Nigute ushobora gukora prototype PCB ifite urusaku ruke rusabwa

Gukoresha prototyp yicapiro ryumuzunguruko (PCB) hamwe nibisabwa urusaku ruke birashobora kuba umurimo utoroshye, ariko birashoboka rwose ko bigerwaho hamwe nuburyo bwiza no gusobanukirwa amahame nubuhanga burimo.Muri iyi nyandiko ya blog, tuzasesengura intambwe nibitekerezo bishobora kugufasha gukora prototypes ya PCB-urusaku ruke.Reka rero, dutangire!

1. Sobanukirwa urusaku muri PCBs

Mbere yo gucengera muri prototyping, ni ngombwa kumva urusaku icyo aricyo n'ingaruka kuri PCB.Muri PCB, urusaku bivuga ibimenyetso by'amashanyarazi bidakenewe bishobora gutera intambamyi no guhagarika inzira yerekana ibimenyetso.Urusaku rushobora guterwa nimpamvu zitandukanye, zirimo kwivanga kwa electromagnetic (EMI), imirongo yubutaka, hamwe no gushyira ibice bidakwiye.

2. Hitamo ibice byo gutezimbere urusaku

Guhitamo ibice nibyingenzi kugabanya urusaku muri prototypes ya PCB.Hitamo ibice byabugenewe kugirango ugabanye urusaku rw urusaku, nkibikoresho byongera urusaku ruto na filtri.Byongeye kandi, tekereza gukoresha ibikoresho byo hejuru (SMDs) aho gukoresha ibice, kuko bishobora kugabanya ubushobozi bwa parasitike na inductance, bityo bigatanga urusaku rwiza.

3. Gukosora ibice byashyizwe hamwe

Gutegura neza gushyira ibice kuri PCB birashobora kugabanya cyane urusaku.Itsinda ryibice byunvikana urusaku hamwe kandi kure yimbaraga nyinshi cyangwa ibice byinshi.Ibi bifasha kugabanya ibyago byo guhuza urusaku hagati yibice bitandukanye byumuzunguruko.Mugihe ugenda, gerageza gutandukanya ibimenyetso byihuta nibimenyetso byihuta kugirango wirinde ibimenyetso bitari ngombwa.

4. Impamvu nimbaraga

Gukwirakwiza neza no gukwirakwiza ingufu ningirakamaro muburyo bwa PCB butagira urusaku.Koresha ubutaka bwabigenewe hamwe nimbaraga zindege kugirango utange inzira-yihuta yo kugaruka kumuyoboro mwinshi.Ibi bifasha kugabanya ihindagurika rya voltage kandi bikerekana ibimenyetso bihamye byerekana, bigabanya urusaku mubikorwa.Gutandukanya ibigereranyo hamwe nibimenyetso bya digitale bigabanya cyane ibyago byo kwanduza urusaku.

5. Ikoranabuhanga ryo kugabanya urusaku

Gushyira mubikorwa tekinike yo kugabanya urusaku birashobora gufasha kunoza imikorere yurusaku muri prototypes ya PCB.Kurugero, ukoresheje ubushobozi bwa decoupling capacator kumurongo wamashanyarazi kandi hafi yibikoresho bikora birashobora guhagarika urusaku rwinshi.Gukoresha tekinike yo gukingira, nko gushyira uruziga rukomeye mubyuma cyangwa kongeramo ingabo ikingira, birashobora kandi kugabanya urusaku rujyanye na EMI.

6. Kwigana no kugerageza

Mbere yo gukora prototype ya PCB, imikorere yayo igomba kwigana no kugeragezwa kugirango imenye kandi ikemure ibibazo byose bishobora guterwa nurusaku.Koresha ibikoresho byo kwigana kugirango usesengure uburinganire bwibimenyetso, konte yibice bya parasitike, kandi usuzume ikwirakwizwa ry urusaku.Byongeye kandi, ibizamini bikora birakorwa kugirango PCB yujuje ibyangombwa bisabwa-urusaku ruto mbere yo gukomeza umusaruro.

Muri make

Prototyping PCBs ifite urusaku ruke bisaba gutegura neza no gushyira mubikorwa tekinike zitandukanye.Urashobora kugabanya urusaku muburyo bwa PCB muguhitamo ibice byogutezimbere urusaku, ukitondera gushyira ibice hamwe nu murongo, guhuza indege nubutaka bwamashanyarazi, gukoresha tekinike yumuzunguruko ugabanya urusaku, no kugerageza prototypes neza.
