Zaj duab xis substrate Zaj duab xis substrate yog cov txheej txheem ntawm PCB Ntau lawm. Hauv kev tsim khoom ntawm qee yam PCB, txhua cov duab hluav taws xob (cov teeb liab txheej hauv Circuit Court graphics thiab hauv av, cov duab hluav taws xob hluav taws xob) thiab cov duab tsis zoo (welding resistance graphics thiab cim) yuav tsum muaj tsawg kawg yog ib zaj duab xis puag phaj. Daim ntawv thov ntawm zaj duab xis substrate nyob rau hauv PCB ntau lawm yog photosensitive daim npog qhov ncauj graphics nyob rau hauv graphic hloov lwm lub tsev, nrog rau circuit graphics thiab photoresistive graphics. Screen luam ntawv txheej txheem nyob rau hauv zus tau tej cov txhob lo lo ntxhuav, nrog rau thaiv welding graphics thiab cim; Machining (drilling thiab contour milling) CNC tshuab programming hauv paus thiab drilling siv.

Copper Clad Laminaters (CLL), hu ua Copper Clad foil layers los yog copper-clad plates, yog cov khoom siv substrate rau kev ua PCBS. Tam sim no, feem ntau siv etching PCBS yog xaiv etched ntawm tooj liab-clad ntawv ci kom tau cov kab xav tau thiab cov duab.

Tom qab kev tsim PCB tiav lawm, vim hais tias cov PCB pawg thawj coj saib me me dhau los ua kom tau raws li cov txheej txheem tsim khoom, lossis cov khoom tsim los ntawm ntau lub PCBS, nws yog ib qho tsim nyog los sib sau ua ke ob peb lub rooj tsavxwm me rau hauv lub rooj tsavxwm loj uas ua tau raws li qhov yuav tsum tau ua. Daim ntawv qhia zaj duab xis hauv paus yuav tsum tau ua ua ntej, thiab tom qab ntawd yuav tsum tau yees duab lossis rov tsim dua siv daim duab qhia chaw. Nrog rau kev tsim kho tshuab computer, luam board CAD thev naus laus zis tau ua tiav zoo, thiab PCB cov cuab yeej tsim khoom tau raug txhim kho sai heev rau ntau txheej, nyias hlau, qhov me me thiab cov kev taw qhia siab. Cov txheej txheem tsim zaj duab xis thawj zaug tsis tuaj yeem ua tau raws li kev xav tau ntawm PCB, yog li lub teeb duab tshuab tau tshwm sim. PCB graphics cov ntaub ntawv tsim los ntawm CAD tuaj yeem xa ncaj qha mus rau hauv lub computer system ntawm lub tshuab kos duab kho qhov muag siv lub teeb kos duab ncaj qha rau qhov tsis zoo, thiab tom qab ntawd tom qab kev txhim kho, kho cov yeeb yaj kiab version.

Lub cim ntawm cov ntaub ntawv teeb duab yog hloov cov ntaub ntawv tsim los ntawm CAD software rau hauv cov ntaub ntawv teeb duab (feem ntau Gerber cov ntaub ntawv), uas yog hloov kho thiab kho los ntawm CAM system kom ua tiav lub teeb duab ua ntej (collage, mirroring, thiab lwm yam), yog li ntawd. kom ua tau raws li qhov yuav tsum tau ua ntawm PCB cov txheej txheem tsim khoom, thiab tom qab ntawd xa cov ntaub ntawv ua tiav rau hauv lub teeb duab tshuab. Cov duab cov ntaub ntawv processor ntawm lub tshuab kho qhov muag painting yog hloov dua siab tshiab rau hauv raster cov ntaub ntawv, thiab cov ntaub ntawv raster raug xa mus rau lub laser optical painting tshuab los ntawm high magnifying ceev compression thiab kho algorithm kom tiav cov optical painting.
