Nshobora gukora prototype amashanyarazi PCB?

Intangiriro:

Mwisi nini ya elegitoroniki, ibikoresho bitanga ingufu bigira uruhare runini mugutanga ingufu zisabwa mubikoresho bitandukanye. Haba mu ngo zacu, mu biro cyangwa mu nganda, imbaraga ziri hose. Niba uri umuyoboke wa elegitoroniki cyangwa umunyamwuga ushaka kwihangira amashanyarazi, ushobora kwibaza niba bishoboka gukora prototype yamashanyarazi yacapwe (PCB).Muri iyi blog, tuzasesengura ibishoboka ningorane zo gutanga amashanyarazi PCB prototyping nuburyo bwo kuyishyira mubikorwa.

Wige ibijyanye na prototyping ya PCB:

Mbere yuko tujya muburyo bwihariye bwo gutanga amashanyarazi PCB prototyping, reka tubanze dusobanukirwe na prototyping ya PCB. Ikibaho cyumuzunguruko cyacapwe (PCB) ni isahani iringaniye ikozwe mubintu bitayobora (mubisanzwe fiberglass) hamwe n'inzira ziyobora zometse cyangwa zacapwe hejuru yacyo. PCB ni ishingiro ryibikoresho bya elegitoronike bishyirwaho kandi bigurishwa, bitanga ubufasha bwamashanyarazi hamwe nu mashanyarazi.

PCB prototyping ninzira yo gukora prototype cyangwa icyitegererezo cya PCB kugirango igerageze kandi yemeze igishushanyo kibanziriza umusaruro mwinshi. Iremera abashushanya gusuzuma imikorere, ibishoboka, nigikorwa cyumuzunguruko wabo bitabaye ngombwa ikiguzi ningaruka zijyanye numusaruro wuzuye. Prototyping ifasha kumenya no gukosora inenge cyangwa impinduka zose zikenewe mugushushanya hakiri kare cyiterambere, amaherezo bikavamo ibicuruzwa byanyuma kandi byiza.

Ibibazo byo gutanga amashanyarazi:

Gushushanya no gukoresha ibikoresho bitanga ingufu birashobora kugorana kubera ibintu bitandukanye. Ubwa mbere, ibikoresho bitanga ingufu mubisanzwe bisaba imbaraga zingirakamaro nka transformateur, ikosora, hamwe na voltage igenzura. Kwinjiza ibyo bice kuri PCB nto birashobora kugorana kuko bisaba gutegura neza imiterere nuburyo bwo gukwirakwiza ubushyuhe.

Byongeye kandi, ibikoresho by'amashanyarazi bigomba guhangana n’umuvuduko mwinshi n’umuyaga, byongera ibyago by’urusaku rw’amashanyarazi, kwivanga kwa electronique (EMI) n’ingaruka zishobora guhungabanya umutekano. PCB prototyping isaba tekinoroji ikwiye yo gukingira, gukingira, hamwe nuburyo bwo kwigunga kugirango imikorere yizewe, itekanye.

Byongeye kandi, ibishushanyo mbonera bitanga amashanyarazi akenshi byashizweho hashingiwe kubisabwa byihariye nkurwego rwa voltage, ibipimo biriho, hamwe nibisohoka bihamye. Prototyping yemerera abashushanya guhuza neza ibipimo no kunoza imikorere yumuriro kubyo bagenewe, yaba ibikoresho bya elegitoroniki byabaguzi, imashini zinganda cyangwa urundi rwego.

Amashanyarazi yo gutanga amashanyarazi:

Ku bijyanye no gutanga amashanyarazi PCB prototyping, abashushanya bafite amahitamo menshi ukurikije ibyo basabwa nubuhanga. Reka dusuzume uburyo bukunzwe:

1. Mugihe imbaho ​​zitanga ibyoroshye kandi byoroshye, zifite ubushobozi buke bwo gukoresha ingufu kandi ntibishobora kuba bikwiranye nimbaraga nyinshi.

2. Stripboard prototyping: Stripboard, izwi kandi nka veroboard cyangwa Copperboard, itanga igisubizo kirambye kuruta ikibaho. Ziranga umuringa wabanjirijwemo ibice bishobora kugurishwa. Stripboard itanga ingufu nziza kandi irashobora kwakira amashanyarazi hagati.

3 Ifasha igishushanyo mbonera, gushyira ibice, hamwe no guhitamo inzira ikenewe kubisabwa ingufu. Abashushanya barashobora gukoresha ibikoresho bitandukanye bya software ya PCB kugirango bazane ibitekerezo byabo byamashanyarazi mubuzima no gukora prototypes ijyanye nibyo bakeneye.

Ibyiza byo gutanga amashanyarazi PCB prototyping:

Amashanyarazi PCB prototyping itanga abashushanya ibyiza byinshi:

1.

2.

Mu gusoza:

Gutanga amashanyarazi PCB prototyping ntabwo bishoboka gusa, ariko kandi ni byiza cyane. Ifasha abashushanya gutsinda ibibazo, guhuza neza ibishushanyo byabo, no kunoza imikorere yo gutanga amashanyarazi. Waba wahisemo imigati cyangwa progaramu ya PCB yihariye, ubushobozi bwo kugerageza no kwemeza igishushanyo cyawe mbere yumusaruro mwinshi ni ntagereranywa. Niba rero ufite igitekerezo cyo gutanga amashanyarazi, prototype ubungubu uyishyire mubikorwa. Ibyiza bya prototyping!
