IRigid-Flex PCB Boards: Inkqubo yeBonding iqinisekisa ukuzinza kunye nokuthembeka

Njengoko itekhnoloji iqhubela phambili ngesantya esingazange sibonwe ngaphambili, imfuno yezixhobo zombane ezixineneyo, ezikhaphukhaphu nezibhetyebhetye ngakumbi ziye zanda.Ukuhlangabezana nale mfuno, uphuhliso lweebhodi zesekethe eziqinileyo ziye zaba yinto entsha kwishishini le-elektroniki.Ezi bhodi zidibanisa ukuguquguquka kweesekethe eziguquguqukayo kunye nokuqina kweebhodi eziqinileyo, ezizenza zilungele uluhlu olubanzi lwezicelo ezibandakanya i-aerospace, izixhobo zonyango, kunye ne-electronics yabathengi.

Inkalo ebalulekileyo yokuvelisa iibhodi zesekethe eziqinileyo yinkqubo yokudibanisa.Inkqubo idlala indima ebalulekileyo ekuqinisekiseni uzinzo kunye nokuthembeka kwezi bhodi njengoko idibanisa ngokuqinileyo iindawo eziguquguqukayo kunye eziqinileyo kunye.Kulo myalezo weblogi, uCapel uya kukhangela kwiinkcukacha zenkqubo yokudibanisa, ukuxoxa ngeziphumo zayo, ubuchule kunye nokuqwalaselwa.

Qonda intsingiselo:

Inkqubo yokudibanisa ibaluleke kakhulu ekugcineni ingqibelelo yesakhiwo seebhodi zesekethe eziqinileyo.Ibandakanya ukusetyenziswa kwezinto ezinamathele phakathi kwesekethe eguquguqukayo kunye ne-substrate eqinile, eyenza ibhondi eqinile enokumelana nezinto ezisingqongileyo, uxinzelelo lomatshini, kunye nokutshintsha kweqondo lokushisa.Ngokusisiseko, i-adhesive ayigcini nje ukubamba iileyile kunye, kodwa ikhusela isiphaluka kumonakalo onokwenzeka.

Khetha imathiriyeli encamathelayo efanelekileyo:

Ukukhetha izinto ezifanelekileyo zokubambelela kubalulekile ekuqinisekiseni ukuthembeka kwexesha elide kunye nokusebenza kweebhodi zesekethe eziqinileyo.Izinto ezininzi kufuneka ziqwalaselwe xa ukhetha i-adhesive, njengokuhambelana nezinto ezisetyenzisiweyo, ukusebenza kwe-thermal, ukuguquguquka, kunye neemfuno ezithile zesicelo.

I-Polyimide-based adhesives isetyenziswa ngokubanzi ngenxa yokuzinza kwayo kwe-thermal, ukuguquguquka, kunye nokuhambelana nezinto zombini eziqinileyo kunye neziguquguqukayo.Ukongeza, izinto zokuncamathelisa ezisekwe kwi-epoxy zisetyenziswa kakhulu ngenxa yamandla azo aphezulu, ukumelana nokufuma, kunye neekhemikhali.Kubalulekile ukubonisana nomenzi we-adhesive kunye nomenzi webhodi yesekethe engqongqo-flex ukumisela eyona nto ifanelekileyo kwisicelo esithile.

Ubuchwephesha beSicelo sokuncamathelisa:

Ukusetyenziswa ngempumelelo kwe-adhesives kufuna ingqalelo kwiinkcukacha kunye nokuthotyelwa kobuchule obufanelekileyo.Apha siphonononga ezinye zeendlela eziphambili ezisetyenziswa kwinkqubo yokudibanisa ibhodi yesekethe engqongqo:

1. Ushicilelo lwesikrini:

Ukuprintwa kwesikrini bubuchule obudumileyo bokusebenzisa i-adhesives kwiibhodi zeesekethe.Kubandakanya ukusebenzisa i-stencil okanye isikrini se-mesh ukudlulisa i-adhesive kwiindawo ezithile zebhodi.Le ndlela ivumela ukulawulwa ngokuchanekileyo kobuninzi be-adhesive kunye nokusabalalisa, ukuqinisekisa ukuba ibhondi ehambelanayo neyithembekileyo.Ukongeza, ukuprintwa kwesikrini kunokuzenzekela, ukuphucula ukusebenza kakuhle kwemveliso kunye nokunciphisa impazamo yomntu.

