Ukukhiqiza kwe-RT duroid 5870 PCB

Ukukhiqizwa kwe-RT duroid 5870 PCB kudinga indlela yokwenziwa eqashelwa yi-PTFE ngoba umphumela we-RF oqediwe uncike ekuphathweni kwezinto, ukulungiswa kwemigodi kanye ne-copper interfaces kanye ne-laminate uqobo. Ukulawula okubaluleke kakhulu ukuphindaphindwa kokwakhiwa okuqediwe. I-RT/duroid 5870 ikhethwa lapho indlela ye-RF idinga ukulahlekelwa okuphansi, ukungaguquguquki kwe-dielectric okuphansi kanye nokuqina kwemvamisa ebanzi, kodwa indlela yokukhiqiza ayithetheleli kangako kune-thermoset laminate ejwayelekile. Isakhiwo esifanayo esicebile nge-PTFE esisekela ama-antenna e-wideband kanye nemigqa emide ye-microwave sidinga ukuphathwa ngokucophelela, ukusebenza kwemigodi, ukunamathela kwethusi kanye nokusekelwa kwemishini. Ukuze uqhathanise nokwakhiwa kwesekethe ye-RT/duroid 5880 , hlola ukwakhiwa kwe-dielectric okukhishwe kanye nemodeli ye-RF yento ngayinye.

I-Highleap Electronics ikhiqiza ama-prototype e-RT/duroid 5870 PCB kanye nama-PCB okukhiqiza, okuhlanganisa imigodi eboshwe ngamapulangwe, ukuqaliswa komphetho, ukwakhiwa okusekelwe ngensimbi kanye nokuhlanganiswa kwe-RF okukhethwa kukho. I-Highleap Electronics igxila ezindabeni zokukhiqiza ezinquma ukuthi inzuzo kagesi iyasinda yini ekukhiqizweni.

Ukwenziwa kwe-RT/duroid 5870 kugxile ekwakhiweni kwebhodi le-PTFE elinokulahlekelwa okuncane. Ukubhoboza, ukulungiswa kwemigodi, ukwenziwa kwensimbi, ukulawula ubukhulu kanye ne-geometry yokugcina ye-RF kufanele kubuyekezwe njengenqubo eyodwa ngoba ukwakheka okusekelwe ku-PTFE akulandeli izibikezelo zokwenziwa ezifanayo njenge-FR-4 ejwayelekile.

Kungani Onjiniyela Bekhetha i-RT/duroid 5870 ye-Broadband RF PCB

I-Dk ephansi isekela imigqa yokudlulisa ebanzi kanye nezinkambu ezigxile kancane kunezinto eziningi ze-Dk eziphezulu. Lokho kungaba usizo kuma-antenna e-broadband, amanethiwekhi okuphakelayo amade, i-stripline, amanethiwekhi azwela isigaba kanye nehadiwe ye-RF yendiza. Akuyona ngokuzenzakalelayo ukukhetha okungcono kakhulu kwesekethe emfushane noma elula ngomshini; i-thermoset laminate inganikeza ukulahlekelwa okwanele ngokwenziwa nokuhlanganiswa okulula. Uma ucabangela omunye umzila we-PTFE we-Dk ephansi, ukukhetha i-laminate engu-5880 kanye nokwakhiwa kufanele kuqedwe ngaphambi kokusebenzisa kabusha umsebenzi wobuciko we-5870.

Ithusi liba yingxenye yesinqumo esibalulekile

Uma ukulahlekelwa yi-dielectric sekuphansi, ukulahlekelwa yi-conductor kungabusa. I-foil yethusi ekhethiwe, i-plating yokugcina kanye nokuphela kwendawo kufanele kuhambisane nokulinganisa kanye nencazelo yokuthenga. I-foil ebushelelezi ingathuthukisa ukulahlekelwa, kodwa ukutholakala, ukunamathela kanye nokuziphatha kwe-etch nakho kubalulekile. Ibhodi akufanele licashunwe ku-“5870” kuphela lapho ukwakhiwa kwethusi kubaluleke kakhulu ngogesi.

Ububanzi bezinto ezibonakalayo: I-Highleap Electronics ingumkhiqizi we-PCB kanye nomhlanganisi wesakhiwo esichazwe lapha. URogers kanye namagama ebanga elibhekiselwe kuwo akhomba izinto ezicacisiwe futhi akuyona incazelo yokukhiqiza izinto ze-Highleap.

Izinselele Zokwenza i-PTFE PCB

Ukwakhiwa kwe-PTFE ethambile kudinga ukwesekwa okulawulwayo ngesikhathi sokuthwebula izithombe, ukubhoboza, ukuhambisa kanye nokuhlanganisa. Umthwalo we-clamp, i-screw torque kanye nokucindezela kwesixhumi kungadala ukukhukhuleka uma umklamo womshini ugxila ekucindezelekeni. Ukuphathwa kwamathuluzi kanye namaphaneli kufanele kunciphise ukuphambuka, futhi ibhodi eliqediwe kufanele lihlolwe ngokumelene nama-datum abalulekile endlini kanye nokuqaliswa.

