Msonkhano wa PCB, mzere wogawanitsa wooneka ngati V pakati pa ma veneers awiri ndi ma veneers ndi m'mphepete mwa ndondomeko, mu mawonekedwe a "V";
Pambuyo kuwotcherera, imasweka, motero imatchedwa V-CUT.
Cholinga cha V-cut
Cholinga chachikulu chopangira V-cut ndikuwongolera wogwiritsa ntchito kugawa bolodi pambuyo poti gulu ladera lisonkhanitsidwa.PCBA ikagawidwa, makina a V-Cut Scoring nthawi zambiri amagwiritsidwa ntchito kudula PCB pasadakhale ndi ma groove ooneka ngati V.Kugoletsa tsamba lozungulira la Huai Scoring, ndiyeno kukankhira mwamphamvu, makina ena ali ndi mapangidwe odyetserako bolodi, bola ngati batani, tsambalo limangosuntha ndikudula bolodi kudzera pa V-Dulani malo a bolodi, kutalika. wa tsamba Ikhoza kusinthidwa mmwamba ndi pansi kuti ifanane ndi makulidwe a V-Kudula kosiyana.
Chikumbutso: Kuphatikiza pa Scoring wa V-Dulani, pali njira zina za PCBA subboard, monga mayendedwe, dzenje la sitampu, etc.
Ngakhale V-Dulani pa PCB ingathenso kusweka pamanja kapena kusweka pamalo a V-Dulani, tikulimbikitsidwa kuti musawononge pamanja kapena kuswa V-Dulani, chifukwa idzakhudzidwa ndi mphamvu pamene pamanja. PCB ndi wopindika, amene mosavuta chifukwa mbali zamagetsi pa PCBA osokoneza, makamaka mbali capacitor, amene kuchepetsa zokolola ndi kudalirika kwa mankhwala.Mavuto ena amawonekera pang'onopang'ono ngakhale atagwiritsa ntchito nthawi yayitali.
V-Dulani mapangidwe ndi zoletsa kugwiritsa ntchito
Ngakhale V-Cut ikhoza kutithandizira kuti tisiyanitse bolodi mosavuta ndikuchotsa m'mphepete mwa bolodi, V-Cut ilinso ndi zoletsa zamapangidwe ndi kugwiritsa ntchito.
1. V-Cut imatha kudula mizere yowongoka ndikudula mpaka kumapeto.Ndiko kunena kuti, V-Cut imatha kudula mzere ndikudula molunjika kuyambira koyambira mpaka kumapeto.Sichingatembenukire kuti chisinthe njira, komanso sichitha kudula gawo lalifupi ngati ulusi wosoka.Dumphani ndime yaifupi.
2. Makulidwe a PCB ndioonda kwambiri ndipo si oyenera V-Cut groove.Nthawi zambiri, ngati makulidwe a bolodi ndi ochepera 1.0mm, V-Cut ndiyosavomerezeka.Izi ndichifukwa choti V-Cut groove idzawononga mphamvu zamapangidwe a PCB yoyambirira., Pakakhala mbali zolemetsa zomwe zimayikidwa pa bolodi lopangidwa ndi V-Cut, bolodi limakhala losavuta kupindika chifukwa cha kugwirizana kwa mphamvu yokoka, yomwe imakhala yovuta kwambiri pa ntchito yowotcherera ya SMT (yosavuta kuyambitsa kutsekemera kopanda kanthu kapena dera lalifupi).
3. Pamene PCB idutsa kutentha kwakukulu kwa ng'anjo yowonjezereka, bolodiyo idzafewetsa 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., Ndizosavomerezeka kwa njira yachiwiri yobwezeretsanso.
Kutanthauzira kwa mbali ya V-Cut
Nthawi zambiri, V-Cut ili ndi makona atatu a 30 °, 45 ° ndi 60 ° omwe amatha kufotokozedwa.Zomwe zimagwiritsidwa ntchito kwambiri ndi 45 °.
Kukula kokulirapo kwa V-Cut, mbale zambiri m'mphepete mwa bolodi zimadyedwa ndi V-Cut, ndipo dera loyang'anizana ndi PCB liyenera kubwezeredwa kuti lisadulidwe ndi V-Cut kapena kudula V. -Kuwonongeka kukadulidwa.
Pang'ono pang'ono pakona ya V-Cut, mapangidwe a danga a PCB amamveka bwino, koma sibwino kwa moyo wa V-Cut ma saw masamba a PCB wopanga, chifukwa ang'onoang'ono ang'onoang'ono a V-Cut, m'pamenenso amawonekera kwambiri. tsamba la macheka amagetsi.Kuonda kwake, ndikosavuta kuvala ndikuthyola tsamba lake.
