Yuav ua li cas kom paub qhov kev xav tau ntawm PCB thiab FPC kub ntiv tes

FPC yog ib qho yooj yim luam tawm Circuit Board Board (Flexible Printed Circuit Board, hu ua FPC), uas yog lub rooj tsav xwm Circuit Court ua los ntawm PI (polyimide) zaj duab xis ua cov khoom siv hauv paus thiab laminated nrog tooj liab ntawv ci. Piv nrog rau PCB nruj luam ntawv Circuit Court boards, FPC Circuit Court boards muaj qhov zoo ntawm dawb bending, folding thiab winding. Thaum sib sau ua ke ib yam khoom, FPC tuaj yeem ua tau raws li qhov kev teeb tsa ntawm qhov chaw sab hauv ntawm cov khoom zoo li cov xaim, kom cov khoom tuaj yeem npaj tau arbitrarily nyob rau hauv peb-dimensional qhov chaw, thiab kev sib txuas ntawm cov xaim thiab lub voj voog. board kuj tuaj yeem muab tshem tawm. Yog li ntawd, FPC Cov khoom siv hluav taws xob tuaj yeem ua rau me me thiab ua kom zoo dua qub, thiab kev ntseeg siab ntawm cov khoom tuaj yeem txhim kho tau zoo.

FPC tau siv dav hauv cov khoom lag luam sib txuas lus, khoos phis tawj laptop, cov khoom siv hluav taws xob, aerospace, tub rog cov khoom siv hluav taws xob thiab lwm yam haujlwm.

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm FPC yog tias nws tuaj yeem paub txog kev sib txuas hluav taws xob. Feem ntau muaj ob txoj kev sib txuas uas twb muaj lawm. Ib qho yog siv lub connector los txuas. Txawm hais tias nws yooj yim los siv lub connector los txuas, nws yuav tsum muaj ntau qhov chaw rau kev teeb tsa, thiab qhov kev ntxig tsis ruaj khov. Qhov tsis zoo ntawm cov nqi siab ua rau nws tsuas yog siv rau hauv qee qhov PCB boards nrog qhov chaw loj thiab siab hardness.

Kev sib txuas ntawm lub voj voog ib txwm yog tseem los ntawm kev vuam, tab sis txhawm rau vuam FPC, cov ntiv tes kub yuav tsum tau ua tiav. FPC kub ntiv tes yog thaj chaw uas tsuas yog cov ntawv ci tooj liab sab laug tom qab tshem tawm ob sab PI. Nws cov thickness ultra-thin ntxiv Cov ductility ntawm tooj liab tsis zoo heev, uas ua rau cov ntiv tes kub kawg ntawm FPC tsis tshua muaj zog. Yog li ntawd, cov txheej txheem ua tam sim no feem ntau ntxiv PI txheej rau qhov khoob ntawm tus ntiv tes kub los txhim kho qhov yooj thiab tensile lub zog ntawm tus ntiv tes kub kawg. Txawm li cas los xij, qhov kev nyuaj siab ntawm FPC thiab qhov nyuaj ntawm vuam thiab vuam tawm los tsis tau zoo heev.

FPC kub ntiv tes hauv daim duab ua ntej kuj muaj qhov tsis zoo hauv qab no

1. Lub peev xwm ntawm FPC vuam txoj hauj lwm los tiv thaiv kev ntxhov siab yog tsawg heev, thiab ntau yam teeb meem xws li kev tawg, kub ntiv tes detachment, thiab vuam txoj hauj lwm ntog yog ib qho yooj yim tshwm sim nyob rau hauv kev tsim khoom thiab kev thauj mus los thiab cov txheej txheem ntau lawm;

2. Cov txheej txheem nyuaj ntawm FPC welding txheej txheem nce, thiab nws yog ib qho yooj yim ua rau lub vuam virtual ua rau cov khoom tsis ua hauj lwm;

3. Qhov kev ntxhov siab uas FPC vuam txoj hauj lwm tuaj yeem dais yog me me, uas txo qhov zoo thiab lub neej ntawm cov khoom sib dhos.

