Lintlha tsa moralo oa HDI Boards ke life?

Liboto tsa HDI (High Density Interconnect) li fetohile khetho e ka sehloohong bakeng sa meralo ea sejoale-joale ea elektroniki. Ba fana ka melemo e mengata ho feta liboto tsa potoloho tse hatisitsoeng tsa setso (PCBs), joalo ka sekhahla se phahameng sa potoloho, lintlha tse nyane tsa sebopeho, le ponts'o e ntlafalitsoeng ea matšoao. Leha ho le joalo,menahano e ikhethang ea moralo oa liboto tsa HDI e hloka moralo o hlokolosi le ts'ebetso ho netefatsa ts'ebetso e nepahetseng le ts'epo. Mona re tla hlahloba lintlha tsa bohlokoa tse lokelang ho nahanoa ha ho etsoa boto ea HDI.

1. Miniaturization le sebopeho sa likarolo:

Le leng la mabaka a mantlha a ho sebelisa liboto tsa HDI ke bokhoni ba bona ba ho amohela palo e kholo ea likarolo sebakeng se senyenyane sa maoto. Joaloka moqapi, o tlameha ho nahana ka karolo ea miniaturization le ho rera ka hloko sebopeho sa likarolo. Ho beha likarolo ho na le karolo ea bohlokoa ho fihlelleng moralo o kopaneng ntle le ho senya botšepehi ba matšoao.

Ho ntlafatsa miniaturization, nahana ka ho sebelisa likaroloana tse nyane, tse kopaneng haholoanyane. Ho phaella moo, tšebeliso ea thekenoloji ea holim'a holim'a metsi (SMT) e nolofalletsa ho beha likarolo tse sebetsang hantle, ho fokotsa boholo ba boto ka kakaretso. Leha ho le joalo, etsa bonnete ba hore u hlahloba lintlha tsa mocheso le ho netefatsa mekhoa e lekaneng ea ho pholisa, haholo-holo bakeng sa likarolo tse phahameng tsa matla.

2. Botšepehi ba pontšo le phetiso:

Liboto tsa HDI li ts'ehetsa lits'ebetso tse phahameng tsa maqhubu le lebelo le holimo, kahoo botšepehi ba matšoao bo fetoha taba ea bohlokoa. Ho fokotsa tahlehelo ea matšoao le ho kena-kenana ho bohlokoa e le ho boloka botšepehi ba matšoao. Lintlha tse ling tsa bohlokoa tseo u lokelang ho li hopola ke tsena:

a. Taolo ea Impedans:E netefatsa ho lumellana ho nepahetseng ha impedance ho pholletsa le boto. Sena se ka finyelloa ka khetho e hlokolosi ea bophara ba trace, sebaka le thepa ea dielectric. Ho khomarela litekanyetso tse laoloang tsa impedance tse tobileng ts'ebeliso ea hau ho bohlokoa ho fokotsa ho fokotsa matšoao.

b. Crosstalk e laoloang:Meralo e matla haholo hangata e etsa hore ho be le sebaka se thata ho latela liboto tsa HDI, e leng se lebisang ho crosstalk. Crosstalk e etsahala ha lets'oao le kena-kenana le mesaletsa e haufi, e bakang phokotso ea lets'oao. Ho fokotsa litlamorao tsa crosstalk, sebelisa mekhoa e joalo ka litsela tse fapaneng, ho sireletsa, le likabelo tse nepahetseng tsa sefofane.

c. Botšepehi ba Matla:Ho boloka kabo e tsitsitseng ea matla ho pholletsa le boto ho bohlokoa bakeng sa phetiso e nepahetseng ea mats'oao. Kenyelletsa li-decoupling capacitor tse lekaneng, lifofane tsa fatše, le lifofane tsa matla ho etsa bonnete ba hore ho na le tsela e tlaase ea impedance bakeng sa phetisetso ea matla.

d. Lintlha tsa EMI/EMC:Ha boima ba potoloho bo ntse bo eketseha, ho joalo le ka kotsi ea mathata a Electromagnetic Interference (EMI) le Electromagnetic Compatibility (EMC). Ela hloko mekhoa e nepahetseng ea motheo, maano a ho sireletsa, le li-filters tsa EMI ho fokotsa ts'oaetso ea boto ea HDI ho kena-kenana le motlakase oa kantle.

