Ata tifaga substrate Ata tifaga substrate o le taʻiala gaioiga o PCB Gaosiga. I le gaosiga o se ituaiga o PCB, taʻitasi eletise ata (faʻailoga vaega matagaluega ata ma le eleele, mana vaega ata) ma le le conductive ata (uʻamea teteʻe ata ma mataitusi) tatau ona le itiiti ifo ma le tasi ata ata ipu ipu. O le faʻaogaina o mea faʻapipiʻi ata i le gaosiga o le PCB o faʻataʻitaʻiga matapulepule photosensitive i le faʻaliliuina o kalafi, e aofia ai faʻataʻitaʻiga faʻataʻitaʻi ma ata faʻataʻitaʻi. Faʻasologa o masini lolomiina i le gaosiaina o silika, e aofia ai le polokaina o uelo ata ma mataitusi; Masini (viliina ma faʻafanua milling) CNC masini faʻavae faʻavae faʻavae ma viliina faʻasino.

Copper Clad Laminaters (CLL), e taʻua o le Copper Clad foil layer poʻo le plate-clad, o mea taua ia mo le faia o le PCBS. I le taimi nei, o le sili ona lautele faʻaaogaina etching PCBS o loʻo filifilia togitogia i luga o apamemea-ofu pepa e maua ai le manaʻomia laina ma ata.

A maeʻa le mamanu PCB, ona e laʻititi tele le foliga o le laupapa PCB e faʻafetaui ai le gaosiga o manaʻoga, poʻo se oloa e aofia ai le tele o PCBS, e tatau ona faʻapipiʻi ni nai laupapa laiti i totonu o se laupapa tele e fetaui ma manaʻoga gaosiga. O le ata faʻavae faʻavae e tatau ona muamua faia, ona puʻeina lea o ata pe toe gaosia e faʻaaoga ai le faʻafanua autu. Faʻatasi ai ma le atinaʻeina o tekonolosi komepiuta, lolomi laupapa CAD tekinolosi ua faia le alualu i luma tele, ma PCB gaosiga tekinolosi ua vave ona faaleleia i le tele-layer, uaea manifinifi, pu laiti ma le itu maualuga-density. O le muamua gaosiga ata tifaga gaioiga mafai ona toe faʻamalieina le mamanu manaʻoga o PCB, ina malamalama malamalama tekinolosi ua oso mai. PCB ata faila o faamatalaga fuafuaina e le CAD e mafai ona auina saʻo i le faiga komepiuta o le masini ata tusi opitika e faaaoga ai le malamalama e tusi saʻo ata i luga o le leaga, ma ina ua uma atinae, lomiga tumau ata tifaga.

Le gaosiga o malamalama malamalama faʻamatalaga e tatau ona suia le mamanu faʻamatalaga fausiaina e le CAD polokalama i malamalama malamalama ata (tele Gerber faʻamaumauga), lea e fesuiaʻi ma faʻatonutonuina e le CAM faiga e faʻatumu malamalama malamalama preprocessing (ata, faʻata, ma isi), ina ia e faʻamalieina ai manaʻoga o PCB gaosiga gaioiga, ona lafo lea o faʻagasologa o faʻamatalaga i le malamalama ata masini. O le ata faʻamaumauga gaosi o le opitika atavali masini suia i raster faʻamatalaga, ma le raster faʻamatalaga lafoina i le leisa opitika atavali masini e ala i le maualuga faʻateleina vave faʻamalosiʻau ma toefuatai algorithm e faʻamaeʻa le opitika atavali.
