Ikibaho cyumuzunguruko cyinshi gisobanurwa nkibice 10-20 cyangwa byinshi byo murwego rwohejuru rwumuzunguruko wumuzunguruko, bigoye gutunganya kuruta imbaho gakondo zumuzunguruko kandi bisaba ubuziranenge kandi bukomeye.Ahanini ikoreshwa mubikoresho byitumanaho, seriveri zohejuru, ibikoresho bya elegitoroniki yubuvuzi, indege, kugenzura inganda, igisirikare nizindi nzego.Mu myaka yashize, isoko rikenewe ku mbaho z’umuzunguruko nyinshi mu bijyanye n’itumanaho, sitasiyo fatizo, indege, n’igisirikare biracyakomeye.
Ugereranije nibicuruzwa gakondo bya PCB, imbaho nyinshi zumuzunguruko zifite ibiranga ikibaho kibyibushye, ibice byinshi, imirongo yuzuye, byinshi binyuze mumyobo, ingano nini nini, hamwe na dielectric layer.Ibisabwa mu mibonano mpuzabitsina ni byinshi.Uru rupapuro rusobanura muri make ingorane nyamukuru zo gutunganya zagaragaye mu musaruro w’urwego rwo hejuru rw’umuzunguruko, kandi rugaragaza ingingo zingenzi zo kugenzura ibikorwa byingenzi by’ibikorwa by’ibicuruzwa by’umuzunguruko.
1. Ingorane zo guhuza ibice
Kubera umubare munini wibice muburyo butandukanye bwumuzunguruko, abakoresha bafite ibisabwa byinshi kandi bisabwa kugirango kalibibasi ya PCB.Mubisanzwe, kwihanganira guhuza ibice bikoreshwa kuri microni 75.Urebye ubunini bunini bwibice byinshi byumuzunguruko, ubushyuhe bwo hejuru nubushuhe mumahugurwa ahindura ibishushanyo, gutondekanya dislocation byatewe no kudahuza imbaho zitandukanye, hamwe nuburyo bwo guhuza imyanya, kugenzura kugenzura ibice byinshi ikibaho cyumuzunguruko kirakomeye kandi kiragoye.

2. Ingorane zo gukora imiyoboro yimbere
Ikibaho cyumuzunguruko cyinshi gikoresha ibikoresho byihariye nka TG ndende, umuvuduko mwinshi, inshuro nyinshi, umuringa mwinshi, hamwe nuduce duto twa dielectric, ibyo bikaba byashyize imbere ibisabwa cyane mubikorwa byimbere byimbere no kugenzura ingano yubushakashatsi.Kurugero, ubunyangamugayo bwogukwirakwiza ibimenyetso byongera ingorane zo guhimba imbere.
Ubugari n'umurongo bitandukanijwe ni bito, bifunguye kandi bigufi byongeweho, imirongo migufi yongeweho, kandi igipimo cyo gutsinda ni gito;hari ibimenyetso byinshi byerekana imirongo yoroheje, kandi amahirwe yo gutahura AOI mumurongo wimbere ariyongera;ikibaho cyimbere cyimbere kiroroshye, cyoroshye kubyimba, kugaragara nabi, kandi byoroshye kugorama mugihe imashini ikora;Isahani yo murwego rwohejuru ahanini ni imbaho za sisitemu, ingano yikigero ni kinini, kandi ikiguzi cyo gusiba ibicuruzwa ni kinini.
3. Ingorane zo Gukora Compression
Ibibaho byinshi byimbere byimbere hamwe nibibaho byabigenewe byashyizwe hejuru, byerekana gusa ibibi byo kunyerera, gusibanganya, imyanda ya resin hamwe nibisigazwa bya bubble mugukora kashe.Mugushushanya imiterere ya laminate, kurwanya ubushyuhe, kurwanya umuvuduko, ibirimo kole hamwe nuburinganire bwa dielectrici yibikoresho bigomba gutekerezwa byuzuye, kandi hagomba gutegurwa gahunda yumvikana yibice byinshi byumuzunguruko.
Bitewe numubare munini wibyiciro, kwaguka no kugabanya kugenzura hamwe nubunini bwa coefficient yubunini ntibishobora gukomeza guhuzagurika, kandi urwego ruto rwimikorere rworoshye rworoshye, ibyo bigatuma habaho kunanirwa kwipimisha ryizerwa.
4. Ingorane zo gukora inganda
Gukoresha TG ndende, umuvuduko mwinshi, inshuro nyinshi, hamwe nicyuma cyumuringa cyihariye cyongera ingorane zo gucukura ubukana, burrs burles no kwanduza.Umubare wibice ni munini, ubunini bwumuringa hamwe nubunini bwa plaque birundanyije, kandi igikoresho cyo gucukura kiroroshye kumeneka;ikibazo cyo kunanirwa kwa CAF cyatewe na BGA yagabanijwe cyane hamwe nu mwanya muto wurukuta;ikibazo cyo gucukura oblique cyatewe nubunini bworoshye bwa plaque.Ikibaho cyumuzunguruko wa PCB
