Zeziphi iindlela zokungaphumeleli eziqhelekileyo zeebhodi eziguquguqukayo?

Iibhodi zesekethe eziqinileyo zineenzuzo ezizodwa zokuyila, ukudibanisa ukuzinza kweebhodi eziqinileyo kunye nokuguquguquka kweesekethe eziguquguqukayo. Olu yilo oluxutyiweyo lwenza ukuba i-elektroniki icwecwe kwaye isebenze ngeendlela ezininzi, iyenze ilungele usetyenziso olwahlukeneyo olubandakanya i-aerospace, izixhobo zonyango kunye ne-elektroniki yabathengi. Nangona kunjalo, njengalo naliphi na elinye icandelo le-elektroniki, iibhodi zesekethe eziqinileyo azikhuselekanga ekungaphumeleli. Ukuqonda iindlela eziqhelekileyo zokungaphumeleli kunokunceda iinjineli zenze iibhodi zesekethe ezinamandla, ezithembekileyo. Kweli nqaku, siza kuphonononga ezona ndlela zixhaphakileyo zokungaphumeleli kweebhodi zesekethe eziqinileyo kunye nokubonelela ngeembono malunga nendlela yokuthintela oku kusilela.

1. Ukudinwa kwesekethe ethambileyo:

Enye yeenzuzo eziphambili ze-rigid-flex panels kukuguquguquka kwazo, ezivumela ukuba zigobe kwaye zilungelelanise imilo enzima. Nangona kunjalo, ukugoba okuqhubekayo kunye nokugoba kunokubangela ukudinwa kwesekethe ye-flex ngokuhamba kwexesha. Oku kunokubangela ukuqhekeka okanye ukuphuka kwimizila yobhedu, okukhokelela kwiisekethe ezivulekileyo okanye ukudibanisa okuphakathi. Ukuthintela ukukhathala kwesekethe ye-flex, iinjineli kufuneka ziqwalasele ngokucophelela i-radius ye-bend kunye nenani lemijikelezo yokugoba ibhodi iya kuba nayo ngexesha lobomi bayo benkonzo. Ukomeleza iisekethe eziguquguqukayo kunye neziseko zokuxhasa ezongezelelweyo okanye ukuphumeza uyilo oluguquguqukayo oluguquguqukayo lunokunceda ukunciphisa ukusilela okunxulumene nokudinwa.

2. Ulwaleko:

I-Delamination ibhekiselele ekuhlukaneni kweeleyile ezahlukeneyo ngaphakathi kwebhodi yesekethe engqongqo. Oku kunokwenzeka ngenxa yezizathu ezahlukeneyo, kubandakanywa ukudibanisa okungahambi kakuhle phakathi kweengqimba, ukuhamba ngebhayisikili yeqondo lokushisa, okanye uxinzelelo lomatshini. I-Delamination inokubangela iifutshane zombane, ukuvula, okanye ukunciphisa ukuthembeka kwebhodi. Ukunciphisa umngcipheko we-delamination, iinkqubo ezifanelekileyo zokulahla kufuneka zilandelwe ngexesha lenkqubo yokuvelisa. Oku kubandakanya ukusebenzisa izixhobo ezikumgangatho ophezulu zokubopha, ukulawula iiparamitha ze-lamination, kunye nokuqinisekisa ixesha elaneleyo lokunyanga. Ukongeza, ukuyila i-stackups ngokusasazwa kobhedu olulungeleleneyo kunye nokuthintela utshintsho olugqithileyo lobushushu kunokuncedisa ukuthintela i-delamination.

