Thaum cov pab pawg engineering nug peb txog FPC kev ruaj ntseg zoo, qhov kev xav tsis zoo tshaj plaws yog qhov kev soj ntsuam pom tau txaus. Nws tsis yog. IPC/JPCA-6202 tus qauv thiab nws cov txheej txheem kev xeem cuam tshuam hauv IPC-TM-650 txhais cov lus meej rau kev txheeb xyuas seb lub voj voog luam ntawv hloov pauv tau raws li qhov yuav tsum tau ua rau hauv chav kawm ntawv thov. Kev nkag siab txog qhov kev ntsuam xyuas tseem ceeb rau koj cov ntaub ntawv siv tshwj xeeb pab koj muaj kev sib tham zoo dua nrog koj cov chaw tsim khoom thiab txo qhov kev pheej hmoo ntawm kev tsim nyog xav tsis thoob.
Ntawm CSNT-EMS hauv Dongguan, peb khiav IPC-TM-650 qhov kev xeem ntawm ib-ntau rau Class 2 thiab Class 3 FPC ntau lawm. Kab lus no taug kev los ntawm cov kev ntsuam xyuas uas muaj feem cuam tshuam seb koj lub flex circuit dhau los yog ua tsis tiav.
Peel Strength Testing: IPC-TM-650 Txoj Kev 2.4.9
Peel lub zog ntsuas lub zog yuav tsum tau tshem tawm cov kab tooj liab los ntawm qhov hloov pauv tau yooj yim. Qhov kev ntsuam xyuas yog khiav ntawm 90-degree lossis 180-degree lub kaum sab xis nyob ntawm cov qauv geometry, thiab cov txiaj ntsig tau qhia hauv Newtons ib millimeter (N / mm).
IPC/JPCA-6202 Chav Kawm 2 yuav tsum muaj yam tsawg kawg nkaus tus neeg xyuas pib tev lub zog ntawm 0.49 N / mm. Chav kawm 3 siv tib yam tsawg kawg nkaus. Qhov sib txawv ntawm Chav Kawm 2 thiab Chav Kawm 3 yog nyob ntawm qhov piv txwv zaus, tsis yog nyob ntawm tus nqi pib thiab qhov kev lees txais rau ntau qhov kev tso tawm.
Panasonic R-F777 cov khoom siv feem ntau qhia txog 0.525 N/mm, uas muab cov paj tau paj saum toj kawg nkaus IPC/JPCA-6202 yam tsawg kawg nkaus. Thaum soj ntsuam cov ntaub ntawv cov ntaub ntawv, paub meej tias cov ntaub ntawv tev tawm lub zog yog ntsuas ib IPC-TM-650 Txoj Kev 2.4.9 thiab tsis yog los ntawm txoj kev yooj yim uas yuav ua rau cov txiaj ntsig tsis sib piv.
Rau coverlay tev lub zog, IPC / JPCA-6202 yam tsawg kawg nkaus yog 0.34 N / mm. Coverlay adhesion tsis ua hauj lwm feem ntau taug qab rov qab mus rau kev sib kis ntawm lub substrate nto ua ntej lamination los yog tsis raug lamination kub thiab siab profiles.
Dielectric Strength Testing: IPC-TM-650 Txoj Kev 2.5.6
Dielectric lub zog kuaj xyuas tias qhov hloov pauv tau yooj yim tuaj yeem tiv taus qhov siv hluav taws xob tsis muaj qhov tawg. Qhov kev ntsuam xyuas siv AC voltage ntawm ob lub electrodes embedded nyob rau hauv cov khoom siv dielectric thiab ntsuas qhov voltage ntawm qhov tsis ua hauj lwm tshwm sim.
Rau FPC siv hauv cov khoom siv hluav taws xob, qhov ntsuas hluav taws xob feem ntau yog 500 VAC ib IPC / JPCA-6202. Rau kev kho mob thiab aerospace daim ntawv thov, qhov ntsuas hluav taws xob yuav siab dua nyob ntawm cov khoom tshwj xeeb kev nyab xeeb uas siv.
Dielectric lub zog tsis ua haujlwm feem ntau qhia tias muaj kab mob hauv cov txheej txheem dielectric, voids hauv cov khoom siv substrate, lossis delamination ntawm txheej. Kev kuaj tsis ua tiav ntawm lub zog dielectric ntawm ntau lawm yog qhov tsis tshua muaj tshwm sim thaum kev tshuaj xyuas cov khoom nkag tau ua tiav.
Rwb thaiv tsev Resistance: IPC-TM-650 Method 2.6.3
Rwb thaiv tsev kuj ntsuas qhov tsis kam ntawm cov conductors cais. Tom qab cov txheej txheem ya raws ua ntej (85 degrees Celsius, 85 feem pua ntawm cov av noo rau 96 teev), qhov tsawg kawg nkaus rwb thaiv tsev rau FPC yog 100 megohms (10^8 ohms) ib IPC/JPCA-6202.
