Pamene PCB yasonkhanitsidwa, mzere wogawanitsa wofanana ndi V pakati pa zitsulo ziwiri ndi pakati pa nthiti ndi m'mphepete mwa ndondomeko zimapanga mawonekedwe a "V";wathyoledwa ndi kupatukana pambuyo pa kuwotcherera, kotero umatchedwaV-kudula.

Cholinga cha V-cut:

Cholinga chachikulu chopangira V-cut ndikuwongolera wogwiritsa ntchito kugawa bolodi pambuyo poti gulu ladera lisonkhanitsidwa.Pamene PCBA yagawidwa, makina a V-Cut Scoring (Makina ogoletsa) amagwiritsidwa ntchito kudula PCB pasadakhale.Yang'anani pa tsamba lozungulira la Scoring, ndiyeno mukankhireni mwamphamvu.Makina ena ali ndi mapangidwe opangira chakudya chamagulu.Bola batani likakanikiza, tsambalo limangosuntha ndikuwoloka V-Cut ya bolodi ladera kuti lidule bolodi.Kutalika kwa tsamba Kutha kusinthidwa mmwamba kapena pansi kuti mufanane ndi makulidwe a V-Kudula kosiyana.

Chikumbutso: Kuphatikiza pa kugwiritsa ntchito V-Cut's Scoring, pali njira zina zama board ang'onoang'ono a PCBA, monga Routing, mabowo masitampu, ndi zina.

Ngakhale V-Cut imatilola kuti tisiyanitse bolodi mosavuta ndikuchotsa m'mphepete mwa bolodi, V-Cut imakhalanso ndi malire pakupanga ndi kugwiritsa ntchito.

1. V-Cut imangodula mzere wowongoka, ndipo mpeni umodzi mpaka kumapeto, ndiko kunena kuti, V-Cut imatha kudulidwa mzere wowongoka kuyambira pachiyambi mpaka kumapeto, sungatembenuke kuti isinthe njira, ndiponso sichingadulidwe m’kagawo kakang’ono ngati chingwe cha telala.Dumphani ndime yaifupi.

2. Makulidwe a PCB ndioonda kwambiri ndipo si oyenera V-Cut grooves.Nthawi zambiri, ngati makulidwe a bolodi ndi ochepera 1.0mm, V-Cut ndiyosavomerezeka.Izi ndichifukwa choti ma V-Cut grooves awononga mphamvu zamapangidwe a PCB yoyambirira., Pakakhala mbali zolemetsa zomwe zimayikidwa pa bolodi ndi mapangidwe a V-Cut, bolodi lidzakhala losavuta kupindika chifukwa cha kugwirizana kwa mphamvu yokoka, yomwe ili yovuta kwambiri pa ntchito yowotcherera ya SMT (ndizosavuta kuyambitsa kuwotcherera opanda kanthu kapena dera lalifupi).

3. Pamene PCB ikudutsa kutentha kwakukulu kwa ng'anjo yowonjezereka, bolodi lokha lidzafewetsa ndi kupunduka chifukwa kutentha kwakukulu kumaposa kutentha kwa galasi (Tg).Ngati malo a V-Cut ndi kuya kwake sikunapangidwe bwino, kusintha kwa PCB kumakhala koopsa kwambiri.sizikugwirizana ndi njira yachiwiri yobwezeretsanso.
