bishoboka.

3. Biroroshye kubyara umusaruro

PCB izwi cyane murwego rumwe PCB irashobora gushushanywa nta ngorane zubuhanga. Ibyo ni ukubera ko itanga uburyo bworoshye bwo gushushanya kuburyo ababikora nababigize umwuga bashobora kubibyaza umusaruro nta kibazo.

4. Urashobora gutumiza muri byinshi

Kubera inzira zabo ziterambere zoroshye, urashobora gutumiza byinshi muburyo bwa PCB icyarimwe. Urashobora no kwitegereza kubona igabanuka ryibiciro kuri buri kibaho niba utumije byinshi.

Ibibi bya PCB imwe

1. Umuvuduko muto nubushobozi

Izi mbaho ​​zumuzunguruko zitanga amahitamo make yo guhuza. Ibyo bivuze ko imbaraga rusange n'umuvuduko bizagabanuka. Byongeye kandi, ubushobozi bwo gukora buragabanuka bitewe nigishushanyo cyacyo. Umuzunguruko ntushobora gukora kububasha bukomeye.

2. Ntabwo itanga Umwanya munini

Ibikoresho bigoye ntabwo bizungukira kumurongo umwe wumuzunguruko. Ibyo ni ukubera ko itanga umwanya muto cyane kubwinyongeraIbigize SMDn'amasano. Insinga ziza guhura nizindi zizatera akanama gukora nabi. Imyitozo myiza ikubiyemo kwemeza ko ikibaho cyumuzunguruko gitanga umwanya uhagije kuri buri kintu.

3. Kinini kandi kiremereye

Uzakenera gukora ikibaho kinini kugirango utange ubushobozi bwinyongera kubikorwa bitandukanye. Ariko, gukora ibi bizongera uburemere bwibicuruzwa.

Gushyira mu bikorwa Inzira imwe PCB

Kubera igiciro gito cyo gukora, imbaho ​​zuruhande rumwe zirazwi mubikoresho byinshi byo murugo kandiibikoresho bya elegitoroniki. Ibi bizwi cyane kubikoresho bishobora kubika amakuru make. Ingero zimwe zirimo:

Abakora ikawa

Itara LED

Kubara

Icapa

● Amaradiyo

Supplies Amashanyarazi

Ubwoko butandukanye bwa Sensor

Drive Imodoka zikomeye za Leta (SSD)

PCB igizwe niki?

Ibice byinshi bya PCB bigizwe nimbaho ​​nyinshi zibiri zegeranye hejuru yizindi. Bashobora kugira imbaho ​​nyinshi nkuko bikenewe, ariko ndende ndende yari ifite uburebure bwa 129. Mubisanzwe bafite ibice biri hagati ya 4 na 12. Nyamara, umubare udasanzwe urashobora gukurura ibibazo nko kurigata cyangwa kugoreka nyuma yo kugurisha.

Ibice byinshi byububiko byububiko bifite ibyuma byayobora kuruhande. Buri kibaho cyahujwe hakoreshejwe ibikoresho byabugenewe hamwe nibikoresho byabigenewe. Ikibaho cyinshi gifite masike yo kugurisha kumpera.

Ibyiza bya Layeri nyinshi PCB

1. Imishinga igoye

Ibikoresho bigoye bishingiye kubice byongeweho hamwe nizunguruka mubisanzwe bikenera PCB nyinshi. Urashobora kwagura ikibaho ukoresheje inyongera yinyongera. Ibi bituma bikwiranye nizindi nzitizi zigaragaza amasano yinyongera, bitabaye ibyo ntibishobora kuba ku kibaho gisanzwe.

2. Biraramba

Ibice byinyongera byongera umubyimba wubuyobozi, bigatuma biramba. Ibi noneho bizemeza kuramba kandi bizemerera kurokoka ibintu bitunguranye, harimo ibitonyanga.

3. Kwihuza

Ibice byinshi byakenera kurenza ingingo imwe ihuza. Muri iki kibazo, ibice byinshi PCB ikenera gusa aho bihurira. Muri rusange, iyi nyungu igira uruhare mubikoresho byoroheje byoroheje nibikoresho byoroheje.

4. Imbaraga nyinshi

Ongeraho ubucucike kuri PCB igizwe ninzego nyinshi bituma iba ingirakamaro kubikoresho bikoresha ingufu. Mubisanzwe, ibi bivuze ko ishobora gukora vuba kandi neza. Ubushobozi bwiyongereye butuma bikwiranye nibikoresho bikomeye.

