Gukemura 8 Layeri Pcb yerekana ubunyangamugayo nibibazo byo gukwirakwiza amasaha

Niba ufite uruhare muri elegitoroniki hamwe nu mbaho ​​zicapye (PCBs), birashoboka ko wahuye nibibazo bisanzwe hamwe nuburinganire bwibimenyetso no gukwirakwiza amasaha. Ibi bibazo birashobora kugorana kubitsinda, ariko ntugire ubwoba!Muri iyi nyandiko ya blog, tuzareba uburyo bwo gukemura uburinganire bwibimenyetso nibibazo byo gukwirakwiza amasaha kuri PCB-8. Kugirango tugufashe murugendo rwawe, turamenyekanisha Capel, isosiyete ifite uburambe bwimyaka 15 mubikorwa bya PCB no gutanga igenzura ryiza.

Ubunyangamugayo bwibimenyetso nigice cyingenzi cyigishushanyo cya PCB kuko cyemeza ko ibimenyetso byamashanyarazi byoherejwe muri PCB bitangirika cyangwa ngo bigoreke.Iyo ibibazo byubusugire bwibimenyetso bibaye, ruswa yamakuru, amakosa yigihe, ndetse na sisitemu yananiwe. Kubwibyo, ni ngombwa gukemura neza ibyo bibazo.

Gukwirakwiza amasaha, kurundi ruhande, bivuga inzira yo kohereza ibimenyetso byamasaha muri PCB.Gukwirakwiza amasaha neza ni ngombwa muguhuza hamwe nigihe muri sisitemu ya elegitoroniki. Gukwirakwiza amasaha mabi birashobora gutera ibice bitandukanye gukora nabi, biganisha kuri sisitemu kunanirwa cyangwa kunanirwa byuzuye.

Noneho, reka twibire muburyo bumwe nubuyobozi bwo gukemura ibyo bibazo:

1. Igishushanyo mbonera cyo gutondekanya: Guteganya neza gutondekanya ibice ni ishingiro ryo kwemeza ibimenyetso byuzuye no gukwirakwiza amasaha. PCBs 8-layer itanga ihinduka ryinshi mugushushanya ingufu nindege zubutaka, bifasha kugabanya urusaku no gutanga ubuziranenge bwibimenyetso.Tekereza gukoresha imbaraga nindege zitandukanye kuri buri kimenyetso cyerekana no gushyira mubikorwa indege yizewe.

2. Kugenzura Impedance: Kugumana inzitizi zagenzuwe muri PCB ningirakamaro kugirango ugaragaze ubunyangamugayo. Koresha igikoresho cyo kubara impedance kugirango umenye ubugari bwumwanya hamwe nintera isabwa kumurongo wohereza ukurikije ibikoresho bya PCB hamwe na stackup.Hamwe nimyaka 15 yuburambe bwa PCB, Capel irashobora gutanga ubuyobozi bwumwuga kandi ikagenzura neza impedance.

3. Gukoresha ibimenyetso bigufi bigabanya ibimenyetso byo gutinda no kugabanya urusaku.Koresha ibimenyetso bitandukanye kubimenyetso byihuta kugirango wongere ubudahangarwa bw'urusaku. Byongeye kandi, uburebure bujyanye nubuhanga bukoreshwa mukugabanya igihe nigihe cyo guhuza ibibazo.

4.Kurandura ubushobozi butanga inzira-yimbogamizi kubutaka, kugabanya ihindagurika rya voltage no kwirinda kugoreka ibimenyetso.

5. Gukingira EMI: Kwivanga kwa Electromagnetic (EMI) birashobora kugira ingaruka zikomeye kubudakemwa bwikimenyetso no gukwirakwiza amasaha.Gushyira mubikorwa tekinike yo gukingira EMI, nko gukoresha ingabo ikingira cyangwa kongeramo ibimenyetso byayobora, birashobora kugabanya ingaruka za EMI no kunoza imikorere muri rusange.

Noneho ko tumaze gusuzuma ibisubizo bifatika byerekana ibimenyetso byubusugire nibibazo byo gukwirakwiza amasaha, reka tumenye Capel - isosiyete ifite uburambe bunini kandi igenzura ubuziranenge mubikorwa bya PCB.Hamwe nimyaka 15 yinzobere mu nganda, Capel yumva ibintu bigoye bya PCB kandi irashobora gutanga ibisubizo byizewe kumushinga wawe.

Capel yiyemeje kugenzura ubuziranenge bukomeye kugirango buri PCB bakora zujuje ubuziranenge.Kuva mugice cyambere cyo gushushanya kugeza kumusaruro wanyuma, Capel ikoresha uburyo bukomeye bwo kugerageza no kugenzura kugirango ikureho ibimenyetso byose bishobora kuba ubuziranenge cyangwa ibibazo byo gukwirakwiza amasaha. Itsinda ryabo ba injeniyeri b'inararibonye barashobora gutanga ubushishozi nubuyobozi kugirango umushinga wawe PCB ugende neza.

Muri make, gukemura ubuziranenge bwibimenyetso nibibazo byo gukwirakwiza amasaha kuri PCB igizwe na 8 bisaba igenamigambi ryitondewe, tekinike nziza yo gushushanya, hamwe nubuhanga bukwiye.Gushyira mubikorwa ingamba nko guhuza ibice, kubika inzitizi zagenzuwe, gukoresha uburyo bukwiye bwo kuyobora, no gushyiramo uburyo bwo gukingira EMI birashobora kunoza imikorere ya PCB. Hamwe numufatanyabikorwa wizewe nka Capel, urashobora kwizeza ko PCB yawe izakorwa hamwe nubuziranenge kandi bwuzuye. Noneho, wemere ibisubizo kandi utume umushinga wawe wa PCB utaha ugenda neza!
