Xa i-PCB idityanisiwe, umgca wokuhlula omile okwe-V phakathi kweeveneer ezimbini kunye naphakathi kwe-veneer kunye ne-program edge yenza i-"V" imilo; yaphulwa kwaye yahlulwe emva kwe-welding, ngoko ibizwa ngokubaI-V-cut.

Injongo ye-V-cut:

Injongo ephambili yokuyila i-V-cut kukuququzelela umqhubi ukuba ahlule ibhodi emva kokuba ibhodi yesiphaluka ihlanganiswe. Xa i-PCBA yahlulwe, umatshini we-V-Cut Scoring (umatshini wokufaka amanqaku) usetyenziselwa ukusika i-PCB kwangaphambili. Jolisa kwincakuba engqukuva yeNqaku, uze uyityhale ngamandla. Abanye oomatshini banoyilo lokutya kwebhodi okuzenzekelayo. Ngethuba nje iqhosha licinezelwe, i-blade iya kuhamba ngokuzenzekelayo kwaye iwele indawo ye-V-Cut yebhodi yesiphaluka ukusika ibhodi. Ukuphakama kwe-blade kunokulungelelaniswa phezulu okanye phantsi ukuhambelana nobukhulu be-V-Cuts eyahlukeneyo.

Isikhumbuzi: Ukongeza ekusebenziseni i-V-Cut's Scoring, kukho ezinye iindlela ze-PCBA sub-boards, ezifana ne-Routing, imingxuma yesitampu, njl.

Nangona i-V-Cut ivumela ukuba sihlukanise ngokulula ibhodi kwaye sisuse umda webhodi, i-V-Cut nayo inemida ekuyilweni nasekusebenziseni.

1. I-V-Cut inokusika kuphela umgca othe tye, kunye nemela enye ukuya ekupheleni, oko kukuthi, i-V-Cut inokusikwa kuphela kumgca othe ngqo ukusuka ekuqaleni ukuya ekupheleni, ayikwazi ukujika ukutshintsha indlela, yaye ayinakunqunyulwa ibe licandelo elincinane njengomgca womthungi. Tsiba umhlathi omfutshane.

2. Ubukhulu bePCB buncinci kakhulu kwaye ayifanelekanga kwi-V-Cut grooves. Ngokuqhelekileyo, ukuba ubukhulu bebhodi bungaphantsi kwe-1.0mm, i-V-Cut ayikhuthazwa. Oku kungenxa yokuba i-V-Cut grooves iya kutshabalalisa amandla okwakhiwa kwe-PCB yoqobo. , Xa kukho iindawo ezinzima ezibekwe ebhodini kunye noyilo lwe-V-Cut, ibhodi iya kuba lula ukugoba ngenxa yobudlelwane bobunzima, obungathandekiyo kakhulu kwi-welding operation ye-SMT (kulula ukubangela i-welding engenanto okanye intambo emfutshane).

3. Xa i-PCB idlula kwiqondo lokushisa eliphezulu le-oven reflow, ibhodi ngokwayo iya kuthambisa kwaye iguqule ngenxa yokuba ubushushu obuphezulu budlula ubushushu beglasi (Tg). Ukuba indawo ye-V-Sika kunye nobunzulu begroove ayilwanga kakuhle, ukuguqulwa kwe-PCB kuya kuba nzima kakhulu. ayihambisani nenkqubo yokubuyisela kwakhona okwesibini.
