Mokhoa oa tlhahiso

Kenyelletso ea Mehato ea Ts'ebetso:

1. Litaba Tse Bulang

Khaola thepa e tala koporo clad laminate ho ea boholo bo hlokehang bakeng sa tlhahiso le tshebetso.

Thepa ea mantlha:sekoahelo sa thepa.

2. Ho Etsa Graphics Of The Inner Layer

The photosensitive anti-corrosion filimi e koahetsoe ka holim'a koporo clad laminate, 'me anti-etching tšireletso paterone thehoa holim'a koporo clad laminate ka ho pepesehela mochine,' me joale mokhanni oa potoloho paterone e thehoa ka ho ntshetsa pele le etching. ka holim'a seaparo sa koporo sa laminate.

Thepa ea mantlha:koporo poleiti holim 'a ho hloekisa rapameng mola, filimi ho peista mochini, ho pepesehela mochine, tshekaletseng etching mola.

3. Inner Layer Pattern Pattern

The automatic optical scanning ea conductor circuit pattern on the copper clad laminate e bapisoa le data original design ho hlahloba hore na ho na le mefokolo e kang e bulehileng / e khutšoanyane ea potoloho, notch, koporo e setseng joalo-joalo.

Thepa ea mantlha:mochine oa mahlo.

4. Browning

Filimi ea oxide e thehoa holim'a sebopeho sa mohala oa mokhanni, 'me sebopeho sa khekhe ea linotsi se sa bonahaleng se thehoa holim'a sebopeho se boreleli sa mokhanni, se eketsang ho hlaka ha sebopeho sa mokhanni, ka hona ho eketsa sebaka sa ho ikopanya pakeng tsa mohlala oa conductor le resin. , ho matlafatsa matla a maqhama pakeng tsa resin le mohlala oa conductor, ebe o matlafatsa botšepehi ba ho futhumatsa ha multilayer PCB.

Thepa ea mantlha:tshekaletseng sootho mola.

5. Ho hatella

The foil koporo, lakane seka-solidified le boto konokono (koporo clad laminate) ea paterone e entsoeng superimposed ka tatellano e itseng, 'me joale bonded ka kakaretso tlas'a boemo ba mocheso le phahameng khatello ea ho theha multilayer laminate.

Thepa ea mantlha:vacuum press.

6.Ho phunya

Lisebelisoa tsa ho cheka tsa NC li sebelisetsoa ho phunya masoba holim'a boto ea PCB ka ho itšeha ka mochini ho fana ka likanale tsa mela e hokahantsoeng lipakeng tsa mekhahlelo e fapaneng kapa masoba a ho beha lits'ebetso tse latelang.

Thepa ea mantlha:Mochine oa ho cheka oa CNC.

7 .Koporo e Tebang

Ka mokhoa oa autocatalytic redox reaction, lera la koporo le ile la beoa holim'a resin le fiber ea khalase leboteng la lesoba kapa lesoba le foufetseng la boto ea PCB, e le hore lerako la pore le be le conductivity ea motlakase.

Thepa ea mantlha:terata ya koporo e tshekaletseng kapa e emeng.

8.PCB Plating

Boto eohle e electroplated ke mokhoa oa electroplating, e le hore botenya ba koporo ka sekoting le holim'a boto ea potoloho e ka finyella litlhoko tsa botenya bo itseng, 'me conductivity ea motlakase pakeng tsa likarolo tse fapaneng tsa boto ea multilayer e ka phethahala.

Thepa ea mantlha:pulse plating line, terata e otlolohileng e tsoelang pele.

9. Tlhahiso ea Graphics ea Outer Layer

A photosensitive anti-corrosion filimi e koahetsoeng ka holim'a PCB, 'me mokhoa oa tšireletso o khahlanong le etching o thehoa holim'a PCB ka mochine oa ho pepeseha, ebe joale ho thehoa mokhoa oa potoloho oa conductor holim'a laminate ea koporo. ka ntshetsopele le etching.

Thepa ea mantlha:PCB boto ea ho hloekisa mohala, mochini o pepesehang, mohala oa nts'etsopele, mohala oa etching.

10. Ho Khetholla Moetso oa Kantle oa Layer

The automatic optical scanning ea conductor circuit pattern on the copper clad laminate e bapisoa le data original design ho hlahloba hore na ho na le mefokolo e kang e bulehileng / e khutšoanyane ea potoloho, notch, koporo e setseng joalo-joalo.
