1. PCB isifunda esifushane esidalwe ukugijima kothini

1. Ukuqhutshwa kwethini kubangelwe ukusebenza okungafanele ethangini lomuthi wefilimu eyehlayo;

2. Ipuleti elibuyise ifilimu liphakanyiswe ndawonye ukuze kudaleke ithini.

Okwesibili, i-PCB yesifunda emfushane ebangelwa ukugcwala okungcolile

1. Izinga lokulawulwa kwe-potching parameter control lithinta ngqo ikhwalithi yokuchopha.

3. Isifunda se-PCB microshort esibonakalayo

1. Isifunda esincane esifushane esibangelwe ukuklwebheka ifilimu iMyra emshinini wokuchayeka;

2, ukuvezwa kwepuleti ekuklwebheni kwengilazi okubangelwe umugqa wesifunda esifushane.

Okwesine, isiqeshana sefilimu se-PCB esifushane

1. Ungqimba olwa nokumboza luncane kakhulu. Lapho kufakwa, ukumboza kudlula ukushuba kwefilimu, kwakhiwa ifilimu yesiqeshana, ikakhulukazi izikhala zemigqa emincane, kuba lula kakhulu ukudala isifunda esifushane sefilimu esiqeshwayo.

2. Ukusatshalaliswa okungalingani kwemidwebo yepuleti. Enkambeni ye-electroplating graphic, ukumbozwa kwemigqa ehlukanisiwe kudlula ukushuba kwefilimu ngenxa yamandla aphezulu, okuholele ekujikelezeni okufushane okubangelwa ukucindezela ifilimu.

Isihlanu, isifunda se-PCB microshort esingabonakali

Isifunda esingabonakali esincane esifushane yinkinga ekhathaza kakhulu inkampani yethu isikhathi eside futhi kube yinkinga enzima kakhulu ukuxazulula. Cishe ama-50% wamabhodi aqediwe anezinkinga esivivinyweni anjalo yizinkinga zesifunda ezincane. Isizathu esikhulu ukuthi kunezintambo zensimbi noma izinhlayiya zensimbi ezingabonakali ngeso lenyama esikhaleni somugqa.

Isithupha, i-PCB yesikhashana emisiwe

Isizathu esiyinhloko ukuthi ulayini wefilimu uklwebhiwe noma kukhona ukuvimba imfucumfucu kupuleti lesikrini eligcotshisiwe, futhi indawo eboshwe anti-enamathela indawo yethusi elungisiwe iveze ukuholela kusifunda esifushane.

Isikhombisa, bhala isifunda esifushane se-PCB

1, ukumanzisa ifilimu okumanzi ngemuva kokuqala, ukusebenza okungafanele okubangelwe ukuklwebheka ifilimu.

2. Ipuleti lomshini elikhulayo lisematasa kakhulu ukubanga ukushayisana nokunwaya phakathi kwepuleti nepuleti.

3. Ukuklwebheka kubangelwa ukuthatha ipuleti okungafanele ngesikhathi sokuqothula, ukusebenza okungafanele ngesikhathi sokufakwa kwe-splint, ukusebenza okungafanele ngesikhathi sokuphathwa kwepuleti ngaphambi komugqa wezandla.