Yog li FPC kub ntiv tes puas tuaj yeem laser welded?

Cov lus teb yog yog, txhawm rau daws cov teeb meem uas muaj nyob rau hauv daim duab ua ntej, lub tshuab laser soldering rau cov ntiv tes kub ntawm FPC yog muab, uas dislocates tooj liab foils ntawm ob sab ntawm cov ntiv tes kub ntawm vuam kawg ntawm FPC, uas. txo qhov kev ua haujlwm nyuaj ntawm cov txheej txheem vuam. , txo qhov muaj peev xwm ntawm cov ntiv tes kub tawg thaum vuam, txhim kho cov khoom vuam tawm los; Txhim kho qhov kev ntxhov siab ntawm FPC vuam txoj hauj lwm, txo FPC vuam txoj hauj lwm nyob rau hauv cov txheej txheem ntau lawm. Qhov zoo ntawm cov khoom sib dhos thiab cov khoom siv lub neej.

Paub txog cov kev cai vuam ntawm fpc kub ntiv tes thiab pcba kev twb kev txuas Cheebtsam

1. Qhov siab ntawm cov pins ntawm qhov vuam nto ntawm cov khoom siv ntsaws yog 1.5 txog 2.0 hli. SMD cov khoom yuav tsum tiaj tus ntawm lub rooj tsavxwm, cov pob qij txha yuav tsum du yam tsis muaj burrs thiab me ntsis arc-puab, thiab cov solder yuav tsum tshaj 2/3 ntawm qhov siab ntawm qhov kawg soldering, tab sis yuav tsum tsis txhob siab tshaj qhov siab ntawm soldering. kawg. Tsawg dua tin, spherical solder pob qij txha los yog solder npog thaj ua rau thaj yog tag nrho cov phem;

2. Qhov siab ntawm cov pob qij txha: qhov siab ntawm cov hlua nce toj yuav tsum tsis pub tsawg dua 1 hli rau ib lub vaj huam sib luag, tsis pub tsawg dua 0.5 hli rau ob lub vaj huam sib luag thiab yuav tsum tau nkag mus rau tin.

3. Cov duab ntawm qhov sib koom ua ke: nws yog conical thiab npog tag nrho lub ncoo.

4. Solder sib koom nto: du thiab ci, tsis muaj pob dub, flux thiab lwm yam khib nyiab, tsis muaj spikes, pits, pores, raug tooj liab thiab lwm yam tsis xws luag.

5. Lub zog sib koom ua ke: tag nrho ntub nrog cov ntaub qhwv thiab cov pins, tsis muaj kev sib tsoo cuav thiab tsis tseeb.

6. Hla ntu ntawm cov pob qij txha: Cov ko taw txiav ntawm cov khoom yuav tsum tsis txhob raug txiav mus rau qhov chaw solder kom ntau li ntau tau, thiab tsis muaj qhov tshwm sim tawg ntawm qhov chaw sib cuag ntawm cov pins thiab cov solder. Tsis muaj spikes thiab barbs ntawm tus ntoo khaub lig.

7. Koob lub rooj vuam: Lub rooj zaum koob yuav tsum tau muab tso rau hauv lub rooj zaum hauv qab, thiab txoj hauj lwm yog qhov tseeb thiab cov kev taw qhia raug. Tom qab lub rooj zaum koob yog welded, lub hauv qab ntab qhov siab yuav tsum tsis txhob ntau tshaj 0.5mm, thiab lub rooj zaum lub cev yuav tsum tsis txhob skewed tshaj lub silk screen ncej. Cov kab ntawm cov rooj zaum koob yuav tsum tau khaws cia kom zoo, thiab tsis pub muaj kev cuam tshuam lossis tsis sib xws.
