Mokhoa oa V-scoring o sebelisitsoe lilemo tse ngata tlhahiso ea boto ea potoloho e hatisitsoeng (PCB). Ka theknoloji ea tlhahiso ea PCB e fetohang ka potlako, ho bohlokoa ho hlokomela litataiso tsa morao-rao tsa lintlha tsa PCB tse lokelang ho lateloa le hore na li ka fapana joang le tseo u neng u li sebelisa pele.

The scoring process involves two blades that rotate closely together point-to-point as the PCB moves between the blades. Ts’ebetso ena e batla e ts’oana le ho tšela pizza ka paneng, ho seha pizza ka likotoana tse tšesaane ebe o fetisetsa sehlahisoa kapele mohatong o latelang, o ka ntlafatsang tlhahiso ka kakaretso. Joale o lokela ho sebelisa lintlha ho PCB ea hau neng? What are the potential drawbacks of this process?

Square boto hatisitsoeng oa potoloho

Hore na PCB ea hau e lisekoere kapa e likhutlo li ‘ne, mahlakore ohle a na le mela e otlolohileng mme e ka khaoloa mochining oa V-notch. Potso eo u ka e botsang ke hore, na e loketse ho kaloloa, kapa ho na le libaka tse ling tse hlokang ho lokisoa? Ho ngolisa kapa ho se hlabe? Here are a few reasons for refusing to answer.

Fumana lintlha tse fokolang tsa PCBS

Liboto tsa potoloho tse hatisitsoeng li tšesaane ho feta lisenthimithara tse 0.040 ho thata ho li notch ka mabaka a ‘maloa. Bonyane ba 0.012 “e hlokahala ho boloka kela e nang le sebopeho sa V, kaha lehare (coil) notch blade left e behiloe ka nako e le ngoe notch 0.010” – botebo ba 0.012 “mahlakore ka bobeli bo tla etsa 0.020″ +/- 0.004 ” letlooa le lenyane ho feta 0.040 ”.

Thinner printed circuit boards have some deflection only in the material. Li-PCBS tse tenyetsehang li sebelisa mokhoa o sa tsejoeng oa khefu li ka siea likarolo tse thata ebe li fanyeha likhoele. Ho laola ts’ebetso ea ho beha lintlha ka lisebelisoa tse fokolang le ho lumella litšitiso tse kholo ho thata haholo. Lehare le bohlokoa ho maemo a mamello ea botebo ba notch ho tloha holimo ho ea tlase, mme ho na le lethathamo le tiileng la ho nepahala ho netefatsa hore thepa ea bophara ha e robehe nakong ea kopano. Ha botebo ba notch bo sa leka-lekana lipakeng tsa le letšehali le le letona, karolo e tla ba thata haholo ho e roba, ho siea likhoele le likhahla tse ka robehang.

PCB ka bongata e hapiloe

Ha ho sebelisoa lingoliloeng tse ngata, likarolo tse fapaneng tsa likarolo li ka ba bobebe, tsa baka ho ts’oaroa habonolo, ho senyeha ha lintho le / kapa mathata a kopano.

Parts with smaller ratings

The smaller the square inch of the board, the harder it is to disconnect. Ha boholo ba PCB bo le nyane, mapolanka a motenya ho feta 0.062 “ho thata haholo ho a arola. Ka tlase ho lisenthimithara tse 1 ntlheng efe kapa efe ho ka hloka lisebelisoa tse ling ho arola likarolo.

Score the PCB which is too long

Liboto tse hatisitsoeng tsa potoloho tse nang le X kapa Y e telele (lisenthimithara tse 12 kapa ho feta) li kanna tsa fokola ‘me tsa robeha ha bonolo haeba li ngooa haholo. Ho eketsa likarolo tse boima ho tse seng li ntse li fokola ho ka etsa hore likarolo li robehe nakong ea ts’ebetso, kopano kapa esita le lipalangoang. Ho kenya tšebetsong lintlha tse ngata kapa mokhoa o mongata e ka ba khetho e ntle.

Ho reka poleiti

Haeba u beha li-PCBS tse kholo ho feta 0.096 cm, sebelisa sekema se ts’oanang, ha mahare a mabeli a seha ho kenella ka holim’a laminate, a siea letlooa le 0.020 inches +/- 0.004 inches. Ka holim’a botenya bona, ho thata ho senya, hobane ho khumama ha hoa lekana. Makhasi a maholo a ka sebelisa mokhoa ona bakeng sa mapolanka a matenya, empa ka linako tse ling a ka lebisa mathateng ka koporo ho arohana.

Sesebelisoa sa lintlha

Ho na le lisebelisoa tse fumanehang ho thusa ho tlosa li-PCBS. Leha ho le joalo, e tlameha ho sebelisoa ka nepo le ho beoa leihlo bakeng sa ho nepahala ho thibela tšenyo ea bohale, ho robeha kapa ho ngoapa bokaholimo. Ho sebetsana ka botlalo le li-PCBS tse kopaneng ka botlalo ho lula ho le kotsi.

Add an Angle or radius to the part

Na see se sitisa bokhoni ba ho sebelisa mokhoa oa ho beha lintlha?

Che, empa u ntse u hloka likarolo tse bataletseng ho ngoapa boto. Ka tloaelo, ha u sebelisa mokhoa oa notching, li-PCBS li tla emisa hammoho. Motho ea sehang o seha ka holimo le holimo.

Ho senya ka maqhubu kapa radii, o tlameha ho tlohela sebaka lipakeng tsa PCBS. Sefofane se tloaelehileng sa Router se sebelisa “cutting ea milling” e hlokang bonyane 0.096 ho hloekisa hantle lipakeng tsa likarolo. Ho boetse ho na le litšila tse fokolang lipakeng tsa likarolo. Ha ho khothaletsoe ho sebelisa 0.100 “mekhoa ea ho arola le ho notch lipakeng tsa liboto, leha ho na le lisebelisoa, ho thata haholo ho e roba. Ha sebaka se hlokahala, ho kgothaletswa hore ho sebelisoe sebaka sa 0.200 “kapa sebaka se seholo bakeng sa linoko.
