Indibano ye-PCB, umgca wokwahlula okwe-V phakathi kwee-veneers ezimbini kunye ne-edge yenkqubo, ibe yi-"V" imilo;
Emva kwe-welding, iyaphuka, ngoko ibizwa ngokuba yi-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 usetyenziselwa ukusika i-PCB kwangaphambili kunye ne-V-shaped grooves.Ukufaka iblade engqukuva ye-Huai Scoring, kwaye emva koko uyityhale ngamandla, abanye oomatshini banoyilo lokutya kwebhodi oluzenzekelayo, nje ngokuba iqhosha, iblade iya kuhamba ngokuzenzekelayo kwaye inqumle ibhodi ngesikhundla se-V-Sika sebhodi yesekethe, ukuphakama. yeblade Inokulungiswa phezulu naphantsi ukuze ihambelane nobukhulu be-V-Cuts eyahlukeneyo.

Isikhumbuzo: Ukongeza kwi-Scoreing ye-V-Sika, kukho ezinye iindlela ze-PCBA sub-board, ezifana nendlela, umngxuma wesitampu, njl.

Nangona i-V-Sika kwi-PCB inokuphinda yaphulwe ngesandla okanye yaphulwe kwindawo ye-V-Sika, kuyacetyiswa ukuba ungayiphuli okanye uyiphule i-V-Sika ngesandla, kuba iya kuchaphazeleka ngamandla amandla xa ngesandla. I-PCB igobile, enokubangela ukuba iindawo zombane kwi-PCBA ziqhekeke, ngokukodwa iindawo ze-capacitor, eziya kunciphisa isivuno kunye nokuthembeka kwemveliso.Ezinye iingxaki ziya kubonakala ngokuthe ngcembe nasemva kwexesha lokusetyenziswa.

V-Sika uyilo kunye nezithintelo zokusetyenziswa
Nangona i-V-Sika inokusilungiselela ukuba sihlukanise ngokulula ibhodi kwaye sisuse imiphetho yebhodi, i-V-Sika nayo inezithintelo zoyilo kunye nokusetyenziswa.

1. I-V-Cut inokusika kuphela imigca ethe tye kwaye inqumle ukuya ekupheleni.Oko kukuthi, i-V-Sika inokusika kuphela kumgca kwaye isike ngokuthe ngqo ukusuka ekuqaleni ukuya ekupheleni.Ayinakujika itshintshe indlela, ingenako nokusika icandelo elifutshane njengomsonto wokuthunga.Tsiba umhlathi omfutshane.

2. Ubungqingqwa bePCB bubhityile kakhulu kwaye ayifanelekanga kwi-V-Cut groove.Ngokuqhelekileyo, ukuba ubukhulu bebhodi bungaphantsi kwe-1.0mm, i-V-Cut ayikhuthazwa.Oku kungenxa yokuba i-V-Cut groove iya kutshabalalisa amandla okwakhiwa kwe-PCB yoqobo., Xa kukho iindawo ezinzima ezibekwe kwibhodi eyenzelwe nge-V-Cut, ibhodi iba lula ukugoba ngenxa yobudlelwane bobunzima, obungathandekiyo kakhulu kwi-welding operation ye-SMT (kulula ukubangela i-welding engenanto okanye isiphaluka esifutshane).

3. Xa i-PCB idlula kwiqondo lokushisa eliphezulu le-oven reflow, ibhodi ngokwayo iya kuthamba 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., Ayithandeki kwinkqubo yokubuyisela kwakhona okwesibini.

Inkcazo ye-Angle ye-V-Sika
Ngokuqhelekileyo, i-V-Cut ineengile ezintathu ze-30 °, 45 ° kunye ne-60 ° ezinokuchazwa.Eyona isetyenziswa ngokuqhelekileyo yi-45 °.

I-angle enkulu ye-V-Sika, iiplate ezininzi zomphetho webhodi zidliwa yi-V-Sika, kunye nesekethe kwi-PCB echaseneyo kufuneka ihoxiswe ngakumbi ukuphepha ukunqunyulwa kwe-V-Sika okanye ukusika i-V. -Umonakalo xa usikiwe.

Incinci i-engile ye-V-Sika, i-PCB ingcono uyilo lwendawo ngokwethiyori, kodwa ayilunganga kubomi be-V-Cut saw blades yomenzi we-PCB, kuba i-engile ye-V-Sika incinci, kokukhona iblade yesarha yombane.Ibhityile, kulula ukuyinxiba kwaye iqhekeze incakuba yayo.
