Inshamake ya PCB ishushanya ingingo zingenzi: ibintu byinshi ugomba kwitondera

Igishushanyo mbonera cyumuzingo (PCB) nigishushanyo cyingenzi mugutezimbere ibicuruzwa bya elegitoroniki. Igishushanyo cyiza cya PCB ntigishobora gusa kunoza imikorere no kwizerwa kumuzunguruko, ariko kandi kigabanya ibiciro byumusaruro nibibazo byo kubungabunga. Ibikurikira ningingo nyinshi nibintu bigomba kwitabwaho mugushushanya PCB.

1. Igishushanyo mbonera cyumuzingi

Mbere yo gukomeza imiterere ya PCB, ugomba kubanza kuzuza igishushanyo mbonera cyumuzingi. Iyi ntambwe ntabwo ari ishingiro ryibishushanyo bya PCB gusa, ahubwo nibisabwa kugirango tumenye imikorere yumuzunguruko n'imikorere. Mugihe utegura igishushanyo mbonera cyumuzingi, ugomba kwitondera ingingo zikurikira:

Sobanura imikorere n'ibisabwa: Sobanukirwa neza imikorere n'ibikorwa by'umuzunguruko kandi urebe ko igishushanyo gishobora kuzuza ibyo bisabwa.

Hitamo ibice bikwiye: Hitamo ibice bikwiye bishingiye kumikorere yumuzunguruko, urebye ibintu nkibikorwa bigize ibice, gupakira, nigiciro.

Shyira akamenyetso ku bimenyetso n'ibipimo: Menya neza ko ibirango n'ibigize ku gishushanyo mbonera bisobanutse neza kandi neza kugira ngo byorohereze imiterere ya PCB no gukemura.

2. Imiterere ishyize mu gaciro

Imiterere yibigize ni igice cyingenzi cyo kwemeza imikorere ya PCB. Imiterere ikeneye gusuzuma byimazeyo ibintu byinshi nkibikorwa byumuzunguruko, ubuziranenge bwibimenyetso, imicungire yubushyuhe, nibindi. Dore bimwe mubitekerezo:

Gutandukanya imikorere: Gabanya uruziga mumikorere ikora hanyuma ushire ibice bigize module imwe ikora hamwe kugirango ugabanye inzira zohereza ibimenyetso.

Ubunyangamugayo bwibimenyetso: Imirongo yihuta yihuta igomba kuba ngufi kandi itaziguye bishoboka kugirango wirinde kwivanga. Imirongo yingenzi yibimenyetso nkumurongo wamasaha, gusubiramo imirongo, nibindi bigomba kubikwa kure y urusaku.

Imicungire yubushyuhe: Ibice bifite ingufu nyinshi bigomba gukwirakwizwa kimwe, kandi hagomba gusuzumwa ibibazo byo gukwirakwiza ubushyuhe.

3. Amategeko agenga inzira

Inzira niyindi miyoboro yingenzi mugushushanya kwa PCB. Dore ingingo zimwe ugomba kumenya mugihe ugenda:

Ubugari bwumurongo nintera: Hitamo ubugari bwumurongo ukwiranye nubunini buriho kugirango umenye neza ko umurongo ushobora kwihanganira umuyaga uhuye. Komeza intera ihagije hagati yumurongo wibimenyetso bitandukanye kugirango wirinde kubangamira ibimenyetso.

Umubare w'insinga: Inzira zisanzwe zikenera insinga nyinshi.

Irinde impinduka zikarishye: Irinde impinduka zikarishye mugihe ugenda, kandi ugerageze gukoresha impinduramatwara ya dogere 45 kugirango ugabanye ibimenyetso byerekana no kwivanga.

4. Gutanga amashanyarazi no gushushanya

Gutanga amashanyarazi hamwe nigishushanyo mbonera nicyo kintu cyambere cyibanze mu gishushanyo cya PCB, bigira ingaruka ku buryo butajegajega hamwe nubushobozi bwo kurwanya interineti. Ibikurikira nibitekerezo byimbaraga nigishushanyo mbonera:

Amashanyarazi nubutaka: Koresha amashanyarazi yigenga hamwe nubutaka kugirango ugabanye inzitizi hagati yumuriro nubutaka no kuzamura ubwiza bwamashanyarazi.

Kurangiza ubushobozi: Tegura capacitor hafi ya pin kugirango ushungure urusaku rwinshi kandi urebe neza ko amashanyarazi ahamye.

Impamvu y'ubutaka: irinde igishushanyo mbonera kandi ugabanye amashanyarazi. Insinga zubutaka kumirongo yerekana ibimenyetso igomba kuba ngufi kandi itaziguye bishoboka.

5. Igishushanyo cya EMI / EMC

Kwivanga kwa Electromagnetic (EMI) hamwe no guhuza amashanyarazi (EMC) ni urufunguzo rwo kwemeza ko PCBs ikora neza mubidukikije bigoye bya electroniki. Ibikurikira nibitekerezo bya EMI / EMC:

Igishushanyo cyo gukingira: Shira ibimenyetso byoroshye hamwe n urusaku rwinshi kugirango ugabanye amashanyarazi.

Igishushanyo mbonera: Ongeramo akayunguruzo kumashanyarazi no kumurongo wibimenyetso kugirango ushungure ibimenyetso byurusaku kandi utezimbere amashanyarazi.

Igishushanyo mbonera: Igishushanyo cyiza gishobora guhagarika neza imiyoboro ya electromagnetiki no kunoza ubushobozi bwo kurwanya interineti.

6. Gukora no Kwirinda Inteko

Igishushanyo cya PCB ntigomba gutekereza gusa kumikorere yumuzunguruko, ahubwo inareba uburyo bwo gukora no guteranya. Dore ingingo zimwe ugomba kumenya mugihe cyo gukora no guterana:

Ibikoresho bipakira hamwe nintera: Hitamo ibice bisanzwe bipfunyitse kugirango wemeze umwanya uhagije wo guterana kugirango byoroshye gusudira no kubungabunga.

Igishushanyo mbonera cyibizamini: Tegura amanota yikizamini kuri node kugirango byorohereze ibizamini byumuzunguruko no gukemura ibibazo.

Igikorwa cyo kubyaza umusaruro: Sobanukirwa kandi ukurikize uburyo bwihariye bwibikorwa bya PCB kugirango umenye neza ko igishushanyo cyujuje ibisabwa ninganda.

mu gusoza

Igishushanyo cya PCB ni inzira igoye kandi yoroshye, ikubiyemo ibintu byinshi nkibishushanyo mbonera byumuzunguruko, imiterere yibigize, amategeko agenga inzira, gutanga amashanyarazi no gushushanya, igishushanyo cya EMI / EMC, gukora no guteranya. Buri kintu cyose gisaba kwitabwaho neza nabashushanyije kugirango bashushanye ikibaho cyumuzunguruko gifite imikorere myiza, ituze kandi yizewe. Binyuze mu ncamake yiyi ngingo, nizere ko nzatanga ibisobanuro nubuyobozi kubashushanya PCB kugirango barusheho kunoza imikorere nubushakashatsi bwa PCB.
