Uyinki we-PCB ubhekisela kuyinki osetshenziswa ku-PCB. Manje ake sabelane nawe ngezici nezinhlobo zikayinki we-PCB?

1. Izici zikayinki we-PCB

1-1. I-viscosity kanye ne-thixotropy
Enqubweni yokukhiqiza amabhodi esekethe aphrintiwe, ukuphrinta kwesikrini kungenye yezinqubo ezibalulekile nezibalulekile. Ukuze uthole ukwethembeka kokukhiqizwa kwesithombe, uyinki kufanele ube ne-viscosity enhle kanye ne-thixotropy efanelekile.
1-2. Ubuhle
Ama-pigments nama-mineral fillers kayinki we-PCB ngokuvamile aqinile. Ngemuva kokugaya okuhle, usayizi wezinhlayiyana zabo aweqi ama-microns angu-4/5, futhi bakhe isimo sokugeleza se-homogenized ngendlela eqinile.

2. Izinhlobo zamayinki e-PCB

Oyinki be-PCB bahlukaniswe ikakhulukazi izigaba ezintathu: isifunda, imaski ye-solder kanye noyinki wesikrini sikasilika.

2-1. Uyinki wesifunda usetshenziswa njengesithiyo sokuvimbela ukugqwala kwesekethe. Ivikela umugqa ngesikhathi sokuqopha. Ivamise ukuzwela uketshezi; Kunezinhlobo ezimbili: ukumelana nokugqwala kwe-acid kanye ne-alkali corrosion resistance.
2- 2. I-ink ye-solder resist is painted on the circuit ngemva kokuba isekethe isiqediwe njengomugqa wokuvikela. Kunezinhlobo ze-photosensitive eziwuketshezi, zokuphulukisa ukushisa kanye nezinhlobo eziqinisa i-UV. I-bonding pad igcinwe ebhodini ukuze kube lula ukushiselwa kwezingxenye futhi idlale indima yokuvimbela nokuvimbela i-oxidation.
2-3. Uyinki wesikrini sikasilika usetshenziselwa ukumaka indawo engaphezulu yebhodi, njengophawu lwezingxenye, ngokuvamile ezimhlophe.

Ngaphezu kwalokho, kukhona abanye oyinki, njengoyinki wokunamathisela okhumukayo, uyinki wokunamathisela wesiliva, njll.
