Yuav ua li cas zam luam tawm Circuit Board warping

1. Txo cov nyhuv ntawm qhov kub thiab txias ntawm lub rooj tsavxwm
Txij li [kub] yog lub hauv paus tseem ceeb ntawm kev ntxhov siab ntawm lub rooj tsavxwm, tsuav yog qhov kub ntawm lub qhov cub reflow txo qis los yog qhov ceev ntawm lub rooj tsavxwm cua sov thiab cua txias hauv qhov cub reflow yog qeeb, lub warpage ntawm PCB tuaj yeem txo qis heev.Txawm li cas los xij, lwm yam kev mob tshwm sim tuaj yeem tshwm sim, xws li cov luv luv.

2. Siv daim ntawv Tg siab
Tg yog lub iav hloov pauv kub, uas yog, qhov kub thiab txias ntawm cov khoom hloov ntawm lub khob iav mus rau lub xeev roj hmab.Qhov qis dua Tg tus nqi ntawm cov khoom siv, lub rooj tsavxwm nrawm dua pib muag tom qab nkag mus rau qhov cub reflow, thiab lub sijhawm nws yuav siv los ua cov roj hmab muag muag.Nws kuj tseem yuav ntev dua, thiab qhov deformation ntawm lub rooj tsavxwm yuav yog qhov hnyav dua.Kev siv cov ntawv Tg siab dua tuaj yeem ua rau nws muaj peev xwm tiv taus kev ntxhov siab thiab deformation, tab sis tus nqi ntawm cov khoom siv kuj tseem siab.

3. Ua kom lub thickness ntawm lub rooj tsavxwm Circuit Court
Yuav kom ua tiav qhov sib zog thiab nyias tuab ntawm ntau cov khoom siv hluav taws xob, lub thickness ntawm lub rooj tsavxwm tau raug tso tseg ntawm 1.0mm, 0.8mm, thiab txawm tias 0.6mm.Xws li ib tug tuab yuav tsum ua kom lub rooj tsavxwm los ntawm deformed tom qab dhau los ntawm reflow rauv, uas yog ib qho nyuaj me ntsis.Lub Hoobkas PCB pom zoo tias yog tias tsis muaj qhov yuav tsum tau ua kom lub teeb thiab nyias, lub rooj tsavxwm tuaj yeem nyiam siv lub thickness ntawm 1.6 hli, uas tuaj yeem txo qhov kev pheej hmoo ntawm warpage thiab deformation ntawm PCB pawg thawj coj saib.

4. Txo qhov loj ntawm lub rooj tsav xwm hauv Circuit Court thiab txo cov vaj huam sib luag
Txij li feem ntau cov reflow ncu siv chains los tsav lub Circuit Court board rau pem hauv ntej, qhov loj ntawm lub Circuit Court board yuav dented thiab deformed nyob rau hauv lub reflow qhov cub vim nws tus kheej hnyav, yog li sim muab lub sab ntev ntawm lub Circuit Court board raws li lub board ntug.Nyob rau hauv cov saw ntawm lub reflow rauv, lub concave deformation tshwm sim los ntawm qhov hnyav ntawm lub rooj tsavxwm Circuit Court nws tus kheej yuav raug txo.Qhov no kuj yog vim li cas thiaj li txo cov panels.Uas yog hais tias, thaum dhau lub cub tawg, sim siv lub nqaim sab mus rau perpendicular mus rau lub cub tawg kev taw qhia, uas muaj peev xwm ua tau qhov qis tshaj tus nqi ntawm concave deformation.

5. Siv lub lauj kaub tais diav
Yog tias cov txheej txheem saum toj no nyuaj ua tiav, qhov kawg yog siv lub qhov cub (reflow soldering carrier / template) kom txo tau qhov deformation ntawm lub rooj tsavxwm.Lub hauv paus ntsiab lus uas lub qhov cub lub tais tuaj yeem txo qhov warpage ntawm PCB pawg thawj coj saib yog vim tias cov khoom siv ntawm cov khoom siv yog dav dav.Aluminium alloy los yog cov pob zeb hluavtaws yuav raug siv kom muaj qhov kub thiab txias, yog li lub Hoobkas PCB yuav cia lub rooj tsav xwm hauv Circuit Court dhau los ntawm qhov kub thiab txias thermal expansion ntawm qhov cub reflow thiab txias shrinkage tom qab txias.Lub tais tuaj yeem ua lub luag haujlwm ntawm stabilizing lub rooj tsavxwm Circuit Court.Tom qab qhov kub ntawm lub phaj qis dua tus nqi Tg thiab pib rov qab thiab tawv, qhov loj me tuaj yeem khaws cia.

Yog hais tias ib txheej txheej tais fixture tsis tuaj yeem txo qhov deformation ntawm lub Circuit Board , koj yuav tsum tau ntxiv ib txheej ntawm lub hau rau clamp lub rooj tsav xwm Circuit Court nrog rau sab sauv thiab sab phaj, uas tuaj yeem txo qhov deformation ntawm Circuit Court board los ntawm qhov cub reflow..Txawm li cas los xij, qhov cub lub tais no kim heev, thiab koj yuav tsum tau ntxiv zog rau qhov chaw thiab rov ua dua lub tais.

6. Siv Router hloov V-Cut's sub-board
Txij li thaum V-Cut yuav rhuav tshem lub zog ntawm cov vaj huam sib luag ntawm cov laug cam, sim tsis txhob siv V-Cut sub-board, lossis txo qhov tob ntawm V-Cut.
