Thaum koj cov khoom lag luam daim ntawv qhia hu rau cov ntawv luam tawm yooj yim, qhov sib txawv ntawm kev tsim lub hom phiaj thiab tsim kev muaj tiag tuaj yeem tshem tawm cov npoo nrawm. Kev xaiv FPC tsis ncaj ncees lawm txhais tau hais tias rov ua haujlwm, ncua sijhawm, thiab kev sib tham tsis txaus ntseeg nrog koj pab neeg yuav khoom. Hauv peb qhov kev paub dhau los ntawm CSNT-EMS hauv Dongguan, peb tau pom qhov chaw rov qab mus rau peb lub hauv paus ua rau: tsis meej IPC cov hom phiaj hauv chav kawm, tsis muaj ntaub ntawv hloov pauv, thiab qhov ua tiav qhov tsis sib haum. Phau ntawv qhia no taug kev los ntawm txhua tus kom koj tuaj yeem sau npe cov neeg xa khoom nrog kev ntseeg siab.
Nkag siab txog IPC/JPCA-6202 Requirements for FPC Production
IPC-JPCA-6202 tus qauv qhia peb qhov kev ua tau zoo rau cov ntawv luam tawm yooj yim. Chav Kawm 1 suav nrog cov khoom siv rau cov neeg siv khoom uas qhov tsis xws luag me tsis cuam tshuam rau kev ua haujlwm. Chav Kawm 2 ua haujlwm rau kev lag luam thiab kev sib txuas lus. Chav Kawm 3 yog tshwj tseg rau aerospace thiab cov cuab yeej kho mob uas xoom tsis xws luag yog qhov kev cia siab hauv paus.
Cov pab pawg engineering feem ntau peb ua haujlwm nrog rau Chav Kawm 2 los ntawm lub neej ntawd. Tab sis ntawm no yog qhov ntes: Chav kawm 2 qhov siab rau tus neeg xyuas pib nicks yog wl tsawg dua lossis sib npaug rau ib nrab ntawm -ib nrab ntawm kab dav, thaum Chav Kawm 3 nruj kom wl tsawg dua lossis sib npaug rau ib - peb ntawm kab dav. Yog tias koj daim ntawv thov yog lub ntsuas ntshav qabzib lossis lub ntsuas ntsuas ntsuas, koj xav tau Chav Kawm 3. Kev lees paub qhov no ua ntej tshaj tawm RFQ tshem tawm 80 feem pua ntawm cov kev tsis sib haum xeeb hauv qab.
Tshaj li nick tolerances, IPC/JPCA-6202 qhia qhov tsawg kawg nkaus tev lub zog ntawm 0.49 N ib hli rau conductors thiab 0.34 N ib hli rau coverlay. Cov lej no tseem ceeb thaum lub rooj tsavxwm yuav raug rov ua dua tshiab hauv kev pabcuam.
Khoom Specifications: Tau txais FCCL thiab Coverlay Txoj Cai
Base xaiv cov khoom tsav ob qho tib si nqi thiab flex lub neej. Ob qhov yooj yim tshaj plaws tooj liab clad laminates hauv peb cheeb tsam yog polyimide (PI) thiab polyester (PET). PI ua haujlwm kub siab dua thiab yog qhov kev xaiv ua ntej rau kev sib sau ua ke. PET ua haujlwm rau ib leeg -ib sab boards uas tsis muaj thermal raug tom qab lamination.
Tsis pub dhau PI cov ntaub ntawv, Panasonic R-F777 tau dhau los ua qhov tshwj xeeb ntawm Dongguan-raws li cov tuam txhab vim tias nws lub zog tev ntawm 0.525 N ib hli dhau ntawm IPC/JPCA-6202 Chav Kawm 2 yam tsawg kawg nkaus los ntawm 7 feem pua. R-F775 yog lwm qhov kev xaiv thaum koj xav tau qis profile (VLP) tooj liab rau cov kab zoo hauv qab 0.1 hli kab dav.
Kev xaiv coverlay tseem ceeb npaum li lub hauv paus. Taiflex FHK0515 yog halogen{2}}dawb coverlay dav dav los ntawm Dongguan distributors thiab tau tshaj cov txheej txheem lamination ntawm 170 mus rau 180 degrees Celsius. Yog tias koj lub rooj tsavxwm muaj siab - cov cim qhia zaus, DuPont Pyralux AK nrog DK 3.4 thiab Df 0.004 muab kev tswj xyuas impedance.

Kev xaiv ntog tiav: ENIG, Kub Plating, thiab OSP
Qhov ua tiav siv rau koj cov ntaub qhwv ntsej muag cuam tshuam rau kev sib cuag, tiv thaiv kev tiv thaiv, thiab txee lub neej. Electroless npib tsib xee immersion kub (ENIG) yog qhov kev xaiv tseem ceeb rau cov rooj sib txoos uas ua rau ntau lub voj voog rov qab. Peb ENIG kab khiav nickel thickness ntawm 3 mus rau 6 micrometers thiab kub thickness ntawm 0.05 mus rau 0.125 micrometers ib txheej, uas ntog nyob rau hauv IPC / JPCA-6202 yuav tsum tau.
Rau cov laug cam uas yuav yog tes- soldered nyob rau hauv qis - ntim ntau lawm, organic solderability preservatives (OSP) ua hauj lwm zoo thiab raug nqi tsawg. OSP tsis tuav mus txog ntau lub voj voog rov qab, yog li ua rau koj lub rooj sib txoos ntws mus rau qhov kev txiav txim siab.
Kub plating (nyuaj kub, 0.5 mus rau 1.0 micrometers) yog siv rau cov laug cam nrog cov phooj ywg nquag - thiab - tsis sib haum mus xws li xoom insertion force (ZIF) connectors. Qhov kev ua tiav no ntxiv tus nqi tab sis daws teeb meem kev sib cuag tau zoo.

Daim Ntawv Teev Npe Ua Haujlwm rau Kev Tshawb Fawb Txog FPC Chaw Muag Khoom hauv Suav
Ua ntej kos npe rau daim ntawv xaj, khiav koj tus neeg xa khoom FPC yav tom ntej los ntawm cov chaw kuaj xyuas no. Nug rau IPC/JPCA{10}}6202 Class 2 lossis Class 3 daim ntawv pov thawj raws li muaj. Thov cov ntaub ntawv cov ntaub ntawv rau FCCL, coverlay, thiab nto tiav. Paub meej tias tooj liab thickness kam rau ua: IPC/JPCA{12}}6202 yuav tsum tau plating nruab nrab ntawm 15 micrometers nrog yam tsawg kawg nkaus 8 micrometers ntawm txhua qhov chaw. Tshawb xyuas cov qauv rub tawm lub zog rau cov voj voog flex. Tshawb xyuas kev ua raws cai tsis muaj halogen yog tias koj cov khoom yuav tsum tau ua raws li EU RoHS lossis REACH cov qauv.
Ntawm peb cov nroj tsuag Dongguan, peb sau tag nrho cov khoom hloov pauv hauv kev sau ntawv thiab hloov kho cov neeg tsim khoom ua ntej pib tsim khoom. Tus neeg muag khoom uas tsis tuaj yeem lossis tsis tuaj yeem muab cov ntaub ntawv no yog qhov pheej hmoo uas koj tsis xav tau.
