Ubumenyi bwumurongo wa SMT / PCB

Shenzhen Chengyuan Industrial Automation Equipment Co., Ltd. itanga ibisubizo byumwuga nibikoresho byokoresha imashini zikoresha ubwenge bwa SMT.

Umushinga wa SMT, kugurisha ibicuruzwa bitagira isasu, kugurisha ibyuma bitagira isasu, imashini isiga amarangi ya PCB, imashini icapa, ifuru ikiza.

Ntagushidikanya ko icyapa cyumuzingo cyacapwe (PCB) nigikoresho cyibanze mu ikoranabuhanga ryabantu.

PCBs zahindutse uburyo bwo guhindura uburyo bwo gukora ibikoresho bya elegitoroniki.Mu bihe byashize, ibyo bikoresho bya elegitoroniki byubatswe byagombaga gusimbuzwa imbaho ​​zacapwe.Ibi ni ukubera ko imirimo myinshi izahuzwa ku kibaho.

Gereranya ikibaho cyumuzunguruko wa calculatrice 1968 hamwe nububiko bwa mudasobwa igezweho.

1. Ibara.

Ndetse kubantu bamwe batazi icyo PCB igamije, mubisanzwe bazi uko PCB isa.Nibura basa nkaho bafite uburyo bumwe gakondo, ni icyatsi.Icyatsi mubyukuri ni ibara ryibonerana ryabagurisha mask ikirahure.Nubwo izina rya masike yagurishijwe ari mask yo kugurisha, umurimo wacyo nyamukuru ni ukurinda uruziga rutwikiriwe nubushuhe n ivumbi.

Kubyimpamvu masike yo kugurisha ari icyatsi, impamvu nyamukuru nuko icyatsi aricyo gipimo cyo kurinda igisirikare.Ku nshuro yambere, PCBs mubikoresho bya gisirikare yakoresheje masike yo kugurisha mumurima kugirango irinde kwizerwa ryumuzunguruko.

Maskeri yo kugurisha iraboneka mumabara atandukanye, harimo umukara, umutuku, umuhondo, nibindi byinshi.Nyuma ya byose, icyatsi ntabwo ari inganda.

2. Ninde wahimbye PCB?

Ikibaho cyambere cyacapwe gishobora kuboneka uhereye kuri injeniyeri wo muri Otirishiya Charles Ducas mu 1920, watanze igitekerezo cyo gukoresha amashanyarazi hamwe na wino (gucapa insinga z'umuringa ku isahani yo hasi).Yakoresheje tekinoroji ya electroplating kugirango akore insinga hejuru yubushakashatsi kandi akora prototype ya PCB.

Insinga z'icyuma ku mbaho ​​z'umuzunguruko zari umuringa, umusemburo wa muringa na zinc.Ibi byavumbuwe bikuraho inzira igoye yo gukoresha insinga za elegitoroniki, byemeza imikorere yimikorere.Iyi nzira ntabwo yinjiye mubikorwa bifatika kugeza nyuma yintambara ya kabiri yisi yose.

3. Ikimenyetso.

Hano hari ibimenyetso byinshi byera kumurongo wicyatsi.Imyaka myinshi, abantu ntibasobanukiwe impamvu ibyo bicapo byera byiswe "silkscreen layers".Bakoreshwa cyane cyane kugirango bamenye amakuru yibice byumuzunguruko nibindi bikoresho bijyanye ninama yumuzunguruko.Aya makuru arashobora gufasha injeniyeri zumuzunguruko kugenzura ikibaho amakosa.
