Enke ea PCB e bolela enke e sebelisoang ho PCB. Joale ha re arolelaneng le uena litšobotsi le mefuta ea enke ea PCB?

1. Litšobotsi tsa enke ea PCB

1-1. Viscosity le thixotropy
Ts’ebetsong ea ho etsa liboto tsa potoloho tse hatisitsoeng, khatiso ea skrine ke e ‘ngoe ea lits’ebetso tsa bohlokoa le tsa bohlokoa. E le hore u fumane botšepehi ba ho hlahisa setšoantšo, enke e tlameha ho ba le viscosity e ntle le thixotropy e loketseng.
1-2. Bokhabane
Li-pigments le li-mineral fillers tsa li-inks tsa PCB hangata li tiile. Ka mor’a ho sila hantle, boholo ba tsona ha bo fete li-microns tse 4/5, ‘me li theha boemo ba ho phalla ha homogenized ka mokhoa o tiileng.

2. Mefuta ea li-inks tsa PCB

Li-inks tsa PCB li arotsoe haholo ka mekhahlelo e meraro: potoloho, maske ea solder le li-inks tsa silkscreen.

2-1. Enke ea potoloho e sebelisoa e le thibelo ea ho thibela ho bola ha potoloho. E sireletsa mohala nakong ea etching. Ka kakaretso ke mokelikeli photosensitive; Ho na le mefuta e ‘meli: ho hanyetsa kutu ea acid le ho hanyetsa ho bola ha alkali.
2- 2. Solder resist inki e pentiloe ho potoloho ka mor’a hore potoloho e phethoe e le mohala o sireletsang. Ho na le mefuta ea li-photosensitive, e phekolang mocheso le mefuta e thatafatsang ea UV. The bonding pad e boloketsoe ka boto ho bebofatsa welding ea likarolo le ho phetha karolo ea ho insulation le ho thibela oxidation.
2-3. Enke ea silika e sebelisoa ho tšoaea bokaholimo ba boto, joalo ka letšoao la likarolo, hangata le tšoeu.

Ho feta moo, ho na le li-inks tse ling, joalo ka enke ea sekhomaretsi e hlobolang, enke ea peista ea silevera, jj.