Ukubhoboza kanye nokusebenza kwe-PTFE

Izimbobo eziqinisiwe ezinokwethenjelwa zincike endleleni yokulungiselela ehambisana ne-PTFE. Ikhwalithi yokubhoboza, ukususwa kwe-smear noma ukusebenza, ukufakwa kwethusi kanye ne-plating yokugcina kumele kulawulwe njengenqubo eyodwa. Indlela eqondile ingancika ekwakhiweni kanye ne-geometry yembobo. Imbobo eqediwe kumele ihlolwe ngokuhlolwa kukagesi, futhi lapho kudingeka, ihlolwe nge-microsection kunokuba ithathwe njengophawu lwezinto ezibonakalayo.

Imiphetho, ukuqalisa kanye nokusekelwa kwensimbi

Izixhumi zomphetho kanye nemiphetho eboshwe ngepulasitiki zidinga umzila ozinzile kanye neplati ngoba ukuqaliswa kungase kuhlale eduze kohlaka. Isisekelo sensimbi senezela ukuqina kanye nokusabalala kokushisa kodwa futhi sethula izidingo zokubopha kanye nokuba yisicaba. Isendlalelo sokubopha kanye nokucindezela komhlangano akumele kuphazamise isikhala se-RF dielectric.

Ikhasi lezinsizakalo zokwenziwa kwe-PCB ezivame kakhulu ze-Highleap linikeza umongo owengeziwe mayelana ne-PTFE kanye nokwakhiwa kwe-RF okuxubile.

Izinto Okucatshangelwayo Zokuhlanganisa Nokwemvelo ze-5870

I-5870 ingakhethwa ngemikhiqizo yokuxhumana yezindiza, i-cryogenic, ezwela umswakama noma i-broadband, kodwa ukuhlanganiswa okugcwele kusanquma ukuziphatha kwensimu. I-torque yesixhumi, ukwesekwa kwendlu, ukunamathela, ukunamathisela kanye nokujikeleza kokushisa kufanele kubuyekezwe ndawonye. Ibhodi elincane elingasekelwa ngomshini lingaguquguquka ngesikhathi sokuhlanganiswa ngisho nalapho izakhiwo zalo zikagesi zifanelekile.

Emikhiqizweni ehlanganisiwe, i-Highleap ingaxhumanisa ukutholakala kwezingxenye, i-SMT noma ukuhlanganiswa kwembobo, ukufakwa kwesixhumi kanye nokuhlolwa okuvunyelwene ngakho. Izinto ezifakiwe kufanele zisekele ibhodi ngaphandle kokushintsha isimo sayo somshini esihlosiwe. Ukupakishwa nokuthunyelwa kufanele futhi kuvimbele ukugoba noma ukulayisha endaweni.

Ukungenzeka Kokukhiqiza Ngaphambi Kokukhiqiza kwe-RT/duroid 5870

Ukubuyekezwa kokwenzeka kuqhathanisa ukulahlekelwa okudingekayo kanye nomkhawulokudonsa we-bandwidth nezindleko zokucubungula i-PTFE, ukwakhiwa kwethusi, ukwesekwa kwemishini kanye neziqu. Kwamanye amaphrojekthi, i-5880, i-RO3003 noma izinto ze-thermoset zingaba usizo kakhulu. Kwamanye, i-5870 iyafaneleka ngoba i-RF margin ayikwazi ukubekezelela ukulahlekelwa okuphezulu noma ukuhlushwa kwensimu okunamandla.

Ubufakazi bokwakhiwa okuphindaphindwayo

Iphakheji yokukhululwa kufanele ifake izinto zokwakha kanye nethusi, ukujiya okuqediwe, i-geometry ye-RF, imigodi, izidingo zomphetho, imininingwane yokubopha noma yokusekela, ukuqeda kwendawo, ama-datum emishini kanye nendlela yokuhlola. I-Highleap inganikeza i-prototype kanye nokwenziwa kwevolumu ephansi ngaphambi kokuba umklamo udluliselwe ekukhiqizweni okuphindayo. I-Highleap ibuyekeza ukubhoboza, ukulungiswa kwe-desmear noma indawo, ukunamathela kwethusi, i-lamination kanye ne-geometry ye-RF njengeketanga elilodwa lenqubo. Isihloko sokuqala singasetshenziswa ukuqinisekisa ukwakhiwa kwembobo kanye nezakhiwo ze-impedance ngaphambi kokukhulula ukukhiqizwa okuphindayo. Amanani empahla eqondile kufanele ahlolwe ngokumelene nemibhalo yamanje yomhlinzeki webanga elicacisiwe kanye nokwakhiwa.

Imibuzo yokuqamba engu-5870

Ingabe i-5870 ingaphathwa njenge-FR-4? Cha. Kudingeka ukulungiswa kwe-PTFE kanye nokusekelwa kwemishini.

Ingabe ithusi elibushelelezi kakhulu liyadingeka njalo? Hhayi njalo. Kuncike kwisabelomali sokulahlekelwa, i-geometry, ukutholakala kanye nezidingo zokunamathela. Ukuze uthole ikhotheshini, nikeza ibanga, ukujiya, ithusi, ubuchwepheshe bembobo, ukuqeda, ibhendi yokusebenza kanye nobuningi. Sho noma yisiphi isidingo sokulinganisa i-RF ukuze ikhotheshini ihlanganise ukuqinisekiswa okudingekayo kunokuba ucabange ukuthi ukuhlolwa okujwayelekile kwe-FR4 kwanele.