3. Liphephetso tsa tlhahiso le khetho ea thepa:

Ho theha le ho etsa liboto tsa HDI ho ka hlahisa mathata a fapaneng ka lebaka la ho rarahana ho eketsehileng. Ho khetha lisebelisoa tse nepahetseng le mekhoa ea ho etsa thepa ke ea bohlokoa molemong oa katleho ea moralo. Nahana ka lintlha tse latelang:

a. Ho bokella lera ka moralo:Hangata liboto tsa HDI li na le mekhahlelo e mengata, hangata ka li-stack-ups tse rarahaneng. Rera ka hloko stack-up ho lumellana le sesupo sa tsela e lakatsehang, u ela hloko lintlha tse joalo ka boholo ba boro, ka mofuta (joalo ka sefofu, se patiloeng, kapa microvia), le sebaka sa eona. E nepahetseng ka ho rera e netefatsa ho tsamaisa mats'oao hantle ntle le ho beha ts'epahalo kotsing.

b. Khetho ea Lintho:Khetha thepa e nepahetseng ea laminate ho ipapisitse le ts'ebetso e lakatsehang ea motlakase, litlhoko tsa taolo ea mocheso, le lintlha tsa litšenyehelo. Liboto tsa HDI hangata li itšetleha ka thepa e khethehileng e nang le mocheso o phahameng oa phetoho ea likhalase, lintlha tse tlase tsa ho qhalana, le conductivity e ntle ea mocheso. Ikopanye le barekisi ba thepa ho fumana khetho e nepahetseng ka ho fetisisa.

c. Mamello ea Tlhahiso:The miniaturization le ho eketseha ho rarahaneng ha liboto tsa HDI ho hloka mamello e matla ea tlhahiso. Etsa bonnete ba hore o hlalosa le ho buisana ka mamello ea hau ho moetsi ho netefatsa tlhahiso e nepahetseng le ho lekana.

4. Tšepahala le Mehopolo ea Teko:

Ho tšepahala ha boto ea HDI ho bohlokoa ts'ebetsong e reriloeng. Ho ntlafatsa ho tšepahala le ho nolofatsa ho rarolla mathata, nahana ka lintlha tse latelang tsa moralo:

a. Design for Testability (DFT):Ho kenyelletsa lintlha tsa liteko, joalo ka lintlha tsa phihlello tsa logic analyser kapa boundary-scan test points, ho ka thusa litekong tsa kamora tlhahiso le ho lokisa liphoso.

b. Lintlha tsa mocheso:Kaha liboto tsa HDI hangata li paka palo e kholo ea likarolo sebakeng se senyenyane, taolo ea mocheso e ba ea bohlokoa. Kenya ts'ebetsong mekhoa e nepahetseng ea ho pholisa, joalo ka licheso tsa mocheso kapa li-vias tsa mocheso, ho etsa bonnete ba hore likarolo li sebetsa ka har'a meeli e behiloeng ea mocheso.

c. Lintlha tsa Tikoloho:Utloisisa maemo a tikoloho ao boto ea HDI e tla sebetsa tlas'a eona le ho rala ka nepo. Lintlha tse kang mocheso o feteletseng, mongobo, lerōle le ho sisinyeha li nkoa e le ho etsa bonnete ba hore boto e khona ho mamella tikoloho e reriloeng.

Ka kakaretso, ho rala boto ea HDI ho hloka hore ho nahanoe ka lintlha tse 'maloa tsa bohlokoa ho finyella sekhahla se phahameng sa potoloho, ho ntlafatsa botšepehi ba matšoao, ho netefatsa ho tšepahala, le ho nolofatsa tlhahiso. Ka ho rera ka hloko le ho kenya ts'ebetsong leano la miniaturization, ho nahana ka botšepehi ba matšoao le melao-motheo ea phetisetso, ho khetha lisebelisoa tse loketseng, le ho rarolla mathata a ts'eptjoang, u ka khona ho lemoha bokhoni bo feletseng ba theknoloji ea HDI meralong ea hau.Shenzhen Capel Technology Co., Ltd e 'nile ea ameha ka botebo libotong tsa potoloho ka lilemo tse 15. Ka phallo e matla ea ts'ebetso, bokhoni ba ts'ebetso e tsoetseng pele, lits'ebeletso tsa botekgeniki tsa litsebi, boiphihlelo bo ruileng ba projeke le theknoloji e ncha, re hapile tšepo ea bareki. 'Me nako le nako re ka fumana monyetla oa' maraka bakeng sa morero oa moreki.
