Uyisombulula njani ingxaki yolawulo lobungakanani kunye nokutshintsha komgangatho we-6-layer PCB: uphononongo ngononophelo lwendawo yobushushu obuphezulu kunye noxinzelelo lomatshini

Intshayelelo

Ibhodi yesekethe eprintiweyo (PCB) uyilo kunye noveliso lujongene nemingeni emininzi, ngakumbi ekugcineni ulawulo lwe-dimensional kunye nokunciphisa ukuhluka kwe-dimensional. Oku kuyinyani ngakumbi kwi-6-layer PCBs eziphantsi kobushushu obuphezulu kunye noxinzelelo lomatshini. Kule post blog, siza kuphonononga ezinye izicwangciso ezisebenzayo kunye nobuchule ukoyisa le miba kwaye siqinisekise uzinzo kunye nokuthembeka PCBs ezinjalo.

Qonda ingxaki

Ukuze kulungiswe ngokufanelekileyo nayiphi na ingxaki, kubalulekile ukuqonda kuqala unobangela wayo. Kwimeko yokulawula ubungakanani kunye nokutshintsha kwe-dimensional ye-6-layer PCBs, izinto ezimbini eziphambili zidlala indima ebalulekileyo: indawo yokushisa ephezulu kunye noxinzelelo lomatshini.

Indawo yobushushu obuphezulu

Iindawo eziphakamileyo zokushisa, zombini ngexesha lokusebenza kunye nokuveliswa, kunokubangela ukwanda kwe-thermal kunye nokunciphisa ngaphakathi kwe-PCB imathiriyeli. Oku kunokubangela utshintsho kubukhulu kunye nobukhulu bebhodi, ukuphazamisa ukusebenza kwayo jikelele. Ukongeza, ubushushu obuninzi bunokubangela ukuba ijoyinti ye-solder ibe buthathaka okanye iphuke, kubangele utshintsho olungakumbi.

Uxinzelelo lomatshini

Ukuxinezeleka komatshini (okufana nokugoba, ukuphambuka okanye ukungcangcazela) nako kunokuchaphazela ulawulo lwe-dimensional kunye nokuzinza kwe-dimensional ye-6-layer PCBs. Xa ziphantsi kwamandla angaphandle, izinto zePCB kunye namacandelo anokukhubaza ngokwasemzimbeni, okunokuthi kutshintshe imilinganiselo yawo. Oku kubaluleke kakhulu kwizicelo apho iPCB ihlala iphantsi kwentshukumo okanye uxinzelelo lomatshini.

Izisombululo kunye neTekhnoloji

1. Ukukhetha izinto eziphathekayo

Ukukhetha izinto ezifanelekileyo kubalulekile ekunciphiseni ulawulo lwe-dimensional kunye nokwahluka kwe-dimensional kwi-6-layer PCBs. Khetha izinto ezine-coefficient ephantsi yokwandiswa kwe-thermal (CTE) njengoko zingenakuchaphazeleka kakhulu ekuguquguqukeni kwe-thermal. Iilaminates zobushushu obuphezulu, njenge-polyimide, zinokusetyenziselwa ukomeleza uzinzo lwe-dimensional kumaqondo obushushu aphezulu.

2. Ulawulo lobushushu

Ukuphumeza iindlela ezisebenzayo zokulawula ubushushu kubalulekile ekujonganeni nemekobume yobushushu obuphezulu. Ukuqinisekisa ukuchithwa kobushushu ngokufanelekileyo ngokusetyenziswa kweesinki zobushushu, i-vias ye-thermal, kunye neepads ze-thermal kunceda ukugcina ukusabalalisa ubushushu obuzinzileyo kuyo yonke i-PCB. Oku kunciphisa amandla okwanda kwe-thermal kunye nokucutha, ukunciphisa imiba yokulawula i-dimensional.

3. Ukunciphisa uxinzelelo lomatshini

Ukuthatha amanyathelo okunciphisa kunye nokusasaza uxinzelelo lomatshini kunokuphucula kakhulu uzinzo lwe-dimensional ye-6-layer PCBs. Ukuqiniswa kwebhodi kunye nezakhiwo zenkxaso okanye ukuphumeza i-stiffeners kunokunceda ukunciphisa ukugoba kunye nokuphambuka, ukuthintela imiba yokulawula i-dimensional. Ukongeza, ukusetyenziswa kwetekhnoloji yokunciphisa i-vibration kunokunciphisa impembelelo ye-vibration yangaphandle kwi-PCB.

4. Uyilo lokuthembeka

Ukuyila ii-PCBs ngokuthembeka engqondweni kudlala indima ebalulekileyo ekunciphiseni ukwahluka kwe-dimensional. Oku kubandakanya ukuqwalaselwa kwemiba efana nokulandela umkhondo, ukubekwa kwecandelo, kunye nokupakishwa ko maleko. Umkhondo ocwangcisiweyo ngokucokisekileyo kunye neenqwelomoya ezisebenzayo zomhlaba zinciphisa amathuba okuthotywa komqondiso ngenxa yeenguqu zedimensional. Ukubekwa kwecandelo ngokufanelekileyo kunokuthintela iindawo ezishushu ekuveliseni ubushushu obugqithisileyo, kuthintele ngakumbi imiba yolawulo lobungakanani.

5. Inkqubo yokuvelisa eyomeleleyo

Ukusetyenziswa kweenkqubo zokuvelisa eziphucukileyo ezibeka iliso ngokusondeleyo kwaye zilawule iimeko zobushushu zinokunceda kakhulu ukugcina ulawulo lwe-dimensional kunye nokunciphisa utshintsho lwe-dimensional. Ubuchwephesha be-welding obuchanekileyo kunye nokusabalalisa ukushisa okuchanekileyo ngexesha lokudibanisa kunceda ukuqinisekisa ukuba i-solder joints eqinile kwaye ethembekileyo. Ukongezelela, ukuphumeza iinkqubo ezifanelekileyo zokuphatha kunye nokugcinwa ngexesha lokuvelisa kunye nokuthunyelwa kunokunciphisa utshintsho olubangelwa luxinzelelo lomatshini.

Ukuququmbela

Ukufezekisa ulawulo oluchanekileyo lwe-dimensional kunye nokuzinza kwe-dimensional kwi-PCB ye-6-layer, ngakumbi kwiindawo ezinobushushu obuphezulu kunye neemeko zoxinzelelo lomatshini, zibonakalisa imingeni ekhethekileyo. Le mingeni inokoyiswa ngokukhethwa ngononophelo kwemathiriyeli, ukuphunyezwa kolawulo olusebenzayo lwe-thermal kunye neendlela zokunciphisa uxinzelelo lomatshini, uyilo lokuthembeka, kunye nokusetyenziswa kweenkqubo zokuvelisa ezomeleleyo. Gcina ukhumbule ukuba indlela eqhutywe kakuhle yokujongana nale miba inokuqinisekisa ukuzinza kunye nokuthembeka kwe-PCB ye-6-layer, ngaloo ndlela iqinisekisa ukusebenza kwayo ngempumelelo kwiintlobo ezahlukeneyo zezicelo ezibalulekileyo.
