Gushyira hamwe ni iki?
Stack-up bivuga gutondekanya ibice byumuringa no kubika ibice bigize PCB mbere yo gushushanya imiterere.Mugihe urwego rwibikoresho bigufasha kubona umuzenguruko mwinshi kurubaho rumwe unyuze mubice bitandukanye byubuyobozi bwa PCB, imiterere yubushakashatsi bwa PCB butanga izindi nyungu nyinshi:
• Ikibaho cya PCB kirashobora kugufasha kugabanya intege nke zumuzunguruko wurusaku rwo hanze kimwe no kugabanya imirasire no kugabanya impedance hamwe ninzira nyabagendwa kumiterere yihuta ya PCB.
• Igice cyiza cya PCB gishobora kandi kugufasha kuringaniza ibyo ukeneye kuburyo buhendutse, uburyo bwo gukora neza hamwe nimpungenge zijyanye nibibazo byubusugire bwibimenyetso
• Iburyo bukwiye bwa PCB burashobora kuzamura Electromagnetic Guhuza ibishushanyo byawe.
Bizakubera byiza cyane kugirango ukurikirane iboneza rya PCB kubikoresho byawe byacapwe byumuzunguruko.
Kuri PCB nyinshi, ibice rusange birimo indege yubutaka (indege ya GND), indege yimbaraga (indege ya PWR), hamwe nibimenyetso byimbere.Dore icyitegererezo cyibice 8 bya PCB.
ANKE PCB itanga imbaho nyinshi zumuzingi / murwego rwo hejuru rwumuzunguruko uri hagati ya 4 na 32, uburebure bwikibaho kuva 0.2mm kugeza kuri 6.0mm, uburebure bwumuringa kuva kuri 18 mm kugeza kuri 210 mm (0.5oz kugeza 6oz), uburebure bwumuringa bwimbere kuva kuri 18 mm kugeza kuri 70 mm (0.5 oz kugeza 2oz), n'umwanya muto hagati ya 3mil.
