Nangona kunjalo, umbuzo oqhelekileyo ovelayo kukuba ingaba iibhodi eziguquguqukayo eziguquguqukayo zinokuthengiswa kwiindawo eziqhelekileyo zokunyuka komphezulu. Kule post yebhlog, siza kuphonononga esi sihloko ngokweenkcukacha kwaye sikunike ulwazi oludingayo.

Funda malunga neebhodi zesekethe eziqinileyo:

Ngaphambi kokuba singene kwisihloko se-soldering eqinile yeebhodi zesekethe eziguquguqukayo zisebenzisa izinto ezisemgangathweni zomgangatho wokunyuka, masiqale siqonde ukuba yintoni ibhodi yesekethe eqinileyo. Iibhodi zesekethe eziguquguqukayo ziyi-hybrid yetekhnoloji yesekethe eqinileyo kwaye eguquguqukayo, edibanisa ezona hlabathi zombini. Ziquka iileya ezininzi zeesekethe eziguquguqukayo eziqhotyoshelwe kwibhodi enye okanye ngaphezulu eqinile. Uyilo luvumela ukudala iisekethe eziyinkimbinkimbi ezinokugotywa, ukugotywa okanye ukujijwa kuxhomekeke kwiimfuno zesicelo.

Izinto eziluncedo kwiibhodi zesekethe eziqinileyo:

Iibhodi zesekethe eziguquguqukayo zibonelela ngeenzuzo ezininzi ngaphezulu kweesekethe zemveli eziqinileyo okanye eziguquguqukayo. Ezinye izibonelelo eziphambili ziquka:

1. Gcina indawo: Iibhodi zesekethe eziguquguqukayo zivumela ukuyila kwe-dimensional-dimensional, ebavumela ukuba bangene kwiindawo ezidibeneyo ngokufanelekileyo.Oku kunenzuzo ngakumbi kwizicelo apho indawo incinci.

2. Ukuthembeka: Ngenxa yoyilo lwalo olukhethekileyo, iibhodi zeesekethe eziqinileyo zine-interconnections ezimbalwa, ngaloo ndlela zinciphisa umngcipheko wokungaphumeleli okanye ukungasebenzi.Ukupheliswa kweziqhagamshelo kunye nokudibanisa okongeziweyo kwandisa ukuthembeka okupheleleyo kwebhodi.

3. Ukusebenza okuphuculweyo: Iibhodi zesekethe eziguquguqukayo ziphucula imfezeko yesiginali kunye nokunciphisa ukuphazamiseka kwe-electromagnetic (EMI) ngokusebenza kwazo okugqwesileyo kwe-high-frequency.Oku kubenza bafanelekele izicelo ezikhawulezayo.

4. Iindleko zokuSebenza: Nangona ixabiso eliphambili leebhodi zeesekethe eziqinileyo zingaba phezulu xa kuthelekiswa neesekethe zendabuko, ixabiso leyunithi liphantsi kakhulu ngenxa yokunciphisa ukudibanisa kunye neemfuno zokudibanisa.Ukongezelela, ukuthembeka kwezi bhodi kunciphisa iindleko zokugcina nokulungiswa kwexesha.

I-soldering eqinile-flex iibhodi zesekethe ezinezixhobo eziqhelekileyo zokunyuka komphezulu:

Ngoku, makhe siphendule umbuzo ophambili: Ngaba iibhodi eziguquguqukayo zinokuthengiswa ngezinto ezisemgangathweni zomgangatho wokunyuka? Impendulo nguewe. Iibhodi zesekethe eziguquguqukayo eziguquguqukayo zinokuthengiswa kusetyenziswa itekhnoloji ye-standard surface Mount (SMT). Nangona kunjalo, kukho ezinye izinto ekufuneka uzigcine engqondweni ukuze uqinisekise ukuwelda ngempumelelo.

1. Ukuhambelana kwezinto eziphathekayo: Kubalulekile ukuqinisekisa ukuba izinto ezisetyenziswe kwi-rigid-flex panel structures zihambelana neenkqubo ze-welding standard.I-flexibility ye-flex circuit layer akufanele ithintele inkqubo ye-solder, kwaye inxalenye eqinile kufuneka ikwazi ukumelana nokushisa okuphezulu okuhambelana ne-reflow soldering.

2. Iingqwalasela zoyilo: Uyilo oluchanekileyo lweebhodi zesekethe eziqinileyo zibalulekile kwi-soldering eyimpumelelo.Amacandelo kufuneka abekwe ngobuchule kuthathelwa ingqalelo ukuguquguquka kunye neemfuno zokugoba. Ukunikela ingqalelo kulawulo lwe-thermal kunye nokuqinisekisa uyilo olufanelekileyo lwephedi kunokuphucula ukuthembeka kwe-soldering.

3. Itekhnoloji yeNdibano: Ukusebenzisa itekhnoloji yendibano efanelekileyo ibalulekile kwi-soldering rigid-flex circuit boards.Uyilo oluchanekileyo lwe-stencil, i-solder paste deposition, kunye neeprofayili zokuphinda ziqhubeke zibalulekile ekufezekiseni amajoyina athembekileyo e-solder. Ukuhlolwa okubonakalayo kunye nokubekwa ngokuchanekileyo kwamacandelo nako kubalulekile ukuphepha ukusebenza kwakhona okanye iziphene.

Ukuququmbela:

Isishwankathelo, iibhodi zesekethe eziguquguqukayo ngokwenene zinokuthengiswa ngokwemigangatho yemigangatho yentaba. Nangona kunjalo, ukuhambelana kwezinto eziphathekayo, ukuyila, kunye neendlela zokuhlanganisa kufuneka ziqwalaselwe ngononophelo ukuze kuqinisekiswe ukuthembeka kunye nempumelelo yenkqubo ye-welding. Iibhodi zesekethe eziguquguqukayo zibonelela ngeenzuzo ezininzi ngaphezu kweesekethe zemveli eziqinileyo okanye eziguquguqukayo, zibenza zibe lukhetho oludumileyo lwezicelo ezahlukeneyo. Ngokuqonda iziseko ze-soldering rigid-flex circuit boards, ungasebenzisa amandla apheleleyo ethekhnoloji kwaye udale uyilo oluyilayo noluthembekileyo lwe-elektroniki.
