SMT || Inama zo kubaka neza PCB ibice byihariye

Ku kibaho cya PCB, mubisanzwe dukoresha ibice byingenzi bikoreshwa byingenzi, ibice byingenzi mumuzunguruko, ibice byahungabanijwe byoroshye, ibice bya voltage nyinshi, ibyingenzi bifite agaciro gakomeye hamwe nibice bimwe bitahuje ibitsina byitwa ibice byihariye. Imiterere yo gusura ibi bice byihariye bisaba gusesengura neza. Kuberako gushyira bidakwiye ibyo bice byihariye bishobora kuganisha kumakosa yo guhuza imirongo hamwe namakosa yubusugire bwibimenyetso, bikavamo ikibaho cyumuzunguruko PCB cyose ntigishobora gukora.

Mugihe utegura uburyo bwo gushyira ibice byihariye, banza urebe ubunini bwa PCB. Iyo ingano ya PCB ari nini cyane, umurongo wo gucapa ni muremure cyane, impedance iriyongera, kurwanya byumye bigabanuka, kandi ikiguzi cyiyongera. Niba ari nto cyane, gusohora ubushyuhe ntabwo ari byiza, kandi imirongo iherekejwe irashobora kwivanga.

Nyuma yo kumenya ingano ya PCB, menya umwanya wa kare yibice byihariye. Hanyuma, ibice byose byumuzunguruko bitunganijwe ukurikije igice gikora. Umwanya wibice byihariye ugomba gukurikiza amahame akurikira mugihe utegura:

Ihame ryimiterere yihariye

1. Gabanya ihuriro hagati yumurongo mwinshi cyane bishoboka kugirango ugabanye ibipimo byo gukwirakwiza no guhuza amashanyarazi hagati yandi. Ibice byoroshye ntibigomba kuba hafi cyane, kandi ibyinjira nibisohoka bigomba kuba kure cyane bishoboka.

. Ibice byinshi bya voltage bigomba gushyirwa kure hashoboka kugirango amaboko atagera.

3. Ibigize bipima ibirenga 15g birashobora gukosorwa hamwe na brake hanyuma bigasudwa. Ibi bikoresho biremereye kandi bishyushye ntibigomba gushyirwa ku kibaho cy’umuzunguruko, ahubwo bigomba gushyirwa ku isanduku nkuru yo hasi, kandi bigomba gutekereza ku gukwirakwiza ubushyuhe. Shira ibice bishyushye kure yibice bishyushye.

4. Kubijyanye nimiterere yibice bishobora guhinduka nka potentiometero, inductors zishobora guhinduka, capacator zihinduka hamwe na microswitches, ibisabwa byuburyo bwubuyobozi bwose bigomba kwitabwaho. Niba imiterere yemerera, bimwe mubisanzwe byakoreshejwe bigomba gushyirwa mumwanya byoroshye kubiganza. Imiterere yibigize igomba kuringanizwa, yuzuye, kandi ntabwo iremereye hejuru.

Intsinzi yibicuruzwa, kimwe nukwitondera ubuziranenge bwimbere. Ariko urebye ubwiza muri rusange, byombi birasa neza na PCB kugirango ube ibicuruzwa byiza.
