2. Ingqibelelo yomqondiso kunye ne-crosstalk

IiPCBs zeHDI eziguquguqukayo zihlala zinemigangatho emininzi, nto leyo iyenza ibaluleke kakhulu ukujongana nemiba yemfezeko yesiginali enje nge-crosstalk, ukungahambelani kwe-impedance, kunye nengxolo. Ezi ngxaki zinokubangela ukuthotywa komqondiso okanye ukuphazamiseka, okunokuchaphazela kakhulu ukusebenza kwesixhobo.

isisombululo:
Abaqulunqi banokuthomalalisa imiba yemfezeko yomqondiso ngokusebenzisa ubuchule obunje ngolawulo lwe-impedance routing, ukwahlula umqondiso, kunye noyilo olufanelekileyo lwenqwelomoya. Isoftware yokulinganisa imfezeko yomqondiso inokusetyenziselwa ukuhlalutya kunye nokwandisa iindlela zomqondiso ukuchonga nayiphi na imiba enokubakho phambi kokuvelisa. Ngokuqwalasela ngononophelo umzila wesignali kunye nokusebenzisa iindlela ezifanelekileyo zokukhusela i-EMI, abaqulunqi banokuqinisekisa imfezeko yomqondiso kunye nokunciphisa i-crosstalk.

3. Ukutshintsha ukusuka kwi-flexibility ukuya kubungqongqo

Utshintsho phakathi kwenxalenye eguquguqukayo kunye nengqongqo yePCB inokudala imingeni yokuthembeka koomatshini kunye noqhagamshelo lombane. Indawo yenguqu eguquguqukayo ifuna ukuyilwa ngononophelo ukuthintela nakuphi na ukugxininiswa koxinzelelo okanye ukusilela komatshini.

isisombululo:
Ukucwangciswa ngokufanelekileyo kwendawo yenguqu eguquguqukayo ukuya kwi-rigid kubalulekile ukuqinisekisa uqhagamshelo lombane oluthembekileyo noluzinzileyo. Abaqulunqi kufuneka bavumele utshintsho olugudileyo kunye nolucothayo kubume boyilo kwaye baphephe ii-engile ezibukhali okanye utshintsho olukhawulezileyo kwicala. Ukusebenzisa izixhobo zokuxhuma eziguquguqukayo kunye ne-stiffeners kunceda ukunciphisa uxinzelelo kunye nokuphucula ukuthembeka koomatshini.

4. Ulawulo lobushushu

Ukulawula ukuchithwa kobushushu kuyinkalo ebalulekileyo yoyilo lwe-HDI eqinile-flex PCB. Ubume obubambeneyo bezi PCB buphumela ekunyukeni koxinzelelo lobushushu, oluchaphazela ukusebenza kunye nexesha elide lamacandelo e-elektroniki.

isisombululo:

Ubuchwephesha bolawulo lobushushu, obufana nokusetyenziswa kweesinki zobushushu, iivent ze-thermal, kunye nokubekwa kwecandelo ngononophelo, kunokunceda ukulahla ubushushu ngokufanelekileyo. Ukongeza, abaqulunqi kufuneka bathathele ingqalelo ukusebenzisa ukuhamba komoya okufanelekileyo kunye neendlela zokupholisa kuzo zonke izixhobo zolwakhiwo ukuqinisekisa ukulahla ubushushu okwaneleyo.

5. Imveliso kunye neNdibano

Inkqubo yokwenziwa kunye nendibano yeePCBs zeHDI eziguquguqukayo zinokuntsonkotha ngakumbi kuneePCB zesintu. Uyilo oluntsonkothileyo kunye neeleya ezininzi zibonelela ngemingeni yendibano, kwaye naziphi na iimpazamo kwinkqubo yokuvelisa zinokukhokelela kwiziphene okanye ukusilela.
