PCB sib dhos, V-shaped faib kab ntawm ob lub veneers thiab veneers thiab txheej txheem ntug, mus rau hauv "V" zoo;
Tom qab vuam, nws tawg, yog li nws yog hu ua V-CUT.

Lub hom phiaj ntawm V-cut
Lub hom phiaj tseem ceeb ntawm kev tsim V-txiav yog los pab txhawb tus neeg teb xov tooj kom faib lub rooj tsavxwm tom qab lub rooj sib tham sib dhos.Thaum PCBA muab faib, V-Cut Scoring tshuab feem ntau yog siv los txiav PCB ua ntej nrog V-shaped grooves.Scoring lub round hniav ntawm Huai Scoring, thiab tom qab ntawd thawb nws nyuaj, qee lub tshuab muaj kev siv lub rooj noj mov tsis siv neeg, ntev npaum li lub pob, cov hniav yuav cia li txav mus thiab txiav lub rooj tsavxwm los ntawm V-Cut txoj hauj lwm ntawm lub rooj tsavxwm, qhov siab. ntawm cov hniav Nws tuaj yeem hloov kho nce thiab nqis kom phim cov tuab ntawm V-txiav sib txawv.

Lus Ceeb Toom: Ntxiv rau qhov Scoring ntawm V-Cut, muaj lwm txoj hauv kev rau PCBA sub-board, xws li routing, stamp qhov, thiab lwm yam.

Txawm hais tias V-Cut ntawm PCB tuaj yeem ua tau manually tawg lossis tawg ntawm txoj haujlwm ntawm V-Cut, nws raug nquahu kom tsis txhob cuam tshuam los yog tawg V-Cut, vim tias nws yuav cuam tshuam los ntawm lub zog taw tes thaum manually. PCB yog khoov, uas tuaj yeem yooj yim ua rau cov khoom siv hluav taws xob ntawm PCBA tawg, tshwj xeeb tshaj yog cov khoom siv capacitor, uas yuav txo tau cov txiaj ntsig thiab kev ntseeg siab ntawm cov khoom.Qee qhov teeb meem yuav maj mam tshwm txawm tias tom qab siv lub sijhawm.

V-Cut tsim thiab siv cov kev txwv
Txawm hais tias V-Cut tuaj yeem pab peb kom yooj yim cais lub rooj tsavxwm thiab tshem tawm cov npoo ntawm lub rooj tsavxwm, V-Cut kuj muaj kev tsim thiab siv cov kev txwv.

1. V-Cut tsuas yog txiav cov kab ncaj thiab txiav mus rau qhov kawg.Uas yog hais tias, V-Cut tsuas yog txiav mus rau hauv ib txoj kab thiab txiav ncaj ntawm qhov pib mus rau qhov kawg.Nws tsis tuaj yeem tig los hloov cov kev taw qhia, thiab tsis tuaj yeem txiav ib ntu luv zoo li cov xov xaws.Hla ib kab lus luv luv.

2. Lub PCB thickness yog nyias thiab nws tsis haum rau V-Cut zawj.Feem ntau, yog tias lub thickness ntawm lub rooj tsavxwm tsawg dua 1.0mm, V-Cut tsis pom zoo.Qhov no yog vim V-Cut groove yuav rhuav tshem cov txheej txheem lub zog ntawm thawj PCB., Thaum muaj cov khoom hnyav muab tso rau ntawm lub rooj tsavxwm tsim nrog V-Cut, lub rooj tsavxwm yuav yooj yim khoov vim kev sib raug zoo ntawm lub ntiajteb txawj nqus, uas yog qhov tsis zoo rau kev ua haujlwm ntawm SMT vuam (yooj yim ua rau khoob vuam lossis luv luv).

3. Thaum lub PCB mus txog qhov kub ntawm lub qhov cub reflow, lub rooj tsavxwm nws tus kheej yuav soften thiab deform vim tias qhov kub siab tshaj qhov kub hloov pauv iav (Tg).Yog tias V-Cut txoj hauj lwm thiab qhov qhov tob tsis tau tsim zoo, PCB deformation yuav hnyav dua., Nws yog unfavorable rau theem nrab reflow txheej txheem.

Lub kaum sab xis ntawm V-Cut
Feem ntau hais lus, V-Cut muaj peb lub kaum sab xis ntawm 30 °, 45 ° thiab 60 ° uas tuaj yeem txhais tau.Feem ntau siv yog 45 °.

Qhov ntau dua lub kaum sab xis ntawm V-Cut, ntau daim hlau ntawm ntug ntawm lub rooj tsavxwm tau noj los ntawm V-Cut, thiab lub voj voog ntawm lub PCB rov qab yuav tsum tau thim rov qab ntau dua kom tsis txhob raug txiav los ntawm V-Cut lossis txiav V. - Kev puas tsuaj thaum txiav.

Qhov me dua lub kaum sab xis ntawm V-Cut, qhov zoo dua ntawm PCB qhov chaw tsim theoretically, tab sis nws tsis zoo rau lub neej ntawm V-Cut pom cov hniav ntawm PCB cov chaw tsim khoom, vim tias qhov me me ntawm V-Cut lub kaum sab xis, qhov ntau dua. hniav ntawm hluav taws xob saw.Qhov thinner nws yog, qhov yooj yim dua nws yog hnav thiab tawg nws cov hniav.