3. Uxinzelelo lweThermomechanical:

Iibhodi ze-Rigid-flex zihlala zifumana uxinzelelo olubalulekileyo lwe-thermomechanical ngexesha lobomi babo benkonzo. Olu xinzelelo lunokubangelwa kukutshintsha kobushushu, ukufuma, okanye ukothuka komatshini kunye nokungcangcazela. Uxinzelelo lwe-Thermo-mechanical lunokubangela ukuqhekeka okanye ukungaphumeleli kwe-solder, kubangele imiba yokuthembeka kombane. Ukunciphisa ukungaphumeleli okunxulumene noxinzelelo lwe-thermomechanical, iinjineli kufuneka zikhethe ngokucophelela kwaye zifanelekele izinto eziphathekayo kunye ne-coefficient efanelekileyo yokwanda kwe-thermal (CTE) kuluhlu ngalunye lwebhodi e-rigid-flex. Ukongezelela, ukuphumeza iindlela ezifanelekileyo zokulawula i-thermal, ezifana nokusebenzisa i-heat sink okanye i-thermal vias, kunokuncedisa ukukhupha ukushisa kunye nokunciphisa uxinzelelo kwibhodi yesekethe.

4. Ungcoliseko kunye nomhlwa:

Ungcoliseko kunye nomhlwa ziindlela ezixhaphakileyo zokungaphumeleli kuso nasiphi na isixhobo sombane, kwaye iibhodi eziguquguqukayo azikho ngaphandle. Ungcoliseko lunokwenzeka ngexesha lenkqubo yokuvelisa okanye ngenxa yezinto ezisingqongileyo ezifana nokufuma okanye ukuvezwa kweekhemikhali. Kwelinye icala, ubukho bokufuma okanye iigesi ezityiwayo zidla ngokukhawulezisa umhlwa. Zombini ungcoliseko kunye nokubola kunokubangela ukuba iibhodi zeesekethe zibe mfutshane okanye zithobe ukusebenza. Ukuthintela ezi ndlela zokungaphumeleli, amanyathelo angqongqo okulawula umgangatho kufuneka aphunyezwe ngexesha lenkqubo yokuvelisa. Ukongeza, iingubo ezihambelanayo okanye i-encapsulation inokubonelela ngomqobo okhuselayo kwizinto ezingqongileyo.

5. Isidibanisi kunye nokusilela kokudityaniswa kwe-solder:

Iziqhagamshelo kunye nezihlanganisi ze-solder zibaluleke kakhulu kwiibhodi zesekethe eziqinileyo. Ukungaphumeleli kwezi zixhobo kunokubangela uxhulumaniso oluphakathi, iisekethe ezivulekileyo, okanye ukunciphisa ingqibelelo yesignali. Izizathu eziqhelekileyo zokungaphumeleli kokudibanisa kunye ne-solder edibeneyo ibandakanya uxinzelelo lomatshini, ukukhwela ibhayisekile kobushushu, okanye ubuchule obungafanelekanga bokuthengisa. Ukuqinisekisa ukuthembeka kweziqhagamshelo kunye nezihlanganisi ze-solder, iinjineli kufuneka zikhethe amacandelo akumgangatho ophezulu, ziqinisekise ukulungelelaniswa okufanelekileyo kunye nokulungelelana, kwaye zilandele izikhokelo ezicetyiswayo zokuthengisa ezifana nobushushu obuchanekileyo, ubude bexesha, kunye nesicelo se-flux.

Isishwankathelo, ngelixa iibhodi zesekethe eziqinileyo zibonelela ngeenzuzo ezininzi, zichaphazeleka kwiindlela ezithile zokungaphumeleli. Ukuqonda ezi ndlela zokungaphumeleli eziqhelekileyo kubalulekile ekuyileni iisekethe ezithembekileyo nezomeleleyo. Ngokuqwalasela izinto ezinjengokukhathala kwesekethe ye-flex, i-delamination, uxinzelelo lwe-thermomechanical, ungcoliseko kunye nokugqwala, kunye nesinxibelelanisi kunye nokusilela okudibeneyo kwe-solder, iinjineli zinokusebenzisa amanyathelo afanelekileyo okuthintela ngexesha loyilo, ukuvelisa kunye nenqanaba lovavanyo. Ngokunika ingqwalasela efanelekileyo kwezi ndlela zokungaphumeleli, iibhodi zeesekethe eziqinileyo zinokubonelela ngokusebenza okuphezulu kunye nobomi obude benkonzo kwiinkqubo ezahlukeneyo.