2. Ukuhambisa:

Ukukhupha i-adhesives kubandakanya ukusetyenziswa okuchanekileyo kwezinto usebenzisa izixhobo zokuzikhupha ezizenzekelayo.Le teknoloji ivumela ukubekwa okuchanekileyo kunye nokuzaliswa kwe-adhesive, ukunciphisa umngcipheko we-voids kunye nokuqinisekisa amandla amakhulu ebhondi.Unikezelo luhlala lusetyenziselwa uyilo lwebhodi yesekethe entsonkothileyo okanye ntathu-ntathu apho ushicilelo lwesikrini lungenakwenzeka.

3. Lamination:

I-Lamination yinkqubo yesandwiching umaleko wesekethe oguquguqukayo phakathi kweeleya ezimbini eziqinileyo kunye ne-adhesive efakwe phakathi.Le teknoloji iqinisekisa ukuba i-adhesive isasazwa ngokulinganayo kwibhodi yonke, ukwandisa ukusebenza kwebhondi.I-Lamination ifaneleka ngokukodwa kwimveliso yomthamo ophezulu kuba ivumela iibhodi ezininzi ukuba zidityaniswe kunye ngexesha elinye.

Amanqaku ngenkqubo yokudibanisa:

Nangona ukuqonda iindlela ezahlukeneyo zokusetyenziswa kwe-adhesive kubalulekile, kukho ezinye izinto ezongezelelweyo ezifaka isandla kwimpumelelo yenkqubo yokunamathela ngokubanzi.Ezi zinto zidlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nokuthembeka kweebhodi zesekethe eziqinileyo.Makhe sihlolisise ezinye zezi ngqwalasela:

1. Ucoceko:

Kubalulekile ukuqinisekisa ukuba zonke iindawo, ngakumbi iileya zesekethe eziguquguqukayo, zicocekile kwaye azinangcoliseko ngaphambi kokufaka i-adhesive.Nokuba amasuntswana amancinane okanye iintsalela zinokuphazamisa ukuncamathelisa, okukhokelela ekuncipheni ukuthembeka okanye ukungaphumeleli.Iinkqubo ezifanelekileyo zokucoca umphezulu kufuneka ziphunyezwe, kubandakanywa ukusetyenziswa kwe-isopropyl alcohol okanye izisombululo ezikhethekileyo zokucoca.

2. Iimeko zokunyanga:

Iimeko zokusingqongileyo ngexesha lokunyanga okuncamathelisayo zibalulekile ekufezekiseni ukomelela okukhulu kwebhondi.Izinto ezifana nobushushu, ukufuma kunye nexesha lokunyanga kufuneka zilawulwe ngononophelo ukuhlangabezana nezikhokelo zomenzi wokuncamathelisa.Ukuphambuka kwiimeko ezicetyiswayo zokunyanga kunokubangela ukunamathela okungahambi kakuhle okanye ukusebenza kwebhondi.

3. Iingqwalasela zoxinzelelo lomatshini:

Iibhodi zesekethe eziguquguqukayo zihlala ziphantsi koxinzelelo olwahlukeneyo lomatshini njengokugoba, ukujija kunye nokungcangcazela ngexesha lobomi babo benkonzo.Kubalulekile ukuqwalasela ezi zinto ngexesha lenkqubo yokudibanisa.Izinto zokudibanisa kufuneka zikhethwe ngokuguquguquka okuphezulu kunye nokuchasana kokukhathala okulungileyo ukuqinisekisa ukuba ibhondi inokumelana noxinzelelo lomatshini ngaphandle kokungaphumeleli.

Inkqubo yokudibanisa kwi-rigid-flex circuit board board ibaluleke kakhulu ekufezekiseni uzinzo, ukuqina kunye nokuthembeka.Ukukhethwa kwezinto ezincamathelayo ezichanekileyo kunye nobuchule obufanelekileyo bokusebenzisa kunye nokunyameka kunokuqinisekisa ukusebenza kwexesha elide kwezi bhodi nakwizicelo ezinzima kakhulu.

Njengoko itekhnoloji iqhubeka nokuvela, imfuno yezixhobo zombane eziphucukileyo neziphucukileyo ziya kuqhubeka.Inkqubo yokudibanisa idlala indima ebalulekileyo ekuhlangabezaneni nale mfuno ngokuvelisa iibhodi zesekethe ezithembekileyo kunye neziguquguqukayo eziqinileyo.Ngokuqonda ukubaluleka kwenkqubo yokudibanisa kunye nokuyisebenzisa ngokuchanekileyo, abavelisi banokwenza izixhobo zombane ezinqamlekileyo ezihamba phambili kwizinto ezintsha zeteknoloji.