Qhov kev ntsuam xyuas no yog qhov tseem ceeb tshwj xeeb rau FPC siv nyob rau hauv siab -cov av noo ib puag ncig lossis hauv cov khoom siv kho mob uas lub cev tiv tauj yog qhov kev txiav txim siab. Ib qho hluav taws xob tsis tshua muaj hluav taws xob nyeem ntawv tom qab cov av noo feem ntau qhia tias muaj kab mob ionic ntawm lub substrate nto los yog tsis txaus tu tom qab txheej txheem plating.
Ionic Contamination Testing: IPC-TM-650 Txoj Kev 2.3.28B
Ionic contamination yog ntsuas raws li sodium chloride sib npaug hauv micrograms ib square centimeter. Qhov txwv rau Chav Kawm 2 thiab Chav Kawm 3 FPC yog 1.2 micrograms ib square centimeter lossis tsawg dua.
Qhov kev ntsuam xyuas rho tawm cov dej soluble ionic residues los ntawm lub rooj tsavxwm nto siv cov kuab tshuaj thiab ntsuas cov conductivity ntawm cov kua extraction. High ionic contamination theem ntawm FPC tuaj yeem ua rau dendrite kev loj hlob ntawm cov kab nyob ze, ua rau muaj kev cuam tshuam lossis ua tiav luv luv thaum lub sijhawm ua haujlwm.
Qhov kev sim no tau khiav ntawm txhua qhov ntau lawm ntawm peb qhov chaw Dongguan vim qhov tshwm sim ntawm qhov ploj lawm qhov no yog qhov tsis ua haujlwm hauv cheeb tsam uas nyuaj rau kev kuaj mob thiab kim rov qab.
Dynamic Flex Testing: IPC-TM-650 Txoj Kev 2.4.9.1
Rau FPC uas yuav muaj kev rov kho dua tshiab hauv kev pabcuam, dynamic flex testing yog cov txheej txheem kev ruaj ntseg zoo tshaj plaws. Qhov kev sim ntsuas cov qauv nyob ib ncig ntawm lub mandrel ntawm ib lub vojvoog khoov thiab zaus kom txog rau thaum lub voj voog tsis ua haujlwm lossis txog thaum lub voj voog suav suav.
IPC-TM-650 Txoj Kev 2.4.9.1 qhia qhov ntsuas ntsuas nrog rau txoj kab uas hla mandrel (uas txiav txim siab lub vojvoog khoov), tus lej ntawm lub voj voog khiav, thiab cov txheej txheem tsis ua haujlwm (feem ntau qhib Circuit Court lossis ib qho kev txo qis hauv rwb thaiv tsev).
Rau cov neeg siv khoom hnav, ib qho kev qhia tshwj xeeb yog 10,000 cycles ntawm lub vojvoog khoov ntawm 0.5 hli lossis loj dua. Rau kev siv cov cuab yeej siv kho mob, cov lus qhia tshwj xeeb tuaj yeem khiav mus txog 100,000 lub voj voog lossis ntau dua ntawm kev khoov radii. Foldable zaub daim ntawv thov yuav qhia tau 200,000 cycles.
Thaum thov kev ntsuas dynamic flex, qhia meej txog qhov khoov lub vojvoog, lub voj voog suav, thiab seb qhov kev sim no puas khiav ntawm qhov kub thiab txias lossis qhov kub siab tshaj. Kev ntsuas ntawm rho tawm 40 rau ntxiv rau 85 degrees Celsius yog ntau tus neeg sawv cev ntawm kev siv tsheb thiab sab nraum zoov.
Thaum tsim nyog rau lub chaw tsim khoom FPC tshiab, nug cov ntaub ntawv hauv qab no rau IPC / JPCA-6202 cov cai.
IPC-TM-650 kuaj cov cuab yeej siv rau kev kuaj lub zog thiab dielectric zog
Thov IPC-TM-650 cov ntaub ntawv xeem rau tev lub zog, dielectric zog, thiab rwb thaiv tsev tsis kam ntawm thawj kab lus piv txwv. Paub meej tias qhov kev kuaj kab mob ionic tau ua tiav ntawm txhua qhov ntau lawm, tsis yog hauv thawj kab lus. Nug rau daim ntawv tshaj tawm dynamic flex test yog tias koj daim ntawv thov yuav tsum tau rov kho dua. Xyuas kom tseeb tias ENIG thickness yog ntsuas thiab sau tseg rau ib qho khoom xa tuaj.
Ib lub chaw tsim khoom uas tuaj yeem muab cov ntaub ntawv no qhia txog kev tswj xyuas cov txheej txheem thiab kev taug qab uas dhau mus dhau qhov kev kuaj pom yooj yim. Qhov ntawd yog lub hauv paus kev sib koom tes kev ruaj ntseg uas koj xav tau rau Class 2 lossis Class 3 FPC ntau lawm.
