Cov khoom thiab xaiv cov txheej txheem ntawm cov khoom siv hluav taws xob hloov pauv tau yooj yim

(1) FPC av tuaj

Polyimide feem ntau siv los ua cov khoom siv hloov pauv tau ntawm lub rooj tsavxwm, uas yog qhov kub thiab tiv taus cov khoom siv polymer siab. Nws yog cov khoom siv polymer tsim los ntawm DuPont. Polyimide tsim los ntawm DuPont hu ua Kapton. Ib qho ntxiv, koj kuj tseem tuaj yeem yuav qee cov polyimides uas ua hauv Nyij Pooj, uas pheej yig dua DuPont.

Nws tuaj yeem tiv taus qhov kub txog 400 ℃ rau 10 vib nas this thiab muaj lub zog tensile ntawm 15000-30000 psi.

nees nkaum tsib μ M tuab FPC substrate yog qhov pheej yig tshaj thiab siv dav tshaj plaws. Yog tias lub rooj sib tham hloov pauv tau xav tau nyuaj dua, 50 yuav tsum raug xaiv μ M cov khoom siv hauv paus. Ntawm qhov tsis sib xws, yog tias lub rooj tsav xwm hloov pauv hloov tau yuav tsum tau softer, xaiv 13 μ M cov khoom siv hauv paus.

(2) Pob tshab nplaum rau FPC substrate

Nws tau muab faib ua epoxy resin thiab polyethylene, ob qho tib si yog thermosetting adhesives. Lub zog ntawm polyethylene yog qhov tsawg. Yog tias koj xav kom lub rooj tsav xwm hluav taws xob ua kom mos, xaiv polyethylene.

Lub thicker substrate thiab cov pob tshab nplaum rau nws, nyuaj rau lub rooj tsav xwm hauv Circuit Court. Yog tias lub rooj tsav xwm hauv cheeb tsam muaj thaj tsam khoov loj, yuav tsum tau xaiv ib txheej tuab thiab cov pob tshab kom deb li sai tau kom txo tau qhov kev nyuab siab ntawm cov nplaim tooj liab, kom lub sijhawm ntawm cov kab nrib pleb hauv cov ntawv ci tooj liab yog me me. Tau kawg, rau cov cheeb tsam zoo li no, cov laug cam ib txheej yuav tsum raug xaiv kom deb li deb tau.

(3) FPC tooj liab ntawv ci

Nws tau muab faib ua tooj liab thiab tooj liab electrolytic. Calendered tooj liab muaj lub zog siab thiab khoov tsis kam, tab sis tus nqi yog kim. Electrolytic tooj liab yog pheej yig dua, tab sis nws muaj lub zog tsis zoo thiab yooj yim tawg. Nws yog feem ntau siv nyob rau qee lub sijhawm nrog ob peb khoov.

Lub tuab ntawm cov ntawv ci tooj liab yuav tsum raug xaiv raws li qhov dav dav thiab qhov tsawg kawg ntawm qhov nrug ntawm cov hlau lead. Cov ntawv ci tooj liab ua nyias nyias, qhov me me qhov dav tsawg kawg thiab qhov sib nrug uas tuaj yeem ua tiav.

Thaum xaiv tooj liab tooj liab, ua tib zoo saib xyuas cov txheej txheem ntawm cov ntawv ci tooj liab. Cov txheej txheem calendering ntawm cov ntawv ci tooj liab yuav tsum zoo ib yam nrog txoj kev khoov tseem ceeb ntawm lub rooj tsav xwm hauv Circuit Court.

(4) Cov yeeb yaj kiab tiv thaiv thiab cov nplaum nplaum ntawm nws

Ib yam li ntawd, 25 μ M cov yeeb yaj kiab tiv thaiv yuav ua rau lub rooj sib tham hloov pauv nyuaj dua, tab sis tus nqi pheej yig dua. Rau lub rooj tsav xwm hauv Circuit nrog khoov loj, nws yog qhov zoo tshaj los xaiv 13 μ M zaj duab xis tiv thaiv.

Pob tshab nplaum tseem tau muab faib ua epoxy cob thiab polyethylene. Lub rooj tsav xwm hauv Circuit Court siv epoxy cob yog qhov nyuaj. Tom qab kub nias, qee qhov nplaum nplaum yuav raug nthuav tawm los ntawm ntug ntawm cov yeeb yaj kiab tiv thaiv. Yog tias lub ncoo loj dua qhov qhib qhov loj ntawm cov yeeb yaj kiab tiv thaiv, cov nplaum txuas ntxiv yuav txo qhov ncoo loj thiab ua rau cov npoo tsis xwm yeem. Lub sijhawm no, 13 yuav tsum tau xaiv kom deb li deb tau μ M tuab pob tshab nplaum.

(5) Txheej txheej

Rau lub rooj tsav xwm hauv Circuit nrog khoov loj thiab ib feem ntawm lub ncoo nthuav tawm, cov xaim hluav taws xob nickel + cov xim tsis muaj xim kub plating txheej yuav tsum tau saws, thiab txheej npib tsib xee yuav tsum ua kom tuab li sai tau: 0.5-2 μ m. Tshuaj kub txheej 0.05-0.1 μ m。
