U bona likarolo tse robeli tsa moralo ho PCB

Ho bohlokoa ho utloisisa le ho khetholla likarolo tsa PCB. Ho utloisisa hantle botenya hantle ba PCB, khethollo e ntle e hlokahala ho netefatsa hore PCB e sebetsa ka katleho e phahameng. The following layers are typically seen in stacked PCBS. These may vary, depending on the number of layers, the designer, and the design itself.

L mechanical layer

Ena ke lera la mantlha la PCB. It is used as the outline of the circuit board. This is the basic physical framework of a PCB. Lera lena le boetse le nolofalletsa moqapi ho tseba sebaka se nepahetseng sa liliba le ho seha.

L boloka lera

Lera lena le ts’oana le lera la mochini hobane le ka sebelisoa e le moeli. Leha ho le joalo, ts’ebetso ea lera e ts’oereng ke ho hlalosa pherekano ea ho beha likarolo tsa motlakase, likhoele tsa potoloho, jj. Ha ho motsoako kapa potoloho e ka behoang kantle ho moeli ona. Lera lena le fokotsa mehala ea lisebelisoa tsa CAD libakeng tse itseng.

L routing lera

Lera la routing le sebelisoa ho hokela likarolo. Likarolo tsena li ka fumaneha ka lehlakoreng le leng la boto ea potoloho. Ho beoa ha mekato ho ea ho moqapi, ea etsang liqeto ho latela ts’ebeliso le likarolo tse sebelisitsoeng.

L Sefofane sa fatše le sefofane

Dikarolo tsena ke tsa bohlokoa ho ts’ebetso e nepahetseng ea PCB. Ground grounding and distribution of grounding throughout the circuit board and its components. Lera la motlakase, ka lehlakoreng le leng, le hoketsoe ho le leng la mehato e fumanehang ho PCB ka boeona. Dikarolo bobeli ka hlaha ka holimo, tlase, ‘me roba lipoleiti tsa PCB ho.

L Ho arola sefofane

Sefofane se arohaneng ha e le hantle ke sefofane sa motlakase se arohaneng. Mohlala, sefofane sa motlakase se ka sekepeng se ka aroloa habeli. Halofo e le ‘ngoe ea sefofane sa motlakase e ka hokahanngoa le + 4V’ me halofo e ‘ngoe e ea ho -4V. Kahoo, likarolo tsa board li ka sebetsa ka mehato e ‘meli e fapaneng ho latela likhokahano tsa tsona.

L Sekoahelo / sekoahelo sa skrine

The silkscreen layer is used to implement text markers for components placed on top of the board. Ho koahela ho etsa mosebetsi o ts’oanang ntle le tlase ea poleiti. Likarolo tsena li thusa molemong oa ho etsa le ho etsa litšitiso.

L ho tjheseletsa lera ho tjheseletsa

Mehala ea koporo le masoba a mapolanka a potoloho ka linako tse ling ho thoe ke likoaelo tse sireletsang tsa likarolo tsa solder. Lera lena le boloka lerōle, lerōle, mongobo le lintlha tse ling tsa tikoloho hole le boto.

L lera la solder

Sebelisa peista ea solder kamora ho hloa bokaholimo ba kopano. E thusa ho kopanya likarolo ho boto ea potoloho. E boetse e nolofalletsa phallo ea mahala ea solder ka PCB e nang le likarolo tse holim’a metsi.

Likarolo tsena kaofela li kanna tsa se be teng ka PCB e le ‘ngoe. Lisebelisoa tsena li ipapisitse le moralo oa boto ea potoloho e hatisitsoeng. Likarolo tsena tsa moralo li thusa ho hakanya botenya bo felletseng ba PCB ha botenya bo bong le bo bong ba micron bo baloa. Lintlha tsena li tla u thusa ho boloka mamello e thata e fumanoang mererong e mengata ea PCB.
