Thaum lub PCB tau sib sau ua ke, V-shaped faib kab ntawm ob lub veneers thiab nruab nrab ntawm cov veneer thiab cov txheej txheem ntug tsim ib "V" zoo;nws tawg thiab sib cais tom qab vuam, yog li nws yog hu uaV-txiav.

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 hauv Circuit Court tau sib sau ua ke.Thaum lub PCBA muab faib, V-Cut Scoring tshuab (Scoring tshuab) feem ntau yog siv los txiav PCB ua ntej.Teem lub voj voog ntawm Scoring, thiab tom qab ntawd thawb nws nyuaj.Qee lub tshuab muaj kev tsim cov khoom noj tsis siv neeg board.Raws li ntev raws li ib lub pob nias, cov hniav yuav cia li txav mus thiab hla txoj hauj lwm ntawm V-Cut ntawm lub rooj tsavxwm los txiav lub rooj tsavxwm.Qhov siab ntawm cov hniav tuaj yeem hloov kho nce lossis nqis kom phim cov tuab ntawm V-txiav sib txawv.

Nco tseg: Ntxiv rau kev siv V-Cut's Scoring, muaj lwm txoj hauv kev rau PCBA sub-boards, xws li Routing, stamp qhov, thiab lwm yam.

Txawm hais tias V-Cut tso cai rau peb kom yooj yim cais lub rooj tsavxwm thiab tshem tawm cov ntug ntawm lub rooj tsavxwm, V-Cut kuj muaj kev txwv rau kev tsim thiab siv.

1. V-Cut tsuas yog txiav ib txoj kab ncaj nraim, thiab ib rab riam mus rau qhov kawg, uas yog hais tias, V-Cut tsuas yog txiav rau hauv txoj kab ncaj nraim los ntawm qhov pib mus rau qhov kawg, nws tsis tuaj yeem tig los hloov txoj kev, tsis tuaj yeem txiav mus rau hauv ib qho me me zoo li tus kws txiav plaub hau.Hla ib kab lus luv luv.

2. Lub thickness ntawm PCB yog nyias thiab tsis haum rau V-Cut grooves.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 grooves yuav rhuav tshem lub zog ntawm tus qauv PCB., Thaum muaj qhov hnyav hnyav muab tso rau ntawm lub rooj tsavxwm nrog V-Cut tsim, 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 welding (nws yog ib qho yooj yim los ua kom tsis muaj vuam lossis luv luv Circuit Court).

3. Thaum lub PCB dhau los ntawm qhov kub ntawm 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.yog tsis haum rau tus txheej txheem thib ob reflow.
