Iyini i-Copper Clad Laminate futhi Yenziwa Kanjani?

I-laminate egqokwe ngethusi iwuhlobo lweshidi oluhlanganisiwe oluqukethe izingxenye ezintathu ezisebenzayo ezihlanganiswe ndawonye: ungqimba lokuqinisa (indwangu yengilazi noma iphepha elilukiwe ngokuvamile), i-resin matrix (i-epoxy, i-polyimide, i-PTFE, noma amanye ama-polymer), kanye ne-copper foil eboshwe kobuso obubodwa noma bobabili. Inhlanganisela inquma izakhiwo zikagesi, ezishisayo, kanye nezemishini ze-PCB substrate ephumayo.

Inqubo yokukhiqiza iqala ngokufaka: indwangu yokuqinisa idonswa ngebhavu le-resin, bese idluliswa kuhhavini wokomisa ukuze ikhiqize i-prepreg (izinto ezifakwe ngaphambi kokuzifaka) esimweni sesigaba se-B esipholile kancane. Amashidi amaningi okufaka ngaphambi kokuzifaka afakwa nge-foil yethusi ezindaweni zangaphandle futhi acindezelwe ngokucindezela kwe-hydraulic emazingeni okushisa ajwayelekile aphakathi kuka-170-200°C kanye nokucindezela okungu-300-500 PSI. Ukushisa kubangela ukuthi i-resin igeleze futhi iphole ngokuphelele (isigaba se-C), ibophe zonke izendlalelo eshidini eliqinile elinomshini. Ngemva kokucindezela, ishidi liyasikwa, lihlolwe ukuthi lilingana kangakanani ubukhulu, lihlolwe izakhiwo zikagesi, futhi lisikwe ngobukhulu bephaneli obujwayelekile - ngokuvamile okungu-1,020 × 1,220 mm noma okungu-1,020 × 915 mm.

I-foil yethusi ikhiqizwa ngokwehlukana nge-electrodeposition (i-foil ye-ED) noma i-rolling (i-foil ye-RA). I-foil yethusi ye-ED, ekhiqizwa nge-electroplating ithusi esigubhuni se-titanium esijikelezayo, iyindinganiso yokusetshenziswa kwe-PCB eqinile. I-foil yethusi ye-RA (egoqwe i-annealed) inobuso obubushelelezi kanye ne-ductility ephezulu, okwenza kube ukukhetha okufanele kwama-PCB aguquguqukayo lapho kudingeka khona ukugoba okuphindaphindiwe.

Amapharamitha Amane Anquma Ukusebenza kwe-CCL

I-Dielectric constant (Dk)

I-dielectric constant ichaza ukuthi into ethile inciphisa kangakanani ukusabalala kwegagasi le-electromagnetic uma kuqhathaniswa nesikhala esikhululekile. Ngokwe-PCB, i-Dk inquma ngqo ijubane lokusabalala kwesignali kanye ne-controlled-impedance trace geometry. Ijubane lokusabalala lilingana ne-1/√Dk — into ene-Dk = 4.0 isakaza amasignali ngesigamu sejubane lokukhanya, kuyilapho into ene-Dk = 2.2 isakaza ku-67% wejubane lokukhanya. Lokhu kubalulekile emiklamo ezwela isikhathi lapho ukubambezeleka kwesignali kumele kuhambisane nemigqa ehambisanayo.

I-Dk iphinde ithinte ububanzi bomkhondo wokuvimbela ukuvimba olawulwayo. Ku-microstrip engu-50Ω ku-FR-4 ejwayelekile (Dk ≈ 4.2), ububanzi bomkhondo webhodi elingu-1.6mm elinethusi elingu-1 oz cishe bungu-2.8mm. Ku-laminate ekhethekile yokulahlekelwa okuphansi (Dk = 3.38), umkhondo ofanayo udinga umkhondo omncane - i-Dk engezansi ishintsha i-geometry. Onjiniyela abachaza imikhondo yokuvimbela ukuvimba okulawulwayo kumele bazi inani langempela le-Dk le-laminate, hhayi nje izinga layo, ngoba i-Dk iyahlukahluka ngokuvama kanye nokushisa.

