Lapho i-PCB ihlanganiswa, umugqa ohlukanisayo omise okuka-V phakathi kwama-veneers amabili naphakathi kwe-veneer kanye nonqenqema lwenqubo wenza umumo othi “V”; iphukile futhi ihlukaniswe ngemuva kokushisela, kubizwa kanjaloI-V-cut.

Inhloso ye-V-cut:

Inhloso eyinhloko yokuklama i-V-cut ukusiza opharetha ukuthi ahlukanise ibhodi ngemva kokuba ibhodi lesifunda lihlangene. Uma i-PCBA ihlukaniswa, umshini wokushaya amagoli we-V-Cut (umshini wokushaya) ngokuvamile usetshenziselwa ukusika i-PCB kusenesikhathi. Khomba ku-blade eyindilinga Yokushaya Amaphuzu, bese uyiphusha ngamandla. Eminye imishini inomklamo wokuphakela ibhodi okuzenzakalelayo. Uma nje inkinobho icindezelwe, i-blade izohamba ngokuzenzakalelayo futhi iwele indawo ye-V-Cut yebhodi lesifunda ukusika ibhodi. Ukuphakama kwe-blade Kungalungiswa phezulu noma phansi ukuze kufane nogqinsi lwama-V-Cuts ahlukene.

Isikhumbuzi: Ngokungeziwe ekusebenziseni i-V-Cut's Scoring, zikhona ezinye izindlela zamabhodi amancane e-PCBA, njenge-Routing, izimbobo zezitembu, njll.

Nakuba i-V-Cut isivumela ukuthi sihlukanise kalula ibhodi futhi sisuse umkhawulo webhodi, i-V-Cut nayo inemikhawulo ekuklanyeni nasekusetshenzisweni.

1. I-V-Cut ingasika kuphela umugqa oqondile, nommese owodwa kuze kube sekugcineni, okusho ukuthi, i-V-Cut ingasikwa ibe umugqa oqondile kusukela ekuqaleni kuya ekugcineni, ayikwazi ukujika ukuze iguqule isiqondiso, futhi ayinakusikwa ibe ingxenye encane njengomugqa womthungi. Yeqa isigaba esifushane.

2. Ugqinsi lwe-PCB mncane kakhulu futhi ayilungele i-V-Cut grooves. Ngokuvamile, uma ubukhulu bebhodi bungaphansi kuka-1.0mm, i-V-Cut ayinconywa. Lokhu kungenxa yokuthi i-V-Cut grooves izocekela phansi amandla esakhiwo se-PCB yasekuqaleni. , Uma kunezingxenye ezisindayo ezibekwe ebhodini ngomklamo we-V-Cut, ibhodi lizoba lula ukugoba ngenxa yobudlelwane bokudonsela phansi, okungekuhle kakhulu ekusebenzeni kwe-SMT welding (kulula ukubangela ukushisela okungenalutho noma isifunda esifushane).

3. Uma i-PCB idlula ekushiseni okuphezulu kwehhavini lokugeleza kabusha, ibhodi ngokwalo lizothamba futhi likhubazeke ngoba izinga lokushisa eliphakeme lidlula izinga lokushisa lokushintsha kwengilazi (Tg). Uma indawo ye-V-Cut nokujula kwe-groove kungaklanywanga kahle, ukuguqulwa kwe-PCB kuzoba kubi kakhulu. ayihambisani nenqubo yesibili yokugeleza kabusha.
