Ibhodi yeFPC ebhetyebhetyeluhlobo lwesekethe eyenziwe kumphezulu wokugqiba oguquguqukayo, kunye okanye ngaphandle koqweqwe lokugquma (oludla ngokusetyenziswa ukukhusela iisekethe zeFPC).Ngenxa yokuba ibhodi ethambileyo ye-FPC inokugotywa, igoqwe okanye iphindaphindwe intshukumo ngeendlela ezahlukeneyo, xa kuthelekiswa nebhodi enzima eqhelekileyo (PCB), ineengenelo zokukhanya, ezibhityileyo, eziguquguqukayo, ngoko ke ukusetyenziswa kwayo kubanzi ngakumbi nangakumbi, ngoko ke kufuneka sinikele ingqalelo kwinto esiyiyileyo, ezi zincinci zilandelayo zenza ukutsho ngokweenkcukacha.
Kuyilo, i-FPC ihlala ifuna ukusetyenziswa kunye ne-PCB, kunxibelelwano phakathi kwezi zibini zihlala zithatha ibhodi ukuya kwibhodi isinxibelelanisi, isinxibelelanisi kunye nomnwe wegolide, i-HOTBAR, ibhodi yokudibanisa ethambileyo nenzima, imowudi ye-welding ye-manual yokudibanisa, ngokutsho indawo yesicelo eyahlukileyo, umyili unokwamkela imo yokudibanisa ehambelanayo.
Kwizicelo ezisebenzayo, kumiselwa ukuba ngaba ukukhuselwa kwe-ESD kuyafuneka ngokweemfuno zesicelo.Xa ubhetyebhetye lwe-FPC lungekho phezulu, ulusu lobhedu oluqinileyo kunye nendawo etyebileyo ingasetyenziselwa ukuyifeza.Xa imfuno yokuguquguquka iphezulu, i-mesh yobhedu kunye ne-conductive paste yesilivere ingasetyenziswa
Ngenxa yokuthamba kwepleyiti ethambileyo ye-FPC, kulula ukwaphuka phantsi koxinzelelo, ke ezinye iindlela ezikhethekileyo ziyafuneka kukhuseleko lweFPC.
Iindlela eziqhelekileyo zezi:
1. Ubuncinci be-radius ye-Angle yangaphakathi ye-contour eguquguqukayo yi-1.6mm.Okukhona iradiyasi inkulu, kokukhona iphezulu ukuthembeka kunye nokomelela kokumelana nokukrazula.Umgca unokongezwa kufuphi nomda wepleyiti kwikona yesimo ukukhusela i-FPC ukuba ikrazulwe.
2. Iintanda okanye iigrooves kwi-FPC kufuneka ziphele kumngxuma ojikelezayo ongekho ngaphantsi kwe-1.5mm ububanzi, nokuba iiFPCS ezimbini ezimeleneyo kufuneka zihanjiswe ngokwahlukeneyo.
3. Ukuze ufezekise ukuguquguquka okungcono, indawo yokugoba kufuneka ikhethwe kwindawo enobubanzi obufanayo, kwaye uzame ukuphepha ukuhluka kobubanzi be-FPC kunye nokuxinana komgca ongalinganiyo kwindawo yokugoba.
Ibhodi ye-STIffener isetyenziselwa inkxaso yangaphandle.Izinto zebhodi ye-STIffener ibandakanya i-PI, i-Polyester, i-fiber yeglasi, i-polymer, i-aluminium sheet, i-steel sheet, njl. Uyilo olufanelekileyo lwesikhundla, indawo kunye nezinto eziphathekayo zepleyiti yokuqinisa idlala indima enkulu ekuphepheni ukukrazula kwe-FPC.
5. Kuyilo lwe-FPC ye-multi-layer, uyilo lwe-gap stratification yomoya kufuneka lwenziwe kwiindawo ezifuna ukugoba rhoqo ngexesha lokusetyenziswa kwemveliso.Izinto zePI eziThin kufuneka zisetyenziswe kangangoko ukunyusa ukuthamba kweFPC kwaye kuthintelwe i-FPC ukuba ingaphumi kwinkqubo yokugoba ngokuphindaphindiweyo.
