PCB musangano, V-shaped kupatsanura mutsara pakati pevheji mbiri uye vheji uye mupendero wegadziriro, mu "V" chimiro;
Mushure mekugadzira, inoputika, saka inonzi V-CUT.

Chinangwa cheV-cut
Chinangwa chikuru chekugadzira V-cut ndechekuita kuti mufambisi aparadzanise bhodhi mushure mekunge bhodhi redunhu raungana.Kana PCBA ikakamurwa, muchina weV-Cut Scoring unowanzo shandiswa kucheka PCB pachine nguva neV-shaped grooves.Kurova blade yakatenderedza yeHuai Scoring, wobva waisundidzira nesimba, mimwe michina ine otomatiki bhodhi yekudyisa dhizaini, sekureba sebhatani, blade inozongofamba nekucheka bhodhi kuburikidza neV-Cheka chinzvimbo chedunhu redunhu, kureba. yeblade Inogona kugadziriswa kumusoro uye pasi kuti ienderane nehupamhi hweV-Cuts yakasiyana.

Yeuchidzo: Pamusoro peKugova kweV-Cheka, kune dzimwe nzira dzePCBA sub-board, senge nzira, gomba rechitambi, nezvimwe.

Kunyangwe iyo V-Cheka paPCB inogona zvakare kutyorwa nemaoko kana kutyorwa pachinzvimbo cheV-Cheka, zvinokurudzirwa kuti usatyora kana kutyora V-Cheka, nekuti ichakanganiswa nenzvimbo yekumanikidza kana iwe uchiita. PCB yakakotama, iyo inogona kuita nyore kuita kuti zvikamu zvemagetsi paPCBA zvitsemuke, kunyanya zvikamu zvecapacitor, izvo zvinoderedza goho uye kuvimbika kwechigadzirwa.Mamwe matambudziko achaonekwa zvishoma nezvishoma kunyange mushure menguva yekushandiswa.

V-Cheka dhizaini uye zvirambidzo zvekushandisa
Kunyangwe V-Cheka ichigona kutigonesa kuparadzanisa bhodhi nyore uye kubvisa mipendero yebhodhi, V-Cheka zvakare ine dhizaini uye kushandisa zvirambidzo.

1. V-Cheka inogona kungocheka mitsetse yakarurama uye kucheka kusvika kumagumo.Kureva kuti, V-Cheka inogona kungocheka kuita mutsara uye kucheka zvakananga kubva pakutanga kusvika kumagumo.Haikwanise kutendeuka kuti ichinje kwainoenda, kana kucheka chikamu chipfupi seshinda yekusona.Dzvanya ndima pfupi.

2. Ukobvu hwePCB hwakanyanya kutetepa uye hauna kukodzera V-Cut groove.Kazhinji, kana ukobvu hwebhodhi huri pasi pe1.0mm, V-Cut haina kukurudzirwa.Izvi zvinodaro nekuti iyo V-Cut groove ichaparadza kusimba kweiyo yekutanga PCB., Kana paine zvikamu zvinorema zvakaiswa pabhodhi rakagadzirwa neV-Cut, bhodhi rinova nyore kukotama nekuda kwehukama hwesimba rinokwevera zvinhu pasi, iro risingafadzi zvakanyanya kune SMT welding oparesheni (nyore kukonzera isina chinhu welding kana pfupi pfupi).

3. Apo PCB inopinda nepamusoro pekushisa kwevheni reflow, bhodhi pachayo ichanyorovesa uye inokanganisa nokuti kupisa kwepamusoro kunodarika girasi rekuchinja kwegirazi (Tg).Kana iyo V-Cheka chinzvimbo uye groove kudzika zvisina kugadzirwa zvakanaka, iyo PCB deformation ichave yakakomba., Hazvina kunaka kune yechipiri reflow process.

Angle tsananguro yeV-Cheka
Kazhinji, V-Cut ine makona matatu e30 °, 45 ° uye 60 ° anogona kutsanangurwa.Inonyanya kushandiswa ndeye 45 °.

Iyo yakakura kona yeV-Cheka, mahwendefa akawanda emupendero webhodhi anodyiwa neV-Cheka, uye dunhu riri pakatarisana nePCB rinofanirwa kudzoserwa zvakanyanya kudzivirira kutemwa neV-Cheka kana kucheka V. -Kukuvadza kana wachekwa.

Iyo diki kona yeV-Cheka, zviri nani iyo PCB nzvimbo dhizaini, asi haina kunaka kuhupenyu hweV-Cut saw blades yemugadziri wePCB, nekuti iyo diki yeV-Cut angle, iyo inowedzera. blade yesaha yemagetsi.Iyo yakaonda iyo, zviri nyore kupfeka uye kutyora blade yayo.
