6. O a vaega taua e lua o le apamemea foil e tusa ai ma metotia eseese o sauniuniga? O le a le mea e valaʻauina ai i IPC tulaga faʻatulagaina? E mafai ona vaevaeina i calendered apamemea foil ma electrolytic apamemea foil. Ua taʻua i latou o le vasega W ma le vasega E i tulaga faatonuina o le IPC

7. Faʻamatala puʻupuʻu le faʻatinoga o faʻatinoga ma sauniuniga metotia ole kalone apamemea kalena ma le uʻamea uʻamea eletise. O le pepa apamemea kalena faʻapitoa e faia e le tele o taimi e faʻaseʻe ai ipu apamemea. E pei o le uila eletise, e manaʻomia le faʻamalosi togafitiga pe a maeʻa le gaosia o fulufulu mamoe. O le punou tetee ma fetuutuunai coefficient o calendered apamemea foil e maualuga atu nai lo le electrolytic apamemea foil, o le mama apamemea e maualuga atu nai lo le electrolytic apamemea foil, ma le talatala luga e sili atu le molemole nai lo le electrolytic apamemea foil.

8. Faʻamatala puʻupuʻu eseese o mea taua o le eletise apamemea uʻamea ma lona aʻafiaga i mea totino o ‘apa faʻaʻofu laminate? A. Mafiafia. > B. Foliga Vaaia. C. Tensile malosi ma le faʻaumiumi. O le maualalo elongation ma vevesi malosi i le maualuga vevela o le a taitai atu ai i le suiga o dimensional tulaga mautu ma mafolafola o semi-avetaʻavale, le paʻu o le lelei o metallized pu i PCB ma le gau o apamemea foil pe a faʻaaogaina PCB. D. Paʻu malosi. O le malosi o le paʻu o le LP, VLP ma SLP apamemea foga ma maualalo Coarseness luga lolomi laupapa ma multilayer laupapa ma laina lelei e sili atu nai lo le masani ai apamemea foil (STD ma HTZ). E. Tetee gaugau. O le umi umi ma faʻasolosolo eseʻesega o le eletise eletise apamemea e fai si maualuga maualuga i le auala faʻasolosolo nai lo le itu faʻatatau. F. Papa talatala. G. Etchability. > H. Sili tetee vevela oxidation tetee. I se faʻaopopoga i luga atu o le valu taua autu faʻatauaina meatotino o apamemea foil, o loʻo i ai plasticity o apamemea foil, pipiʻi o UV vaitusi, lelei o apamemea foil, eletise coefficient ma lanu o apamemea foil.

9. Faʻamatala puʻupuʻu mai le faʻatinoina o le ie alava tioata? O mea masani e faʻatino ai mea taua e aofia ai: maʻafega ma ituaiga lalaga, lalaga tele (numera o lulu ma le lalata vulu), mafiafia, mamafa i le iunite vaega, lautele ma gagau malosi (malosi malosi).

10. E tusa ai ma le NEMA tulaga masani, e masani lava o pepa-faʻavae laminate-faʻaofuina laminate e vaevaeina e tusa ma a latou gaioiga. O a mea masani? O ituaiga taatele e aofia ai: XPC, xxxpc, FR-1 (xpc-fr), FR-2 (xxxpc-fr), fr-3, ma isi.

11. Faʻatusatusa lautele pepa-faʻavae apamemea-faʻaofuina laminate ma epoxy tioata ie faʻavae apamemea-ofu laminate? O se oloa e faia i le laupapa pulp pepa poʻo tioata alava ie e pei o le faʻamalosia, faʻamalosia ma resin, ufiufi i apamemea pepa i luga o le tasi poʻo le lua itu ma vevela oomi.