Ingaruka za Multilayer Layeri PCB

1. Birahenze cyane

Urashobora kwitega kuriha byinshi hamwe ninama yumuzunguruko myinshi kuko bisaba ibikoresho byongeweho, ubuhanga, nigihe cyo kwiteza imbere. Kubwiyi mpamvu, ugomba kwemeza ko gukoresha ibice byinshi ari byiza kuruta igiciro.

2. Igihe kirekire

Ibibaho byinshi bizatwara igihe kinini kugirango biteze imbere. Ibi biterwa nibice byingenzi bisaba gufunga kuburyo buri cyiciro kizakora ikibaho. Buri kimwe muribi kigira uruhare mugihe cyo kurangiza muri rusange.

3. Gusana birashobora kuba bigoye

Niba PCB igizwe nibice byinshi ihura nibibazo, noneho birashobora kugorana kuyisana. Ibice bimwe byimbere ntibishobora kurebwa hanze, bikagorana kumenya ibitera ibice cyangwa ibyangiritse byangirika. Byongeye, uzakenera gusuzuma umubare wibice byahujwe kurubaho kuko bituma gusana bigoye kurangiza.

Itandukaniro: Umurongo umwe PCB Vs Igice kinini PCB

1. Uburyo bwo gukora

Igice kimwe PCB ikora inzira ndende yo gukora. Mubisanzwe, bikubiyemo gukoresha byinshiImashini ya CNCinzira yo gukora ikibaho. Inzira yose ikubiyemo gukata-gucukura-gushushanya-gushyira-kugurisha-kugurisha mask no gucapa.

Nyuma yaho, inyura mubuvuzi mbere yo kugeragezwa, kugenzurwa, no gupakira kubyoherezwa.

Hagati aho, PCBs nyinshi zirashirwaho binyuze muburyo budasanzwe. Harimo gutondekanya prereg hamwe nibikoresho fatizo hamwe hamwe binyuze mumuvuduko mwinshi n'ubushyuhe. Ibi byemeza ko umwuka utazafatwa hagati ya buri cyiciro. Na none, bivuze ko resin izatwikira abayobora kandi ibifatika bifata buri gice hamwe bigashonga kandi bigakira neza.

2. Ibikoresho

PCBs imwe-imwe kandi igizwe na PCBs ikorwa hifashishijwe ibyuma, FR-4, CEM, Teflon, nibikoresho bya polyimide. Nubwo bimeze bityo, umuringa nuguhitamo cyane.

3. Igiciro

Muri rusange, PCB imwe-imwe PCB ntabwo ihenze kuruta PCB nyinshi. Ibyo ahanini biterwa nibikoresho byakoreshejwe, igihe cyo gutanga, n'ubuhanga. Ibindi bintu bishobora kugira ingaruka kubiciro, harimo ingano, lamination, igihe cyo kuyobora, nibindi.

4. Gusaba

Mubisanzwe, PCBs imwe ikoreshwa mubikoresho byoroheje, mugihe PCBs nyinshi zirakoreshwa cyane mubuhanga buhanitse, nka terefone.

Guhitamo niba ukeneye PCBs imwe cyangwa nyinshi

Byagufasha mugihe wahisemo niba ibice byinshi cyangwa ibice bimwe byacapwe byumuzunguruko bisabwa kumushinga wawe. Noneho, suzuma ubwoko bwumushinga ufite nuburyo bukwiye. Ibi nibibazo bitanu ugomba kwibaza:

1.Ni uruhe rwego rw'imikorere nzakenera? Urashobora gukenera izindi nzego niba ari nyinshi.

2. Ingano ntarengwa y'ubutegetsi ni ubuhe? Ibibaho byinshi byemerera gukora byinshi mukarere gato.

3. Uha agaciro kuramba? Multi-layer ninziza nziza niba kuramba aribyingenzi.

4. Ningomba gukoresha angahe? Ikibaho kimwe ni cyiza kuri bije itarenze $ 500.

5. Ni ikihe gihe cyo kuyobora PCBs? Igihe cyo kuyobora kumwanya umwe wacapwe wumuzunguruko ni ngufi kurenza iy'ibibaho byinshi.

Ibindi bibazo bya tekiniki, nkibikorwa inshuro, ubucucike, nibimenyetso byerekana ibimenyetso, bizakenera gukemurwa. Ibi bibazo bizerekana niba ukeneye ikibaho gifite kimwe, bitatu, bine, cyangwa byinshi.