6. Ukuba indawo iyavuma, indawo yokuncamathelisa enamacala amabini kufuneka iyilwe ngokudityaniswa komnwe wegolide kunye nesihlanganisi ukuthintela umnwe wegolide kunye nesihlanganisi ukuba singawi ngexesha lokugoba.
7. I-FPC yokubeka umgca wesikrini wesilika kufuneka uyilwe kuqhagamshelo phakathi kwe-FPC kunye nesinxibelelanisi ukuthintela ukutenxa kunye nokufakwa ngokungafanelekanga kwe-FPC ngexesha lokudityaniswa.Ivumela ukuhlolwa kwemveliso.
Ngenxa yobungcali be-FPC, nikela ingqalelo kula manqaku alandelayo ngexesha lokufakela iikheyibhuli:
Imithetho yendlela: Nikeza kuqala ekuqinisekiseni umzila wesignali ogudileyo, landela umgaqo wemingxuma emifutshane, ethe tye kunye nembalwa, nqanda indlela ende, ebhityileyo kunye nesetyhula kangangoko kunokwenzeka, thatha imigca ethe tye, ethe nkqo kunye ne-45 degree njengeyona nto iphambili, thintela umgca we-Angle ongenamkhethe. , goba inxalenye yomgca weradian, ezi nkcukacha zingentla zimi ngolu hlobo lulandelayo:
1. Ububanzi bomgca: Ukuqwalasela ukuba iimfuno zobubanzi bomgca wentambo yedatha kunye nentambo yamandla ayihambelani, indawo ephakathi egcinwe kwi-wiring yi-0.15mm.
2. Isithuba somgca: Ngokomthamo wemveliso yabaninzi abavelisi, isithuba somgca woyilo (Pitch) yi-0.10mm.
3. Umda womgca: umgama phakathi komgca ongaphandle kunye ne-contour ye-FPC yenzelwe ukuba yi-0.30mm.Indawo enkulu ivumela, ingcono
4. Ifillet yangaphakathi: Ifillet encinci yangaphakathi kwicontour yeFPC iyilwe njengeradius R=1.5mm.
5. I-conductor i-perpendicular ukuya kwicala lokugoba
6. Ucingo kufuneka ludlule ngokulinganayo kwindawo yokugoba
7. Umqhubi kufuneka agubungele indawo yokugoba kangangoko kunokwenzeka
8. Akukho ntsimbi eyongezelelweyo yokubeka kwindawo yokugoba (iingcingo kwindawo yokugoba azikho i-plating)
9. Gcina ububanzi bomgca bufana
10. Ukufakwa kweekheyibhuli kweephaneli ezimbini akunako ukutyhutyha ukwenza imilo ethi "I".
11. Nciphisa inani leengqimba kwindawo egobileyo
12. Akusayi kubakho kwimingxuma kunye nemingxuma eyenziwe ngesinyithi kwindawo yokugoba
13. I-axis yeziko lokugoba iya kusekwa embindini wocingo.I-coefficient yezinto eziphathekayo kunye nobukhulu kumacala omabini omqhubi kufuneka afane ngokusemandleni.Oku kubaluleke kakhulu kwizicelo zokugoba eziguqukayo.
14. I-Horizontal torsion ilandela le migaqo ilandelayo ---- ukunciphisa icandelo lokugoba ukunyusa ukuguquguquka, okanye ukunyusa inxalenye yendawo ye-foil yobhedu ukwandisa ukuqina.
15. Iradiyasi egobayo yendiza ethe nkqo kufuneka yandiswe kwaye inani leeleya kwiziko lokugoba kufuneka lincitshiswe.
16. Kwiimveliso ezineemfuno ze-EMI, ukuba imigca yophawu lwemitha ephezulu yamaza ombane efana ne-USB kunye ne-MIPI ikwi-FPC, umaleko wefoyile yesilivere eqhutywayo kufuneka yongezwe kwaye isekelwe kwi-FPC ngokomlinganiselo we-EMI ukuthintela i-EMI.