I-Dissipation factor (Df)

Isici sokuhlakazeka silinganisa ingxenye yamandla esignali alahlekayo njengokushisa njengoba esakazeka nge-dielectric. Ngemvamisa ephansi, i-Df inegalelo elincane ekulahlekelweni kwesignali. Ngaphezulu kwe-1 GHz, ukulahlekelwa kokufakwa okuhlobene ne-Df kuba yisithiyo esikhulu sokuklama. Ku-10 GHz, ibhodi ejwayelekile ye-FR-4 ene-Df ≈ 0.020 izobonisa cishe ukulahleka kwe-dielectric okungu-3–5 dB/10cm - okwanele ukonakalisa indlela yesignali ngaphezu kobude obuphakathi bokulandelela. i-laminate ekhethekile yokulahlekelwa okuphansi ene-Df = 0.0037 inciphisa lokhu kulahlekelwa cishe ngo-5×, yingakho imiklamo ye-PCB yemvamisa ephezulu idinga i-laminate ekhethekile.

Umphumela osebenzayo: uma umklamo wakho usebenzisa ukuxhumana, amawashi, noma izimpawu ze-RF ezingaphezu kuka-1-2 GHz, i-Df iba yindlela eyinhloko yokukhetha izinto.

Izinga lokushisa lengilazi (Tg)

I-Tg izinga lokushisa lapho i-resin ye-polymer ishintsha khona isuka esimweni esiqinile sengilazi iye esimweni esithambile serabha. Ngaphezulu kwe-Tg, i-CCL ilahlekelwa ukuzinza kobukhulu, i-CTE iyanda kakhulu, futhi ukusebenza okuqhubekayo kubangela ukuqhekeka kanye nokuqhekeka kwemigqomo yokushisa. Izinga lokushisa lokusebenza lebhodi elisebenzayo kumele lihlale liphansi kwe-Tg - ngokuvamile ngomkhawulo okungenani ongu-20–30°C.

I-FR-4 ejwayelekile ene-Tg 130–140°C yanele kuma-electronics abathengi anamazinga okushisa angaphansi kuka-85°C. Imishini yezimboni emakhabetheni ezimoto, ezindaweni zokuvala zangaphandle, kanye nezinhlelo zokusebenza ezingaphansi kwezimoto zidinga i-FR-4 ene-Tg ephezulu (Tg 150–170°C) noma i-polyimide (Tg > 250°C) ukuze ikwazi ukusinda emazingeni okushisa aphezulu aqhubekayo ngaphandle kokuwohloka kwe-substrate.

I-coefficient of thermal expansion (CTE)

I-CTE ichaza ukuthi izinto zikhula kangakanani ngokwenyuka kwezinga lokushisa ngeyunithi ngayinye. I-Z-axis CTE ye-FR-4 (ngobukhulu bebhodi) ngokuvamile ingama-50–70 ppm/°C — iphakeme kakhulu kune-17 ppm/°C CTE yethusi. Ngesikhathi sokujikeleza kokushisa, lokhu kungafani kudala ukucindezeleka komshini emgodini odlulayo ngamabhareli, ekugcineni kubangele ukuqhekeka kokukhathala ku-copper plating. Amabhodi anezibalo eziphezulu zezendlalelo (ithusi eliningi, ukucindezeleka kokushisa okukhulu) kanye namabhodi asetshenziswayo ngokujikeleza kokushisa okukhulu (izimoto, izimboni zangaphandle) adinga ama-laminate ane-Z-axis CTE ephansi, noma ngemiklamo evumela ukungafani. Ama-laminate akhethekile e-CTE aphansi anganciphisa i-Z-axis CTE ibe ngu-40 ppm/°C noma ngaphansi.
