Raws li tus naj npawb ntawm PCB txheej, nws tau muab faib ua ib sab, ob sab, thiab ntau txheej boards.Peb lub rooj tsavxwm txheej txheem tsis zoo ib yam.

Tsis muaj txheej txheem txheej txheej sab hauv rau ib sab thiab ob sab vaj huam sib luag, pib txiav-drilling-ua raws cov txheej txheem.
Multilayer boards yuav muaj cov txheej txheem sab hauv

1) Ib leeg vaj huam sib luag txheej txheem ntws
Txiav thiab edging → drilling → txheej txheej graphics → (tag nrho board kub plating) → etching → soj ntsuam → silk screen solder daim npog qhov ncauj → ( cua kub leveling) → silk screen cim → puab → kuaj → tshuaj xyuas

2) txheej txheem ntws ntawm ob sab tin spraying board
Txiav ntug sib tsoo → drilling → hnyav tooj liab thickening → txheej txheej duab → tin plating, etching tin tshem tawm → theem nrab drilling → tshuaj ntsuam → tshuaj ntsuam luam ntawv solder daim npog qhov ncauj → kub-plated plug → cua kub leveling → silk screen cim → puab ua → kuaj → xeem

3) txheej txheem ob-sided npib tsib xee-kub plating
Txiav ntug sib tsoo → drilling → hnyav tooj liab thickening → txheej txheej duab → npib tsib xee plating, kub tshem tawm thiab etching → theem nrab drilling → tshuaj xyuas → silk screen solder daim npog qhov ncauj → silk screen cim → puab ua → kuaj → tshuaj xyuas

4) txheej txheem ntws ntawm ntau txheej board tin spraying board
Txiav thiab sib tsoo → drilling positioning qhov → puab txheej graphics → puab txheej etching → soj ntsuam → blackening → lamination → drilling → hnyav tooj liab thickening → txheej txheej graphics → tin plating, etching tin tshem tawm → theem nrab drilling → tshuaj xyuas → Silk screen solder mask → Kub -plated plug → Cua kub leveling → Silk screen cim → Shape processing → Test → Inspection

5) txheej txheem ntws ntawm npib tsib xee-kub plating ntawm multilayer boards
Txiav thiab sib tsoo → drilling positioning qhov → puab txheej graphics → puab txheej etching → soj ntsuam → blackening → lamination → drilling → hnyav tooj liab thickening → txheej txheej graphics → kub plating, zaj duab xis tshem tawm thiab etching → theem nrab drilling → tshuaj xyuas → Screen printing solder daim npog qhov ncauj → tshuaj ntsuam luam ntawv cim → puab ua → kuaj → tshuaj xyuas

6) Cov txheej txheem ntws ntawm ntau txheej phaj immersion npib tsib xee-kub phaj
Txiav thiab sib tsoo → drilling positioning qhov → puab txheej graphics → puab txheej etching → soj ntsuam → blackening → lamination → drilling → hnyav tooj liab thickening → txheej txheej graphics → tin plating, etching tin tshem tawm → theem nrab drilling → tshuaj xyuas → Silk screen solder mask → Tshuaj Immersion Nickel Kub → Silk screen cim → Cov duab ua haujlwm → Test → Inspection.
