Kana PCB yakaunganidzwa, mutsara wekuparadzanisa wakaita V pakati pevheji mbiri uye pakati pevheji uye mupendero wekugadzirisa unoumba "V" chimiro; inoputsika uye inoparadzaniswa mushure mekuputika, saka inodanwaV-kucheka.

Chinangwa cheV-cut:

Chinangwa chikuru chekugadzira V-cut ndechekuita kuti mushandi aparadzanise bhodhi mushure mokunge bhodhi redunhu raungana. Kana iyo PCBA yakakamurwa, iyo V-Cut Scoring muchina (Scoring muchina) inowanzo shandiswa kucheka PCB pamberi. Nangisa pa round blade ye Scoring, wobva waisundidzira zvine simba. Mimwe michina ine dhizaini yekudyisa otomatiki. Chero bedzi bhatani rakadzvanywa, blade inongofamba uye kuyambuka chinzvimbo cheV-Cheka chebhodhi redunhu kuti ucheke bhodhi. Kureba kweblade Inogona kugadziriswa kumusoro kana pasi kuti ienderane nehupamhi hweV-Kutema kwakasiyana.

Chiyeuchidzo: Pamusoro pekushandisa V-Cut's Scoring, kune dzimwe nzira dzePCBA sub-boards, senge Routing, maburi echitambi, nezvimwe.

Kunyange zvazvo V-Cheka ichitibvumira kuparadzanisa bhodhi nyore nyore uye kubvisa mupendero webhodhi, V-Cheka zvakare ine zvisingakwanisi mukugadzira nekushandisa.

1. V-Cheka inogona chete kucheka mutsara wakatwasuka, uye banga rimwe kusvika kumagumo, kureva kuti, V-Cheka inogona kungotemwa kuita mutsara wakatwasuka kubva pakutanga kusvika kumagumo, haigone kutendeuka kushandura nzira, uyewo haigoni kucheka muchikamu chiduku setambo yokusona. Dzvanya ndima pfupi.

2. Ukobvu hwePCB hwakanyanya kutetepa uye hauna kukodzera V-Cut grooves. Kazhinji, kana ukobvu hwebhodhi huri pasi pe1.0mm, V-Cut haina kukurudzirwa. Izvi zvinodaro nekuti iyo V-Cut grooves ichaparadza kusimba kweiyo yekutanga PCB. , Kana paine zvikamu zvinorema zvakaiswa pabhodhi neiyo V-Cheka dhizaini, bhodhi richava nyore kukotama nekuda kwehukama hwesimba rinokwevera zvinhu pasi, izvo zvisingafadzi zvakanyanya kune iyo SMT welding oparesheni (zviri nyore kukonzera isina chinhu welding kana short circuit).

3. Apo PCB inopfuura nepakati pekushisa kwepamusoro 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. haina kukodzera kune yechipiri reflow process.
