Flexible Printed Circuit board (Flexible Printed Circuit Circuit Court hu ua FPC), tseem hu ua flexible circuit board, flexible circuit board, yog ib qho kev txhim khu kev qha, zoo heev saj zawg zog luam Circuit Court board ua los ntawm polyimide los yog polyester zaj duab xis raws li lub substrate. Nws muaj cov yam ntxwv ntawm kev xaim siab ceev, lub teeb yuag, nyias thickness thiab zoo dabtsi yog khoov.
FPC cov ntsiab lus xaiv cov khoom:
1. Cov khoom xaiv ntawm cov yuam sij sab / cov yuam sij
Sab tseem ceeb xaiv 18/12.5 ob sab electrolytic tooj liab (tshwj tsis yog tshwj xeeb), lub ntsiab tseem ceeb xaiv 18/12.5 ob sab electrolytic tooj liab (tshwj tsis yog tshwj xeeb). Lub sab tseem ceeb thiab tus yuam sij tseem ceeb tsis muaj qhov tshwj xeeb hauv kev khoov, thiab yog soldered thiab tsau rau ntawm lub rooj tsavxwm loj, tab sis yuav tsum xyuas kom meej tias tsis muaj qhov txawv txav hauv kev khoov rov qab ntau dua 8 zaug. Lub thickness ntawm tus yuam sij muaj cov kev cai nruj dua, txwv tsis pub nws yuav cuam tshuam qhov kev xav ntawm tus yuam sij, yog li nws yuav tsum ua kom tau raws li tag nrho cov thickness ntawm cov neeg siv khoom.
2.Txoj kev xaiv ntawm kev sib txuas cov hlau
Cov hlau txuas yog 18/12.5 ob-sided electrolytic tooj liab (tshwj tsis yog cov tshwj xeeb). Lub luag haujlwm tseem ceeb yog ua lub luag haujlwm sib txuas, thiab tsis muaj qhov tshwj xeeb uas yuav tsum tau khoov. Ob qhov kawg tuaj yeem welded thiab ruaj, tab sis nws yuav tsum tau lees paub tias tsis muaj qhov txawv txav ua ntej khoov rov qab thiab rov qab ntau dua 8 zaug.
3.Kev xaiv cov khoom siv pabcuam
Thaum xaiv daim ntawv nplaum, lub rooj tsav xwm zoo tib yam tsis xav tau SMT tuaj yeem siv cov ntawv nplaum uas muaj qhov kub thiab txias (xws li cov ntawv tseem ceeb ntawm sab), thiab qhov xav tau ntawm SMT yuav tsum siv cov ntawv nplaum uas muaj qhov kub thiab txias (xws li SMT los ntawm cov ntawv tseem ceeb).
4.Kev xaiv cov khoom siv hluav taws xob
Thaum xaiv daim ntawv conductive, zoo tib yam conductive nplaum yog haum rau cov uas tsis tshua muaj hluav taws xob conductivity yuav tsum tau (xws li zoo tib yam keyplate), thiab zoo conductive khoom yog haum rau cov uas muaj hluav taws xob conductivity yuav tsum tau thiab yuav tsum tau siv daim ntawv nplaum (xws li tshwj xeeb keyplate, thiab lwm yam. ), tab sis daim ntawv nplaum no feem ntau tsis pom zoo vim tias tus nqi siab dhau lawm.
Cov khoom siv hluav taws xob ntawm cov ntaub siv hluav taws xob tuaj yeem ua tau, tab sis cov viscosity tsis zoo tagnrho, thiab nws feem ntau haum rau cov chav kawm keyplate.
Conductive pure adhesive yog cov khoom siv hluav taws xob muaj zog, feem ntau yog siv los txuas cov ntawv hlau, tab sis nws tsis pom zoo kom siv cov nplaum nplaum nplaum, vim tias tus nqi siab dhau lawm.
5.Cov khoom xaiv ntawm zawv zawg npog phaj
Ob txheej txheej zawv zawg npog phaj yog 1/30Z ib leeg-txheej uas tsis yog-gel electrolytic tooj liab, uas yog mos thiab du. Ob chav sided zawv zawg npog phaj yog 1/30Z ob-sided non-adhesive electrolytic tooj liab, uas yog mos thiab du. Lub neej ntawm zawv zawg npog phaj ua los ntawm 1/30Z ob-sided tooj liab-dawb electrolytic tooj liab zoo dua li ntawm 1/30Z ib leeg-sab tooj liab-dawb electrolytic tooj liab. Nyob rau hauv rooj plaub uas tsis muaj teeb meem nrog cov qauv, nws raug nquahu kom tsim FPC ua ob sab zawv zawg npog phaj kom deb li deb tau. Nyob rau hauv cov nqe lus ntawm tus nqi, kev siv 1/30Z ob-sided tooj liab-dawb electrolytic tooj liab nce tus nqi li ntawm 30% piv nrog rau kev siv 1/30Z ib leeg-sided tooj liab-dawb electrolytic tooj liab cov khoom tseem ceeb, tab sis kev siv ntawm no cov khoom siv yuav txhim kho cov khoom tsim tawm, thiab kev sim lub neej kuj tuaj yeem txhim kho, uas tuaj yeem ua kom ruaj khov ntawm hom phaj no.
6.Kev xaiv ntawm ntau txheej txheej board
Multilayer phaj yog 1/30Z uas tsis yog-colloidal electrolytic tooj liab, uas yog mos thiab ductile. Nyob rau hauv rooj plaub uas tsis muaj teeb meem ntawm cov qauv, kev tsim cov flap tuaj yeem raug kuaj.
