Njira yopanga

Chidziwitso cha Njirayi:

1. Nkhani Yotsegulira

Dulani zopangira zamkuwa zovekedwa ndi laminate kukula kofunikira kupanga ndi kukonza.

Zida zazikulu:chotsegulira zinthu.

2. Kupanga Zojambula Zamkati Zamkati

The photosensitive odana ndi dzimbiri filimu yokutidwa pamwamba pa mkuwa atavala laminate, ndi odana etching chitetezo chitsanzo aumbike pamwamba pa mkuwa atavala laminate ndi kukhudzana makina, ndiyeno kondakitala dera chitsanzo aumbike mwa kupanga ndi etching. pamwamba pa mkuwa atavala laminate.

Zida zazikulu:mkuwa mbale pamwamba kuyeretsa yopingasa mzere, filimu kumata makina, kukhudzana makina, yopingasa etching mzere.

3. Kuzindikira Kwachitsanzo Chamkati Chamkati

The basi kuwala kuwala sikani ya kondakitala dera chitsanzo pamwamba pa mkuwa clad laminate poyerekeza ndi deta choyambirira kapangidwe kuona ngati pali zolakwika monga lotseguka / yochepa dera, mphako, mkuwa otsalira ndi zina zotero.

Zida zazikulu:Optical scanner.

4. Browning

An okusayidi filimu aumbike pamwamba pa kondakitala mzere chitsanzo, ndi yaying'ono zisa dongosolo aumbike pa yosalala kondakitala chitsanzo pamwamba, amene kumawonjezera roughness pamwamba pa kondakitala chitsanzo, potero kuonjezera kukhudzana malo pakati pa kondakitala chitsanzo ndi utomoni. , kukulitsa mphamvu yomangirira pakati pa utomoni ndi kondakitala, ndiyeno kukulitsa kudalirika kwa kutentha kwa multilayer PCB.

Zida zazikulu:chopingasa browning mzere.

5. Kukanikiza

The zojambulazo mkuwa, ndi theka-olimba pepala ndi pachimake bolodi (mkuwa atavala laminate) wa anapanga chitsanzo ndi superimposed mu dongosolo linalake, ndiyeno amamangiriridwa mu lonse pansi pa chikhalidwe cha kutentha ndi kuthamanga kwambiri kupanga multilayer laminate.

Zida zazikulu:vacuum press.

6.Kubowola

Zipangizo zobowola za NC zimagwiritsidwa ntchito kubowola mabowo pa bolodi la PCB podula makina kuti apereke njira zolumikizirana pakati pa zigawo zosiyanasiyana kapena mabowo oyika pazotsatira.

Zida zazikulu:CNC pobowola cholumikizira.

7 .Mkuwa Womira

Pogwiritsa ntchito autocatalytic redox reaction, mkuwa udayikidwa pamwamba pa utomoni ndi ulusi wagalasi pamabowo kapena khoma lakhungu la bolodi la PCB, kuti khoma la pore likhale ndi mphamvu zamagetsi.

Zida zazikulu:waya wamkuwa wopingasa kapena woyima.

8.PCB Plating

bolodi lonse ndi electroplated ndi njira electroplating, kuti makulidwe amkuwa mu dzenje ndi pamwamba pa bolodi dera akhoza kukwaniritsa zofunika za makulidwe ena, ndi madutsidwe magetsi pakati pa zigawo zosiyanasiyana za bolodi multilayer akhoza anazindikira.

Zida zazikulu:kugunda plating mzere, ofukula mosalekeza plating mzere.

9. Kupanga Zithunzi Zosanjikiza Zakunja

A photosensitive odana ndi dzimbiri filimu yokutidwa pamwamba pa PCB, ndi odana etching chitetezo chitsanzo aumbike pamwamba pa PCB ndi kukhudzana makina, ndiyeno kondakitala dera chitsanzo aumbike pamwamba pa mkuwa clad laminate. pa chitukuko ndi etching.

Zida zazikulu:PCB board kuyeretsa mzere, makina kukhudzana, mzere chitukuko, etching mzere.

10. Kuzindikiritsa Zitsanzo za Zigawo Zakunja

The basi kuwala kuwala sikani ya kondakitala dera chitsanzo pamwamba pa mkuwa clad laminate poyerekeza ndi deta choyambirira kapangidwe kuona ngati pali zolakwika monga lotseguka / yochepa dera, mphako, mkuwa otsalira ndi zina zotero.

Zida zazikulu:Optical scanner.

11. Kukaniza kuwotcherera

The madzi photoresist flux ntchito kupanga solder kukana wosanjikiza pamwamba pa bolodi PCB mwa ndondomeko kukhudzana ndi chitukuko, kuti kupewa PCB bolodi kukhala yochepa-circuited pamene zigawo kuwotcherera.

Zida zazikulu:makina osindikizira pazenera, makina owonetsera, mzere wa chitukuko.

12. Chithandizo cha Pamwamba

A wosanjikiza zoteteza aumbike pamwamba pa kondakitala dera chitsanzo cha bolodi PCB kuteteza makutidwe ndi okosijeni wa kondakitala mkuwa kusintha nthawi yaitali kudalirika kwa PCB.

Zida zazikulu:Shen Jin Line, Shen Tin Line, Shen Yin Line, etc.

13.PCB Nthano Yosindikizidwa

Sindikizani chilemba pa malo omwe atchulidwa pa bolodi la PCB, lomwe limagwiritsidwa ntchito kuzindikira ma code osiyanasiyana, ma tag amakasitomala, ma tag a UL, ma cycle marks, ndi zina zambiri.

Zida zazikulu:Makina osindikizira a nthano ya PCB

14. Kugaya Mawonekedwe

Mphepete mwa chida cha bolodi cha PCB ndi mphero ndi makina opangira mphero kuti apeze gawo la PCB lomwe limakwaniritsa zofunikira za kasitomala.
