Ob Chav-PCB

Cov lus piav qhia luv luv:


Khoom Nthuav dav

Kev siv cov tuab tuab ntawm cov khoom yog qhov tseem ceeb rau kev tsim tsev FR4 PCBS. Thickness yog ntsuas hauv nti, xws li txhiab, nti, lossis millimeters. Muaj ob peb yam yuav tau xav txog thaum xaiv khoom siv FR4 rau koj PCB. Cov lus qhia hauv qab no yuav  piv cov kev xaiv koj:

Double-Sided-PCB (3)

1. Xaiv cov khoom siv FR4 nyias rau tsim cov vaj huam sib luag nrog qhov chaw txwv. Cov ntaub ntawv nyias nyias tuaj yeem txhawb nqa cov khoom sib txawv uas xav tau los tsim lub cuab yeej, xws li Bluetooth txuas, USB txuas, thiab lwm yam. Lawv tseem tsim nyog rau cov phiaj xwm loj uas cov kws tshaj lij xav kom tsom lub chaw txuag qauv.

 

2. nyias cov ntaub ntawv FR4 haum rau cov ntawv thov xav kom yauv. Piv txwv li, siv cov ntaub ntawv me me rau tsheb thiab kev kho mob PCB yog qhov zoo vim tias cov PCBs no

yuav tsum tau khoov duav tas li.

Zam kev xaiv cov ntaub ntawv nyias rau cov qauv tsim PCB zoo, vim tias qhov no nce ntau qhov kev pheej hmoo ntawm kev puas tsuaj lossis lub rooj tsav xwm hauv Circuit Court tawg.

 

3. Lub thickness ntawm cov khoom tuaj yeem cuam tshuam qhov nyhav ntawm cov ntawv luam tawm Circuit Court thiab kuj tseem tuaj yeem cuam tshuam cov khoom sib xyaw. Qhov no txhais tau tias cov khoom siv me me FR4 yuav ua kom yooj yim rau kev tsim cov teeb hluav taws xob, uas ua rau cov khoom siv hluav taws xob me me. Cov khoom hnyav no tau ntxim nyiam thiab yooj yim thauj.

Thaum twg kom tsis txhob siv cov khoom siv FR4, cov khoom siv FR4 tsis yog qhov kev xaiv zoo yog tias koj daim ntawv thov yuav tsum muaj ib qho hauv qab no: Kev tiv thaiv tshav kub zoo: FR4 tsis pom zoo yog tias PCB siv rau hauv qhov chaw sov. Piv txwv li, cov khoom siv FR4 tsis yog qhov kev xaiv zoo rau PCB hauv kev siv aerospace.

Lead-free welding: Yog tias koj cov neeg siv khoom yuav tsum A PCB ua raws RoHS, yuav tsum siv cov vuam txhuas dawb. Thaum lub sij hawm tsis pub cov hmoov txhuas txhuas, qhov kub tsis kam rov qab tuaj yeem mus txog qhov siab kawg ntawm 250 ° C, thiab vim nws qhov kub tsis kam, cov khoom siv FR4

tiv tsis tau nws.

Cov teeb liab loj heev: Thaum raug rau cov teeb liab loj, FR4 phaj tsis tuaj yeem tuav ruaj khov cuam tshuam. Yog li ntawd, kev hloov pauv hloov thiab yuav cuam tshuam rau kev ncaj ncees ntawm lub teeb liab.

 

Vim tias lawv cov npe nrov thiab kev siv dav dav, niaj hnub no nws yooj yim mus nrhiav FR4 PCB cov ntaub ntawv nyob rau hauv kev ua lag luam nrog ntau yam ntawm cov ntsiab lus thiab cov haujlwm. Cov kev xaiv nplua nuj zoo no qee zaum ua rau kev xaiv tsis yooj yim. Hauv qhov no, nws yog qhov tseem ceeb los tham txog koj cov kev xav tau nrog lub chaw tsim khoom.
